ViaBTC, a mining pool, has sold the first satoshi mined after the recent Bitcoin halving for $2.13 million at an auction on CoinEx. The Ordinals protocol has allowed for individual satoshis to be identified and traded, giving value to specific sats for the first time. The satoshi, with a face value of around $0.0006, was expected to attract significant interest and was categorized as "epic" under the Ordinals system due to being the first after a quadrennial halving. The advent of the Ordinals protocol has allowed sats to be traded like unique tokens, similar to non-fungible tokens on other networks.
