As many of you are already aware, we have been working to stablize version 1.2.0 for quite some time. The O(1) Labs Team is proud to announce that 1.2.0 Stable is ready for use in production on Mainnet! 1.2.0 contains a variety of Quality of Life Improvements for node operators, including some new tools, graphql queries, cli commands, metrics, not to mention the countless efforts that went on behind the scenes to keep Mainnet and our team at O(1) Labs running smoothly.
In addition, 1.2.0 includes the client for the proposed update to the Mina Foundation Delegation Program (some further server work is required before the updated program launches, stay tuned for more announcements from the Mina Foundation on this topic). You can test the client implementation and configuration yourself as described below in the New Features section.
New Features:
GraphQL:
- Match GraphQL sync status with the daemonStatus #8255
- Allows the
pooledUserCommands query to select transactions by hash or ID, to make it more consistent with transactionStatus #8293
- Adds new GraphQL endpoint
stagedLedgerProofEmitted to indicate that a new staged ledger proof was formed #8658
CLI Commands:
- Improved handling of locally-generated transactions to allow re-sending transactions and give the user more control over rebroadcasting transactions. No more
already saw this errors! #8973
mina advanced vrf is a set of new advanced commands for generating and evaluating VRF witnesses to prove that your key has won a slot #8814mina advanced hash-transaction is a new command for hashing transactions #8294mina ledger export snarked-ledger is a new command for exporting snarked ledgers with proven balances #8844- Show the coinbase-receiver in
mina client status if it is set, and adds a new command mina advanced set-coinbase-reciever to change the coinbase receiver at runtime #8127
mina advanced chain-id-inputs is a new command for displaying the inputs to the ChainID #8264mina advanced send-rosetta-transaction now immediately sends the transaction instead of waiting for the command to exit #8186mina accounts commands now support retrieving/uploading keys and account information over a remote graphQL interface instead of just local files #7282- Return exit code 1 when
mina ledger export commands fail #8720
- New flag
--minimum-block-reward to mina daemon that allows a block producer to set the minimum net reward from producing a block. #8605
- Addresses concerns from #8576 and block producers who have overpaid for snark work. If paying the fees for a given snark would drop the resulting profit below the given value, an empty block with no transactions is produced instead.
Other:
- More coda->mina changes #8238
- Allow passing peers-list-url parameter as part of the daemon.json or other config file #8295
- Quieter logging and improved messaging during daemon startup #8261 #8203 #8146 #8260 #8488 #8503
- Improved Mina Foundation Uptime Tracking! #9499
- This feature no longer requires importing your keypair, now supports a new flag --uptime-submitter-key which takes the path to your private key, just like --block-producer-key.
- To test the new system, pass in the following information to the daemon:
- The path to the private key with the flag --uptime-submitter-key </path/to/private/key>
- The URL of our testing backend server with the flag --uptime-url http://34.134.227.208/v1/submit
- The password for the keypair associated to the given public key with the environment variable UPTIME_PRIVKEY_PASS=My_V3ry_S3cure_Password. If you are using a .mina-env file on Debian then this value should be on its own line, not included in EXTRA_FLAGS=.
- New environment variables in .mina-env for use with the mina systemd service #9375 #9533
- Passes in the --peer-list-url automatically to correspond to the mina package (mina-mainnet for mainnet peers list, and mina-devnet for devnet peers).
- This value can still be overridden with PEERS_LIST_URL variable in .mina-env
- Block production is disabled by default, use EXTRA_FLAGS as shown below to configure your block producer keys
- LOG_LEVEL variable to set the daemon log level, with the default value Info
- FILE_LOG_LEVEL variable to set the daemong file log level, with the default value Debug
- Remove --generate-genesis-proof true as it no longer does anything in this mina version
- Changed WantedBy to default.target instead of multi-user.target as the latter does not work in user services (as many users have reported)
EXTRA_FLAGS="--block-producer-key /home/mina/my-wallet --uptime-submitter-key /home/mina/my-wallet --uptime-url http://34.134.227.208/v1/submit"
UPTIME_PRIVKEY_PASS=My_V3ry_S3cure_Password
MINA_PRIVKEY_PASS=My_V3ry_S3cure_Password
CODA_PRIVKEY_PASS=My_V3ry_S3cure_Password
LOG_LEVEL=Info
FILE_LOG_LEVEL=Debug
Note: MINA_PRIVKEY_PASS will not be supported until the 1.3.0+ Mina Daemon releases but it won't hurt to start providing it now.

Upgrading & Connecting
Debian Packages:
From now on builds will be packaged and released to the debian repo based on debian release codenames (stretch for Debian 9/Ubuntu 18.04 and soon buster for Debian 10 / Ubuntu 20.04), and a release channel (alpha, beta, stable, unstable).
Repository Setup:
To allow for installation of mina stretch stable builds:
echo "deb [trusted=yes] http://packages.o1test.net stretch stable" | sudo tee /etc/apt/sources.list.d/mina.list
sudo apt-get update
Installation:
Mina Daemon:
sudo apt-get install -y mina-mainnet=1.2.0-fe51f1e
Mina Archive:
sudo apt-get install -y mina-archive=1.2.0-fe51f1e
Mina Generate Keypair:
sudo apt-get install -y mina-generate-keypair=1.2.0-fe51f1e
Archive Node Schema for initializing postgres:
create_schema.sql
Docker Images:
Mina Daemon:
minaprotocol/mina-daemon:1.2.0-fe51f1e-mainnet
Mina Archive:
minaprotocol/mina-archive:1.2.0-fe51f1e
Mina Generate Keypair:
minaprotocol/mina-generate-keypair:1.2.0-fe51f1e
Archive Node Schema for initializing postgres:
create_schema.sql
Sandbox Node: For testing in an isolated, single-node network without snarks
As of 1.2.0, the demo functionality is built into the standard daemon container, via the environment variable RUN_DEMO=true.
Just docker run -it --name mina-demo -e RUN_DEMO=true minaprotocol/mina-daemon:1.2.0-fe51f1e-devnet and go!
NEW Devnet:
This release is the first to support the newly relaunched Devnet. To use any of the above packages or docker images with devnet instead of mainnet, you can simply replace mainnet with devnet in either the name of the package or the docker image tag.
Block Producer Stats Sidecar:
The block producer sidecar will be replaced with the foundation delegation uptime tracker described above, once the backend verification system is ready. In the meantime any version of the sidecar since ~1.1.6 should work the same way, and the data produced by the sidecar still counts towards foundation delegation elegibility. Stay tuned on Discord for further announcements from Mina Foundation in regards to the Delegation Program.
Questions and Feedback
If you discover any issues or regressions from 1.1.8, please report them so we can look into it. Please include the mina version output or 1.2.0 in the issue title/description so we can more easily sort through the issues.
For questions and feedback, please go to the #mainnet-block-producers channel on our Discord or comment on the Github Discussion for this release, we're excited to hear about your experience with this new build!
Step by Step Guide:
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, mina client status will show:
