The BSC mainnet is about to initiate the Fermi hard fork upgrade, which is an important network optimization.

Upgrade details are as follows:
⏰ Activation time: January 14, 2026, 02:30 AM (UTC)
✅ Compatible versions: v1.6.4, v1.6.5

All validators and block producers must complete client updates before the hard fork trigger, otherwise they may experience validation or block production issues. This is crucial for maintaining network stability. If you are running a BSC node, it is recommended to complete the upgrade preparations a few days in advance to avoid disconnection risks during the hard fork. Detailed upgrade steps and technical instructions have been published; please refer to the official documentation to complete the process.

It's another hard fork and upgrade; validators will have to go through the hassle again. --- Everyone, please update your clients before January 14th, or you might really get disconnected. --- v1.6.4 should be enough, why insist on upgrading to a new version? --- Upgrade early for a better experience; delaying might really cause issues. --- Every hard fork is a gamble, hoping no bugs appear. --- With BSC's frequency, it feels like it will never end.

Another hard fork, node operators need to act quickly Speaking of which, the Fermi upgrade really can't be delayed. It must be completed before January 14th, or don't blame me if you go offline BSC keeps upgrading so frequently, it feels like there's no peace for a year Remember v1.6.4 and v1.6.5, only these two versions are usable It's never too early to get started, don't wait until 2:30 AM that day and suddenly find yourself falling behind the network haha

Another hard fork is coming. This time, it really won't go offline, right? --- Brothers, hurry up and update, or you won't be able to mine blocks later. --- Why is it always so rushed? Can't the advance notice be a month earlier? --- Problems for v1.6.5 users are not significant; it mainly depends on how quickly validators respond. --- Another hassle, so annoying. --- A week before the hard fork should be enough to prepare; no need to be too nervous. --- What can Fermi optimize this time? Is it just another gimmick? --- Node enthusiasts are trembling; it's time for duty again. --- Upgrading at 2 a.m. UTC, the time zone folks are suffering. --- The risk of disconnection is real; I’ve been burned before.

Another hard fork, can we avoid surprises this time Upgrade early or just wait to get disconnected, everyone Fermi upgrade, it feels like the same routine every time Which is more stable, v1.6.4 or v1.6.5? Has anyone tried? Operations and maintenance are really exhausting, need to prepare in advance Mid-January at this point is quite awkward BSC's infrastructure awareness is still there, but proper execution is the key Validators are going to be busy again The most annoying thing about node upgrades is the strict timing Can we fix all the issues at once, instead of constant small tweaks

Another hard fork and urgent update. What is BSC up to this time? Quickly check the node version to avoid going offline later. Mid-January 2026, note it down. Early preparation is never wrong; this is basic validator operation. Fermi optimization... Sounds like a performance adjustment. Looking forward to subsequent feedback.

January 14th 02:30... It's that time of night again for operations, node maintenance folks have to stay up late. v1.6.4 and v1.6.5 compatibility is fine, but you must ensure all validators have truly updated; otherwise, a fork could cause blocks to drop immediately, which is a serious flaw. --- Nodes that are unprepared before a hard fork, get ready to be kicked out of consensus. I’ve already scheduled this on my end; efficiency is the key to competitiveness. --- By the way, what exactly will this optimization change? Saying "network optimization" is too vague; we need to see whether it’s about consensus or gas calculation to assess the risks. --- Can staking yields still be guaranteed? Will there be any interruption during the upgrade... That’s what operators care about most. --- A few days in advance? I suggest preparing the test environment a week ahead, don’t leave it until the last minute. --- It’s always UTC time, I have to convert every time, so annoying. But this time, the compatible version range isn’t too broad, which is actually a good thing—limiting the version range reduces variables. --- Can I just look at the official documentation? Well, it depends on how well the documentation is written... Some official manuals are truly disastrous.
