What Is Nano?

Nano (XNO, formerly RaiBlocks/XRB) is a cryptocurrency designed to be a fast, feeless, and energy-efficient digital currency. Created by Colin LeMahieu and first published as RaiBlocks in December 2014, the project launched its beta network in 2015 with the goal of solving the scalability and fee problems that plagued Bitcoin and other first-generation cryptocurrencies. Nano uses a unique block-lattice data structure where each account has its own blockchain, enabling asynchronous transaction processing. Transactions settle in under one second with zero fees.

Nano's block-lattice architecture fundamentally differs from traditional blockchains. Instead of all transactions competing for space in shared blocks, each Nano account maintains its own chain of blocks. A transaction consists of two blocks: a send block on the sender's chain and a receive block on the recipient's chain. This design eliminates competition for block space, removes the need for mining or staking fees, and allows transactions to be processed independently and in parallel. Because each account-chain can be updated asynchronously, the network avoids the bottleneck of a single global ledger.

Consensus on the Nano network is achieved through Open Representative Voting (ORV), a form of delegated proof of stake where account holders delegate their voting weight to representative nodes. When a conflicting transaction is detected, representatives vote on which transaction is valid, weighted by the balances of the accounts that delegated to them. Representatives do not earn any rewards — they operate voluntarily, motivated by their interest in the network's health, keeping the system feeless. Any wallet address can serve as a representative, though good representatives maintain high uptime to participate in voting reliably.

The entire Nano supply (133,248,297 XNO) was distributed through a CAPTCHA-based faucet system that ran from 2015 until October 2017, when the remaining undistributed supply was burned. This distribution method was intended to be fairer than an ICO or mining launch, allowing anyone with internet access to earn Nano by completing CAPTCHAs. There is no inflation, no mining, and no staking rewards. The fixed supply and zero-fee model mean Nano's value proposition is purely as a medium of exchange.

In January 2018, the project rebranded from RaiBlocks to Nano to better reflect the simplicity and speed the protocol offers. Shortly after the rebrand, the BitGrail exchange — which had been one of the primary trading venues for XRB — collapsed in February 2018, with approximately $170 million in Nano lost. The incident was attributed to the exchange's mismanagement rather than any flaw in the Nano protocol, but it significantly impacted the project's early community.

Nano is one of the most energy-efficient cryptocurrencies in operation. Because it relies on lightweight ORV consensus rather than Proof of Work mining, the entire network consumes a negligible amount of electricity. A full Nano node can run on low-power hardware, and the protocol fits a single transaction within a single UDP packet. This green cryptocurrency positioning distinguishes Nano from proof-of-work chains like Bitcoin, which consume terawatts of energy annually.

The Nano Foundation, a non-profit organization, oversees protocol development and ecosystem growth. Development has focused on improving node performance, spam mitigation through prioritized transaction confirmation, and tooling for developers. Nano's primary use cases include micropayments, point-of-sale transactions, and remittances — any scenario where instant settlement and zero fees provide a clear advantage over traditional payment rails or fee-bearing cryptocurrencies.

Getting Started With Nano

Getting started with Nano is simple:

  1. Step 1: Download a Nano wallet. Natrium (mobile) or Nault (web/desktop) are popular choices.
  2. Step 2: Purchase XNO from a cryptocurrency exchange.
  3. Step 3: Transfer XNO to your wallet — the transaction will arrive in under a second with no fee.
  4. Step 4: Send Nano to anyone instantly and for free. Optionally, choose a representative to delegate your voting weight to.

Latest Nano News

Nano continues to focus on its core value proposition as feeless, instant digital money. Protocol upgrades (V25 and beyond) have introduced improved spam mitigation through prioritized confirmation, where transactions backed by accounts with higher balances or longer-held funds receive priority during periods of high network activity. The Nano Foundation maintains active development with improvements to node performance, bandwidth efficiency, and developer tooling. Compared to DAG-based peers like IOTA, Nano remains singularly focused on peer-to-peer payments rather than IoT or smart contract functionality, and its lightweight consensus model continues to attract users seeking a green alternative to proof-of-work currencies.
