What is Aleo?

Aleo is a layer 1 blockchain, live since September 2024, built around zero-knowledge proofs. Programs run on the user's own device and only a proof goes on-chain, so balances and other data can be stored as encrypted records instead of public entries. ALEO pays fees, is staked with validators and rewards the provers who help secure the chain.

Utility Lens

What Aleo actually does

Lets businesses and people make payments and run apps on a public chain without publishing their balances and counterparties.

Real-world usage
earlyMainnet and private stablecoin payroll are live, but usage is still small and mostly at pilot scale.
Token necessity
essentialALEO pays every transaction fee and rewards the validators and provers that run the network.
Decentralization
moderateAnyone with 10 million ALEO can run a validator, but early backers, the foundation and Provable hold a large share of tokens.
Track record
developingMainnet launched in September 2024 after years of testnets; no major protocol hack appears in our sources.

How we rate

What it’s used for

ALEO is used to pay transaction fees, staked with validators and earned by provers who solve the network's puzzle. The project focuses on private stablecoins: Paxos Labs issues USAD on Aleo, and in January 2026 the payroll firm Toku launched private stablecoin salaries built on it. USDCx, a USDC-backed stablecoin built with Circle's xReserve, debuted on Aleo's testnet in December 2025 and is now live on mainnet, and in October 2026 it became usable in Ledger's wallet app.

Evidence of real use

Privacy: what’s hidden, what isn’t

Privacy model
app-level
What it hides
The contents of private records, including amounts and the owner, and the sender of a private transfer, which is stored in encrypted form for the recipient.
What stays visible
Anything a program stores in public mappings, such as public balances, plus the program and function being called, which can be used to classify activity.
Reality check
Aleo's docs warn that randomizing program names only obscures them, since identifiers can still be discovered. View keys let users disclose records to auditors. ALEO is legal to own in the US and is offered by Coinbase.

Privacy coins, explained

How Aleo works

On most smart contract chains, every node re-runs your transaction in public. Aleo flips this: the program runs on your own computer or phone, which then creates a zero-knowledge proof showing the rules were followed without revealing the inputs. Validators only check that proof. Private data lives in records, encrypted units owned by one address that work a bit like Bitcoin's coins, being used up and replaced when spent.

Developers can also keep data public. Public state sits in mappings, simple key-value tables that anyone can read and that validators update directly. A token can keep each person's balance private in records while showing its total supply publicly. Owners can share a view key, or a key for one single record, so an auditor or counterparty can see specific transactions without seeing everything else.

The network is secured by AleoBFT, a proof-of-stake design drawing on the Narwhal and Bullshark research, with a minimum of 10 million ALEO to run a validator. Alongside them, provers solve a puzzle modeled on generating zero-knowledge proofs and earn part of each block reward. Programs are usually written in Leo, a language designed for this proof-based model.

Key moments

  1. 2022Aleo raises $200 million in a Series B round to build its private-by-default platform.
  2. 2024Mainnet goes live on September 18, and Coinbase provides day-one support for the ALEO token.
  3. 2025USDCx, a USDC-backed private stablecoin using Circle xReserve, launches on Aleo's testnet in December.
  4. 2026Toku launches private stablecoin payroll on Paxos Labs' USAD in January, and in October Ledger's wallet app adds support for USDCx on Aleo.

Supply

Aleo launched with 1.5 billion tokens and has no fixed cap. New ALEO is issued to provers and validators, with the inflation rate starting around 12% in the first year and falling to about 2% by year ten. The project expects about 2.6 billion ALEO to be circulating after ten years, and validators also earn a constant block reward indefinitely.

Risks to understand

  • Privacy depends on how each app is written: data put in public mappings, or revealing program and function names, can be seen or used to classify activity.
  • Supply keeps growing through block rewards, and early backers, employees and the foundation received a large share of the initial tokens.
  • Private stablecoin use is new and depends on a few partners such as Paxos Labs, Circle and Toku.
  • Zero-knowledge systems are complex, and bugs in proof systems or apps could have serious effects.
  • From July 10, 2027 the EU bars regulated crypto providers from handling anonymity-enhancing coins, a rule that could restrict EU access to privacy-focused assets.

Aleo FAQ

Is Aleo a privacy coin?

It is a privacy-focused smart contract chain. Apps can keep data in encrypted records, but they can also use public mappings, so privacy depends on how each app is built.

Can I buy ALEO in the US?

As of October 2026 Coinbase says Aleo is available on its exchange.

What is a view key?

A key that lets someone read your private records without being able to spend them, useful for audits or tax reporting.
