Foundry Makes BTC Donation to Open Source Stratum V2 Protocol Developer to Improve Bitcoin's Proof-of-Work Mining Layer

ROCHESTER, N.Y., Aug. 3, 2022 /PRNewswire/ -- Foundry Digital LLC ("Foundry"), a leading service provider for institutions in the digital asset mining and staking industry, announced a grant of 1 Bitcoin (BTC) to 4ss0, a pseudonymous developer working on Stratum V2, an open-source protocol that defines how bitcoin miners, proxies and mining pools communicate to contribute hashrate to the bitcoin network.

Stratum V2 brings much needed improvements to the Proof-of-Work coordination layer that connects the miner and the pool, providing greater levels of efficiency, security and decentralization. By changing the default messaging to binary rather than JSON and adding encryption, Stratum V2 materially improves the communication between miner and pool over the existing Stratum protocol.

While these are major improvements in their own right, the developer will use the funds to focus on the implementation of the Job Negotiation Protocol in Stratum V2. Job Negotiation is a Stratum sub-protocol that allows miners to construct their own block templates and will further iprove the censorship resistance of Bitcoin by decentralizing block template creation.

In addition to the BTC grant, Foundry will connect the developer and Stratum V2 team with the Foundry USA Pool team as well as offer access to bitcoin ASICs and hashrate for testing purposes.

"The bitcoin mining industry has evolved rapidly in the past two years, while the underlying protocol that coordinates the miner and the pool has stayed stagnant," Jay Beddict, VP of Research at Foundry, said. "Foundry views Stratum V2 as a major improvement to the current Stratum protocol and is aligned with our mission of empowering decentralized infrastructure. The Job Negotiation Protocol specifically is critical to the further decentralization of the mining industry and the hardening of Bitcoin's censorship resistance. We look forward to the developments in this space and are proud to support the open-source community."

4ss0 added: "The Job Negotiator implementation will increase the decentralization of pool mining, enabling miners to mine their chosen transactions while preventing the censorship of transaction propagation by pools. This will further allow people around the world to benefit from Bitcoin's borderless freedom."

While commonly associated with bitcoin mining, the Stratum protocol is also the standard for communication between miners and pools of other proof of work digital assets, like Ethereum, Zcash, and Monero. Work on open-source Stratum V2 reference implementations could filter down to other protocols and increase efficiency, security, and decentralization across the industry.

The grant will be disbursed over the course of the developer's work on the project.
