Quick Start

1. Stratum Connection

In your miner's management panel, navigate to the Stratum configuration page and enter the following parameters to start mining:

       
        # Pool URL
       
       stratum+tcp://btcc.88pool.com:4444
       
        # Pool URL (TLS encrypted)
       
       stratum+tls://btcc.88pool.com:3334
       
        # Username (your BTC wallet address)
       
       bitcoin:qqj9rrt85mzdhf3mknppz7xvkxnxlxel9ynfku43nh
       
        # Password (any value)
       
       x
       
        # Fixed difficulty (high hashrate/rental, min 100000)
       
       d=500000
       
        # NiceHash Users: fully tested & compatible. Auto difficulty recommended (password: x). If fixed, use at least d=500000.
       
        # MiningRigRentals Users: auto or fixed difficulty both supported, no special requirements.

TLS Encrypted Connection — Using


         stratum+tls://

on port 3334, all data between your miner and the pool (hashrate, shares, wallet address) is encrypted via TLS, protecting against eavesdropping and tampering. This port requires miner firmware with TLS/SSL support. Miners without TLS support can continue using


         stratum+tcp://

on port 4444.

2. Wallet Address Requirements

Important: Solo mode requires a valid BTC wallet address as username. Supports CashAddr format (


         bitcoin:

or


         BTCreg:

prefix optional) and Legacy format (starting with

). Your address will be used directly for Coinbase transaction payouts — please ensure it is correct.

3. Worker Naming (Optional)

If you need to distinguish multiple miners, you can add a worker name after the address:

       
        # Username format
       
        [BTC_Address].[Worker_Name]
       
        # Example
       
       bitcoin:qqj9rrt85mzdhf3mknppz7xvkxnxlxel9ynfku43nh.rig1
       
       bitcoin:qqj9rrt85mzdhf3mknppz7xvkxnxlxel9ynfku43nh.rig2

Solo Mining Guide

What is Solo Mining?

Solo mining means you mine independently without sharing rewards. When you successfully find a block, the full block reward is sent directly to your wallet address via Coinbase transaction — no pool transfer needed, safe and efficient. Always 0% fees — 100% of rewards go to the miner, supported by voluntary donations.

Comparison with PPS/PPLNS

Mode	Earning Method	Risk	Suitable For
Solo	Get full reward when finding a block	High (may have no income for long periods)	Large hashrate miners / Lottery miners
PPS	Fixed payment per share	Low	Miners seeking stable income
PPLNS	Proportional allocation by shares	Medium	Long-term miners

Solo Mining Earnings Calculation

Expected earnings formula:


         Daily blocks = (Your hashrate / Network hashrate) × Total daily blocks (~144)


         Expected daily income = Daily blocks × Block reward

Note: Solo mining earnings are highly random. Miners with smaller hashrates may not find a block for months or even years, but a single block discovery yields the full reward. Please choose wisely based on your hashrate.

FAQ

Q: Why is my connection rejected?

A: Please verify your username is a valid BTC address. Solo mode requires a valid address as username. Supports CashAddr format ( bitcoin: prefix optional) and Legacy format (starting with 1 ). Ensure the address is correct with no extra spaces or special characters.

Q: Why are my shares always 0?

A: Share count depends on your hashrate and the pool's difficulty setting. If you just started mining, please wait a few minutes for the difficulty to auto-adjust. Also ensure your miner is operating normally with a stable network connection and no error logs.

Q: When will I receive payment?

A: In Solo mode, when you successfully find a block, the reward is directly written to your wallet address (via Coinbase transaction), no pool transfer needed. Available after block matures (100 confirmations).

Q: What is the pool fee?

A: Always 0% fees! All block rewards, including block subsidy and transaction fees, are 100% yours. Supported by voluntary donations.
