Solução de Nodos de Baixo Armazenamento para o Futuro da Internet
In blockchain, full nodes (FNs) store all existing transactions and are responsible for validating new blocks. The amount of data stored by FNs has been increasing significantly in popular blockchains, such as that of Bitcoin. The excessive amount of data from blockchains increases the storage and processing overhead in FNs, which may cause a reduction in the number of devices that validate and store blockchain data. Also, it may put the decentralization principle of blockchain in risk. This paper proposes a less expensive data storage mechanism for blockchain FNs. The proposed mechanism aims to reduce the storage and processing overhead in FNs, and to guarantee the decentralization characteristic of the network.
