+# Governance Object
+A Governance Object (or "govObject") is a generic structure introduced in Dash Core v12.1 to allow for the creation of Budget Proposals, Triggers, and Watch Dogs. Class inheritance has been utilized to extend this generic object into a "Proposal" which is outlined throughout the remainder of this document. 
+
+### `new GovObject([govObjectData])`
+
+Creates a new `GovObject` object where:
+  - `govObjectData` - optional data (allowed types are `json`, `jsonString`, `hex`, `buffer`, `GovObject`)
+
+### Methods
+
+####  `dataHex`  
+Returns a dataHex representation (see above)
+####  `fromObject`  
+Allow to create a govObj from a json or stringifiedJSON obj
+####  `fromString`
+Allow to create a govObj from an hex string
+####  `checkedSerialize`
+Return an hexa string that can be used in dashd CLI
+####  `serialize`
+Return an hexa string
+####  `inspect`
+Returns a representation of the object
+####  `toBuffer`
+Return a buffer
+####  `fromBuffer`
+Allow to create a govObject from a buffer
+####  `shallowCopy`
+Allow to shallowCopy from another govObject
+
+## Governance Object Creation
+
+The following would create a blank govObject
+
+```javascript
+// instantiate a new govObject instance
+var govObject = new GovObject();
+```
+
+Budget Proposals can be created from a valid JSON object (stringified or not)
+
+```javascript
+var jsonProposal = {
+  name:"My First GovObject",
+  start_epoch:1483228800, //timestamp in seconds
+  end_epoch:1483747200, //Is valid if end_epoch>now_epoch
+  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
+  payment_amount:10,
+  type:1,//In this case, it will cast a proposal
+  url:"http://www.dash.org/proposal/first_proposal"
+};
+
+//Will instantiate the govObject given the json passed as arg for fromObject
+govObject = govObject.fromObject(jsonProposal);
+var govObject = new GovObject().fromObject(jsonProposal);
+
+
+//It worth mentioning that fromObject can also be a valid stringified json.
+var govObject = new GovObject().fromObject(JSON.stringify(jsonProposal));
+```
+
+Budget Proposals can be instantiated from a Buffer
+
+```javascript
+//Allow to create a new object from a given buffer
+var fromBuff = new GovObject(govObjBuffer);
+//Or
+var fromBuff = new GovObject().fromBuffer(govObjBuffer);
+
+//And from an hexa string
+var fromString = new GovObject("5b5b2270726f706f736...");
+//or
+var fromString = new GovObject().fromString("5b5b2270726f706f736...")
+```
+
+You can display a hex-encoded representation of a Budget Proposal with a simple "toString()"
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+var hexString = fromString.toString();
+//or
+var hexString = fromString.serialize();
+```
+
+Logging the object will also return a hex-encoded representation of the object
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+console.log(fromString) //<GovObject: 5b5b2270726f706f7...>
+//Or using the method
+fromString.inspect();
+```
+
+You could shallowcopy a first govObj into a second one
+
+```javascript
+proposal.url="http://dash.org/badUrl"
+var shallowCopyProposal = proposal.shallowCopy();
+proposal.url="http://dash.org/fixedUrl"
+
+console.log(proposal.url!==shallowCopyProposal.url)//return true as it's a copy
+console.log(proposal!==shallowCopyProposal)//return true
+```
+
+Finally you are able to get the dataHex from the object
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+fromString.dataHex()//Give a stringified json [['proposal',{name:"My First GovObject",....}]]
+
+//You could get back the given JSON object by doing so
+var JSONObject = JSON.parse(fromString.dataHex())[0][1]);
+```
+
+## GovObject Types:
+
+Each of theses types are inherited from govObject allowing the same methods to be callable.
+
+* Proposal `type:1` : Allow to create a proposal which inherit govObject method and overwrite them when needed
+
+```javascript
+var jsonProposal = {
+  name:"My First Proposal",
+  start_epoch:startDate,
+  end_epoch:endDate,
+  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
+  payment_amount:10,
+  type:1,
+  url:"http://www.dash.org"
+};
+
+var proposal = new Proposal();
+// create a new proposal from a stringified JSON object
+proposal = proposal.fromObject(JSON.stringify(jsonProposal));
+
+var shallowCopy = proposal.shallowCopy(); //As proposal inherits govObject
+
+//Return an hex equivalent of the proposal
+var hexProposal = proposal.serialize()
+```

