The o1Labs team is proud to announce that 3.1.0-beta1 is ready to test on Mainnet! This release includes some 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-beta1 in the name of any issues you create. Please report any issues you encounter here or join the discussion!

Upgrading & Connecting to Mainnet

Debian Packages:

Debian Repository: First, set up and update the beta Debian Repository for your platform with the following commands:

sudo rm /etc/apt/sources.list.d/mina*.list
echo "deb [trusted=yes] http://packages.o1test.net $(lsb_release -cs) beta" | sudo tee /etc/apt/sources.list.d/mina-beta.list
sudo apt-get update

Then, install the package(s) that you need:

Mina Daemon: sudo apt-get install --allow-downgrades -y mina-mainnet=3.1.0-beta1-a35e440
Mina Archive: sudo apt-get install --allow-downgrades -y mina-archive=3.1.0-beta1-a35e440
Mina Archive Schema: create_schema.sql
Config File: var/lib/coda/config_a35e4407.json

Docker Images:

Every docker image is built for each of the supported platforms, replace CODENAME in the images below with your choice of focal or bullseye to select the base docker image.

Mina Daemon: gcr.io/o1labs-192920/mina-daemon:3.1.0-beta1-a35e440-CODENAME-mainnet
Mina Archive: gcr.io/o1labs-192920/mina-archive:3.1.0-beta1-a35e440-CODENAME

Step by Step Guide:

Docker only Make sure to run with:

--peer-list-url https://storage.googleapis.com/mina-seed-lists/mainnet_seeds.txt or add PEER_LIST_URL=https://storage.googleapis.com/mina-seed-lists/mainnet_seeds.txt to your .mina-env.

Run mina daemon with:

mina daemon --peer-list-url https://storage.googleapis.com/mina-seed-lists/mainnet_seeds.txt

Check out our documentation for complete instructions on using this version to connect to Mainnet.

If you are running the correct version on the correct network MAINNET, mina client status will show:
