Originally developed under the name RaiBlocks beginning in 2014, the project delivered a public faucet distribution in 2015 and rebranded to Nano in January 2018. The protocol's core mission is to enable fast, energy-efficient payments with a minimal friction user experience: accounts maintain individual chains (account-chains) and transactions update only the balances of the two accounts involved, allowing for asynchronous, near-instant settlement without per-transaction fees. The Nano Foundation and community contributors have stewarded the protocol through several engineering cycles and community-driven initiatives, and the project emphasizes an open, permissionless design aimed at merchant and micropayment adoption. Technically, Nano departs from traditional single-chain block models by adopting the block-lattice (DAG-like) structure and securing transactions via Open Representative Voting (ORV). Rather than proof-of-work mining or proof-of-stake validation, account holders select representatives who vote on the validity of transactions, with voting weight proportional to account balance. This design eliminates transaction fees and enables very low-latency confirmations. The reference node implementation (Nano Node) is implemented in C++, and recent engineering efforts culminating in the v28 release series focused on bootstrap, RocksDB-backed storage optimizations, networking resilience (bounded block backlog, traffic shaping), and other improvements targeted at production-grade performance for exchanges, merchants, and infrastructure providers. Nano's primary use cases are frictionless value transfer, micropayments, and merchant payments where fee-less instant settlement is important. The network's feeless transactions and quick confirmations make it well-suited for small-value transfers, tipping, and micropayments tied to content and microservices (for example community examples such as NanoGPT integrations). The ecosystem includes hardware and desktop wallet support (notably Ledger and Electrum-style clients), several major centralized exchanges for liquidity, and explorers/analytics providers that index the ledger for transparency. Adoption milestones include the community-driven faucet distribution, the 2018 rebrand to Nano, and ongoing node/software upgrades; merchant-focused initiatives and hub listings have aimed to improve real-world acceptance. Tokenomics and governance for Nano are atypical compared with many token projects: there is a fixed, hard-capped supply and no block rewards or inflationary issuance. Early distribution was accomplished via a public faucet and a small developer holdback reported in extracted sources (around 5% cited as a developer fund). There is no ongoing staking reward stream; consequently monetary policy is essentially fixed supply with distribution managed historically through the faucet and community/foundation activities. Governance is primarily off-chain via the Nano Foundation and community coordination, while transaction validation relies on ORV; the ecosystem moved toward a more volunteer-led operating model in 2023. Recent development activity (2024–2025) with the v28 node series indicates renewed engineering focus on performance, stability, and operational readiness for merchant and exchange workloads, while the project's governance and funding remain centered on the foundation and community stewardship rather than typical VC-driven token economics.
