What Is Algorand (ALGO)? A Beginner’s Guide

Algorand is a public, permissionless Layer 1 blockchain built for payments, digital assets, and applications. ALGO is its native coin. The network uses a consensus model called Pure Proof of Stake, which randomly selects block producers in proportion to the ALGO they keep online, so it requires no mining or locked deposits. Blocks arrive roughly every three seconds, and once a block is certified, its transactions are final.

This guide explains what Algorand is, who created it, how its consensus works, what ALGO is used for, what it costs to use the network, and the risks you should understand before you buy, hold, or build on it.

What Is Algorand (ALGO)?

Algorand is a blockchain platform: a shared ledger that thousands of computers keep in sync without a central operator. Anyone can create an account, send transactions, issue tokens, or deploy smart contracts. No one needs permission to join.

The network has one native asset, the ALGO coin. You need it to pay transaction fees, keep an account active, and participate in consensus. Every other token on Algorand, from stablecoins to NFTs, is an Algorand Standard Asset (ASA) issued on top of the protocol.

Three design choices set Algorand apart:

• Pure Proof of Stake (PPoS). Consensus influence depends on how much ALGO an account brings online. There is no proof-of-work mining.
• Random committee selection. Each round, the protocol secretly and randomly picks who proposes a block and who votes on it.
• Immediate finality. A transaction in a certified block does not get reversed by a later chain reorganization.

Who Created Algorand?

Silvio Micali, a cryptographer and MIT professor, founded Algorand in 2017. Micali received the Turing Award in 2012 for his work in cryptography, including zero-knowledge proofs and verifiable random functions. That second concept sits at the center of how Algorand selects block producers.

The Algorand mainnet and the ALGO coin went live in June 2019. Today, two organizations support the network: the Algorand Foundation, which manages the ecosystem treasury, governance, and grants, and Algorand Technologies, the company behind much of the core protocol development. The protocol code is open source, and anyone can run a node.

How Does Algorand Work?

Algorand reaches agreement on new blocks through Pure Proof of Stake. Here is the basic idea.

Any account holding ALGO can register as an “online” account. To do that, the owner generates participation keys on a node and signs a transaction that links those keys to the account. Participation keys are special credentials used only for consensus. They can sign votes and block proposals, but they cannot spend the account’s funds.

For every round, the protocol runs cryptographic sortition, a lottery that uses a verifiable random function (VRF). A VRF is a cryptographic method that produces a random-looking output and a proof anyone can verify. Each online account runs the lottery privately using its own keys. If it wins, it gets a proof of selection it can show to the rest of the network.

The more online stake an account has, the higher its chance of selection. On average, an account with 2% of the online stake will be chosen about twice as often as one with 1%.

Sortition fills two roles in each round:

• Block proposers assemble a candidate block from pending transactions and broadcast it.
• Voting committees review the proposals and vote on which block to accept.

Because selection happens privately, nobody knows who will propose or vote until those accounts reveal their proofs. By then, they have already sent their message. An attacker cannot target the next committee in advance, and a new committee is chosen for each step.

Your ALGO stays in your account the whole time. PPoS doesn’t lock coins, and there is no slashing (an automatic penalty that destroys part of a validator’s stake). You can spend ALGO from an online account anytime. Your consensus weight simply follows your balance.

How a Transaction Becomes Final

Here is what happens when you send ALGO to a friend:

1. Your wallet signs the transaction and sends it to a node.
2. The node checks it and passes it across the network.
3. A selected block proposer includes the transaction in a candidate block.
4. Voting committees run through a few rounds of voting until a supermajority agrees on one block.
5. The block is certified and added to the ledger.

Once step five is done, the transaction is final. On Bitcoin, exchanges often wait for several more blocks because a competing chain could replace recent ones. Algorand’s consensus design does not produce competing forks under normal operation, so users do not need to wait for extra confirmations. Rounds currently take about 2.8 seconds on average, which means a payment typically settles in under three seconds.

This finality is a property of the protocol under its security assumptions. The main one is that an honest supermajority of the online stake, more than two-thirds, follows the rules. If that assumption broke, the guarantees would no longer hold. That has not happened, but “final” here describes how the protocol is designed, not a promise against every possible failure.

Validator Nodes, Repeater Nodes, and Network Routing

Algorand nodes take on different roles:

• Validator nodes (also called participation nodes) hold participation keys for one or more online accounts. They propose blocks and vote when the network selects their accounts. They do not need to store the full ledger history.
• Repeater nodes (historically called relay nodes) handle networking. They pass transactions, blocks, and votes between validators so messages spread quickly across the globe.
• Archival nodes store the complete history of the chain for explorers, indexers, and new nodes catching up.

