 machine, to run formally verified apps natively, making it as secure as
 mathematically possible. It also replaces expensive Merkle tree insertions by
-reversible heaps snapshots, greatly reducing the cost of SSTORE/SLOAD opcodes,

-as a massive simplification of Ethereum, with no native currency, greatly
