Fae: a functional alternative to Ethereum
Fae is a smart contract system and blockchain definition with equivalent power to Ethereum but with the following additional benefits:
-
It is inherently scalable in that a participant's storage requirements need not grow at the same speed as the blockchain.
-
Smart contracts are immutable and stateless, preventing errors of reentrancy.
-
Immutability and statelessness equate to a UTXO-based blockchain.
-
There is no virtual machine, but rather a minimal execution environment that can run an existing, general-purpose programming language.
-
There is no native currency, only a simple token awarded to the participants that mine blocks.
-
Scarcity policy is left to the discretion of each smart contract.
We provide a formal specification of the system and an implementation in Haskell.
