((("simple-payment-verification (SPV)")))Some nodes maintain only a subset of the blockchain and verify transactions using a method called _simplified payment verification_, or SPV. ((("lightweight clients")))These nodes are known as SPV or lightweight nodes. In the full-node example in the figure, the full-node blockchain database function is indicated by a blue circle named "Full Blockchain" or the letter "B". In <>, SPV nodes are drawn without the blue circle, showing that they do not have a full copy of the blockchain. -((("bitcoin nodes", "mining nodes")))((("mining and consensus", "mining nodes")))((("Proof-of-Work algorithm")))((("consensus", "Proof-of-Work algorithm")))Mining nodes compete to create new blocks by running specialized hardware to solve the Proof-of-Work algorithm.

The mining function is shown in the full node as a black circle named "Miner" or the letter "M". User wallets might be part of a full node, as is usually the case with desktop bitcoin clients. Increasingly, many user wallets, especially those running on resource-constrained devices such as smartphones, are SPV nodes. The wallet function is shown in <> as a green circle named "Wallet" or the letter "W".
