Introduction

Introduction

Welcome to Tessera, a Python implementation of JAM (Join Accumulate Machine). Tessera is designed to provide a performant, type-safe, and scalable blockchain infrastructure with a focus on user-friendly interfaces and developer experience.

Key Features

• Type-safe Serialization: Custom codec system for handling protocol types
• Consensus Mechanisms: Implementation of Safrole and GRANDPA protocols
• State Transition Functions: Efficient state transitions
• Network Layer: P2P communication with async I/O
• Execution Environment: Polkadot Virtual Machine (PVM) for generic smart contracts

Architecture Overview

Tessera is built with a modular architecture:

• Core Protocol: Implements the JAM protocol specification
• State Layer: Manages blockchain state and transitions
• Consensus Layer: Handles block production and finality
• Network Layer: Manages peer connections and data sync
• Execution Layer: Runs the Polkadot Virtual Machine (PVM)

Development Status

Tessera is currently under active development. While core components are functional, some features are still being implemented and the API may change.
