<\/p>\nJuly was a month of shrinking block rewards. Ethereum Classic cut its block reward by 20% under ECIP-1017, Kaspa went through another scheduled reduction, and Zcash activated the Ironwood upgrade that closes the Orchard flaw we reported last month. We also refreshed our Zcash, Nervos, and Pearl nodes and rotated the SSL certificates on all pools.<\/p>\n
<\/p>\n
<\/p>\n
In accordance with the Ethereum Classic Monetary Policy<\/a> and the ETC emission schedule defined in ECIP-1017<\/a>, the block reward dropped again in July. The reduction happens every 5,000,000 blocks and takes 20% off the reward each time. This one landed at block 25,000,001<\/strong>.<\/p>\n Please pay attention!<\/strong> This is a 20% cut to what every ETC block pays out, and it applies to POOL and SOLO alike. We have already updated 2CryptoCalc<\/a> with the new reward, so the numbers you see there are current.<\/p>\n Mining continues as usual on the ETC pool<\/a> and ETC SOLO<\/a>. No configuration changes are needed on your side.<\/p>\n As defined by the Kaspa Tokenomics<\/a>, the Crescendo Hard Fork, and the official emission schedule, Kaspa underwent another scheduled block reward reduction in July.<\/p>\n Please pay attention!<\/strong> Kaspa mining profitability has changed. We have already updated 2CryptoCalc<\/a> to reflect the new reward values. Mining continues on the KAS pool<\/a> and KAS SOLO<\/a>.<\/p>\n Last month we reported the emergency response to the Orchard soundness flaw. July closed that chapter. The Ironwood<\/strong> network upgrade \u2014 formally NU6.3<\/strong> \u2014 activated on mainnet at block 3,428,143<\/strong> on July 28, sealing the old Orchard pool and routing the shielded supply through a public accounting checkpoint known as the turnstile. The upgrade had been pushed back one week from July 21 specifically to give exchanges, wallets, and mining pools time to prepare.<\/p>\n Two things happened around it that matter to node operators:<\/p>\n Our ZEC node runs Zebra 6.2.3<\/strong> (commit 7121c82). Beyond Ironwood compatibility, the release is about network resilience: peers are no longer penalized for branch ID mismatches during the 40-block window around activation, the stall detector stops disconnecting peers near the chain tip, and outbound connection slots no longer clog with non-serving peers.<\/p>\n What it means for miners on 2Miners:<\/strong> nothing changes in your setup. Equihash mining and payouts ran normally through the activation. If you run your own node, migrate to Zebra \u2014 zcashd is no longer maintained. Mining continues on the ZEC pool<\/a> and ZEC SOLO<\/a>.<\/p>\n Nervos shipped twice in July and we took both. Neither is a mandatory upgrade: all networks stay on the ckb2023 consensus version, and there are no protocol changes in either release.<\/p>\n 0.208.0<\/strong> (commit 585395c, July 14) is routine maintenance \u2014 the live cell RPC response now includes the block hash, plus dependency upgrades, a Windows runtime fix, and a rotation of the release signing key. Nothing mining-specific.<\/p>\n 0.209.0<\/strong> (commit d166e28, July 29) is the more useful one for anyone running their own node:<\/p>\n Eaglesong mining is unaffected. Mine on the CKB pool<\/a> and CKB SOLO<\/a>.<\/p>\n Our Pearl node is now on 1.2.1<\/strong> (commit e72ad36), a maintenance release following the network’s move to v2 certificates in June. PearlHash mining is unchanged. Pearl runs on both PRL POOL<\/a> and PRL SOLO<\/a>, and profitability is on 2CryptoCalc<\/a>.<\/p>\n We rotated the SSL certificates across all pools and restarted the stratum servers with the new certificates. If your miner logged a brief reconnect in July, this is the most likely reason. No action is required \u2014 mining resumed automatically, and connections using TLS stratum ports continue to work with no configuration change.<\/p>\n Follow us on X (Twitter)<\/a> and join our Telegram chat<\/a> to stay informed about new developments, miner alerts, and network upgrades.<\/p>\n","protected":false},"excerpt":{"rendered":" July was a month of shrinking block rewards.
