Where the numbers come from

• Chain data comes from the mempool.guide explorer, with mempool.kilombino.com as a backup. The two are compared on every update, and a notice appears if they disagree by more than 2 blocks.
• Supply, % issued, halvings and future supply are calculated from the block height using the 210,000-block halving schedule. Supply is the theoretical issued amount: it ignores coins that are unspendable or were never claimed.
• Price comes from public USD-stablecoin markets (NonKYC BTCB2/USDT and Neoxa XBT/USDC; Neoxa calls the coin XBT). USDT and USDC are counted as $1. These are thin markets, so treat the price as a rough guide. Price history starts Sep 1, 2026: earlier days were filled in once from Neoxa’s price history, and since then the site records the price every minute.
• Exchanges on the Converter page lists each market’s last price, bid and ask, and 24-hour volume. Neoxa’s XBT/USDT market is listed there but too thin to count toward the price. Neoxa trades through automated pools with no order book, so it has no bid or ask. The two Neoxa markets are the only links on this site to an exchange.
• Moving averages are plain averages of daily closing prices: the last 50 and 200 days, shown on the Converter page and as the 50 MA and 200 MA lines on the price chart.
• What’s in your block? on the dashboard reads the newest block from the same explorers and counts only what is data by definition: OP_RETURN outputs (how many, their total bytes, and which transactions have one) and inscription-style envelopes. Share of block is the OP_RETURN bytes divided by the block’s size; below 1% its bar is not to scale. Nothing else is guessed at, so large spending scripts such as multisig are not counted as data.
• Node counts on the Nodes page come from the B2B Node Census, an independent crawler of the XBT node network that publishes hourly. Reachable counts are a lower bound, because nodes that don’t accept incoming connections aren’t counted. This site shows counts only, never node addresses.
• The converter turns XBT, sats and US dollars into each other at the same live price, so it is as rough as the price is. World currencies convert that USD price at daily exchange rates from ExchangeRate-API (with the public Currency API as a backup).
• The mining calculator estimates earnings from today’s network hashrate, fees, block time and price, assuming they stay the same. Real mining rewards vary.
• Every number shows how old it is. If a source stops answering, the site keeps the last good data and labels it.