+Allow to create a govObj from a json or stringifiedJSON obj
+####  `fromString`
+Allow to create a govObj from an hex string
+####  `checkedSerialize`
+Return an hexa string that can be used in dashd CLI
+####  `serialize`
+Return an hexa string
+####  `inspect`
+Returns a representation of the object
+####  `toBuffer`
+Return a buffer
+####  `fromBuffer`
+Allow to create a govObject from a buffer
+####  `shallowCopy`
+Allow to shallowCopy from another govObject
+
+## Governance Object Creation
+
+The following would create a blank govObject
+
+```javascript
+// instantiate a new govObject instance
+var govObject = new GovObject();
+```
+
+Budget Proposals can be created from a valid JSON object (stringified or not)
+
+```javascript
+var jsonProposal = {
+  name:"My First GovObject",
+  start_epoch:1483228800, //timestamp in seconds
+  end_epoch:1483747200, //Is valid if end_epoch>now_epoch
+  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
+  payment_amount:10,
+  type:1,//In this case, it will cast a proposal
+  url:"http://www.dash.org/proposal/first_proposal"
+};
+
+//Will instantiate the govObject given the json passed as arg for fromObject
+govObject = govObject.fromObject(jsonProposal);
+var govObject = new GovObject().fromObject(jsonProposal);
+
+
+//It worth mentioning that fromObject can also be a valid stringified json.
+var govObject = new GovObject().fromObject(JSON.stringify(jsonProposal));
+```
+
+Budget Proposals can be instantiated from a Buffer
+
+```javascript
+//Allow to create a new object from a given buffer
+var fromBuff = new GovObject(govObjBuffer);
+//Or
+var fromBuff = new GovObject().fromBuffer(govObjBuffer);
+
+//And from an hexa string
+var fromString = new GovObject("5b5b2270726f706f736...");
+//or
+var fromString = new GovObject().fromString("5b5b2270726f706f736...")
+```
+
+You can display a hex-encoded representation of a Budget Proposal with a simple "toString()"
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+var hexString = fromString.toString();
+//or
+var hexString = fromString.serialize();
+```
+
+Logging the object will also return a hex-encoded representation of the object
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+console.log(fromString) //<GovObject: 5b5b2270726f706f7...>
+//Or using the method
+fromString.inspect();
+```
+
+You could shallowcopy a first govObj into a second one
+
+```javascript
+proposal.url="http://dash.org/badUrl"
+var shallowCopyProposal = proposal.shallowCopy();
+proposal.url="http://dash.org/fixedUrl"
+
+console.log(proposal.url!==shallowCopyProposal.url)//return true as it's a copy
+console.log(proposal!==shallowCopyProposal)//return true
+```
+
+Finally you are able to get the dataHex from the object
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+fromString.dataHex()//Give a stringified json [['proposal',{name:"My First GovObject",....}]]
+
+//You could get back the given JSON object by doing so
+var JSONObject = JSON.parse(fromString.dataHex())[0][1]);
+```
+
+## GovObject Types:
+
+Each of theses types are inherited from govObject allowing the same methods to be callable.
+
+* Proposal `type:1` : Allow to create a proposal which inherit govObject method and overwrite them when needed
+
+```javascript
+var jsonProposal = {
+  name:"My First Proposal",
+  start_epoch:startDate,
+  end_epoch:endDate,
+  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
+  payment_amount:10,
+  type:1,
+  url:"http://www.dash.org"
+};
+
+var proposal = new Proposal();
+// create a new proposal from a stringified JSON object
+proposal = proposal.fromObject(JSON.stringify(jsonProposal));
+
+var shallowCopy = proposal.shallowCopy(); //As proposal inherits govObject
+
+//Return an hex equivalent of the proposal
+var hexProposal = proposal.serialize()
+```

