How to run (2 options)

1. modify execution configuration and enter PID 0 | 1 | 2 as CLI argument and run Blockchain.main()

   1. [OPTIONAL] Give respective execution configuration a name/id for clarity Blockchain 0 | Blockchain 1 | Blockchain 2
   2. run each config file starting from 0

2. In root directory, run docker compose up -d from command line

   1. when shut down initiates, inspect shut down snapshot with docker compose logs. One can also enter the container pow-process0 and inspect the BlockchainLedger.json
   2. clean up -- docker compose down

verifying with JQ

• cat BlockChainLedger.json | jq '. | length' : should always be 13 blocks
  • 1 dodgy block record
  • 4 legit block record for each process (4*3=12)
• cat BlockChainLedger.json | jq : to view ledger in pretty print json
  • ensure block id is incremental
  • ensure verified blocks are not duplicated and only appear once
  • ensure winning hash continues to be used to build next block
  • ensure all processes are participating in the blockchain protocol
