Why Is Having a Cost to Fork the Chain Important for Financial Stability?

A cost to fork the chain ensures that creating an alternative, competing history of transactions is economically prohibitive. Without this cost, malicious actors could easily create forks to attempt double-spending or rollback transactions.

This prevents instability and maintains the immutability and finality of the ledger. Financial stability, especially for derivatives and settlement, relies on the certainty of past transactions.
