Make the explorer ONE Go binary fronted by github.com/hanzoai/zip (Fiber v3 /
fasthttp) that runs the Blockscout-rs Rust services IN-PROCESS via the existing
cgo FFI staticlib and reverse-proxies to each. Least-work: the Rust services are
not rewritten/ported — their real entrypoints run on Tokio threads inside the
process, keeping their own HTTP servers on loopback.
Front router (front.go): zip owns the public listener; routes in order
/api/<prefix>/* -> httputil.ReverseProxy -> 127.0.0.1:<svc_port> (prefix stripped)
/* -> the existing net/http explorer mux via zip.AdaptNetHTTP
Security headers + CORS become zip middleware (replaces withSecurity).
Config (services: block, ServicesConfig/resolveServices in config.go+services.go):
single source of truth for enabled services, loopback ports (base 8050,
HTTP=base+2n/gRPC=+1), URL prefixes, and per-service settings JSON; both the
proxy and the FFI launcher read it. startFFIServices now takes resolvedService
and feeds each service its server addr (+ DB url when set).
Status: sig-provider WIRED + PROVEN end-to-end — one process owns :8090 and
:8050, curl /api/sig/health -> {"status":"SERVING"} and the real REST API
/api/sig/api/v1/abi/function -> 200. visualizer + smart-contract-verifier are
stateless and ready to wire (recipe in ffi/README.md). stats +
multichain-aggregator stay DISABLED: blockscout-service-launcher's DB layer is
Postgres-only (initialize_postgres pins DatabaseBackend::Postgres) — no SQLite
without a Rust rewrite — and stats also needs a populated Blockscout indexer
Postgres. The Go side already passes database.url+migrations through, so they
enable with config alone once a Postgres exists.
Build: make single (cargo build ffi/ + go build -tags ffi) unchanged; default
go build ./... is the Go-native binary (ffi_off.go stub, no cgo). go build ./...
and go test ./... pass; make single links the sig-provider symbol and boots.