- * Instantiate an address from an address String or Buffer, a public key or script hash Buffer,
- * or an instance of {@link PublicKey} or {@link Script}.
- *
- * This is an immutable class, and if the first parameter provided to this constructor is an
- * `Address` instance, the same argument will be returned.
- *
- * An address has two key properties: `network` and `type`. The type is either
- * `Address.PayToPublicKeyHash` (value is the `'pubkeyhash'` string)
- * or `Address.PayToScriptHash` (the string `'scripthash'`). The network is an instance of {@link Network}.
- * You can quickly check whether an address is of a given kind by using the methods
- * `isPayToPublicKeyHash` and `isPayToScriptHash`
- *
- * @example
- * ```javascript
- * // validate that an input field is valid
- * var error = Address.getValidationError(input, 'testnet');
- * if (!error) {
- *   var address = Address(input, 'testnet');
- * } else {
- *   // invalid network or checksum (typo?)
- *   var message = error.messsage;
- * }
- *
- * // get an address from a public key
- * var address = Address(publicKey, 'testnet').toString();
- * ```
- *
- * @param {*} data - The encoded data in various formats
- * @param {Network|String|number=} network - The network: 'livenet' or 'testnet'
- * @param {string=} type - The type of address: 'script' or 'pubkey'
- * @returns {Address} A new valid and frozen instance of an Address

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+ * Instantiate an address from an address String or Buffer, a public key or script hash Buffer,
+ * or an instance of {@link PublicKey} or {@link Script}.
+ *
+ * This is an immutable class, and if the first parameter provided to this constructor is an
+ * `Address` instance, the same argument will be returned.
+ *
+ * An address has two key properties: `network` and `type`. The type is either
+ * `Address.PayToPublicKeyHash` (value is the `'pubkeyhash'` string)
+ * or `Address.PayToScriptHash` (the string `'scripthash'`). The network is an instance of {@link Network}.
+ * You can quickly check whether an address is of a given kind by using the methods
+ * `isPayToPublicKeyHash` and `isPayToScriptHash`
+ *
+ * @example
+ * ```javascript
+ * // validate that an input field is valid
+ * var error = Address.getValidationError(input, 'testnet');
+ * if (!error) {
+ *   var address = Address(input, 'testnet');
+ * } else {
+ *   // invalid network or checksum (typo?)
+ *   var message = error.messsage;
+ * }
+ *
+ * // get an address from a public key
+ * var address = Address(publicKey, 'testnet').toString();
+ * ```
+ *
+ * @param {*} data - The encoded data in various formats
+ * @param {Network|String|number=} network - The network: 'livenet' or 'testnet'
+ * @param {string=} type - The type of address: 'script' or 'pubkey'
+ * @returns {Address} A new valid and frozen instance of an Address

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

Most of\nthe curve operations are performed on non-affine coordinates (either projective\nor extended), various windowing techniques are used for different cases.\n\nAll operations are performed in reduction context using [bn.js][1], hashing is\nprovided by [hash.js][2]\n\n### Related projects\n\n* [eccrypto][3]: isomorphic implementation of ECDSA, ECDH and ECIES for both\n  browserify and node (uses `elliptic` for browser and [secp256k1-node][4] for\n  node)\n\n#### LICENSE\n\nThis software is licensed under the MIT License.\n\nCopyright Fedor Indutny, 2014.\n\nPermission is hereby granted, free of charge, to any person obtaining a\ncopy of this software and associated documentation files (the\n\"Software\"), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to permit\npersons to whom the Software is furnished to do so, subject to the\nfollowing conditions:\n\nThe above copyright notice and this permission notice shall be included\nin all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS\nOR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

+     * Creates a `lodash` object which wraps `value` to enable implicit chaining.
+     * Methods that operate on and return arrays, collections, and functions can
+     * be chained together. Methods that retrieve a single value or may return a
+     * primitive value will automatically end the chain returning the unwrapped
+     * value. Explicit chaining may be enabled using `_.chain`. The execution of
+     * chained methods is lazy, that is, execution is deferred until `_#value`
+     * is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
+     * fusion is an optimization strategy which merge iteratee calls; this can help
+     * to avoid the creation of intermediate data structures and greatly reduce the
+     * number of iteratee executions.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.
+     *
+     * In addition to lodash methods, wrappers have `Array` and `String` methods.

