When authorizing an agent to execute an operation, two fundamentally different architectural choices exist: single-agent authorization lets one agent independently hold complete authority to sign a transaction, with any operation executing once that one agent alone agrees; multisig authorization requires a certain threshold number of multiple independent agents (or a combination of agents and humans) to all agree before an operation executes. The two architectures have a fundamentally different actual consequence when a single link goes wrong.

Whether a <a href="/en/glossary/commodities/carbon-credit/">Carbon Credit</a> is legitimate hinges on a counterfactual question: would this emission reduction or removal have happened anyway without the revenue from selling the credit?

A tradeable certificate representing one tonne of carbon dioxide equivalent (tCO₂e) of emission reduction or carbon removal. Companies buy carbon credits to 'offset' emissions they can't directly reduce, claiming carbon neutrality. Tokenized carbon credits (like Toucan Protocol's BCT, Moss.Earth's MCO2) move these certificates on-chain, making carbon markets more transparent and preventing double-counting — but underlying <a href="/en/glossary/commodities/carbon-credit/" target="_blank">Carbon Credit</a> quality remains the market's biggest controversy.
