Native Stratum V2

Protocol details

Transport: Native Noise_NX_Secp256k1+EllSwift_ChaChaPoly_SHA256 framing path with encrypted session negotiation.

Braiins: Tested interoperability path with compatibility handling for real-world Braiins Sv2 traffic patterns.

Compatibility: Channel-open accepts 0x10/0x11 and optional 0x1x variants; submit path handles 0x1A/0x1B/0x32 and optional 0x2x, with Braiins interoperability as a first-class target.

Validation bridge: Sv2 submits are mapped into the same core share checker used by production stratum paths.

SHA256d path: VERSION_MASK and V2 version-rolling integration support overt
ASICBoost-style version bit handling.

RTT Difficulty Explained

Quick guide for miners

RTT is an eCash target mechanism. The RTT KPI converts that target into a difficulty-style number (G/T) so it is easy to compare with normal network difficulty.

Higher RTT Difficulty means a harder target and fewer valid blocks on average.
Lower RTT Difficulty means an easier target and potentially more frequent valid blocks.
For a block to be valid, your share must satisfy the active RTT target as well as the normal block target.
RTT changes are normal when network conditions and template targets move.

Tip: if RTT Difficulty is above Chain Difficulty, RTT is the stricter gate for block validity right now.

Accepted and Rejected Shares

How share validation works and how miners can reduce rejects

Accepted means a submitted share met the current share difficulty target and passed validation. Rejected means the share did not pass one or more checks.

On this pool, Accept Always is disabled. Share quality is enforced by the active difficulty target, so invalid or stale shares are rejected instead of being force-accepted.

Common reject reasons

Share hash does not meet the assigned share target (difficulty too low).
Stale share after a new job arrived (high latency or delayed submit).
Duplicate share already submitted for the same job.
Invalid nonce or malformed submit payload.

How to reduce rejects

Use the closest stratum endpoint and stable low-latency network path.
Keep miner software and firmware updated.
Avoid overloaded rigs and verify clocks and power tuning are stable.
Use correct worker credentials and avoid duplicate worker sessions.

Tip: a small reject rate can happen naturally, but persistent spikes usually indicate network delay, unstable tuning, or a worker configuration issue.