+     * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
+     * and `where`
+     *
+     * The chainable wrapper methods are:
+     * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array of at least `200` elements
+     * and any iteratees accept only one argument. The heuristic for whether a
+     * section qualifies for shortcut fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.
+     *
+     * In addition to lodash methods, wrappers have `Array` and `String` methods.
+     *
+     * The wrapper `Array` methods are:

+     *
+     * The wrapper `String` methods are:
+     * `replace` and `split`
+     *
+     * The wrapper methods that support shortcut fusion are:

+     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

- *
- * This is an immutable class, and if the first parameter provided to this constructor is an

- * An address has two key properties: `network` and `type`. The type is either
- * `Address.PayToPublicKeyHash` (value is the `'pubkeyhash'` string)
- * or `Address.PayToScriptHash` (the string `'scripthash'`). The network is an instance of {@link Network}.
- * You can quickly check whether an address is of a given kind by using the methods
- * `isPayToPublicKeyHash` and `isPayToScriptHash`
- *
- * @example
- * ```javascript
- * // validate that an input field is valid
- * var error = Address.getValidationError(input, 'testnet');
- * if (!error) {
- *   var address = Address(input, 'testnet');
- * } else {
- *   // invalid network or checksum (typo?)
- *   var message = error.messsage;
- * }
- *
- * // get an address from a public key
- * var address = Address(publicKey, 'testnet').toString();
- * ```

Most of\nthe curve operations are performed on non-affine coordinates (either projective\nor extended), various windowing techniques are used for different cases.\n\nAll operations are performed in reduction context using [bn.js][1], hashing is\nprovided by [hash.js][2]\n\n### Related projects\n\n* [eccrypto][3]: isomorphic implementation of ECDSA, ECDH and ECIES for both\n  browserify and node (uses `elliptic` for browser and [secp256k1-node][4] for\n  node)\n\n#### LICENSE\n\nThis software is licensed under the MIT License.\n\nCopyright Fedor Indutny, 2014.\n\nPermission is hereby granted, free of charge, to any person obtaining a\ncopy of this software and associated documentation files (the\n\"Software\"), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to permit\npersons to whom the Software is furnished to do so, subject to the\nfollowing conditions:\n\nThe above copyright notice and this permission notice shall be included\nin all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS\nOR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

-     * Creates a `lodash` object which wraps `value` to enable implicit chaining.
-     * Methods that operate on and return arrays, collections, and functions can
-     * be chained together. Methods that retrieve a single value or may return a
-     * primitive value will automatically end the chain returning the unwrapped
-     * value. Explicit chaining may be enabled using `_.chain`. The execution of
-     * chained methods is lazy, that is, execution is deferred until `_#value`
-     * is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
-     * fusion is an optimization strategy which merge iteratee calls; this can help
-     * to avoid the creation of intermediate data structures and greatly reduce the
-     * number of iteratee executions.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *
-     * In addition to lodash methods, wrappers have `Array` and `String` methods.
-     *
-     * The wrapper `Array` methods are:
-     * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`,

-     * The wrapper `String` methods are:

-     * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
-     * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
-     * and `where`
-     *
-     * The chainable wrapper methods are:
-     * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
-     * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,

-     * `defer`, `delay`, `difference`, `drop`, `dropRight`, `dropRightWhile`,
-     * `dropWhile`, `fill`, `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`,
-     * `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
-     * `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *

-     * in "interpolate" delimiters, HTML-escape interpolated data properties in
-     * "escape" delimiters, and execute JavaScript in "evaluate" delimiters. Data
-     * properties may be accessed as free variables in the template. If a setting
-     * object is given, it takes precedence over `_.templateSettings` values.
-     *
-     * **Note:** In the development build `_.template` utilizes
-     * [sourceURLs](http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/#toc-sourceurl)
-     * for easier debugging.

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array of at least `200` elements
+     * and any iteratees accept only one argument. The heuristic for whether a
+     * section qualifies for shortcut fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.
+     *
+     * In addition to lodash methods, wrappers have `Array` and `String` methods.

