Grin, as the first implementation of MimbleWimble, argues that MimbleWimble The data size of a node is significantly reduced compared to Bitcoin, "compared to a gigabyte-sized Bitcoin blockchain node. Grin node sizes can be optimized by orders of magnitude, even down to a few hundred M bytes" according to Grin's Description, assuming 10 million transactions accompanied by 1 million UTXOs and no transaction write-offs for the blockchain The total size is approximately 130GB, with 128GB of transaction data, 1GB of proof of transaction data, and block headers of 250MB. with write-offs, the total size of the block can be reduced to 1.8GB, including 1GB of output data. 520MB of UTXO (should be transaction kernel or proof of trade data) and 250MB of blockchain.
