## Post-Halving Security Sustainability

Post-halving security sustainability refers to the challenge of maintaining network security after the programmed reduction in block rewards. As the supply of new tokens decreases, the protocol must ensure that transaction fees or other revenue streams grow sufficiently to maintain the same level of security.

If this transition fails, the security budget could collapse, leading to increased susceptibility to chain reorganization attacks. This concept is central to the fundamental value proposition of store-of-value assets, as the network must remain immutable even when the subsidy is minimal.

Developers must model various scenarios, including transaction volume growth and price appreciation, to ensure the protocol remains robust. It is a critical metric for long-term investors evaluating the viability of a blockchain's economic design.

Successful protocols often shift their security model from reliance on inflation to reliance on genuine network utility.