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

+     * Creates a debounced function that delays invoking `func` until after `wait`
+     * milliseconds have elapsed since the last time the debounced function was
+     * invoked. The debounced function comes with a `cancel` method to cancel
+     * delayed `func` invocations and a `flush` method to immediately invoke them.
+     * Provide `options` to indicate whether `func` should be invoked on the
+     * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
+     * with the last arguments provided to the debounced function. Subsequent
+     * calls to the debounced function return the result of the last `func`
+     * invocation.
+     *
+     * **Note:** If `leading` and `trailing` options are `true`, `func` is
+     * invoked on the trailing edge of the timeout only if the debounced function
+     * is invoked more than once during the `wait` timeout.
+     *
+     * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
+     * until to the next tick, similar to `setTimeout` with a timeout of `0`.
+     *
+     * See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
+     * for details over the differences between `_.debounce` and `_.throttle`.

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

-     * Creates a `lodash` object which wraps `value` to enable implicit method

-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.

-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array of at least `200` elements
+     * and any iteratees accept only one argument. The heuristic for whether a
+     * section qualifies for shortcut fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.

+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

 ## Compressed vs Uncompressed
-It's important to note that there are two possible ways to represent a public key. The standard is _compressed_ and includes the X value and parity (as represented above in the documentation). There is also a longer version that is _uncompressed_ which includes both X and Y values. Using this encoding will generate a different bitcoin address, so be careful when selecting the encoding. Uncompressed public keys start with 0x04; compressed public keys begin with 0x03 or 0x02 depending on whether they're greater or less than the midpoint of the curve. These prefix bytes are all used in official secp256k1 documentation.

 ## Script Interpreting and Validation
-To validate a transaction, the bitcoin network validates all of its inputs and outputs. To validate an input, the input's script is concatenated with the referenced output script, and the result is executed. If at the end of execution the stack contains a 'true' value, then the transaction is valid. You can do this in `bitcore` by using the `Interpreter` class. The entry point (and probably the only interface you'll need for most applications) is the method `Interpreter#verify()`.

+Dashcore provides a very simple API for creating transactions. We expect this API to be accessible for developers without knowing the working internals of dash in deep detail. What follows is a small introduction to transactions with some basic knowledge required to use this API.
 
 A Transaction contains a set of inputs and a set of outputs. Each input contains a reference to another transaction's output, and a signature that allows the value referenced in that output to be used in this transaction.
 
-Note also that an output can be used only once. That's why there's a concept of "change address" in the bitcoin ecosystem: if an output of 10 BTC is available for me to spend, but I only need to transmit 1 BTC, I'll create a transaction with two outputs, one with 1 BTC that I want to spend, and the other with 9 BTC to a change address, so I can spend this 9 BTC with another private key that I own.

 So, in order to transmit a valid transaction, you must know what other transactions on the network store outputs that have not been spent and that are available for you to spend (meaning that you have the set of keys that can validate you own those funds).

-# Browser Builds
-Bitcore and most official submodules work in the browser, thanks to [browserify](http://browserify.org/) (some modules are not fully compatible with web browsers).
-
-The easiest and recommended way to use them, is via [Bower](http://bower.io/), a browser package manager, and get the release bundles. For example, when building an app that uses `bitcore` and `bitcore-mnemonic`, you do:
-
-```sh
-bower install bitcore-lib
-bower install bitcore-mnemonic
-```
-
-You can also use a `bower.json` file to store the dependencies of your project:
-
-```json
-{
-  "name": "Your app name",
-  "version": "0.0.1",
-  "license": "MIT",
-  "dependencies": {
-    "bitcore-lib": "^0.13.7",
-    "bitcore-mnemonic": "^1.0.1"
-  }
-}
-```
-
-and run `bower install` to install the dependencies.
-
-After this, you can include the bundled release versions in your HTML file:
-
-```html
-<!DOCTYPE html>
-<html lang="en">
-
-<head>
-  <meta charset="utf-8">
-  <script src="bower_components/bitcore/bitcore-lib.min.js"></script>
-  <script src="bower_components/bitcore-mnemonic/bitcore-mnemonic.min.js"></script>
-</head>
-
-<body>
-
-  <script type="text/javascript">
-    var bitcore = require('bitcore-lib');
-    var Mnemonic = require('bitcore-mnemonic');
-    // etc...
-  </script>
-
-</body>
-
-</html>
-```
-
-## Building Custom Bundles
-If you want to use a specific version of a module, instead of a release version (not recommended), you must run browserify yourself.  You can get a minified browser bundle by running the following on the project root folder.
-
-```sh
-browserify --require ./index.js:bitcore-lib | uglifyjs > bitcore-lib.min.js
-```
-
-```sh
-browserify --require ./index.js:bitcore-mnemonic --external bitcore-lib | uglifyjs > bitcore-mnemonic.min.js
-```
-
-In many of the modules you can also run the command to build a browser bundle:
-```sh
-gulp browser

