HashGG v0.7.2.2 Released, plus Companion

Bitcoin
1

HashGG v0.7.2.2 adds support for Retropex’s Datum Gateway for the new BLAKE2b chain. You can now use HashGG to easily connect rented hash rate to your server for either chain.

This release also comes with a “Companion” version, which integrates with my pruned companion stack:

  • Bitcoin Knots (BLAKE2b) Companion
  • Datum Gateway (BLAKE2b) Companion
  • Mempool Pruned
  • Electrs Pruned
  • Sparrow (BLAKE2b)

This enables anyone who wants to run a second (pruned) node on the same server without needing to break the bank on NVMe storage space. With HashGG Companion, you can mine on both chains from a single server (Start9 and Umbrel supported).

Appreciate your work Paul! Does the Sparrow (BLAKE2b) implementation include any replay protection?

No, I’m treating that as a separate function outside of the wallet (to avoid requiring connections with two nodes, which could be confusing).

I suppose I could work in an automatic step that hits the sighash fix, though, now that I think about it. I’ll look into that option.

That’s the method used here (I think): Releases · privkeyio/shrike · GitHub
