bitcoin-blake2b.org, btc-blake2b.org, btc-blake2b.com, and bitcoin-blake2b.be serve the same pages. They explain Bitcoin with the BLAKE2b algorithm, and the BIP-110 events that inspired this hardfork. This hardfork is not BIP-110.
The HTML for these pages is published at github.com/innerhat-dev/bitcoin-blake2b.org.
1. Information we collect
These pages are static files. They do not create accounts, take payments, or run third-party advertising or analytics SDKs.
The origin web server may record standard request logs such as IP address, user agent, requested path, referrer, and timestamps. Requests also pass through Cloudflare before they reach the origin. Cloudflare may log those same kinds of fields and may send network-error reports to operate the edge. Those logs are used to operate the site, diagnose failures, and protect against abuse.
2. Cookies
These pages do not set first-party tracking cookies. Cloudflare may set its own cookies for security or to distinguish automated traffic. If your browser stores a cookie from a previous visit to another site on the same machine, that is outside this site's control.
3. Links
Pages link to Bitcoin Knots, Knots source and release notes on GitHub, the DATUM Gateway at CONVOY, the Bitcoin white paper, and the site source repository. Those sites have their own policies.
