github-actions released this 2 hours ago
This release is an important update to the node that provides the functionality that is needed following the Alonzo hard fork.
All users, including stake pool operators, must upgrade to this version (or a later version) of the node.
The release includes features that will enable the use of the node in the Alonzo era, allowing the on-chain execution of Plutus scripts,
including extended CLI commands to support the construction of transactions that include Plutus scripts, datums and redeemers.
It incorporates several improvements, including a new transaction build command that calculates transaction fees and Plutus script execution units, and a new version of the query tip command that provides additional information, including node synchronisation progress. The transaction build command requires a local instance of the node in order to check Plutus script validity and to provide information that is used by the fee calculation. The Shelley specification has also been updated with respect to rewards calculation.
Note that this release changes the log format of traces configured by TraceChainSyncHeaderServer and TraceChainSyncClient . See #2746 for more detail.
When migrating to 1.29.0, SPOs need to make the following changes:
- Download
mainnet-alonzo-genesis.jsonfile - Update
mainnet-config.jsonfile to include the following 2 lines:
"AlonzoGenesisFile": "mainnet-alonzo-genesis.json",
"AlonzoGenesisHash": "7e94a15f55d1e82d10f09203fa1d40f8eede58fd8066542cf6566008068ed874",
How to update to 1.29.0
!!! YOU MUST KNOW THAT 1.29.0 version will use ~8,1G RAM !!!
bofore to start it’s better also to update the server
sudo apt-get update
sudo apt-get upgrade
sudo reboot
- perform a snapshot for server (if u have this option offered by your provider) before to start the update
- update the Relays first (one by one)
BUILDING THE NODE
- stop the node :
sudo systemctl stop cnode
- build the node
cd ~/git
sudo rm -R cardano-node
git clone https://github.com/input-output-hk/cardano-node
cd cardano-node
git fetch --tags --all
git checkout 1.29.0
echo -e "package cardano-crypto-praos\n flags: -external-libsodium-vrf" > cabal.project.local
$CNODE_HOME/scripts/cabal-build-all.sh
Download the mainnet-alonzo-genesis.json file and modify the config.json file
I saw that the prereqs.sh script was not updated for alonzo-genesis file so, we will need to download it manually;
Download the mainnet-alonzo-genesis.json file (for cntools I renamed the file to alonzo-genesis.json only and also the name should match with the filename from config.json file)
cd $CNODE_HOME/files or cd /opt/cardano/cnode/files
curl -sL -f -o alonzo-genesis.json https://hydra.iohk.io/job/Cardano/iohk-nix/cardano-deployment/latest-finished/download/1/mainnet-alonzo-genesis.json
chmod 755 alonzo-genesis.json
ls -l
Modify the config.json file
nano config.json
add the 2 lines inside the file (I added on top)
"AlonzoGenesisFile": "/opt/cardano/cnode/files/alonzo-genesis.json",
"AlonzoGenesisHash": "7e94a15f55d1e82d10f09203fa1d40f8eede58fd8066542cf6566008068ed874",
save the file
