- Avail’s blockchain network supports over 100 validators, offering robust stake distribution and reducing trust assumptions.
- Sophon’s use of validium over rollups allows for low transaction fees and high throughput, demonstrating economic efficiency.
- This development could lead to further innovations in Ethereum’s scalability solutions, with Sophon standing out in the validium space.
In a significant development for blockchain scalability, Sophon has become the first validium to bridge its data attestations to Ethereum. This achievement, announced here, marks a milestone in linking the Avail and Ethereum ecosystems, enhancing trust-minimized scalability for Ethereum.
Validium is a scaling solution that processes transactions off-chain while using zero-knowledge proofs to verify correctness on Ethereum. Unlike ZK-rollups, validiums keep transaction data off Ethereum to improve throughput and reduce costs. However, validiums introduce a trust assumption that transaction data could be withheld, potentially freezing funds.
To address this, Avail has launched a blockchain network optimized for managing decentralized transaction data at scale. Avail’s blockchain supports over 100 validators and offers a Nakamoto Coefficient of 35, providing a robust stake distribution. It also allows users to verify transaction data availability from their phones in approximately 40 seconds. This reduces trust assumptions and vulnerability concerns associated with validium architecture.
Why Sophon Opted for Validium
Sophon aims to become a leading platform for consumer-friendly blockchain products. A key aspect of this mission is ensuring a seamless user experience, as many users are not accustomed to paying for individual transactions online. By choosing validium over rollups, Sophon can maintain low transaction fees while enabling high throughput.
Even with Ethereum’s EIP-4844 upgrade, the majority of Ethereum blockspace is consumed by rollups. For instance, the Base rollup often uses a third of the available capacity, incurring significant fees. In contrast, Sophon has published over 10.5GB of data to Avail at a fraction of the cost, demonstrating the economic efficiency of validium.
Implications for Ethereum Scaling
L2beat, a service monitoring Ethereum scaling solutions, has indicated that chains posting data off Ethereum will soon require trust-minimized data availability attestations for classification as optimiums and validiums. This could reduce the current listings significantly, with Sophon standing out as the only validium using zero-knowledge proofs for transaction verification.
Sophon’s integration showcases how modern blockchain applications can scale to support high-throughput use cases while keeping costs low and maintaining trust-minimized verification. This development could pave the way for further innovations in Ethereum’s scalability solutions.
Why This Matters: Impact, Industry Trends & Expert Insights
Sophon has successfully integrated its validium solution with Ethereum, enabling data attestations that enhance scalability and trust-minimized verification on the blockchain.
In April 2025, Ethereum’s integration with ZKSync’s Validium mode was highlighted as a key trend in optimizing scalability. This development aligns with Sophon’s integration, demonstrating how Ethereum can support innovative applications by combining scalability with privacy. Bitrue
Industry adoption shows validity proofs, including Validium, account for approximately 25% of layer-2 solutions as of 2025. Validium is favored for enterprise networks prioritizing privacy and low-value transactions, which supports Sophon’s choice of validium for its scalability and cost-effectiveness. MEXC
