Polkadot Hub Migration Live Ticker
Good morning to Hub migration day. This thread will provide live coverage.
IMPORTANT: DOT transfers will be blocked during the migration! Please don’t try to transfer DOT between chains today.
Live Coverage 👇🧵
Live Dashboard here:
In the first hour, the system is in warmup. Then the actual migration will start. Keep this thread as separate tab, since this will take a few hours
If you are asking: “how TF is it possible to trustlessly migrate DOTs and users from one chain to another?”
Here is the code for you:
In short: it’s a loooot of messages from the relay to AH containing data that are then all confirmed by messages from AH to the relay
Why is this migration even happening?
3 reasons: Cheaper, Faster, better UX
Faster: Polkadot is the fastest decentralised blockchain network on the planet. For the next growth step, most basic functionality needs to move into system chains, so that the base chain can max out on more critical performance items on the base chain and scale to 1m tps. System chains can have faster block times, e.g 500ms and have more DA and compute
Cheaper: system chain transactions cost a fraction (1/100th) of relay chain transactions
Better UX: moving everything to a system chain will allow smart contracts, more secure assets, governance and staking all live on the same chain while the system can scale to 1m tps
Here Jan Jan from Parity on the complexity of the migration:
This Tuesday marks one of the most complex live upgrades ever attempted on a blockchain.
@Polkadot's Asset Hub migration isn’t just complex; it’s industry-defying.
As Jan Jan, Technical Program Manager at Parity, put it:
“This project is incredibly hard, and the margin for error is zero. It’s only possible thanks to a world-class team of engineers and partners standing by across the globe."
Last phase of the migration! Staking
Looks like we might be done soon
And we are done!
Now cool-off phase to give devs time for post-flight checks. After about an hour the migration should be considered complete.
Your favorite apps and CEXes should also be updated, but don't panic if something doesn't look right. It might just be that your app shows it wrong if it didn't yet update.
Next step will be to see if all parachains handled the migration gracefully
