By using BlockBuilder, you agree to abide by all applicable laws and not engage in activities that harm the network, service infrastructure, or other users.

You must not attempt to reverse engineer, scrape, interfere with, or exploit the platform outside its intended use.

BlockBuilder is a platform that lets you deploy private solo Bitcoin mining pools with your own dedicated block templates and Web UI. You control the pool, payout address, and block composition.

You are responsible for your own mining activity, wallet address configuration, and legal compliance within your jurisdiction.

We charge a 0% development fee, transparently encoded in each block’s coinbase transaction. No custodial wallets are used and no funds are held on your behalf.

BlockBuilder is not responsible for block rewards, uptime, profitability, or earnings. This service is provided “as-is” without warranty or guarantee of any kind. You acknowledge mining is inherently probabilistic and may result in zero rewards.

Pools may be removed without notice if they are found to abuse system resources, spam the network, misrepresent origin, or sit idle for extended periods.

BlockBuilder collects only the minimum information required to run your account and pool infrastructure: your email, password hash, preferences, and settings.

We do not track your mining activity, hash rate, wallet balances, IP address, or worker behavior beyond what's needed to deploy and maintain your pool and Web UI.

No personal data is ever sold, shared, or monetized. Your pool and Web UI operate independently – we log your jobs, shares, and blocks for your Web UI statistics.

Your pool’s Web UI and mining server are deployed in isolated containers.

If you delete your account, all associated data is permanently removed from our systems.

We do not use third-party analytics, trackers, cookies, or advertising pixels anywhere on the platform.
