Abstract
Various embodiments are generally directed to an apparatus, system, and other techniques for shared, trusted token generation for a token-bucket flow control policy implemented in a distributed ledger. Tokens may be generated by blocks in the distributed ledger, which may be a blockchain system. Trusted execution hardware may be used as a proof algorithm to ensure that a token exists, and that client has legitimately acquired or accumulated the token prior to using it to submit a transaction.
