Cronos EVM “Pallene” Upgrade - Announcing Upgrade Block Height: 17,155,000
The upcoming Cronos Mainnet Pallene upgrade introduces parallel transaction processing and multiple upgrades leveraging the latest Cosmos SDK and CometBFT.
Following our announcement of the Cronos Mainnet V1.4 upgrade, we are pleased to announce more upgrade details:
The Cronos Mainnet Pallene upgrade block height is set to 17,155,000, expected around Thursday, 12nd Dec, 2024 at 6AM GMT (2PM HKT/SGT), depending on the progress of block production. Check here for the estimated time;
The network downtime is anticipated to be about 60 mins, depending on the progress of the validator’s upgrade;
All Cronos services, such as Cronos mainnet network, public RPCs, Explorer, and Cronos bridge, will be paused and resumed after the upgrade is completed.
What to Expect for End-users
The proposed upgrade date is Thursday, 12nd Dec, 2024, and the chain will be upgraded at a specific block height of 17,155,000; the estimated time of this block can be found here.
After the upgrade block height, all node operators will upgrade their node binary to maintain sync with the chain. The chain will temporarily pause and then resume, with all the data persisted, once the majority of validators have completed their upgrades.
Actions Required for Node Operators
The Cronos chain will be upgraded at the block height of 17,155,000. Once we reach the upgrade block height, all node operators must follow the instructions and upgrade to the latest cronosd binary - “v1.4.1” to keep the nodes in sync with the chain.
Please DO NOT UPGRADE to the binary v1.4.0 before the target upgrade block, as it will be incompatible.
