Optimism (OP) Prepares for Canyon Hardfork Across Superchain Testnets on November 14

The Optimism ecosystem is set to embrace a milestone with the Canyon hardfork, slated for activation on the OP Goerli, OP Sepolia, Base Goerli, Base Sepolia, PGN Sepolia, and Zora Sepolia testnets on November 14, 2023, at 17:00 UTC. Announced by the OP Labs Team on November 7, 2023, this upgrade follows the previous Bedrock network enhancement and is eagerly anticipated across the Superchain.

Collaboratively developed with Base, the Canyon hardfork has undergone successful initial activation on a devnet, paving the way for its deployment on testnets. A subsequent rollout to the OP Mainnet and other Superchain mainnets will depend on the Optimism governance protocol’s approval.

Canyon’s launch brings with it several improvements including Shanghai and Capella hardfork support, alongside a series of minor bug rectifications. Noteworthy EIPs—EIP-3651, EIP-3855, EIP-3860, EIP-4895, and EIP-6049—are incorporated, featuring enhancements like new Ethereum instructions, the phasing out of the SELFDESTRUCT function, and modifications for beacon chain push withdrawals.

A crucial update within Canyon is the fine-tuning of EIP-1559, which adjusts the basefee’s sensitivity to network congestion. This aims to moderate the speed of basefee adjustments, fostering a more stable network fee environment.

Protocol modifications also include improved handling of unclosed channels, allowing for uninterrupted operation progression in certain scenarios. A new field in the deposit transaction receipt encoding is also introduced to correct a discrepancy in the nonce consensus.

Furthermore, the hardfork ensures the deployment of the create2Deployer bytecode across all networks, enabling consistent access to this critical contract for developers.

While end-users may not experience direct impact from these upgrades, node operators are required to update their nodes to conform to the new Canyon specifications. Detailed instructions are available through a publicly accessible guide. Participants in the Optimism ecosystem should watch for upcoming governance updates, which will signal the potential mainnet integration of the Canyon hardfork.

Base Unveils Its Decentralized Superchain Vision Powered by OP Stack

Base, the Ethereum Layer 2 (L2) solution incubated at Coinbase, recently spotlighted its unwavering dedication to decentralization, aligning seamlessly with the Superchain vision. Born out of a collaboration with the Optimism Collective, Base utilizes the open-source OP Stack, aiming to bring a billion users and a million developers into the blockchain ecosystem. This ambitious goal is anchored in the principle of decentralization, seen as the linchpin for a global, open, onchain economy. 

The OP Stack, maintained by the Optimism Collective, is the open-source development stack that powers Optimism. It comprises various software components that together form Optimism’s backbone, designed as a public good for both Ethereum and Optimism ecosystems. The stack’s primary focus is on creating a shared, high-quality system for generating new L2 blockchains.

This coordination on shared standards helps avoid repetitive software creation in isolated silos. While the current core of the OP Stack is infrastructure for L2 blockchains, it extends to tools like block explorers, governance systems, and more. The Bedrock release of the OP Stack supports the Optimism Superchain, a proposed network of L2s sharing security, communication layers, and a common development stack.

The choice of the OP Stack as the foundation is strategic. Recognized as a universally accessible asset, it beckons every developer. As teams like Base and OP Labs converge, the mission is clear: reinforce the OP Stack. This shared aspiration with the Optimism teams paints a picture of Ethereum’s future—a “Superchain” of interconnected rollups and L2s.

Base’s commitment to decentralization isn’t just theoretical. The platform is on a quest to decentralize its core while bolstering the OP Stack. With technical advancements on the horizon, Base aims to transition from a Stage 0 to a Stage 2 L2, a categorization attributed to Ethereum’s co-founder, Vitalik Buterin. This collaboration with the Optimism Collective promises to elevate the OP Stack’s trifecta of scalability, reliability, and decentralization.

On the technical front, Base’s roadmap is laden with milestones. From refining op-geth and op-node for enhanced scalability to backing the op-reth initiative for diversified clients, the path is well-defined. Additionally, the advent of “Pessimism” is set to amplify the OP Stack’s monitoring prowess.

Base’s allegiance to the “Law of Chains” is steadfast. This framework sketches out standards for Superchain protocols, emphasizing neutrality and a decentralized security model. It also offers a protective shield for users and operators. Base’s launch strategy is meticulously crafted to obliterate centralization bottlenecks.

In a philanthropic stride, Base pledges to allocate a portion of its sequencer revenue to the Optimism Collective. This contribution is earmarked as either 2.5% of Base’s sequencing revenue or 15% of L2 transaction profits after accounting for L1 data submission costs. Moreover, Base’s foray into onchain governance is commendable, with prospects of acquiring up to 2.75% of the OP token supply over six years.

In conclusion, Base’s fervor for the Superchain vision is palpable. In synergy with the Optimism Collective, the objective is lucid: establish a robust foundation for the OP Stack and the Superchain, heralding a new era in the blockchain realm.
