## Block Reward Sustainability

Block reward sustainability refers to the ability of a blockchain to maintain its security model once the initial supply of tokens has been fully distributed. As block rewards decrease over time due to halvings, the network must transition toward a reliance on transaction fees to compensate validators.

If transaction volume is insufficient, the network may become vulnerable to security attacks due to low hash rate or low stake participation. Tail emissions are often implemented as a solution to bridge this gap, providing a baseline reward that ensures validators remain profitable.

This concept is essential for the long-term viability of proof-of-work and proof-of-stake systems. It forces a focus on creating high-utility networks that generate organic transaction demand.
