Cronos Network Upgrades for Seamless DApp Integration

Cronos, a network compatible with Cosmos EVM, completes its mainnet v1.2 upgrade aimed at enhancing developer experience for integration.

Network compatible with Cosmos EVM Cronos reported the successful completion of its mainnet v1.2 upgrade with all services back up. This update’s main goal is to make it easier for developers to integrate and run decentralized apps (DApps) on the platform by improving backward compatibility.

Cronoscan, their other blockchain explorer, is currently catching up and completing its functionalities, while the Chain Explorer is currently up and running.

Deployed at block height 13520000, the most recent version of their mainnet enhances RPC capabilities and backward compatibility.

Its contracts will use either block.prevrandao or block.difficulty to maintain the backward compatibility of dApps. This update ensures that the opcode associated with block.difficulty and/or block.prevrandao in Cronos yields a constant value. This change tries to fix the behavior of older smart contracts without influencing the behavior of new ones.

The RPC upgrade also fixes an RPC problem and adds support for new EVM types and parameters. As part of this issue repair, we added a parameter key table to the Ethereum Virtual Machine (EVM) for earlier upgrades. With the v1.2 update, they have enabled RPC querying for blocks created in previous versions.

Cronos Completes Titan Upgrade to Meet Ethereum Compatibility Roadmap

Cronos is an EVM-compatible network that operates on the Cosmos EVM SDK framework and utilizes Ethermint. This configuration enables the quick migration of smart contracts and apps from Ethereum and other EVM-compatible blockchains to Cronos. It uses the coin CRO to pay transaction fees. The network employs a Proof-of-Authority (POA) consensus process, drawing inspiration from the Tendermint POS consensus.

In an effort to comply with its roadmap for Ethereum interoperability, they recently finished the Titan Upgrade for its mainnet, integrating Ethereum’s “Shanghai.” This update significantly modified certain smart contracts running on Cosmo EVM, particularly those that relied on block.difficulty and/or block.prevrandao expressions.