In the classic setup, validators connect only to repeaters, and repeaters connect to each other. This hub-like design keeps message delay low, but it also relied on a relatively small set of relay operators. Algorand has been moving to a peer-to-peer gossip network where validators can discover repeaters on their own, and repeaters are permissionless, reducing that dependence.

What Is ALGO Used For?

ALGO is a utility coin with three main jobs on the network.

Transaction Fees and Minimum Balances

Every transaction on Algorand pays a fee in ALGO. That includes ALGO payments, ASA transfers, and smart contract calls. The fee goes to a protocol account called the fee sink, and part of it now goes to block proposers as a reward.

Every account must also hold a minimum balance. A basic account must keep at least 0.1 ALGO. This requirement works as a deposit for the space your account takes up on the ledger, and it rises as you store more data. You’ll find the exact figures in the cost section below.

Consensus Participation and Rewards

ALGO weights an online account’s participation in consensus. More ALGO online means more chances to propose blocks and serve on voting committees, so the network’s security depends on that holder behaving honestly.

Since early 2025, Algorand pays protocol staking rewards to eligible block proposers. More on how that works below.

Supply and Circulation

The maximum supply of ALGO is 10 billion coins, all created when the network launched in 2019. No new ALGO will ever be minted.

The circulating supply is below 10 billion because the foundation and ecosystem wallets have gradually released part of the original allocation over time. That number keeps changing, so check a live source, such as the Algorand Foundation’s transparency reports or a market data site, and note the date before relying on it.

What Does It Cost to Use Algorand?

Algorand is cheap to use, though “cheap” has a few moving parts:

Cost item	Amount	Notes
Base transaction fee	0.001 ALGO	Typical fee when the network is not congested
Account minimum balance	0.1 ALGO	Required for any account to exist on-chain
Each ASA held or created	+0.1 ALGO	Added to the account’s minimum balance
Each app opted into or created	+0.1 ALGO and up	Grows with the amount of on-chain storage

The 0.001 ALGO base fee applies to almost every transaction, whether it’s a simple payment or a smart contract call. It is the minimum, not a fixed price. If the network gets congested, fees can rise based on transaction size, and some smart contract calls pay extra to cover additional work.

The minimum balance is not spent. It stays in your account and frees up when you remove the data. For example, if you opt out of an ASA, your minimum balance drops by 0.1 ALGO. Any transaction that would push your balance below the minimum will fail, which is a common surprise for new users.

What Can People Build on Algorand?

Algorand does more than move ALGO from one wallet to another. Developers use it to issue tokens and run on-chain programs.

Create and Receive Algorand Standard Assets

Algorand Standard Assets are tokens created through the protocol itself, not a separate smart contract. That makes them different from Ethereum‘s ERC-20 tokens, which each live inside their own contract.

ASAs can represent:

• fungible tokens, such as stablecoins (USDC runs on Algorand as an ASA), loyalty points, or in-game currencies;
• unique assets, such as NFTs, certificates, or tokenized real-world items.

Issuers can set optional controls, including the ability to freeze or claw back tokens. These are useful for regulated assets but worth checking before you buy a token.

To receive an ASA, an account generally has to opt in first. Opting in means sending yourself a zero-amount transfer of that asset, which tells the network you agree to hold it. This blocks spam tokens from landing in your wallet, but it also means a transfer will fail if the recipient hasn’t opted in. Each opt-in raises your minimum balance by 0.1 ALGO.

Use Smart Contract Applications

Smart contracts on Algorand are called applications. Developers write them in high-level languages such as Algorand Python or Algorand TypeScript, which compile down to TEAL, the network’s low-level programming language. The Algorand Virtual Machine (AVM) then runs that compiled code on every node.

Users interact with an application by sending it a transaction. Some applications also require an opt-in if they store data in your account.

Common uses include decentralized exchanges, lending protocols, staking pools, NFT marketplaces, and tokenization platforms. Algorand also supports atomic transfers, which bundle up to 16 transactions so they all succeed or all fail together. That makes trades between two parties safer, since one side can’t receive assets without the other side paying.

Can You Earn Rewards by Holding or Staking ALGO?

Yes, but not just by holding ALGO in a wallet. You need to take part in consensus.

Algorand introduced protocol staking rewards with the Algorand 4.0 upgrade in January 2025. When an eligible online account proposes a block that the network accepts, it receives:

• a share of the transaction fees in that block (currently 50%);
• a bonus funded by the Algorand Foundation, which started at 10 ALGO per block and shrinks by 1% every million blocks over a planned period of roughly two years.

