Algorand

Algorand (ALGO) is a blockchain network that serves as a digital currency and a smart contract platform. It is built to be scalable, secure and decentralized. The network reaches agreement on new blocks through a variant of proof-of-stake called Pure Proof-of-Stake.

Developers can create decentralized applications with familiar programming languages, and Python is supported natively. A toolkit named AlgoKit is provided to support the development workflow. The protocol allows assets to be tokenized and smart contracts to be deployed. It is aimed at both individual users who need basic transactions and enterprises with more complex requirements.

Documented use cases include payment systems, digital identity, supply-chain tracking and financial services. The project also points to tokenized real-world assets and decentralized finance, where it cites instant settlement and atomic execution. It describes its low-cost settlement layer as suited to AI agents that transact automatically.

Algorand has worked on quantum resistance through Falcon signatures, which it has used since 2022 to protect the history of its chain. In 2025 it carried out a quantum-resistant transaction on Mainnet, and in 2026 it released native post-quantum accounts.
