# Upcoming Changes to Block Time Targets

Understandably, this variable rate of token emission is concerning, and we have put some thought into various alternatives. While we considered time-based proration, we were concerned that the incentives there were not particularly good, as anyone who wanted to minimize work while maximizing return would simply do what they could to slow times down by interfering with the consensus group. The strategy we have eventually settled on is a deterministic speedup. Typically, the next target block time is calculated by taking the time of the last block and adding a chain variable called block_time, which is currently 60000ms. If that time is in the past, we start immediately.
