This morning, watching the sea, wave after wave crashed in parallel, lively and bustling, but when it comes down to it, it's still about whether the rocks are stable or not. The same goes for the blockchain; recently, that mainstream public chain is upgrading/maintaining, and everyone in the group is guessing whether the ecosystem will move away. I'm actually more concerned about: where my assets are placed, whether I can get them out or not. Sharding or parallel processing, the narrative sounds exciting, but when the chain stalls, bridges get clogged, or withdrawals are half a beat slow, you realize how real the words "exit route" are. Conclusion: chasing new things is fine, but first think through permissions, backups, cross-chain, and escape routes—don't wait until the waves are high to look for a life buoy.
