When a miner wins a block reward of Bitcoin, it is issued a matching amount of sustainable Bitcoin certificates (SBCs), which, like Bitcoin, are on-chain tokens divisible by 100 million. These tokens can be held or uncoupled from the Bitcoin coinbase and sold to institutional investors and ESG-focused investors, who can then match these to their Bitcoin holdings. Next month, the protocol will carry out its first end-to-end transaction from distribution of SBCs to a miner, to those being sold on to an ESG-focused investor, van Voorhees said.
