I'm trying to use ZeroMQ integration feature from bitcoind.

According to docs it supports four topic:

  • hashtx
  • hashblock
  • rawblock
  • rawtx

Sadly, they are not very well documented.

So, what is the difference between raw/hash topics?

After some investigation, I found out that RAW topics actually include entire body of transaction/block descriptor.

See, Raw Transactions.

Actually, you could explore the transaction descriptor content in JSON format by first converting binary data to HEX-string and then by pasting it to the blockchain.info tool or by using RPC call of bitcoind: decoderawtransaction.
