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?
Algorand’s decentralized Byzantine agreement protocol can tolerate an arbitrary number of malicious users as long as honest users hold a super majority of the total stake in the system. Two important features of the consensus protocol prevent powerful adversaries from corrupting enough users so as to control block generation:
First, the adversary does not know which users he should corrupt. In fact the users who are called to certify a new block are secretly and individually selected.
Second, when the adversary realizes which users are selected, it is too late for him to benefit from attacking them. Those users has already fulfilled their responsibility in the consensus protocol. In the next round of block certification, a new set of users will again be privately and individually chosen.
In Algorand, the power is in the hands of the users holding stake. Every user receives an amount of rewards proportional to their stake for every block that is committed to the chain. We do so to encourage users to join the Algorand platform and accelerate our path to decentralization.
Algorand is rooted in the idea that the system should allow for changes and avoid inflexible policies—enabling both the community and the protocol to evolve. The Algorand platform takes a consensus approach to protocol changes, which facilitates continuous evolution of the protocol and eliminates potential hard forks that could fracture the community. This ability is powered by the Algorand consensus protocol that enables the users to reach consensus on anything. Not just on the next block, but also on a protocol upgrade.
