1/ The official Columbus-5 execution plan and set of available resources 👇

At the block height #4,724,000, the Columbus-4 chain will halt and the Columbus-5 mainnet migration will commence.

2/ This roughly translates to the following times:

Wed Sep 29 2021 23:00:00 GMT-0800 (PDT)
Thu Sep 30 2021 07:00:00 GMT+0000 (UTC)
Thu Sep 30 2021 16:00:00 GMT+0900 (KST)

3/ The migration is expected to take roughly 2 hours pending no extenuating circumstances.

The initiation of the migration will be relayed publicly both 1 hour before its execution and also at the precise time that the Col-4 chain halts.

4/ Once the migration is initiated, please DO NOT interact with the Terra blockchain.

This means do not attempt to send transactions, access wallets, or interact with dApps on the Terra network during this time.

5/ Once the mainnet migration is complete, an announcement will be released officially confirming that Columbus-5 is live, stable, and ready to use.

At that point, users and developers will be able to interact with Columbus-5 as the new Terra mainnet.

6/ Individual applications, specifically @mirror_protocol and @anchor_protocol, will initiate a 3-hour window for users with open debt positions to deposit collateral and safely ensure liquidation risk is mitigated for those users AFTER the completion of the mainnet migration.

7/ You can find the individual rundowns of how the execution of the price feed freeze will occur for both Mirror and Anchor in the respective Tweet threads below:

Almost time to fly 🌕
