What Are the Key Economic Incentives for a Miner to Adopt a Soft Fork Upgrade?

The key economic incentives for a miner to adopt a soft fork upgrade are primarily maximizing revenue and avoiding block rejection. By adopting a popular soft fork, the miner ensures their blocks are considered valid by the majority of the network, guaranteeing they receive the block reward and transaction fees.

If they do not upgrade, their non-compliant blocks could be rejected by the upgraded majority, resulting in lost revenue and wasted hash power. Compliance is necessary to remain competitive and profitable.
