Individual blocks: One of the main improvements that we can find in the Nano Blockchain is the fact that here each block is an individual transaction. This is a great advantage, since each block can be processed independently and not in a set as happens in Bitcoin. Processing speed: By being able to process the blocks individually and not having to wait for a block to be formed, the time or speed of transaction processing becomes greater. This increases efficiency and reduces waiting time. Automatically validated transactions: Traditional Blockchains require a user, or group of users, behind to validate transactions. On the other hand, in Nano the validation is done automatically when the PoW is pre-loaded in the form of a pre-cache, which is arranged both in the receiver and in the sender. Voting mechanism: In order to avoid the centralization of powers as happens with the PoW algorithm, Nano has incorporated the Delegated Proof of Stake algorithm. This allows users to vote in case of detecting fraudulent movements or unreliable information. Low energy consumption: By lacking mining, as well as transactions being approved automatically and by using individual blocks and not a set, the energy efficiency of this currency is greater than that of other virtual currencies. This means that the economic and environmental costs of operation are lower. Ledger: One of the bases of cryptocurrencies like Bitcoin is the creation of a generalized virtual ledger which is the livelihood of the Blockchain. In the case of Nano, this is not necessary, since each Wallet is a book in itself which maintains its own balance and count. Number of coins: Another considerable difference is found in the number of coins available for each virtual currency. Litecoin, for example, owns 84 million while Bitcoin barely exceeds 21 million. Instead, Nano already operates with about 133 million tokens, which makes it one of the largest coins in coins. Mined: Finally, you should know that Nano cannot be mined, since its automatic validation mechanism, as well as their Blockchain prevent it. This means that we cannot obtain coins through rewards for validating blocks of the chain.
