The Open Network (TON) is a blockchain project originally initiated by the team behind Telegram. It aims to provide a fast, secure, and scalable infrastructure for decentralized payments and services. TON employs a unique multi-layered blockchain architecture that enables high throughput, dynamic sharding, and robust cross-chain capabilities.
Unlike many traditional blockchains, TON is designed with flexibility and performance in mind. Its structure includes a masterchain, workchains, and shardchains, allowing it to scale almost infinitely based on network demand. Combined with its innovative consensus mechanism and smart contract features, TON represents a significant evolution in blockchain technology.
Understanding TON’s Architecture
TON’s architecture is built around a hierarchical structure that supports horizontal scaling. This design allows the network to process millions of transactions per second while maintaining security and decentralization.
At the highest level is the Masterchain, which handles network-wide synchronization and governance. It tracks global state changes and ensures consensus across all components.
Below the Masterchain are Workchains, which are responsible for executing smart contracts. Each Workchain can be customized with its own rules and virtual machines, offering flexibility for different use cases.
Each Workchain is further divided into Shardchains. These are smaller chains that process transactions in parallel. Shardchains can be split or merged dynamically based on network load, ensuring optimal performance.
At the lowest level are Accountchains, which manage user accounts and transaction histories. This layered approach allows TON to achieve high throughput without sacrificing security.
Consensus Mechanism: Catchain
TON uses a unique consensus algorithm called Catchain (Catalyzed Chain). It is a Byzantine Fault Tolerant (BFT) proof-of-stake (PoS) mechanism that enables fast block finality.
In Catchain, validators take turns proposing and validating blocks. The network can tolerate up to one-third of validators acting maliciously without compromising security. Blocks are validated as they are created, reducing the need for reorganizations or forks.
This mechanism allows TON to achieve block times as low as 5 seconds, making it one of the fastest blockchain networks available today.
Smart Contracts on TON
TON supports smart contracts but takes a different approach compared to platforms like Ethereum. Instead of using complex programming languages like Solidity, TON uses Fift, a simplified language designed for security and efficiency.
Key features of TON’s smart contracts include:
- State Machine Model: Contracts are based on a state machine, ensuring atomic state changes and preventing reentrancy attacks.
- Asynchronous Messaging: Contracts communicate via non-blocking messages, improving throughput and interoperability.
- Cross-Chain Calls: Contracts can call functions on other workchains, enabling seamless cross-chain applications.
- Unlimited Computation: Unlike Ethereum, TON does not impose gas limits on loops, allowing for more complex computations.
- Automatic Memory Management: A built-in garbage collection mechanism eliminates manual memory management.
These features make TON’s smart contracts more flexible and scalable, suitable for high-performance decentralized applications.
Cross-Chain Transactions with Two-Phase Commit (2PC)
TON uses an optimized version of the Two-Phase Commit (2PC) protocol to handle cross-chain transactions. This ensures consistency and reliability when moving assets between different shards or workchains.
The process involves:
- Initialization: The sender chain locks assets and sends a prepare request to the receiver chain.
- Preparation: The receiver chain validates the request and prepares to accept the assets.
- Commit: If preparation is successful, the sender chain finalizes the transfer and notifies the receiver.
- Confirmation: The receiver completes the transfer and sends a confirmation back.
To handle failures, TON introduces timeouts, retry mechanisms, and rollback capabilities. These optimizations make cross-chain transactions on TON both fast and secure.
Proxy Layer for Decentralized Services
TON includes a proxy layer that provides decentralized services such as domain name resolution, storage, and payment processing. This layer acts as a bridge between applications and the underlying blockchain, simplifying development and improving user experience.
Services in the proxy layer are implemented as smart contracts, inheriting the security and transparency of the blockchain. They are designed to be modular and interoperable, allowing developers to mix and match functionalities as needed.
TON Tokenomics
The native token of TON is called TON Coin. Initially, the total supply was 5 billion tokens, with 1.45% allocated to the team and the rest distributed via proof-of-work (PoW) mining. The network has since transitioned to proof-of-stake (PoS), with an annual inflation rate of approximately 0.6%.
In 2023, a proposal was passed to freeze inactive wallets for 48 months. These wallets had no transaction history and held over 1.081 billion TON tokens, about 21% of the supply at the time.
