With the Ethereum ecosystem’s rapid expansion, it’s becoming increasingly challenging to manage proof verification costs efficiently. The cost varies depending on the proof system used and the availability of precompiles. Groth16 costs about 250,000 gas, STARKs costs over 1,000,000 gas, and other proof systems are too expensive to be used in Ethereum. So, finding a cheaper and faster way to verify proofs became really crucial.
This is where Aligned Layer steps in with its method to solve this through efficient algorithms and streamlined processes for verifying zero-knowledge proofs (ZKPs). Specifically, it wants to turn Ethereum into a super-efficient platform for verifying SNARKs (Succinct Non-Interactive Arguments of Knowledge).
Ethereum’s throughput is currently limited to around 10 proofs per second, however Aligned Layer’s third testnet which just launched can process more than 1,000 proofs per second.
So, how does Aligned Layer achieve this?
How Aligned Layer’s Proof Verification Works
Aligned Layer employs SNARKs (Succinct Non-Interactive Arguments of Knowledge) for proof verification. These cryptographic proofs allow for the verification of computations without revealing the underlying data. By using SNARKs, Aligned Layer significantly reduces the computational workload and costs associated with transaction validation, enhancing both efficiency and security on the Ethereum platform.
The proof verification process in Aligned Layer is designed to work efficiently with Ethereum’s validator network. It accepts proofs from various sources, each utilizing different systems such as Halo2, Gnark (Groth16), and Plonk + KZG. These proofs can vary significantly in size and verification time, but Aligned Layer’s system is designed to handle this diversity efficiently.
Dedicated verifiers within Aligned Layer examine these proofs and transmit the confirmed results to Ethereum. To optimize the process for Ethereum, which doesn’t directly verify these proofs due to high costs, Aligned Layer uses a Rust prover. This prover regularly generates a single, aggregated proof that encompasses all validated proofs within a specific timeframe. Although this aggregated proof can be large, it confirms the validity of all individual proofs collectively.
After validation, proofs are stored in a cost-effective data layer within the Aligned Layer ecosystem. This storage solution is designed to be both secure and easily accessible to Aligned Layer operators. By maintaining this separate data layer, Aligned Layer can manage large volumes of proof data without congesting Ethereum’s main network.
In terms of security, though Ethereum provides a baseline level of security, Aligned Layer’s soft finality mode offers security equivalent to Ethereum’s. On the other hand, Aligned Layer’s hard finality mode inherits Ethereum’s full security guarantees, providing the highest level of assurance for verified proofs.
Moreover, Aligned Layer incorporates slashing as an incentive mechanism to discourage malicious behavior in its decentralized network. Currently, two slashing options are under consideration: a short-term solution and a long-term plan.
In the short term, Aligned Layer employs subjective slashing. This approach requires agreement from two-thirds of the network’s operators to finalize and post results on Ethereum. Operators who disagree with the network’s decision face penalties. This system helps maintain Aligned Layer’s software lightweight and keeps hardware requirements low, making it easier for participants to join and incentivizing honest behavior.
For the long term, Aligned Layer is exploring an objective slashing plan for various proof systems. This approach would enable on-chain verification in Ethereum for certain integrated proof systems. For example, Cairo proofs verified in Aligned Layer could undergo similar checks in Ethereum if necessary. This setup allows honest operators or third parties to initiate a slash event if a majority of the network behaves maliciously. While this may slightly adjust security measures for each proof type, it generally enhances Ethereum’s overall security across various proof systems currently in use.
To further support developers, Aligned Layer plans to release a software development kit (SDK). This SDK will assist developers in verifying proof results within any smart contract, allowing them to focus on product development without the need to manage complex scaling infrastructure.
Economic Impacts of Aligned Layer’s Proof Verification
Aligned Layer has demonstrated that it is possible to reduce the cost of proof verification by 90% within the Ethereum ecosystem. The economic implications of Aligned Layer’s innovations are profound and far-reaching. By addressing one of Ethereum’s most significant pain points, Aligned Layer is poised to unlock new possibilities for developers, users, and businesses alike.
To put this in perspective, consider a decentralized application that previously required $100 worth of gas for each proof verification. With Aligned Layer’s solution, that same verification could potentially cost just $10, making many previously unfeasible applications economically viable.
Impact on Users and Developers
For individual users, the benefits of Aligned Layer’s approach are immediately tangible:
- Faster transaction times, reducing wait periods for confirmations
- Significantly lower fees, making Ethereum-based applications more accessible and affordable
- Improved user experience across a wide range of decentralized applications
On the other hand, developers get to allocate resources more efficiently and focus on enhancing product features rather than grappling with high operational costs.
Businesses leveraging Ethereum for smart contracts and DeFi applications benefit from improved scalability and cost predictability. They poentially get to serve a larger user base without sacrificing performance or incurring unsustainable costs.
Broader Market Implications
Aligned Layer’s cost reductions have far-reaching implications across the blockchain market. It enhances Ethereum’s competitiveness against other platforms. Lower entry barriers and operational costs attract more developers and businesses to Ethereum, potentially accelerating its adoption in mainstream applications.
Moreover, as blockchain technology becomes more economically viable, industries like supply chain management, healthcare, and digital identity verification are likely to explore blockchain solutions more actively, driving further market expansion and integration.
Concerns About Using Aligned Layer’s Proof Verification Solution
While Aligned Layer presents a compelling solution to Ethereum’s proof verification challenges, it’s important to acknowledge and address potential concerns and challenges that come with any significant technological innovation.
Security Risks
There are concerns about the security implications associated with relying on a new layer for proof verification. The implementation of novel algorithms and processes could potentially introduce vulnerabilities that malicious actors might exploit for data breaches or manipulation of transaction proofs.
Regulatory and Compliance Issues
Innovations in proof verification may pose regulatory challenges, particularly if they involve new cryptographic methods or processing techniques that regulators are unfamiliar with. Ensuring compliance with existing and future regulatory frameworks could delay widespread adoption.
Inclusion of Third-Party Operators
Integrating third-party operators into the proof verification process introduces dependencies and potential points of failure. Questions about the reliability, trustworthiness, and geographic distribution of these operators may arise, impacting the overall resilience and trust in Aligned Layer’s infrastructure.
Future Prospects for Aligned Layer
Despite these challenges, the future looks bright for Aligned Layer and its potential impact on the Ethereum ecosystem. The team behind Aligned Layer is committed to ongoing research and development, with several exciting initiatives on the horizon.
