Bitcoin Core 31.0: SOLO Pool Node Up to date
We upgraded the node behind our BTC SOLO mining pool to Bitcoin Core 31.0, the most recent main launch. Block templates are actually constructed on the brand new cluster-based mempool, and the discharge continues the migration of the mining interface to the multiprocess IPC structure.
What modified:
- Cluster mempool. Transaction ordering was rebuilt round clusters, bettering how block templates are assembled and the way fee-bumping (RBF and CPFP) is evaluated.
- Mining interface (IPC). Block-template creation moved additional towards the separate mining interface; coinbase knowledge is now returned in structured type.
- Node efficiency. The default database cache was raised to 1024 MiB on machines with 4 GB+ of RAM, and the fee-estimation flooring was lowered to 0.1 sat/vB.
Nothing modifications for you as a SOLO miner — we run and keep the node. Level your SHA-256 {hardware} at solo-btc.2miners.com:2626 together with your Bitcoin deal with because the employee title. In case your rig finds a block, the total reward (3.125 BTC plus charges) is yours.
Quai (QUAI) Node Replace: go-quai v0.53.0 (BIP-302 Fork)
Quai activated the BIP-302 consensus fork with go-quai v0.53.0 on Might 15, 2026. We up to date our Quai nodes forward of activation, so the QuaiKawPow and QuaiSHA swimming pools stayed in sync by the fork.
Key modifications for miners:
- Reward recalculation. The fork renormalizes Quai’s block reward towards SHA-equivalent problem; KawPoW problem is now expressed in SHA phrases.
- Brief conversion freeze. A short maintain interval utilized across the fork’s activation window.
- Stability fixes. Added a restoration step when Prime/Area/Zone headers are out of sync on restart.
Mining is out there on the QuaiKawPow and QuaiSHA swimming pools, with SOLO choices for each.
Zcash (ZEC) Node Replace: Model 6.12.3 — Safety Hotfix
Zcash launched v6.12.3, a safety hotfix that we utilized to our ZEC pool node instantly.
The discharge fixes CVE-2024-52911, a essential use-after-free vulnerability in block validation. Any inbound peer might set off it by sending a crafted invalid block, crashing the node throughout script verification — and bouncing invalid blocks between friends might amplify a single crash right into a network-wide outage. Each multi-core node working the default settings was affected on v6.12.2 and earlier.
If you happen to run your individual Zcash node, improve to 6.12.3 immediately. Our pool node is already patched.
Ergo (ERG) Node Replace: Model 6.0.3-RC1
Ergo printed 6.0.3-RC1, a launch candidate centered on block propagation and mempool dealing with. We’re testing it towards our ERG pool node.
Notable modifications:
- Quicker block announcement. A brand new block is now introduced to friends instantly, earlier than full validation — this reduces propagation delay and helps decrease stale/orphan charges for miners.
- Mempool enhancements. Higher dealing with of fee-based transaction alternative and a repair for duplicate transaction IDs.
As a launch candidate, 6.0.3-RC1 is a pre-release; we’ll transfer our pool to the secure construct as soon as it ships.
Kaspa (KAS) Block Reward Discount
As outlined by the Kaspa Tokenomics and its clean month-to-month emission schedule, Kaspa underwent one other scheduled block reward discount in Might.
- Earlier Reward: 2.914 KAS
- New Reward: 2.75 KAS
Please concentrate! Kaspa mining profitability has modified. Now we have already up to date 2CryptoCalc to replicate the brand new reward values. Mining is out there on the KAS pool and KAS SOLO.
Nexa (NEXA) Block Reward Discount
In step with the Nexa tokenomics, the Nexa block reward was halved in Might.
- Earlier Reward: 10,000,000 NEXA
- New Reward: 5,000,000 NEXA
Please concentrate! Nexa mining rewards per block have been lower in half. Now we have up to date 2CryptoCalc accordingly. Mining is out there on the NEXA pool and NEXA SOLO.
