Algorand removes the technical barriers that for years undermined mainstream blockchain adoption: decentralization, scale, and security. Now you can build on a stable platform you trust.

Our consensus mechanism is permission less and PURE PROOF OF STAKE™. It ensures full participation, protection, and speed within a truly decentralized network. With blocks finalized in seconds, Algorand’s transaction throughput is on par with large payment and financial networks. And Algorand is the first blockchain to provide immediate transaction finality. No forking. No uncertainty. Algorand uses cryptographic sortition to select users to propose blocks for a given round. When a block is proposed to the blockchain, a committee of voters is selected to vote on the block proposal. If a super majority of the votes are from honest participants, the block can be certified.


The Algorand blockchain uses a decentralized Byzantine agreement protocol based on pure proof-of-stake (PPoS). It can tolerate an arbitrary number of malicious users as long as honest users (those that follow the instructions of the protocol) hold more than two-thirds of the total stake in the system.
