A new proposal from the Zcash community suggests establishing a dynamic fee market to ensure users don't quit due to excessively high fees.

Shielded Labs has proposed a new proposal to create a dynamic fee market for Zcash to address rising transaction costs and network congestion. The proposal suggests abandoning Zcash's static fee model—initially 10,000 "zatoshi," later reduced to 1,000. While this model worked under low demand, it ultimately triggered a "sandblast" of spam transactions, causing wallet congestion and on-chain transaction blockage. Previously, ZIP-317 adopted an operation-based ledger, which addressed abuse issues, but fees remained predictable and low, unable to adjust based on usage.