-# Bitcore v0.15
-
-## Principles
-
-Bitcoin is a powerful new peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Bitcoin network allows for highly resilient bitcoin infrastructure, and the developer community needs reliable, open-source tools to implement bitcoin apps and services. Bitcore provides a reliable API for JavaScript apps that need to interface with Bitcoin.
-
-To get started, just `npm install bitcore` or `bower install bitcore`.

Locktime allows signers to create time-locked transactions which will only become valid in the future, giving the signers a chance to change their minds.

 ### Pay to Script Hash (p2sh)
-Pay to script hash outputs are scripts that contain the hash of another script, called `redeemScript`. To spend dashes sent in a p2sh output, the spending transaction must provide a script matching the script hash and data which makes the script evaluate to true.  This allows to defer revealing the spending conditions to the moment of spending. It also makes it possible for the receiver to set the conditions to spend those dashes.

-It's important to note that there are two possible ways to represent a public key. The standard is _compressed_ and includes the X value and parity (as represented above in the documentation). There is also a longer version that is _uncompressed_ which includes both X and Y values. Using this encoding will generate a different dash address, so be careful when selecting the encoding. Uncompressed public keys start with 0x04; compressed public keys begin with 0x03 or 0x02 depending on whether they're greater or less than the midpoint of the curve. These prefix bytes are all used in official secp256k1 documentation.

There is also a longer version that is _uncompressed_ which includes both X and Y values. Using this encoding will generate a different Dash address, so be careful when selecting the encoding. Uncompressed public keys start with 0x04; compressed public keys begin with 0x03 or 0x02 depending on whether they're greater or less than the midpoint of the curve. These prefix bytes are all used in official secp256k1 documentation.

 ## Script Interpreting and Validation
-To validate a transaction, the dash network validates all of its inputs and outputs. To validate an input, the input's script is concatenated with the referenced output script, and the result is executed. If at the end of execution the stack contains a 'true' value, then the transaction is valid. You can do this in `dashcore` by using the `Interpreter` class. The entry point (and probably the only interface you'll need for most applications) is the method `Interpreter#verify()`.

+Dashcore provides a very simple API for creating transactions. We expect this API to be accessible for developers without knowing the working internals of Dash in deep detail. What follows is a small introduction to transactions with some basic knowledge required to use this API.
 
 A Transaction contains a set of inputs and a set of outputs. Each input contains a reference to another transaction's output, and a signature that allows the value referenced in that output to be used in this transaction.
 
-Note also that an output can be used only once. That's why there's a concept of "change address" in the dash ecosystem: if an output of 10 DASH is available for me to spend, but I only need to transmit 1 DASH, I'll create a transaction with two outputs, one with 1 DASH that I want to spend, and the other with 9 DASH to a change address, so I can spend this 9 DASH with another private key that I own.

 So, in order to transmit a valid transaction, you must know what other transactions on the network store outputs that have not been spent and that are available for you to spend (meaning that you have the set of keys that can validate you own those funds). The unspent outputs are usually referred to as "utxo"s.

-All dash transactions contain a locktime field. The locktime indicates the earliest time a transaction can be added to the blockchain. Locktime allows signers to create time-locked transactions which will only become valid in the future, giving the signers a chance to change their minds. Locktime can be set in the form of a dash block height (the transaction can only be included in a block with a higher height than specified) or a linux timestamp (transaction can only be confirmed after that time).

+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be

+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array of at least `200` elements
+     * and any iteratees accept only one argument. The heuristic for whether a
+     * section qualifies for shortcut fusion is subject to change.

