Overview

Constantinople is a high-throughput account-model blockchain example built on top of commonware primitives.

Primitive	Role
commonware-consensus (simplex)	Single-epoch BFT consensus with BLS threshold signatures
commonware-consensus (marshal)	Erasure-coded broadcast and backfill of finalized blocks
commonware-storage (QMDB)	Merkleized key-value database for state and transactions
commonware-glue (stateful)	Speculative state management and sync
commonware-p2p (discovery)	Authenticated peer-to-peer networking with discovery

Packages

Package	Description
constantinople-indexer	Publishes finalized block artifacts and SQL metadata to exoware.
constantinople-explorer	Streams indexer metadata into a live React block explorer.

Demo

Generate a local four-validator network with the indexer secondary, relayer, spammer, metadata indexer, QMDB indexer, and explorer:

cargo run --bin constantinople-deploy -- generate \
  --validators 4 \
  --indexer \
  --relayer \
  --output-dir ./local \
  --spammer --spammer-accounts 4096 --spammer-accounts-jitter 0.1 \
  local

The command prints an mprocs invocation that starts the generated local network. See bin/deploy/README.md for port and service details.
