Cronos has successfully upgraded its mainnet to version 1.2 to significantly improve backward compatibility for developers.
In Brief
The Cronos network proudly confirms that their v1.2 mainnet upgrade has been completed successfully, with all services restored to functionality.
Cosmos EVM-compatible network Cronos The primary goal of this upgrade is to enhance backward compatibility for developers, facilitating smoother integration and enhanced performance for decentralized applications (DApps) operating on the network.
Currently, the Cronos Chain Explorer is functioning well, while Cronoscan, another blockchain explorer, is working towards full operational capacity.
The recent update to the Cronos mainnet, initiated at block height 13520000, not only boosts backward compatibility but also improves RPC functionality across the board.
To maintain backward compatibility for decentralized applications, the system now uses either block.prevrandao or block.difficulty in its contracts. With this update, Cronos will consistently return a standard value to the opcode linked to block.difficulty and/or block.prevrandao, ensuring that older smart contracts function as intended without disrupting new developments.
Moreover, the RPC enhancements include support for additional EVM parameter types and fixes for existing RPC issues. This update introduces a key parameter table for the Ethereum Virtual Machine (EVM) from prior upgrades, allowing RPC queries for blocks created in earlier versions post the v1.2 upgrade.
Cronos has completed the Titan Upgrade to better align with Ethereum's compatibility roadmap.
Cronos As a network built on the Cosmos SDK and utilizing Ethermint, Cronos functions as an EVM-compatible platform, allowing for quick migrations of applications and smart contracts from EVM-compatible blockchain environments like Ethereum. Users can pay transaction fees on the Cronos network using CRO cryptocurrency Employing a Proof-of-Authority (POA) consensus mechanism derived from the Tendermint POS consensus, Cronos operates efficiently.
The recent Titan Upgrade for the Cronos mainnet incorporated Ethereum's 'Shanghai' upgrade, aiming to foster greater compatibility with its developmental roadmap. Ethereum This update has introduced major adjustments for specific smart contracts on Cronos, particularly those that depend on parameters such as block.difficulty or block.prevrandao.
