The Sui devnet has been upgraded to version 1.79.0, marking a significant milestone in the development of the Sui protocol. This upgrade introduces several key changes, including the addition of protocol versions 135 and 136, and new feature flags for transaction expiration and TxContext restrictions.
One of the most notable changes is the addition of protocol versions 135 and 136. Protocol version 135 introduces a new feature flag called `ptb_tx_context_restrictions`, which restricts the way transactions can use TxContext in a PTB Move call signature. This change aims to improve the security and reliability of transactions on the Sui network.
Protocol version 136, on the other hand, introduces a new invariant check around packages, which helps to prevent errors and ensure the integrity of the Sui network. Additionally, this version also bounds the arena a package is loaded into by the Move VM, which helps to improve the performance and efficiency of the network.
Another significant change is the introduction of a new feature flag called `allowed_proposers`, which restricts the transaction to a named set of consensus proposers. This change aims to improve the security and reliability of transactions on the Sui network by ensuring that only authorized proposers can propose transactions.
The upgrade also includes several other changes, including the addition of a new invariant check around packages, and the modification of the `SimulateTransaction` gRPC method to return a `VALIDITY` expiration carrying the validators allowed to propose the transaction.
Overall, the upgrade to version 1.79.0 represents a significant step forward for the Sui protocol, and is expected to improve the security, reliability, and performance of the network. As the Sui network continues to evolve and grow, it will be interesting to see how these changes impact the development of the protocol and the wider cryptocurrency ecosystem.
The Sui devnet upgrade is a significant development for the Sui community, and highlights the ongoing efforts of the development team to improve the security, reliability, and performance of the network. As the Sui network continues to grow and mature, it will be essential to monitor the impact of these changes and ensure that the network remains secure and reliable.
In conclusion, the upgrade to version 1.79.0 represents a significant milestone in the development of the Sui protocol, and is expected to have a positive impact on the security, reliability, and performance of the network. As the Sui community continues to grow and evolve, it will be essential to stay up-to-date with the latest developments and changes to the protocol.
