What is nano?
Nano is a digital payment protocol designed to be accessible and lightweight, with a focus on removing inefficiencies present in other cryptocurrencies. With ultrafast transactions and zero fees on a secure, green and decentralized network, this makes Nano ideal for everyday transactions.
How do transactions work?¶
Nano utilizes the Block Lattice, a data-structure in which individual accounts control their own blockchain. This allows blocks to be added quickly without conflict and sent to the network for confirmation.
Transactions occur between accounts with two separate actions:
The sender publishes a block debiting their own account for the amount to be sent to the receiving account
The receiver publishes a matching block crediting their own account for the amount sent
Once a block sending funds is confirmed by the network, the transaction goes into a receivable state and cannot be reversed. The receiver can be offline and safely leave the funds in this state until they are ready to publish a matching block receiving the funds to their account.
Lightweight, stateful blocks¶
Nano uses a structure for each block which contains all the information about an account at that point in time: account number, balance, representative.
Every block must also contain a small, user-generated Proof-of-Work value which is a Quality-of-Service prioritization mechanism allowing occasional, average user transactions to process quickly and consistently. The PoW computation for a transaction typically takes a few seconds on a modern desktop CPU.
For more details, see the Blocks and Proof-of-Work specifications in our Integration Guides.
Representatives and Voting¶
Nano has a unique consensus mechanism called Open Representative Voting (ORV). Every account can freely choose a Representative at any time to vote on their behalf, even when the delegating account itself is offline. These Representative accounts are configured on nodes that remain online and vote on the validity of transactions they see on the network. Their voting weight is the sum of balances for accounts delegating to them, and if they have enough voting weight they become a Principal Representative. The votes these Principal Representatives send out will subsequently be rebroadcasted by other nodes.
As these votes are shared and rebroadcasted between nodes, they are tallied up and compared against the online voting weight available. Once a node sees a block get enough votes to reach quorum, that block is confirmed. Due to the lightweight nature of blocks and votes, the network is able to reach confirmation for transaction ultrafast, often in under a couple seconds. Also note that delegation of voting weight does not mean staking of any funds - the account delegating can still spend all their available funds at any time without restrictions.
Because Nano accounts can freely delegate their voting weight to representatives at any time, the users have more control over who has power with consensus and how decentralized the network is. This is a key advantage to the design of Open Representative Voting (ORV). With no direct monetary incentive for nodes, this removes emergent centralization forces for longer-term trending toward decentralization of the network.1
Design Advantages¶
Nano was designed with new data structures, consensus mechanisms and other features to gain some key advantages over competing digital currencies:
Minimal block size allows for lightweight communication resulting in ultrafast transaction confirmation times
Without traditional Proof-of-Work and mining, nodes use significantly less energy per transaction than other popular networks
Emergent centralization forces for node operators are reduced due to the near zero marginal cost of producing consensus in Nano 1

Comment:
Anyone who has studied wave theory understands the analysis is not time/space dependent. Still valid despite one kid who is shilling his favorite coin and trolling my post. Im an analyst not a fanboy and I have no bias on Nano. Im not affiliated with that $&!%coin.
