Welcome to Atto Documentation
Atto is live, feeless digital cash built for payments. It confirms quickly, has no protocol transaction fees, and keeps consensus lightweight enough for everyday use.
Quick Start
Create a wallet
Open the web wallet, create an account, and receive your first transactions.

Core Documentation
Whitepaper
The technical overview of Atto's consensus, account-chain model, supply, and security assumptions.
- Open Representative Voting (ORV) consensus
- Account-chain architecture
- Anti-spam mechanism via lightweight PoW
- Fixed supply of 18B coins (no new minting)
- Representative voting rather than competitive proof-of-work mining for consensus
Token Distribution
How Atto enters circulation through the faucet, Folding@Home mining, staking rewards, and contribution rewards. Rates and eligibility follow the current reward policy. The Growth Stability Index (GSI) adjusts configured rates for distribution programmes that use it.
- Faucet for new users
- Folding@Home mining for research contributors
- Staking rewards for eligible accounts delegated to participating voters
- Contribution rewards for useful work
Distribution and Reward Routes
Reward eligibility, rates, and timing depend on the current rules for each route and may change.

Key Features
Instant Transactions
Atto does not wait for a shared block queue. Transactions are processed as they reach the network, and the current median/P50 confirmation time is about 176 ms. A transaction may be treated as confirmed when it satisfies the network's then-current voting rules. Confirmation and recovery still depend on software, voting-weight distribution, connectivity, infrastructure, and operating conditions.
Zero Fees
Atto has no protocol transaction fee. If you send 1 ATTO, the recipient receives 1 ATTO. That makes small payments, tips, faucets, and everyday transfers practical instead of being eaten by fixed network fees.
Lightweight Consensus
Consensus is voting, not mining. Each transaction includes a small proof-of-work to slow spam, but representatives decide confirmation through Open Representative Voting (ORV). The result is a payment network that stays lightweight without turning security into an energy race.
Secure & Decentralized
Each account controls its own chain of transactions, and conflicting updates are resolved by representative votes. Delegation assigns representatives voting weight without transferring custody of the account's funds.
Scalable
Atto uses account chains instead of one shared block queue. Independent accounts can move in parallel, so the network is not forced to serialize every payment through a single global block.
Use Cases
- Micropayments for pay-per-use services, content tips, and in-app purchases
- Retail payments where checkout needs fast confirmation and no network fee
- Remittances where the sender should not lose value to fixed transfer fees
- Machine-to-machine payments for small automated transfers
- Gaming balances, item trades, donations, and tips
How Atto Works
Open Representative Voting (ORV)
Instead of mining blocks, Atto holders delegate voting weight to representatives they trust. Representatives vote on the validity of transactions and confirm the winning state.
Account Chains
Each account has its own chain of transactions. That lets independent accounts move in parallel instead of waiting for a single global block queue.
Anti-Spam Protection
To prevent spam without fees, Atto requires a small proof-of-work for each transaction. The work is lightweight for normal use but makes bulk spam more expensive.
Fixed Supply
The full 18 billion ATTO supply was created at genesis. No new coins can be minted; distribution programs move that existing supply into circulation over time.
