From 1363191270f4886e189e59ac70ce42bc3f7a6125 Mon Sep 17 00:00:00 2001 From: frstrtr Date: Sun, 12 Jul 2026 12:30:21 +0000 Subject: [PATCH] ltc/doge: G3b live-regtest genuine block-production driver Live-daemon counterpart to the in-process G3a harness: real litecoind + dogecoind(-regtest) merged-aux, real c2pool cutover build, real scrypt miner, real coinbase through submitblock, staged v35->v36 activation crossing, and the auxpow parent-LOST -> aux-DROPPED invariant against live c2pool state. Ready to run the instant the regtest testbed VM is stood up; regtest-only, never force-activates prod (natural-vote hard gate). Per-coin LTC(+DOGE aux) isolated. --- .../ltc_g3b_live_regtest_blockprod_driver.sh | 121 ++++++++++++++++++ 1 file changed, 121 insertions(+) create mode 100755 scripts/ltc_g3b_live_regtest_blockprod_driver.sh diff --git a/scripts/ltc_g3b_live_regtest_blockprod_driver.sh b/scripts/ltc_g3b_live_regtest_blockprod_driver.sh new file mode 100755 index 000000000..64db6624d --- /dev/null +++ b/scripts/ltc_g3b_live_regtest_blockprod_driver.sh @@ -0,0 +1,121 @@ +#!/usr/bin/env bash +# ltc_g3b_live_regtest_blockprod_driver.sh +# ----------------------------------------------------------------------------- +# Greenlight gate G3b -- LTC (+DOGE aux) GENUINE block production on a LIVE +# regtest testbed.
