The zkEVM landscape is constantly evolving, with new projects emerging and existing ones maturing. Taiko stands out as a Layer-2 solution with a distinct approach, aiming to address the shortcomings of current zkEVM implementations. Following its recent airdrop and transition to mainnet, Taiko is positioned to make a significant impact on the Ethereum ecosystem. This article delves into Taiko’s unique features, its ecosystem, future roadmap, and its potential to contribute to a more scalable and decentralized Ethereum.
Taiko’s Differentiating Factors
Taiko distinguishes itself from other Layer-2 solutions through its innovative approach to zkEVM implementation, its unique Based Rollup architecture, and the experienced team behind the project. These factors combine to create a compelling narrative for Taiko’s potential to reshape the Layer-2 landscape.
Type 1 zkEVM Compatibility
Taiko falls under the category of Layer-2 projects utilizing zkEVM technology. This puts it in direct competition with prominent zkEVM projects like zkSync, Starknet, Linea, and Scroll. While other ZK projects (projects utilizing Zero-knowledge Proof technology) have faced challenges in achieving full EVM compatibility, Taiko’s Type 1 solution, introduced in late 2023, offers a refreshing approach.
Taiko’s Type 1 zkEVM boasts complete compatibility with the Ethereum Virtual Machine (EVM), preserving the existing Ethereum infrastructure. This brings several key advantages:
- Seamless dApp Development: Building and deploying dApps on Taiko mirrors the experience on Ethereum, simplifying the process for developers.
- Leveraging Ethereum Infrastructure: Taiko reuses much of Ethereum’s existing infrastructure, including node client software, hash functions, state trees, and gas mechanisms. This familiarity benefits both developers and users accustomed to the Ethereum ecosystem.
- Dual Functionality: Taiko’s solution can function as both a Rollup and a scaling solution for Ethereum itself, offering greater flexibility and potential impact.
However, Taiko’s approach also presents a trade-off:
- Higher Proof Generation Costs: Because Ethereum wasn’t initially designed for ZK proofs, generating these proofs for Taiko requires more computational time.
- Potential for Mitigation: Taiko acknowledges this challenge and anticipates future improvements through techniques like parallel proof generation and specialized hardware like ZK-SNARK ASICs.
Taiko’s rationale for choosing the Type 1 zkEVM path stems from the belief that the trade-off of higher proof generation costs is preferable to sacrificing EVM compatibility. They anticipate that technological advancements will eventually mitigate the cost concerns. This positions Taiko alongside Scroll and Immutable zkEVM as key players in the Type 1 zkEVM space. While not the first Type 1 zkEVM to reach mainnet, Taiko is the first to launch its native token.
Based Rollup Architecture: Decentralizing the Sequencer
One of Taiko’s most distinctive features is its “Based Rollup” architecture. Most existing Rollups face challenges related to the centralization of the Sequencer, the entity responsible for ordering transactions and submitting them to Layer-1. Typically, Rollups operate with a single Sequencer controlled by the project itself, granting significant power over the network. This centralization can create vulnerabilities, as demonstrated by Linea’s decision to temporarily halt its network to prevent a hacker from bridging funds.
Taiko’s Based Rollup architecture decentralizes the Sequencer by leveraging Ethereum’s existing validator set. Instead of relying on a separate consensus layer, Taiko utilizes Ethereum’s consensus mechanism, allowing Layer-1 validators to determine the order of transactions. This approach has several implications:
- MEV Capture: Validators can potentially extract MEV (Miner Extractable Value), incentivizing them to include rollup blocks alongside L1 blocks.
- Reduced Validator Load: L1 validators retain the discretion to include or exclude rollup blocks, and they don’t participate in L2 block construction, which is handled by L2 builders.
- Lower Transaction Fees: Utilizing L1 validators as L2 sequencers eliminates a layer of complexity and potentially reduces transaction costs.
- Block Finality Trade-off: Based Rollups may have slightly longer block finality times compared to Rollups with dedicated L2 sequencers.
- Potential for Optimistic Rollups: Optimistic Rollups could also adopt a similar mechanism to become Based Rollups.
Experienced Team with a Strong Track Record
Taiko’s team comprises experienced individuals with a proven track record in the ZK Rollup space. Many team members were previously involved with Loopring, one of the earliest ZK Rollup projects. They also collaborated with the Ethereum Foundation on zkEVM research and development in 2021. This deep understanding of Ethereum and ZK Rollup technology positions Taiko well to deliver on its vision for Ethereum scaling.
The Taiko Ecosystem: Early Stages of Development
Taiko’s innovative features have attracted over 100 dApps during its testnet phases and established partnerships with prominent projects like Etherscan, USDC, Pyth, and various DeFi and bridge protocols. Since its mainnet launch on May 27th, Taiko has seen over 60 projects deploy on its network.
However, the current ecosystem is still nascent. Most deployed projects are focused on wallets, tools, security, and infrastructure, with limited on-chain value. According to DefiLlama, only six DeFi projects on Taiko currently have measurable TVL, and these figures are still modest. The immediate airdrop following mainnet launch may have impacted Taiko’s ability to compete with other L2s like Linea and Scroll, both of which are running incentive programs to attract users and liquidity.
Despite its full EVM compatibility, Taiko hasn’t yet attracted many major DeFi projects. Existing DEXs on Taiko are primarily forks of other projects, like Ritsu (a Syncswap fork) and DaikoDEX and TaikoSwap (Uniswap V2 forks). A notable exception is Uniswap, which has a proposal to deploy Uniswap V3 on Taiko. While this is a positive sign, it’s still too early to assess the long-term viability of Taiko’s DeFi ecosystem.
Taiko’s Roadmap: Focusing on Innovation and Scalability
Following its mainnet launch, Taiko outlined its roadmap for future development, emphasizing product enhancements and further scalability:
- Based Contestable Rollup (BCR): An upgraded version of the Based Rollup, combining Based Sequencing (sequencing on L1) with a challenge mechanism similar to Optimistic Rollups, utilizing multi-proofs.
- Based “Booster” Rollup (BBR): A further enhancement of BCR, enabling cross-L2 transactions within the network while maintaining the benefits of L1 Sequencing.
- Inception Layers: Allowing the development of L3s on top of Taiko’s infrastructure.
Conclusion: A Promising Future with Challenges Ahead
Taiko presents a compelling vision for Ethereum scaling with its unique approach to zkEVM implementation and its innovative Based Rollup architecture. Its full EVM compatibility and focus on leveraging existing Ethereum infrastructure offer a smooth transition for developers and users. However, the ecosystem is still in its early stages, and Taiko faces competition from other L2 projects. The success of Taiko will depend on its ability to attract a thriving ecosystem of dApps and users, deliver on its ambitious roadmap, and contribute meaningfully to the long-term scalability and decentralization of the Ethereum network.
