The Core mainnet is expected to have a scheduled hardfork upgrade, Fusion Upgrade, on 19th Nov. 2024 around 07:00 AM (UTC). This upgrade unlocks better Bitcoin staking options and enhanced scalability and performance for the Core blockchain. The validators and full node operators on the Core mainnet must switch their software version to v1.0.12 before 18th Nov. 2024.
A hardfork is a significant upgrade that introduces breaking changes that are incompatible with previous network versions. These changes are essential for enhancing the network’s functionality and security. If existing validators or full-node operators do not upgrade their nodes on time, they will still receive blocks; however, they will be unable to synchronize with the rest of the network. This disconnection can lead to the validator’s unavailability and interrupted operations on the upgraded fork. To ensure uninterrupted participation and protect against penalties, all validators and full node operators must promptly switch to the release v1.0.12.
New rules and logic changes will occur for this upgrade on November 19th, 2024, around 07:00 AM UTC. After the upgrade, the blockchain can handle a series of new rules and logic, paving the way for enhanced performance and scalability features to make Core's ecosystem more efficient for its users.
The Fusion upgrade introduces breaking changes for enhanced scalability and performance, requiring prompt actions from validators and dApps running on Core to ensure uninterrupted operations. Following are the changes introduced in the Fusion upgrade:
Fusion Upgrade is a mandatory hardfork upgrade. Validator and Full Node operators must update their nodes to version 1.0.12 before 18 November 2024. The validator and full node operators must follow the following instructions to ensure a smooth upgrade to the latest release.
The Fusion Upgrade introduces significant breaking changes affecting developers and users interacting with Core's staking and delegation smart contracts. This upgrade replaces old contracts with new ones and introduces revised workflows for staking and delegating CORE, Bitcoin, hash power, and updated processes for claiming rewards. To understand these changes, refer to the detailed guidelines provided here.
If you fail to upgrade your software on time, your node will not sync with the upgraded Core blockchain peer/validator nodes, and you will not be able to connect or send transactions. It is also essential to upgrade on time to continue smooth, uninterrupted operations.
