For example, the data volume of public test networks (such as Ethereum's Ropsten test network) is  relatively small, about 10GB depending on different networks. In contrast, public nodes need to synchronize and store a large amount of data, such as the entire history of the blockchain."}]}],"pr":"e9cee3c1bad56abd92191fcab32948e14c9d44ef3114398ec4df7474f20cc99b"}
