Blockstore enables human-readable name registrations on the Bitcoin blockchain, along with the ability to store associated data in external datastores. You can use it to register globally unique names, associate data with those names, and transfer them between Bitcoin addresses. Anyone can perform lookups on those names and securely obtain the data associated with them.

Blockstore uses the Bitcoin blockchain for storing name operations and data hashes, and the Kademlia-based distributed hash table (DHT) and other external datastores for storing the full data files outside of the blockchain.

NOTE: This repo is going through rapid development. If you notice any issues during installation etc please report them in Github issues. We hope to have a stable, easy to install, version out very soon!

This document is meant to provide an overview of how to get blockstore up and running on Mac OS X, Linux, and other UNIX-like operating systems. It is meant to be a high-level walk-through for application developers who want to run their own Blockstore instance. Basic proficiency with the command-line is required.

The fastest way to get started with blockstore is to use pip:

pip install blockstore

If you encounter any problems during the pip install, see the detailed install instructions.

Start blockstored and index the blockchain:

$ blockstored start

Then, perform name lookups:

$ blockstore-cli lookup werner.id
{
    "address": "1KRca8gGiCiTNGR65iXMPQ6d5fisDdN3ZF",
    "first_registered": 374132,
    "last_renewed": 374132,
    "revoked": false,
    "sender": "76a914ca19f0c96683b6cabfb5c9a406bebc6771d8ede488ac",
    "sender_pubkey": "0411d88aa37a0eea476a5b63ca4b1cd392ded830865...",
    "value_hash": "3dafd5f42798df3045cd2eb70a71cccf8500e6d4"
}

Next, learn how to register names of your own, as well as transfer them and associate data with them:
