Last night, I was monitoring the blockchain, clearly seeing a large transfer "just happened," but when I switched to a different RPC, the timestamps didn't match... Basically, you think you're seeing real-time data, but in reality, there's node synchronization, RPC caching, indexer batch processing in between, and if one is a beat slow, you're always a beat late. Especially when a block just came out and the mempool is crowded, it looks like "on-chain anomalies," but maybe it's just your data feed being a bit delayed. Recently, that mainstream chain is about to upgrade, and everyone in the group is guessing whether the project will migrate. I'm actually more worried about various services experiencing a hiccup before and after the upgrade, causing the on-chain dashboard to get messy for a while. By the way, my colleague even showed me a screenshot from a certain browser arguing that "the transaction has already been completed," but I couldn't be bothered to argue... better to watch a couple of sources first, for stability.
