Bitlab Bitcoind Clustering

[Bitlab]

Using Firebase and NodeJS we have created a clustering solution for bitcoind that allows you to use several bitcoind servers to serve a single system.

https://github.com/bitlabco/bitlab-nodejs

It consists of three nodes:

1. Address Node - listens for new address requests and generates a new address from a randomly selected bitcoind.

2. Receive Node - listens for new payments from each bitcoind, updates the account balance and generates a transaction record.

3. Send Node - listens for new withdrawal requests and sends the bitcoins from the first available bitcoind with sufficient balance.

are the private keys stored locally on each node? ie, if one node is compromised does the amount on bitcoin on the entire cluster get lost? or does 1/x (if btc is spread evenly between nodes). Or optimally are the keys generated so each node only has 1/x of the key. So an attacker would need to compromise all the servers to get the full private key?

Thanks for your question.

Each server is just a standard bitcoind server. If one of the servers gets hacked, you lose the coins on that particular server.
