Bitcoin developers are debating the network’s future after the halvings.
They have once again raised the idea of removing the 21 million BTC cap.
The community is discussing scenarios after 2040.
linkA new debate has erupted in the Bitcoin developer community about the network’s long-term security as miner rewards gradually decline. The trigger was a large discussion thread on the Delving Bitcoin forum titled Addressing the Diminishing Block Subsidy, which drew the attention of the MARA Foundation.
Proposal: Permanent Issuance After 2040
The author of the discussion, under the pseudonym show1225, proposed introducing so-called tail emission — a small, permanent issuance after the block subsidy is significantly reduced.
According to the proposal:
Introduce an additional reward of 0.25 BTC per block
Activate the mechanism in 2040 at block height 1.68 million, when the reward drops from 0.390625 BTC to 0.1953125 BTC
Combine the new issuance with burning base fees, similar to EIP-1559 in Ethereum
The author calculated that this would result in issuance of about 13,140 BTC per year, or roughly 0.06% inflation, which could potentially be offset by fee burning during periods of high load.
