From 6e4865c14c858d00c6cfa6967e66a86b31cd12f8 Mon Sep 17 00:00:00 2001 From: bitflash-maintainer Date: Sat, 8 Aug 2026 02:29:26 +0000 Subject: pool: sync-gate job creation, retry failed payouts; widen nostr relay set - RebuildJob: no jobs with zero peers or a tip older than 30min; mining unsynced produced orphaned blocks and payouts that can never be paid (observed in production: 8 orphan 'found blocks') - payout exec: on SendMoney failure requeue with 60s backoff, up to 30 attempts, instead of silently forfeiting the payment - nostr: add oxtr.dev, nos.social, fmt.wiz.biz, current.fyi, nostr.bg (12 relays total) for announcement redundancy (cherry picked from commit f1986cd7e4a6f69469a2256eb96ff03f3f146792) --- src/main.cpp | 318 ++++++++++++++++++++++++++++++++++++++++++++++++++--------- 1 file changed, 273 insertions(+), 45 deletions(-) (limited to 'src/main.cpp') diff --git a/src/main.cpp b/src/main.cpp index 0342650..32ab952 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -102,6 +102,9 @@ CAddress addrIncoming; int nMineMode = MINE_RELAY; bool fMineModeFromCommandLine = false; string strParticipantPool; // participant mode: pool .btf address +string strPayoutAddress; // participant: /payoutaddr override (mine without a wallet) +string strPayoutFile; // participant: /payoutfile with one address per line, rotated per reconnect +int nHashThreads = 0; // participant: /hashthreads override (0 = cores-1) string strPoolName = "Bitflash Pool"; string strPoolDashboardUrl; double dPoolFeePercent = 0.0; @@ -3488,6 +3491,102 @@ static bool StratumRecvLine(SOCKET s, std::string& buf, // How long to wait for a mining.notify after authorize before giving up static const int64 STUCK_NO_JOB_TIMEOUT_SECS = 120; +// ------------------------------------------------------------------ +// Multi-threaded pool worker.
