About EvaporChain
EvaporChain is a Layer 1 blockchain research project exploring thermodynamic state decay: the idea that blockchain data should have a natural lifespan.
The Problem
Every blockchain ever built has the same problem: state grows forever. Ethereum's state is over 200 GB and climbing. Old smart contracts, abandoned NFTs, and empty accounts sit in the ledger permanently, making the network heavier and more expensive to run over time.
The Idea
What if state objects carried energy that depleted over time? When an object's energy reaches zero, it evaporates from the active ledger. It leaves behind a compact cryptographic proof (a “ghost record”) that permanently verifies the data existed. The result is a blockchain that gets lighter over time, not heavier.
Where We Are
The testnet is live with a working implementation across 16 Rust crates and 4,668+ passing tests. The core engine handles object creation, energy decay, evaporation, ghost proofs, resurrection, NFTs (EVR-721), fungible tokens (EVR-20), staking, and on-chain governance. All signatures use post-quantum ML-DSA cryptography.
