Archivas is a Layer 1 blockchain that uses Proof-of-Space-and-Time (PoST) consensus - the same mechanism pioneered by Chia Network. Instead of wasting energy (PoW) or requiring capital lockup (PoS), Archivas secures its network with:

Disk Space (Proof-of-Space) - Farmers allocate storage to create "plots"

Sequential Time (VDF) - Timelords compute Verifiable Delay Functions
