New Alpha Release: Optimization and Non-malleability

Simon Liu | Aug 06, 2016

Today, we deployed a new alpha release of the Zcash reference implementation, v0.11.2.z8, to the testnet. The new release includes the following changes [1]:

  1. Equihash mining parameters have been adjusted to n=200, k=9 to reduce average solution search time to <45 seconds, and average time-to-first-solution to <30 seconds. (#856)
  2. The Equihash miner will now interrupt and cancel an existing solution search when a new valid block arrives. (#1055)
  3. The Equihash miner will now check solutions as soon as they are found. (#1143)
  4. Transaction malleability has been fixed so that valid transactions can not be modified in-flight. (#1144)
  5. The SIGHASH_SINGLE bug has been fixed. (#1078)
  6. Compilation flags have been updated to harden security. (#1064)

The zcraw* RPC commands are still available for use but will be deprecated in a future release.

This alpha release will reset our testnet, invalidating all previous coins and breaking backwards compatibility. To get connected to the new testnet, follow the instructions on the Public Alpha Guide.
