Proof of Time (PoT) is a blockchain consensus method that verifies transactions based on how long a participant dedicates computing resources, rather than how much energy they use. It’s designed as a more sustainable alternative to Proof of Work (PoW), which requires powerful hardware and consumes large amounts of electricity.
Chia is the most well-known project using PoT, combining it with Proof of Space to create a system that’s energy-efficient and more accessible. Instead of solving complex puzzles as fast as possible, users participate by proving they’ve committed storage and waited a certain amount of time—making the process fairer, less wasteful, and open to more people.
By reducing energy demands and lowering entry barriers, PoT helps blockchains scale in a way that’s better for the environment without sacrificing security.
