I've been diving for a long time, and seeing someone ask again "Why does on-chain data suddenly freeze/not update," I can't help but say a few words... Many times, it's not that the chain has stopped, but that the data service layer you're viewing is struggling. For example, Subgraph/indexers need to scan the on-chain events first and then organize them into queryable results; reorganization, rollbacks, and data supplementation can all cause delays. Plus, with RPC rate limiting, when public nodes are busy, they give you 429 errors or queue you, which makes the front end appear "frozen." To put it simply, you're querying the "processed chain," not directly reading blocks. Recently, the staking and shared security setups have been criticized as being overly complex, which is similar: the more layers stacked above, the more sensitive each link is—if one part falters, everyone below feels it’s all broken. Personally, I still stick to my usual approach: dollar-cost averaging + minimal tinkering. When encountering lag, just switch nodes or wait a bit—don't panic and make reckless moves.
