Algorand (ALGO)

What Is Algorand?

Most blockchains decide who writes the next block by picking from a small, visible group of miners or validators. Algorand picks from everyone who is online, and it keeps the choice secret until the chosen accounts have already done their job. That idea came from Silvio Micali, an MIT cryptographer who shared the 2012 Turing Award for work on zero-knowledge proofs and probabilistic encryption.

Micali founded Algorand in 2017, and the mainnet launched in June 2019. The Algorand Foundation manages the token supply and ecosystem grants, while a separate company, Algorand Technologies, develops much of the core software. The network supports smart contracts, fungible tokens and NFTs, and transactions cost 0.001 ALGO.

The project set out to solve the blockchain trilemma, the idea that a network struggles to be decentralised, secure and fast at the same time. The mechanism it uses to attempt this, cryptographic sortition, is the part worth understanding in detail.

How Does Algorand Work?

Algorand’s version of proof-of-stake runs every round in three steps: propose, soft vote and certify. At each step, every online account runs a verifiable random function (VRF), a calculation that produces a random number only that account can generate but anyone can check afterwards. If the number falls below a threshold set by the account’s share of online stake, the account is selected for that step. It then publishes its block or vote together with a proof that it was chosen.

Two properties follow. Selection is private, so nobody knows who will propose or vote until the message is already on the network. Committees also change at every step, so an attacker who bribes or knocks out the proposer is too late, because the next step uses a fresh, unknown committee.

Consider an account holding 10,000 ALGO when 2 billion ALGO is online. That account owns 0.0005% of online stake, so it expects to be chosen in proportion to that share, about once every 200,000 selections.

Now consider an attacker who wants to certify a fraudulent block. Committees are drawn from all online stake, so the attacker needs to control roughly two-thirds of it to dominate a committee reliably. That is more than 1.3 billion ALGO. Buying that much would push the price up sharply, and a successful attack would destroy the value of the tokens the attacker just bought.

Once a certify committee signs a block, that block is final. There is no longest-chain rule and no waiting for confirmations, which is why applications can treat an Algorand payment as settled after a single block.

Algorand vs. Delegated Proof-of-Stake

In delegated proof-of-stake, token holders vote for a limited number of block producers, which makes those producers visible targets for pressure or attack. Algorand avoids a fixed producer set, but it pays for that with a different weakness: it relies on many ordinary holders actually running nodes.

Why Is Algorand Important for Traders?

ALGO is a case study in the gap between technical quality and market adoption. The network has run without a fork since launch, yet its share of DeFi activity has stayed small next to Ethereum and Solana. Developers and liquidity gather where other applications already live, so instant finality alone does not create demand for the token.

Participation incentives are the main structural weakness. For years, Algorand paid holders through a governance programme rather than for running nodes, so a large share of stake stayed offline, and a few large operators, including the foundation, carried much of the consensus load. In January 2025 the network began paying protocol rewards to accounts that run a node with at least 30,000 ALGO, an attempt to spread participation more widely.

Supply history matters as well. ALGO launched in June 2019 through a Dutch auction at $2.40 per token and lost more than 90% of that value within its first year, as scheduled releases pushed new tokens into a thin market. Traders comparing ALGO with newer layer-1 tokens can use that episode as a reminder that release schedules often set price direction in a token’s early years more than technology does.

Key Takeaways

• Algorand is a pure proof-of-stake blockchain in which any online ALGO holder can be selected to propose or vote, in proportion to their balance.
• Verifiable random functions keep selection secret until an account acts, and committees change at every step, which makes targeted attacks impractical.
• Blocks are final as soon as they are certified, so Algorand does not fork and needs no extra confirmations.
• ALGO has a fixed supply of 10 billion, pays fees and weights consensus participation, with no stake locking or slashing.
• Low node participation and limited DeFi adoption show that a technically fast chain still depends on incentives and developer activity.
