p2p alternatives

[Oscar Guindzberg]

Hi,

Are there examples of using bitcoinj's wallet and blockchain without
using bitcoin p2p to get blockchain data?

E.g. using bitcoin core rpc interface (
https://github.com/johannbarbie/BitcoindClient4J) or a block explorer
API to get blockchain data.

I am trying to find ways to integrate electrumJ with bitcoinj.

Thanks.

You can use the ConsensusJ RPC client which conveniently uses bitcoinj types (where possible) for parameters and return values:

https://github.com/ConsensusJ/consensusj/

Gradle setup:

repositories {

maven {

url  "https://dl.bintray.com/msgilligan/maven"

}

}

dependencies {

    implementation 'com.msgilligan:cj-btc-jsonrpc:0.5.4'

}

Example code:

var client = new BitcoinClient(MainNetParams.get(), RpcURI.defaultMainNetURI, rpcTestUser, rpcTestPassword);

Sha256Hash hash = getBlockHash(324140);
Block block = getBlock(hash);

You probably can't use WalletKit or any of the blockchain implementations, but you could probably use one of the Key Chain classes.
