S256 - Mining

Mining Pools

Sha256-Mining and Rodb’s pool both took part in testing S256 merged mining on testnet3 before v3.0.1.

Sha256-Mining Pool

sha256-mining.go.ro

Modes: PROP pool (default) or solo
Fee: 1% (pool and solo)
Payouts: Hourly, minimum 1 S256
Rewards mature: After 201 confirmations

Stratum URL	Start diff	Solo merged mining
`stratum+tcp://sha256-mining.go.ro:50272`	15K	+ VMESH
`stratum+tcp://sha256-mining.go.ro:50273`	50K	+ VMESH
`stratum+tcp://sha256-mining.go.ro:50274`	250K	+ VMESH
`stratum+tcp://sha256-mining.go.ro:50276`	1M	+ VMESH
`stratum+tcp://sha256-mining.go.ro:50277`	250K	+ ESF

VarDiff adjusts each miner’s difficulty, so the start difficulty only sets where it begins. Solo miners also merge-mine VMESH or ESF on the same hashes when they add vmesh= or esf= with their address to the password.

Rodb’s Pool

pool.rodb2008.com

Modes: Solo, ASICBoost supported
Fee: 2% (also 2% on merged-mined blocks)
Payouts: In the block’s coinbase, straight to your address
Merged mining: ESF and VMESH on every port
Password: x

Stratum URL	Start diff	For
`stratum+tcp://rodb2008.com:6156`	2048	Low-hash ASICs

`stratum+tcp://rodb2008.com:6356`	500K	NiceHash / MRR

Username: YOUR_S256_ADDRESS.worker. Every S256 share is also checked against the ESF and VMESH targets at no cost to your hashrate. Found ESF and VMESH blocks pay the pool’s default addresses unless you add your own: YOUR_S256_ADDRESS+esf:YOUR_ESF_ADDRESS+vmesh:YOUR_VMESH_ADDRESS.worker

Run by RodB, who tested S256 merged mining with mkpool and helped get the v3.0.1 auxpow format right. The pool runs S256 Core v3.0.1.

Modes: Solo

A no-account, non-custodial solo pool for many SHA-256 coins; S256 has its own port. When your miner finds a block, its coinbase transaction has two outputs: 99% of the reward to the address you mine with and the 1% fee to the pool. The pool never holds your coins.

Coinbase payouts

The coinbase is the first transaction in every block: it creates the new block reward. Pools that pay in the coinbase write your address into that transaction, so the reward lands in your wallet the moment the block is mined, with no pool balance, payout threshold or withdrawal. A pool that splits the coinbase adds more outputs to the same transaction, for example its fee. Like every block reward, coinbase coins can be spent after 200 confirmations; until then your wallet shows them as immature.

Setup Guide

From a new wallet to your first payout in four steps.

Get an S256 address

Install a wallet or open the web wallet and create a receiving address. S256 addresses start with s21 (bech32), S or 8. Pools pay to this address, so keep its keys or seed phrase backed up.

Pick a pool and a port

Choose a pool above. On Sha256-Mining, pick the port whose start difficulty is closest to what your miner handles; a small miner goes on 50272, a large farm or rental on 50276. VarDiff tunes it from there.

Configure your miner

In your ASIC’s pool settings, enter:

URL: stratum+tcp://sha256-mining.go.ro:50273
Username: your-s256-address.worker1
Password: x for pool mining, m=solo to mine solo

The part after the dot is a worker name of your choice, so you can tell several miners apart.

Watch shares and payouts

Within a few minutes the pool shows your hashrate. Block rewards unlock after S256’s coinbase maturity (200 blocks; the pool waits for 201 confirmations) and are then paid out with the next payment run.
