Sigilaris
A purely functional library for building application-specific private blockchains in Scala.
Overview
Sigilaris provides type-safe, deterministic building blocks for constructing custom blockchain applications. Built on the cats-effect ecosystem, it offers cross-platform support for both JVM and JavaScript, enabling you to create tailored blockchain solutions with compile-time guarantees.
Features
- Application-Specific Design: Build custom private blockchains tailored to your exact requirements
- Deterministic Encoding: Guaranteed consistent byte representation for hashing and signatures
- Purely Functional: Built on cats-effect for composable and referential transparent operations
- Cross-Platform: Supports both JVM and Scala.js
- Type-Safe: Leverages Scala's type system for compile-time safety
- Library-Agnostic: Flexible JSON codec works with any backend (Circe, Play JSON, etc.)

Core Modules
Data Types
Type-safe opaque types for blockchain primitives with built-in codec support.
- 한국어 문서 | English Documentation
- Includes: BigNat (arbitrary-precision naturals), UInt256 (256-bit unsigned), Utf8 (length-prefixed strings)
- Zero-cost abstractions with compile-time safety and automatic validation
Byte Codec
Deterministic byte encoding/decoding for custom blockchain implementations.
- 한국어 문서 | English Documentation
- Essential for: Transaction signing, block hashing, state commitment, consensus mechanisms
- Guarantees identical byte representation across all nodes
JSON Codec
Library-agnostic JSON encoding/decoding for blockchain APIs and configuration.
- 한국어 문서 | English Documentation
- Use cases: RPC API serialization, node configuration, off-chain data interchange
- Flexible backend support for seamless integration
