+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+ibet-Core is the ibet Network node client, independently maintained from a GoQuorum fork. The Go module retains `github.com/ethereum/go-ethereum` as its import path.
+
+- `cmd/`: executable entry points, including `geth`, `bootnode`, and `abigen`.
+- `core/`, `consensus/`, `eth/`, `p2p/`, and `rpc/`: execution, consensus, networking, and APIs.
+- `private/`, `permission/`, `plugin/`, and `raft/`: inherited enterprise and permissioned-network features.
+- Package-local `*_test.go` files and `testdata/` directories contain tests and fixtures; `tests/` holds protocol tests and fuzzers.
+- `contracts/` contains contract sources; `docs/` contains operational documentation. `build/` contains build tooling; generated executables go to `build/bin/`.
+
+## Build, Test, and Development Commands
+
+Install Go 1.26.4 (matching `.go-version` and `go.mod`) and a C compiler. Run commands from the repository root.
+
+- `git submodule update --init --recursive`: fetch test fixtures under `tests/testdata`.
+- `make geth`: build the node as `build/bin/geth`.
+- `make all`: build all command-line utilities.
+- `./build/bin/geth --dev --datadir /tmp/ibet-core-dev console`: launch a local development node and console.
+- `make test`: build utilities, then run Go tests with package execution serialized.
+- `go test ./core/...`: run focused package tests.
+- `make format`: format Go source.
+- `make lint`: run the pinned golangci-lint tool using `.golangci.yml`.
+
+## Coding Style & Naming Conventions
+
+Use standard Go formatting with tab indentation and goimports-compatible imports. Keep package names lowercase, exported identifiers in PascalCase, and unexported identifiers in camelCase. Follow nearby code conventions and preserve upstream license headers. Update generators rather than hand-editing generated files.
+
+## Testing Guidelines
+
+Use Go's `testing` framework, naming files `*_test.go` and functions `TestXxx` or `BenchmarkXxx`. Add regression tests for behavior changes and keep fixtures in `testdata/`. Run focused tests during development and `make test` and `make lint` before submitting code. Use `go run build/ci.go test -race ./path/to/package` for concurrency changes. No numeric coverage threshold is configured.
+
+## Commit & Pull Request Guidelines
+
+Recent commits use concise imperative subjects such as `Fix Prague/Osaka precompile selection`; dependency updates use `chore(go)(deps): ...` or `chore(ci)(deps): ...`. Keep commits focused. PR descriptions should explain the problem, resulting behavior, related issues, and validation commands. Highlight consensus, fork-activation, configuration, or compatibility changes that affect node operators.

-This project is [GoQuorum](https://github.com/ConsenSys/quorum) fork for [ibet Network](https://github.com/BoostryJP/ibet-Network)
+ibet-Core is the node client for [ibet Network](https://github.com/BoostryJP/ibet-Network), developed from a [GoQuorum](https://github.com/ConsenSys/quorum) fork and maintained independently by BOOSTRY.
 
-## Version control policy
+## Overview
 
-This project is a fork of GoQuorum (and go-ethereum), and we decide which version of GoQuorum to adopt when developing each version and reflect those modules. 
-In addition, it has been modified to be optimal for the ibet Network.
+ibet-Core started as a fork of GoQuorum, which itself is based on go-ethereum. Since the fork, it has been developed independently for ibet Network rather than tracking new GoQuorum releases.
+It remains an EVM-compatible blockchain node client and selectively incorporates go-ethereum execution-layer improvements, dependency updates, and ibet Network-specific features needed for efficient and secure operation.
 
 The version control policy of this project follows that of ibet-Network.
 
-## Reference GoQuorum version
+## Features
 
-Currently, the ibet Network is built using a node client based on v24.4.0 of GoQuorum. 
-However, it has been variously patched to be optimized for ibet Network. For example:
+ibet-Core is developed on the GoQuorum baseline adopted by this project and includes the following enhancements:
 - The default block generation interval is set to 1 second.
-- Fully supports Go 1.25 and applies new 3rd party packages from a security perspective.
-- Made temporary fixes for bugs before they were fixed in the original GoQuorum.
+- Go 1.26 is supported, with third-party packages updated from a security perspective.
+- Selected go-ethereum execution-layer improvements are incorporated where they benefit ibet Network.
+- Project-specific fixes and operational improvements are maintained independently after the GoQuorum fork.
 - Added precompile for secp256r1 signature verification ([EIP-7951](https://eips.ethereum.org/EIPS/eip-7951)).
 - Added precompile for BLS12-381 curve operations ([EIP-2537](https://eips.ethereum.org/EIPS/eip-2537)).
 - Added support for AWS Secrets Manager / KMS based node key management.
