An Ethereum VM implementation

/*

This is the core of the Ethereum Virtual Machine (EVM or just VM).

NOTES:

stack items are lazily duplicated.
So you must never directly change a buffer from the stack,
instead you should `copy` it first

not all stack items are 32 bytes, so if the operation relies on the stack
item length then you must use utils.pad(<item>, 32) first.
