- The block size limit has been increased to 2MB. (#765) We’re tracking the worst-case verification costs in some new performance measurements and in #1077 in order to mitigate potential DoS attacks.
- Equihash nonces are now randomized to avoid duplicate effort by miners. (#1060)
- Equihash solving runs are now slightly more efficient. See #1049 and the change in performance measurements on our tracker.
Last night the Zcash team released an update to the Test Network. As I mentioned in this post Instead of a complete reset of the network which normally wipes all test coins the Zcash developers have natively implemented a Hard Fork increasing the block size to 2MB. This new release (z6) also implements a much needed Equihash optimization that randomizes the nonce values to prevent a miner with multiple threads running from duplicating it’s own work. You will have to download the latest version z6 to connect to the updated network. I have also just updated the Tutorial to reflect this update. This is first time the Zcash code will be tested with a hard fork so it will be interesting to see the impact on the test network and the miners.
