The BNB Beacon Chain testnet is expected to have a scheduled hard fork upgrade at block height 23,551,600. Based on the current block generation speed, the hard fork is forecasted to occur on March 15, 2022, at 06:00 AM (UTC). The full node runners on testnet must switch their software version to v0.9.0 by March 15, 2022.
This upgrade is named after René Descartes in honor of his key contributions to philosophy and mathematics. He was a French philosopher widely regarded as one of the founders of modern philosophy and algebraic geometry.
A Hardfork is an upgrade that is not compatible with the previous release because some breaking changes are introduced in the latest release. A hardfork in BNB Beacon Chain requires more than ⅔ 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 23,551,600. 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.
There are no changes to the BNB Beacon Chain DEX matching engine logic. No action is required on your end.
This is a hardfork release, and you need to switch to v0.9.0. Upgrade instructions are as below (you should do all the below before the hardfork block height):
3. Stop the bnbchaind process and restart it with v0.9.0.
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 23,551,600, you can run the following command to recover the state to just one block before the upgrade, which is 23,551,599:
./state_recover 23551599 <your_home_path>
3. Restart with the version v0.9.0 of bnbchaind
bnbchaind start --home <home-path>
