# ClockinChain Big Integer Specifications
This document collection contains the normative specifications for the ClockinChain Big Integer library, a production-ready big integer crate for blockchain consensus engines.
## Specifications
- [**Representation Specification v1.0**](representation.md) - Canonical encoding and memory layout
- [**Arithmetic Algorithm Specification v1.0**](arithmetic.md) - Deterministic arithmetic operations
- [**Montgomery & Modular Exponentiation Specification v1.0**](montgomery.md) - Cryptographic arithmetic
- [**Gas Schedule Specification v1.0**](gas.md) - Precomputable gas metering
## Overview
The ClockinChain Big Integer specifications define a complete cryptographic big integer arithmetic library with the following key properties:
- **Deterministic**: Bit-for-bit identical results across all platforms
- **Constant-time**: All operations execute in constant time to prevent timing attacks
- **Canonical encoding**: Unique representation for each integer value
- **Gas metering**: Precomputable gas costs for VM execution
- **Montgomery arithmetic**: Full support for cryptographic operations
- **Time-sliced operations**: Pausable long operations for async VM execution
## Implementation
These specifications are implemented in the [clock-bigint](https://github.com/olyntar-labs/clock-bigint) Rust crate.
