IPFS Block Service

standard-readme compliant Travis CI Dependency Status js-standard-style

IPFS implementation of the BlockService and Block data structure in JavaScript.

BlockService - A BlockService is a content-addressable store for blocks, providing an API for adding, deleting, and retrieving blocks. A BlockService is backed by an IPFS Repo as its datastore for blocks, and uses Bitswap to fetch blocks from the network.
