BTX replaces Bitcoin's SHA-256 with MatMul, a matrix multiplication over a finite field. That work proof is most of every block, so a block stays about 1 MB even when it carries a single transaction.

Nothing on this site is financial advice. We are independent: not affiliated with, and not speaking for, the BTX core team, and we never sell, broker or hold coins. The BTX price here is a modeled estimate published by btxprice.com, an independent third party we have no part in and no control over. BTX has no public order book, so that number is a model, not a market price, which is exactly why we label it modeled. We read it, we do not set it and we cannot vouch for it. We are here because we think BTX is worth building on.
