The BNB Beacon Chain mainnet is expected to have a scheduled hard fork upgrade at block height 328,088,888. Based on the current block generation speed, the hard fork is forecasted to occur on 19th July 2023. at 6:00 (UTC). The full node runners on mainnet must switch their software version to v0.10.16 by 19th July.
Zhang Heng (AD 78–139), was a Chinese polymathic scientist and statesman who lived during the Han dynasty. He achieved success as an astronomer, mathematician, seismologist, hydraulic engineer, inventor, geographer, cartographer, ethnographer, artist, poet, philosopher, politician, and literary scholar.
A Hardfork is an upgrade that is incompatible with the previous release because some breaking changes are introduced in the latest release. A hardfork in BNB Beacon Chain requires 2⁄3 of validators to upgrade to make blocks successfully. If the existing full nodes in the network do not upgrade, they will not receive and execute further blocks after the hardfork block height.
New rules and logic changes will occur for this upgrade at block height of 328,088,888. After the upgrade kicks in, the blockchain can handle a series of new business rules and logic.
If you are using any exchanges which support BNB (such as Binance.com, BitMax, or Gate.io), one of the wallets, or a hardware wallet (such as Ledger, Cool Wallet), there’s no action required on your side unless your exchange or wallet service notifies you.
This is a hardfork release, and you need to switch to v0.10.16. Upgrade instructions are as below (you should do all the below before the hardfork block height):
ulimit -n 65535
bnbchaind start --home <home-path>
If you fail to upgrade your software on time, your node will not sync with the upgraded BNB Beacon Chain peer/validator nodes. You will not be able to connect or send transactions.
How to recover?
You can find detailed info at doc-site.
Since the height of the upgrade is set to be 328,088,888, you can run the following command to recover the state to just one block before the upgrade, which is 328,088,887:
3. Restart with the version v0.10.16 of bnbchaind
There will be no difference for users of BC.
Thanks for your cooperation, and let’s make BNB Beacon Chain a modern and secure infrastructure for the BNB ecosystem.
