@MeherRoy "Checkpointing" undersells it a bit imo. It's a fair description for validiums and sidechains, but for rollups they're paying for data space, and so outsourcing their own internal need to worry about decentralization.
@MeherRoy“Checkpointing”在我看来有点低估了它。这是对Validium和侧链的公平描述，但对于汇总，他们为数据空间付费，因此外包他们自己的内部需要担心分散化。