+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

- * Instantiate an address from an address String or Buffer, a public key or script hash Buffer,
- * or an instance of {@link PublicKey} or {@link Script}.
- *
- * This is an immutable class, and if the first parameter provided to this constructor is an
- * `Address` instance, the same argument will be returned.
- *
- * An address has two key properties: `network` and `type`. The type is either
- * `Address.PayToPublicKeyHash` (value is the `'pubkeyhash'` string)
- * or `Address.PayToScriptHash` (the string `'scripthash'`). The network is an instance of {@link Network}.
- * You can quickly check whether an address is of a given kind by using the methods
- * `isPayToPublicKeyHash` and `isPayToScriptHash`
- *
- * @example
- * ```javascript
- * // validate that an input field is valid
- * var error = Address.getValidationError(input, 'testnet');
- * if (!error) {
- *   var address = Address(input, 'testnet');
- * } else {
- *   // invalid network or checksum (typo?)
- *   var message = error.messsage;
- * }
- *
- * // get an address from a public key
- * var address = Address(publicKey, 'testnet').toString();
- * ```
- *
- * @param {*} data - The encoded data in various formats
- * @param {Network|String|number=} network - The network: 'livenet' or 'testnet'
- * @param {string=} type - The type of address: 'script' or 'pubkey'
- * @returns {Address} A new valid and frozen instance of an Address
- * @constructor

- * Utility for handling and converting bitcoins units. The supported units are

- * You can consult for different representation of a unit instance using it's

- * the unit accessors. It also can be converted to a fiat amount by providing the
- * corresponding BTC/fiat exchange rate.

- * @example
- * ```javascript
- * var sats = Unit.fromBTC(1.3).toSatoshis();
- * var mili = Unit.fromBits(1.3).to(Unit.mBTC);
- * var bits = Unit.fromFiat(1.3, 350).bits;

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *
-     * In addition to lodash methods, wrappers have `Array` and `String` methods.
-     *
-     * The wrapper `Array` methods are:
-     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
-     *
-     * The wrapper `String` methods are:
-     * `replace` and `split`
-     *
-     * The wrapper methods that support shortcut fusion are:
-     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
-     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-     *
-     * The chainable wrapper methods are:
-     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
-     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

 There was a bug that was discovered with derivation that would incorrectly calculate the child key against the [BIP32 specification](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki).
-The bug only affected hardened derivations using an extended private key, and did not affect public key derivation. It also did not affect every derivation and would happen 1 in 256 times where where the private key for the extended private key had a leading zero *(e.g. any private key less than or equal to '0fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff')*. The leading zero was not included in serialization before hashing to derive a child key, as it should have been.

 As a result, `HDPublicKey.derive()` and `HDPrivateKey.derive()` are now deprecated. These methods will throw an error in the next major release.
 `HDPublicKey.deriveChild()`, `HDPrivateKey.deriveChild()`, and `HDPrivateKey.deriveNonCompliantChild()` have been implemented as alternatives. Note that these new methods will not be officially supported until v1.0.0.  `deriveNonCompliantChild` will derive using the non-BIP32 derivation and is equivalent to the buggy version, `derive`. The `deriveNonCompliantChild` method should not be used unless you're upgrading and need to maintain compatibility with the old derivation.

 ## Script Interpreting and Validation
-To validate a transaction, the Dash network validates all of its inputs and outputs.

-All Dash transactions contain a locktime field. The locktime indicates the earliest time a transaction can be added to the blockchain.

-## Principles
-
-Dash is a powerful new peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Dash network allows for highly resilient Dash infrastructure, and the developer community needs reliable, open-source tools to implement Dash apps and services.
+### THIS LIBRARY IS A WORK-IN-PROGRESS
 
