Ethereum Foundation Offers $2 Million Bounty for Fusaka Upgrade Security

Sep 16, 2025

3 min read

The Ethereum Foundation has launched a significant security initiative, offering a $2 million reward pool for researchers to identify vulnerabilities in its upcoming Fusaka upgrade. This contest aims to bolster the network's security and efficiency before the upgrade's mainnet deployment.

Key Takeaways

  • $2 Million Security Contest: The Ethereum Foundation is incentivizing researchers to find bugs in the Fusaka upgrade.

  • Fusaka Upgrade Focus: The upgrade aims to enhance scalability and transaction throughput through features like Peer Data Availability Sampling (PeerDAS).

  • Timeline and Testing: The contest runs from September 15 to October 13, with increased rewards for early submissions. The upgrade is slated for testnet deployment starting September 29, with mainnet activation dependent on successful testing.

  • Sponsorship: Gnosis and Lido are co-sponsoring the initiative, contributing $100,000 and $25,000 respectively.

Enhancing Ethereum's Scalability

The Fusaka upgrade is designed to introduce several technical improvements aimed at boosting Ethereum's scalability and transaction throughput. Key features include Peer Data Availability Sampling (PeerDAS), which will streamline data distribution across the network, and revised gas limits and blob parameters to optimize performance and handle higher transaction volumes.

These enhancements are crucial for Ethereum to maintain its competitive edge, especially during periods of high network activity and the emergence of "alt-seasons" where alternative cryptocurrencies gain traction. The upgrade aims to make Ethereum a more reliable and cost-effective settlement layer for decentralized applications and layer-2 rollups.

Security Audit Contest Details

The security contest, hosted on the Sherlock testnet, will run for four weeks, from September 15 to October 13. To encourage prompt participation and thorough auditing, rewards will be amplified for vulnerabilities discovered in the earlier weeks of the contest. Findings reported in the first week will receive double points, while those in the second week will get a 1.5x multiplier. This phased approach ensures critical scrutiny during key development stages.

Sponsorship and Ecosystem Support

The initiative has garnered support from prominent players in the Ethereum ecosystem, with Gnosis and Lido acting as co-sponsors. Gnosis has contributed $100,000, and Lido has added $25,000 to the reward pool. Their participation underscores the broader ecosystem's vested interest in the security and success of Ethereum's upgrades, benefiting all users, developers, and validators.

Potential Challenges and Timeline

While the Fusaka upgrade promises significant advancements, its development is not without potential hurdles. Some observers have raised concerns about the timing of the audit contest, given that developers are still identifying bugs on Fusaka's devnets. The Ethereum Foundation has clarified that the mainnet activation date is not yet fixed and is contingent upon the successful deployment and performance across various testnets, including Holesky, Sepolia, and Hoodi. Mainnet activation will only proceed after all testnets are upgraded successfully and analysis confirms the network is operating as expected.

Investor Perspective

From an investor's standpoint, the Fusaka upgrade could significantly impact ETH's tokenomics and market position. Potential benefits include improved staking dynamics, increased layer-2 growth due to lower fees, and a reinforced competitive standing for Ethereum as the primary infrastructure play in the crypto market. However, risks such as execution delays and the continuous innovation by competing chains remain factors to monitor.
