What we do / Technology

Technology

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 permissionless 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.

The era of a decentralized, borderless economy is here. Algorand is the foundation. Now what will you build?

DECENTRALIZATION

The Algorand blockchain is entirely decentralized, which means there is no powerful central authority or single point of control. A unique committee of users is randomly and secretly selected to approve every block. Nodes are run by entities representing diverse backgrounds across many different countries.

Fair & Transparent

Control is distributed among all individual network participants

Accurate

No risk of data being manipulated, lost or destroyed

Secure

Fault tolerant with no special group of users for an attacker to target

Permissionless

Public & Open to All

Users do not need the approval of a trusted authority to use the Algorand blockchain. There is a single class of users and no gatekeepers. Every participant can read every block and have the opportunity to write a transaction in a future block.

Low Cost to Participate

The Algorand platform requires minimal processing power and modest IT resources to join. All online users who possess algos are automatically eligible to participate in block consensus.

Open Source

The Algorand node repository is open sourced and publicly available for anyone to audit, use, and build upon. The platform is founded in principles of transparency, inclusivity, and collaboration and maintained by a dedicated community with a shared vision of a decentralized, borderless future.

Network-Level Security: Partition Resilience

The Algorand protocol is secure against an adversary who may achieve complete control over the network and dictate which users receive which messages and when. Even when the network is partitioned into multiple non-connected networks, Algorand’s blockchain does not fork and users’ balances remain secure. An adversary is never able to convince two honest users to accept two different blocks for the same round. All transactions that appear on the blockchain are always final. Algorand is able to recover after a partition is resolved and guarantees that new blocks will be generated at the same speed as before the partition.

Scalability

  • No computation resources wasted solving cryptographic puzzles
  • Only a small subset of users selected to participate each time a new block is generated
  • Number of selected users doesn’t change as the total number of network users increases
  • Users do not need to communicate with others to determine whether they’re selected
  • Total communication cost of the network scales linearly
  • Blocks typically finalize within seconds
