Blitzpool natively supports the next-generation Stratum V2 mining protocol. Encrypted connections, binary framing, and decentralized job declaration — all auto-detected on the same ports you already use.
All communication is encrypted via the Noise Protocol framework. No separate SSL port needed — privacy is built in.
Compact binary framing replaces JSON text. Less bandwidth, lower latency, faster share submissions.
Miners can propose their own block templates — choose which transactions to include and help decentralize Bitcoin mining.
Same ports as Stratum V1. The pool auto-detects the protocol. Just point your SV2-capable miner at the pool and go.
Use the same connection details as Stratum V1. The pool automatically detects whether your miner speaks V1 or V2.

stratum2+tcp://blitzpool.yourdevice.ch:3340/9bCoFxTszKCuffyywH5uS5o6WcU4vsjTH2axxc7wE86y2HhvULUStratum V2 is supported by a growing number of mining devices and software.
We authored Stratum V2 client implementations for two popular open-source ASIC firmwares. NerdQAxe Plus has shipped; Bitaxe is currently under review upstream.
Stratum V2 is an open protocol developed by the community. Read the full specification and learn about the protocol design.
