When a miner wins a block reward of Bitcoin, it’s issued an identical quantity of sustainable Bitcoin certificates (SBCs), which, like Bitcoin, are on-chain tokens divisible by 100 million. These tokens could be held or uncoupled from the Bitcoin coinbase and bought to institutional buyers and ESG-focused buyers, who can then match these to their Bitcoin holdings. Subsequent month, the protocol will perform its first end-to-end transaction from distribution of SBCs to a miner, to these being bought on to an ESG-focused investor, van Voorhees mentioned.