To qualify for these protocol rewards, an individual account must have at least 30,000 ALGO online. Anyone can still run a validator and participate in consensus with much less, even a small amount, but accounts below the threshold don’t earn protocol rewards.

Holders with less than 30,000 ALGO can join third-party staking pools or liquid staking services. These combine deposits from many users to meet the threshold and then share the rewards. Each service has its own terms, fees, and smart contract risks, so they work differently from solo staking.

The older Algorand governance rewards program, where holders earned ALGO for committing coins and voting, ended in 2025. The final rewarded period closed on March 31, 2025. Governance votes continue, but they no longer pay rewards.

Reward amounts depend on your stake, how often your account is selected, network fee volume, and the declining foundation bonus. Treat any APY figure you see as an estimate, not a fixed rate.

How Is Algorand Different From Bitcoin and Ethereum?

Feature	Bitcoin	Ethereum	Algorand
Consensus	Proof of work (mining)	Proof of stake (validators)	Pure Proof of Stake
Typical block time	About 10 minutes	12 seconds	About 2.8 seconds
Finality	Probabilistic; users often wait 6 blocks	Final after about 13 minutes	Immediate once a block is certified
Staking requirement	Not applicable	32 ETH per solo validator, locked	No lock-up; 30,000 ALGO for protocol rewards
Slashing	No	Yes	No
Supply cap	21 million BTC	No fixed cap	10 billion ALGO
Tokens	Limited native support	ERC-20 smart contracts	Built-in ASAs

Bitcoin secures its ledger by burning electricity through mining. It focuses on being a store of value and has a deliberately limited scripting system. Algorand uses far less energy and supports tokens and full smart contracts out of the box.

Ethereum also uses proof of stake, but its validators must lock 32 ETH and risk slashing for misbehavior. Ethereum has a much larger developer community and more decentralized applications. Algorand offers faster settlement, lower and more predictable fees, and native tokens that don’t depend on individual contract code.

What Are Algorand’s Limitations and Risks?

No blockchain is free of trade-offs. Here are the main ones for Algorand.

Protocol and Network Trade-Offs

• Security assumptions. Algorand’s finality depends on more than two-thirds of the online stake being honest. If a single party or coalition controlled enough online stake, it could disrupt consensus.
• Stake concentration. Consensus weight follows ALGO balances. Large holders, including foundation wallets and exchanges, can carry significant influence if they bring their coins online.
• Network architecture. For years, Algorand relied on a fairly small set of relay operators. The move to a peer-to-peer network addresses this, but how decentralized that layer becomes in practice is still worth watching.
• Ecosystem size. Algorand’s DeFi and app ecosystem is smaller than Ethereum’s or Solana‘s. That can mean thinner liquidity and fewer tools.
• Rewards funding. Part of the current staking rewards comes from a foundation-funded bonus that shrinks over time. Over the long run, rewards will rely more on transaction fees.

Risks for Users

• Price volatility. ALGO’s price can swing sharply. Like other cryptocurrencies, it can lose a large share of its value quickly.
• Changing circulating supply. As more of the 10 billion ALGO enters circulation, the added supply can put pressure on the price.
• Opt-in and minimum balance mistakes. Sending an ASA to an account that hasn’t opted in will fail, and dropping below the minimum balance blocks transactions. Neither loses funds, but both confuse new users.
• Fake tokens. Anyone can create an ASA with any name. Always check the asset ID, not just the ticker, before buying or opting in.
• Smart contract and staking pool risk. Bugs, exploits, or poor management in third-party apps and pools can lead to losses. The protocol itself doesn’t slash stake, but a pool’s contract can still fail.
• Key management. If you lose your recovery phrase, nobody can restore your ALGO. Store it offline and never share it.
• Regulation. Rules on crypto assets, staking services, and token issuance differ by country and keep changing.

Final Words

Algorand is a Layer 1 blockchain Silvio Micali designed to settle transactions in seconds with immediate finality. Its Pure Proof of Stake model uses verifiable random functions to select block proposers and voting committees, keeps ALGO liquid while securing the network, and avoids mining’s energy cost. ALGO pays transaction fees, covers minimum balances, and weights each online account’s say in consensus. Holders with 30,000 ALGO or more can earn protocol rewards directly.

The network also has clear limits: a smaller ecosystem than the largest chains, rewards that partly depend on a shrinking foundation bonus, and the usual price swings of any crypto asset. Read up on the opt-in system and minimum balance before you start, and check asset IDs before accepting tokens.
