Avalanche activates Helicon upgrade, enhancing staking and execution

Avalanche flipped the switch on Helicon, the network’s most substantial staking overhaul to date, going live on Mainnet on September 22 at 11:00 AM ET. The upgrade rolls six community proposals into a single AvalancheGo v1.15.0 release, touching everything from how validators earn rewards to how the C-Chain processes transactions. What Helicon actually changes The minimum lock-up period drops from 336 hours (14 days) to just 48 hours (two days). That’s a sevenfold reduction in the shortest commitment a validator needs to make. Auto-renewed staking is the second big change. Previously, validators had to manually re-stake their AVAX once a staking period expired. Auto-renewal eliminates that overhead entirely. Stakes now roll over unless a validator explicitly opts out. The uptime requirement for validator rewards jumps from 80% to 90% for new staking periods.

The new curve is designed to reward longer staking commitments more generously while tightening payouts for short-duration stakers. The projected net effect ...
