Goal: Take block hash as input and get all the block information represented on a UI.

How to use

Download bitcoin core https://bitcoin.org/en/full-node

modify your bitcoin.conf Example:

server=1
dbcache=1536
par=1
maxuploadtarget=137
maxconnections=16
rpcuser=ozioma
rpcpassword=password
rpcallowip=127.0.0.1
debug=tor
prune=550
mintxfee=0.001
txconfirmtarget=1
[test]
rpcbind=127.0.0.1
rpcport=18332
[main]
rpcbind=127.0.0.1
rpcport=8332
[regtest]
rpcbind=127.0.0.1
rpcport=18443

Install bitcoin-cli and Run bitcoin core as a daemon process See https://bitcoin.org/en/full-node#other-linux-daemon

Clone project and from the project root folder run gradle assemble, From the project root folder run

gradlew assemble

if permission is denied, run chmod 755 gradlew first before gradlew assemble

this would build a .jar file that in the build folder that you can then run using

java -jar /build/libs/com.ozioma.bitcoinexplorer-all.jar

goto: http://127.0.0.1:8080/block/full/{block_hash}/ to view the information about a block.

Http calls are made to the bitcoin node using https://ktor.io

Block information is rendered using FreeMarker https://ktor.io/docs/freemarker.html

This project is for experimenting and learning how to use the block chain, not for production.
