Zcash Developers Push for Faster 20-Second Blocks After Recent Upgrade
Zcash's development team is proposing 20-second block times, building on a recent speed upgrade to boost network throughput.
The team behind Zcash, the privacy-focused cryptocurrency, is already eyeing its next performance leap just days after completing a significant network speed upgrade. Developers are now proposing a reduction in block times to 20 seconds, a move that would substantially increase how quickly transactions are confirmed on the blockchain.
Block time — the interval at which new batches of transactions are permanently recorded — is a core lever in blockchain performance engineering. Shorter block times generally mean faster confirmations for users and greater overall throughput for the network, though they also introduce technical tradeoffs around consensus stability and node synchronization that engineers must carefully manage.

The timing of this proposal is notable. By pushing for another round of improvements so soon after the previous upgrade, Zcash's developers signal a sustained commitment to making the network more competitive with faster chains. Privacy-preserving blockchains have historically lagged behind in raw speed, and closing that gap could be critical to broadening Zcash's real-world utility and user adoption.
Whether the community ultimately approves a shift to 20-second blocks will depend on technical review and governance processes, but the proposal itself reflects a broader trend across the crypto landscape: established networks continuously iterating on their base-layer performance rather than treating early design choices as permanent constraints.
