A light Bitcoin block explorer without address indexing, using only a bitcoin core instance without RPC credentials (unauthenticated REST interface).
Runs live on mainnet, testnet and signet @ http://fbbe.info
Locally can run on regtest.
Supposing to have rust installed >= 1.66.0 and a synced bitcoin core on mainnet with txindex=1 and rest=1 do:
git clone https://github.com/RCasatta/fbbe
cd fbbe
cargo run --release
browse: http://localhost:3000/
After changing custom.css use a minifier:
yui-compressor custom.css > custom.min.css
There are 2 ways to build and run with docker, the standard way with a
Dockerfile is easier but produce a bigger docker image, the second one produce
a smaller image but requires nix.
docker build . -f ./docker/Dockerfile -t fbbe
docker run -it -p 3000:3000 -e BITCOIND_ADDR=172.17.0.1:8332 -e LOCAL_ADDR=0.0.0.0:3000 fbbe
nix --experimental-features 'nix-command flakes' build .#dockerImage
./result | docker load
docker run -it -p 3000:3000 -e BITCOIND_ADDR=172.17.0.1:8332 -e LOCAL_ADDR=0.0.0.0:3000 xenoky/fbbe:latest

To allow running the explorer on low-resource devices the memory usage must be kept low.
Better results with debug symbols even in release mode, if not already specified in Cargo.toml
use env var CARGO_PROFILE_RELEASE_DEBUG=true.
heaptrack works by tracking memory management syscall, after installing the tool use:
cargo build --release
timeout 10m heaptrack ./target/release/fbbe # in this example the tracker runs for 10 minutes
heaptrack_gui heaptrack.fbbe.105581.zst # file created by the previous command