 ## Get Started
 ### NodeJS
 ```
-npm install @dashevo/dashcore-lib
+npm install @anonymousbitcoin/anoncore-lib

-     * is implicitly or explicitly called.

-     * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
-     * fusion is an optimization strategy which merge iteratee calls; this can help

+# Governance Object
+A Governance Object (or "govObject") is a generic structure introduced in Dash Core v12.1 to allow for the creation of Budget Proposals, Triggers, and Watch Dogs. Class inheritance has been utilized to extend this generic object into a "Proposal" which is outlined throughout the remainder of this document. 
+
+### `new GovObject([govObjectData])`
+
+Creates a new `GovObject` object where:
+  - `govObjectData` - optional data (allowed types are `json`, `jsonString`, `hex`, `buffer`, `GovObject`)
+
+### Methods
+
+####  `dataHex`  
+Returns a dataHex representation (see above)
+####  `fromObject`  
+Allow to create a govObj from a json or stringifiedJSON obj
+####  `fromString`
+Allow to create a govObj from a hex string
+####  `checkedSerialize`
+Return a hex string that can be used in dashd CLI
+####  `serialize`
+Return a hex string
+####  `inspect`
+Returns a representation of the object
+####  `toBuffer`
+Return a buffer
+####  `fromBuffer`
+Allow to create a govObject from a buffer
+####  `shallowCopy`
+Allow to shallowCopy from another govObject
+
+## Governance Object Creation
+
+The following would create a blank govObject
+
+```javascript
+// instantiate a new govObject instance
+var govObject = new GovObject();
+```
+
+Budget Proposals can be created from a valid JSON object (stringified or not)
+
+```javascript
+var jsonProposal = {
+  name:"My First GovObject",
+  start_epoch:1483228800, //timestamp in seconds
+  end_epoch:1483747200, //Is valid if end_epoch>now_epoch
+  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
+  payment_amount:10,
+  type:1,//In this case, it will cast a proposal
+  url:"http://www.dash.org/proposal/first_proposal"
+};
+
+//Will instantiate the govObject given the json passed as arg for fromObject
+govObject = govObject.fromObject(jsonProposal);
+var govObject = new GovObject().fromObject(jsonProposal);
+
+
+//It worth mentioning that fromObject can also be a valid stringified json.
+var govObject = new GovObject().fromObject(JSON.stringify(jsonProposal));
+```
+
+Budget Proposals can be instantiated from a Buffer
+
+```javascript
+//Allow to create a new object from a given buffer
+var fromBuff = new GovObject(govObjBuffer);
+//Or
+var fromBuff = new GovObject().fromBuffer(govObjBuffer);
+
+//And from an hexa string
+var fromString = new GovObject("5b5b2270726f706f736...");
+//or
+var fromString = new GovObject().fromString("5b5b2270726f706f736...")
+```
+
+You can display a hex-encoded representation of a Budget Proposal with a simple "toString()"
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+var hexString = fromString.toString();
+//or
+var hexString = fromString.serialize();
+```
+
+Logging the object will also return a hex-encoded representation of the object
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+console.log(fromString) //<GovObject: 5b5b2270726f706f7...>
+//Or using the method
+fromString.inspect();
+```
+
+You could shallowcopy a first govObj into a second one
+
+```javascript
+proposal.url="http://dash.org/badUrl"
+var shallowCopyProposal = proposal.shallowCopy();
+proposal.url="http://dash.org/fixedUrl"
+
+console.log(proposal.url!==shallowCopyProposal.url)//return true as it's a copy
+console.log(proposal!==shallowCopyProposal)//return true
+```
+
+Finally you are able to get the dataHex from the object
+
+```javascript
+var fromString = new GovObject("5b5b2270726f706f736...");
+
+fromString.dataHex()//Give a stringified json [['proposal',{name:"My First GovObject",....}]]
+
+//You could get back the given JSON object by doing so
+var JSONObject = JSON.parse(fromString.dataHex())[0][1]);
+```
+
+## GovObject Types:
+
+Each of these types are inherited from govObject allowing the same methods to be callable.
+
+* Proposal `type:1`: Allow to create a proposal which inherit govObject method and overwrite them when needed
+
+```javascript
+var jsonProposal = {
+  name:"My First Proposal",
+  start_epoch:startDate,
+  end_epoch:endDate,
+  payment_address:'yXGeNPQXYFXhLAN1ZKrAjxzzBnZ2JZNKnh',
+  payment_amount:10,
+  type:1,
+  url:"http://www.dash.org"
+};
+
+var proposal = new Proposal();
+// create a new proposal from a stringified JSON object
+proposal = proposal.fromObject(JSON.stringify(jsonProposal));
+
+var shallowCopy = proposal.shallowCopy(); //As proposal inherits govObject
+
+//Return a hex equivalent of the proposal
+var hexProposal = proposal.serialize()
+```
