This BIP proposes a consensus rule update t= o implement a strict circular economy within the Bitcoin network, keeping t= he 21 million maximum supply limit permanently intact.

An expira= tion limit is introduced for Unspent Transaction Outputs (UTXOs).

The nominal value of these expired satoshis will not be in= jected into immediate block rewards. Instead, they will be reintroduced int= o the pending emission reserve, dynamically extending the duration of halvi= ng epochs to guarantee a perpetual block subsidy without adding inflation.<= br />
