monolithic blockchain

Ethereum before sharding was a monolithic blockchain where every node handled all tasks simultaneously.分片之前的以太坊是一个单体区块链，其中每个节点同时处理所有任务。

Monolithic blockchains face inherent scalability limits since adding throughput requires every node to do more work.单体区块链面临着固有的可扩展性限制，因为增加吞吐量需要每个节点做更多的工作。
