Block Reward Subsidy
A block reward subsidy is the portion of newly minted tokens awarded to validators or miners for successfully verifying a block of transactions and adding it to the blockchain. This subsidy serves as the primary incentive for participants to secure the network and process transactions in a decentralized manner.
In the early stages of a project, this subsidy is often high to encourage participation and network growth, but it typically decreases over time as transaction fees become the primary source of revenue for network maintainers. The block reward acts as a security budget, representing the cost the network is willing to pay to maintain its integrity and immutability.
Understanding the subsidy trajectory is essential for evaluating the long-term viability of a consensus mechanism.
