Block Explorer Support

  • Status: almost completed

Tracking: Zaino Continuation · GitHub

After some research and development work Zaino folks and myself decided that 1.6: Add Zcash RPC getblockhashes is not a strong candidate for implementation any longer. The team will pivot to other work since this RPC is really time consuming and not used by any other than nighthawk explorer which the community is moving away from anyway. This means that the bulk of the work is almost completed.

Done

Thanks for reading!
