Cosmos Hub 每次进行破坏性升级时，网络都会在高度 0 重新启动。在此过程中，会导出前一个网络的最终状态，用于生成新网络的创世状态。 因此，旧网络的区块不会被新客户端下载（因为它们会从新的创世状态开始同步），并且现有全节点也可能会删除这些区块。

With each breaking upgrade of the Cosmos Hub, the network is restarted at height 0. During this process, an export of the last state of the previous network is made to produce the genesis state of the new one. As a result, the blocks of the previous networks are not downloaded by new clients (as they sync from the new genesis state), and may be deleted by existing full-nodes.

Archive Snapshots

Legacy chain snapshots and binaries (linux-amd64) are provided by CCValidators. Always do your own research before trusting a third-party snapshot provider.
