Fungible token examples

Sui, a next-generation smart contract platform with high throughput, low latency, and an asset-oriented programming model powered by the Move programming language

BasicCoin

This project is a demonstration implementation of an ERC20-like fungible token built using the Move programming language. It showcases how Move's resource-oriented model and built-in security features can be applied to create secure digital asset contracts. The implementation serves as an educational example of Move's capabilities for blockchain development. ## Key Features - **ERC20 Compliance** — Implements the standard interface for fungible tokens including transfer, approval, and balance tracking functionality. - **Move Language Demonstration** — Illustrates Move's unique resource model where assets are treated as first-class citizens with built-in safety guarantees. - **Security-Focused Design** — Leverages Move's linear type system and absence of dynamic dispatch to prevent common smart contract vulnerabilities like reentrancy attacks. - **Educational Resource** — Provides a clear, minimal example for developers learning to write smart contracts in the Move language. ## Philosophy The project emphasizes Move's core philosophy of treating digital assets as resources with explicit ownership and transfer semantics, preventing accidental loss or duplication through compile-time guarantees.

Diem

0L is a blockchain platform forked from the Libra/Diem technologies, designed as a neutral replicated state machine. It inherits the advanced architecture of Diem while introducing critical changes for decentralization, including removal of the root account and a novel Sybil resistance mechanism called Delay Towers. ## Key Features - **Move Language** — A safe, ergonomic smart-contract language with built-in formal verification for adversarial environments. - **Decoupled Execution** — Parallel transaction processing for high throughput, leveraging Libra/Diem's execution layer. - **Delay Towers** — A Sybil resistance mechanism using sequential proofs of elapsed time instead of Proof-of-Stake. - **Hot Upgrades** — On-chain governance for synchronous, non-hard-fork network upgrades without operator intervention. - **Auto Pay** — Scheduled and recurring payment automation for donations, rewards, and community programs. - **Carpe Desktop App** — A combined wallet and light miner enabling desktop mining and coin creation for everyday users. ## Philosophy 0L aims to stay close to the Libra/Diem codebase to avoid fragmentation while layering on features for real-world, permissionless use, emphasizing decentralization and community-driven growth.
