These days, I've been discussing concurrency and sharding again, and the group chat is filled with an atmosphere of "performance taking off"... I’d rather first pull out the risk control table to review. To put it simply, no matter how fast it gets, it must be able to exit safely: what are the collateral assets, how does the oracle feed prices, how long is the liquidation delay, and if cross-chain or cross-shard messages get stuck, will it cause the collateralization ratio to instantly distort? The kind of inflation + studio + coin price spiral in blockchain games is actually a common pattern: when liquidity thins out, the selling path immediately narrows. Anyway, I’m now looking at new narratives, setting a bottom line for myself: can I close the position with the fewest jumps under pressure, rather than ending up with only "the technology looks beautiful."
