Devnet Pre-Release 3.1.0-alpha1

on GitHub

The o1Labs team is proud to announce that 3.1.0-alpha1 is ready to test on Devnet! This release includes some new features, bug fixes, hashing performance enhancements as well as additional code cleanup & general improvements. A very cool addition to this release is an optimization to the ledger synchronization protocol, specifically enhancing how nodes sync their ledger state during a fresh startup, after downtime, or restarting from stale state.

The change reduces the number of network roundtrips needed to sync a ledger and therefore makes syncing fast even as the # of accounts in the ledger grows!

We have also introduced enhancements during bootstrapping to reduce empty blocks on node restart.

We have also landed some very cool additional work such as a reduction of the max time to produce a block from >120s down to <45s and some nice items that allow for resource reductions.

This release also introduces the ability to spin up custom snark coordinator configurations! Here's a cool script that showcases the usage!

If you run into any issues, please include Release: 3.1.0-alpha1 in the name of any issues you create. Please report any issues you encounter here or join the discussion!
