Your mining data may be visible on your network and you might not know it. When your miner connects to a solo mining pool without TLS encryption, the connection is unencrypted. Your Bitcoin address, worker name, and share data are sent in plaintext between your miner and the pool server. We tested the three biggest solo mining pools. Only two offer TLS. The most popular one with 299 confirmed blocks does not. We also break down one of the biggest misconceptions in solo mining: that a pool's block count improves your individual odds. It doesn't. The math is the same on every pool. Full comparison with on-chain verified data, fees, latency, TLS support, and self-hosting options: https://www.solosatoshi.com/best-solo-mining-pool/
