Six blockchain organizations jointly submitted a comment letter asking the U.S. Securities and Exchange Commission to explicitly define digital commodities and clarify their non-security status in proposed rules. The organizations are Stellar Development Foundation, Hedera, Aptos Labs, Ava Labs, Cardano Foundation and Chainlink Labs. The definition currently appears only in the proposed rules' preamble, not in the binding rule text. The organizations believe codification would reduce regulatory uncertainty and provide a more stable legal framework for public blockchain developers and ecosystem participants.
