Optimism Announces Canyon Hardfork
Optimism announced the Canyon Hardfork, an upgrade to The Superchain that introduces support for Shanghai and Capella EIPs, bug fixes, and OP-Stack-specific changes. The deployment is scheduled for the OP Sepolia, OP Goerli, Base Sepolia, Base Goerli, PGN Sepolia, and Zora Sepolia testnets on November 14th at 17:00 UTC. Canyon also adjusts the EIP-1559 basefee change rate and protocol handling for unclosed channels, enhancing network efficiency. Testnet node operators are required to update their clients to be compatible with the Canyon Hardfork. The upgrade will need to undergo Optimism governance approval before it can be deployed on mainnet.

Sound.xyz Introduces Gas-Free Uploads

Sound.xyz introduced gas-free music uploads on OP Mainnet. Coined as Magic Uploads, artists can now upload their music without needing a wallet or ether for gas fees. Users can create an account with just an email and have a wallet created for them. The initial upload gas fees are likely subsidized by the protocol. Editing and balance withdrawals still incur gas fees.

Type-1 zkEVMs enable EVM bytecode-level compatibility, allowing developers to seamlessly port their applications to the rollup.
