rbpf

Solana uses a custom Rust re-implementation of a custom C re-implementation of the Linux BPF VM for what appears to be licensing reasons. Notably, it's jitting all bytecode without a verifier or emitting runtime bounds checks[0]. I suspect you can pop a shell on every single computer on their testnet somewhere between "trivially" and "extremely trivially". They appear to be running some kind of "open security test"[1] but are only paying out their own imaginary funny money. I'd suggest you run for the hills as fast as you can instead of considering Solana. 0: https://github.com/solana-labs/rbpf/blob/f7007d6ae8728e61401... 1: https://forums.solana.com/t/tour-de-sol-stage-1-details/317

eBPF is also used high throughput blockchain, Solana https://github.com/solana-labs/rbpf Unlike more common Rust + LLVM + WASM toolchain, Solana smart contracts use Rust + LLVM + eBPF.
