Software used in bitcoin mining just got its first upgrade since late 2012, and a coalition of companies including payments giant Block (formerly Square) is trying to help push the open-source protocol forward to become an industry standard.
The move could help open bitcoin mining to more participants by supporting lower-quality internet connections, as well as improving security so miners get properly compensated for their work.
Bitcoin operates on a proof-of-work mining model, meaning that miners around the world run high-powered computers to create new bitcoin and validate transactions. Mining requires professional-grade equipment, some technical know-how, a lot of electricity and a special kind of software.
Rather than directly accessing the bitcoin protocol, the vast majority of miners today work through an intermediary protocol called Stratum, which facilitates communication between the bitcoin network, miners, and the mining pools that combine the hashing power of thousands of miners all over the world.
Miners use Stratum to submit their work and to collect a reward if they successfully complete a new block of transactions.
On Tuesday, a coalition of bitcoin developers is releasing version 2 of Stratum under an open-source license for the mining industry to evaluate and test.
It will take some work to convince the mining industry to adopt the new protocol, so Spiral — a subsidiary of Jack Dorsey’s payments company Block (formerly Square) — is teaming up with bitcoin mining company Braiins to launch a group to test and fine-tune the open-source software before they push mass adoption.
What the upgrade does
Steve Lee, the lead at Spiral, tells CNBC there are several significant benefits to the upgrade, including cutting down on the use of data.
Currently, it is common for each mining rig in a large farm to directly connect to a pool. This setup wastes a lot of energy. Lee says that Stratum V2 supports a proxy that aggregates all the connections and only establishes one connection with the pool.
The process of sending that data is also changing to a more efficient method.
“All told, much less data needs to be transmitted between miners and pools, and this could help miners in remote regions of the world with poor internet,” noted Lee.
The upgrade is also designed to improve security. Today, it is possible to steal hash rate from a miner, which can lead to some miners losing money. Hash rate is a term for the collective computing power of the bitcoin network. To resolve this, Lee says Stratum V2 introduces a standard security mechanism with authentication and encryption between miners and pools.
The version being released Tuesday is for initial testing, and in early November, a more robust version will come out that supports additional functionality, including job negotiation — a “feature that represents a historic shift in the…
