Using Bloom filter to verify balance

[rllola]

Hello,

I would like to use webcoin and more particularly the Bloom filter. I am having a hard time to understand how it works. So simple use case : I would like to verify how much there is on a address. How can I do this, do I still need to sync all the headers ?

Thanks,

Yes, you will need to sync all the headers after adding your data (the
public key hash associated with your addresses) to the Bloom filter. If you
know that your key was generated at a certain time, you only need to sync
starting at when they key was made, since you know there won't be any
transactions before that.

I'll build a simple module for this and put it on npm when I get some time. I'll try to make the API look something like this:

let scanner = scan({
    address: 'some address',
    dateCreated: 1484180397934, // some date
    node: node
})
scanner.on('balance', function (e) {
    console.log('balance changed:', e.balance)
})
