Zebra siri ike Full Node
- Na-eji onye ọrụ na-enweghị ihe ùgwù + kernel-level systemd sandboxing (otu iche dị ka Docker).
- RPC bụ naanị localhost na nchekwa kuki (ndabara & akwadoro).
Ihe ndị a chọrọ
- ọ bụla Ubuntu dabeere distro
- Rust toolchain arụnyere (
rustup + cargo)
- Ọ dịkarịa ala 300 GB ohere disk (
