Security Man-in-the-middle attack prevention.

Data transfers can be encrypted to ensure their integrity and confidentiality. This hardens the protocol against man-in-the-middle attack vectors, namely hashrate hijacking in which an attacker intercepts a miner’s shares and submits them as their own in order to steal the payouts.

Efficiency Going binary to optimize data transmission. V2 has a fully binary format and eliminates unnecessary data transfers. This saves “a bit” of network bandwidth (about 2-3x times in comparison with Stratum V1) and decreases latencies.

Besides lowering infrastructure costs, Improved efficiency reduces hashrate variance by allowing higher submission rates, resulting in fewer stale share submissions.

Flexibility Built to fit the needs of any sized mining operation.

Whether you operate a huge mining farm or just a couple of ASICs in your garage, Stratum V2 will make your life easier. Features like simplified header-only mining, zero-time backend switching, and many more allow for all sorts of unique setups

At the same time, Stratum V2 is designed to be easily extensible so that it can evolve to meet the needs of the mining industry for years and maybe even decades to come.
