Quick Chain

Quick Chain is a high-performance blockchain designed for fast block production and can be used as a distributed database.
It provides low-latency consensus, flexible data storage, and scalable architecture suitable for both financial and non-financial applications.

---

🚀 Features

• ⚡ Fast Block Production — sub-second block times, optimized for low-latency use cases.
• 📦 Distributed Database — store structured or unstructured data on-chain with high availability.
• 🔒 Secure Consensus — Byzantine Fault Tolerant consensus ensuring data consistency across nodes.
• 🌐 Scalable Network — horizontally scalable node architecture.
• 🔧 Developer Friendly — gRPC/REST APIs, SDKs, and CLI tools for easy integration.

⚙️ Getting Started

1. Clone the Repository

git clone https://github.com/your-org/quickChain.git
cd quickChain

2. Run Guide (start CometBFT first)

# Install CometBFT
go install github.com/cometbft/cometbft/cmd/cometbft@v1.0.1

# Initialize a local node (once)
$(go env GOPATH)/bin/cometbft init

# Terminal A: start CometBFT (defaults to proxy_app tcp://127.0.0.1:26658)
$(go env GOPATH)/bin/cometbft start

# Terminal B: run the ABCI app (CounterApp)
go run ./cmd/quickchaincli

# Terminal C: send a few transactions via RPC
curl -s "http://localhost:26657/broadcast_tx_commit?tx=\"tx1\"" > /dev/null
curl -s "http://localhost:26657/broadcast_tx_commit?tx=\"tx2\"" > /dev/null
curl -s "http://localhost:26657/broadcast_tx_commit?tx=\"tx3\"" > /dev/null

# Query current count (base64 -> text)
curl -s "http://localhost:26657/abci_query?data=0x00" \
| jq -r '.result.response.value' | base64 --decode; echo

# (Optional) send 1000 tx sequentially (zsh/bash)
for i in {1..1000}; do curl -s "http://localhost:26657/broadcast_tx_commit?tx=\"tx$i\"" > /dev/null; done

# (Optional) send 1000 tx with concurrency 20
seq 1 1000 | xargs -P 20 -I{} sh -c 'curl -s "http://localhost:26657/broadcast_tx_commit?tx=\"tx{}\"" > /dev/null'

📖 Example Use Cases

• Financial applications: low-latency payment settlement
• Gaming: real-time asset tracking and state synchronization
• IoT / Edge: distributed data collection with fault tolerance
• Enterprise: decentralized log or record management

---

🔮 Roadmap

• Add WebAssembly (Wasm) smart contract support
• Cross-chain interoperability
• Sharding for horizontal scalability
• Advanced query language for on-chain data
