The blob store dat uses per default
npm install dat-blob-store
var store = require('dat-blob-store')
var blobs = store('./some-folder')
var ws = blobs.createWriteStream('test.txt')
ws.write('hello world\n')
ws.end(function () {
console.log(ws.key) // use this key (a hash) to read out the blob
})
The blob store will store two copies of the file written. One in test.txt and one
content-addressed in data.dat/blobs.
