And how would i know about "Bytecode Virtual Machine/BVM" (since you're talking about technology for altcoin while this is Bitcoin Development & Technical Discussion section) ?
Why don't you share the whitepaper/technical article of this "Bytecode Virtual Machine" since just say "it's the most efficient way to process transactions" doesn't prove anything.

Frankly i don't believe it as Bitcoin transaction is very simple and use ECDSA which have fast verification speed, unless this BVM uses cryptography signature which have faster verification time than ECDSA.
Bitcoin also use merkle tree for it's block structure which is pretty fast
