This article formally announces the Andromeda Hard Fork with upgrade details.

Hard fork block

Andromeda is the next hard fork for Ubiq and is planned to activate at block 1,075,090 alongside the next scheduled reward stepdown, currently estimated for 14th of January, 2020.

Changes

The Andromeda hark fork has been in development and testing for the past few months by the Ubiq core development team.

This update consolidates and will activate Byzantium, Constantinople & St. Petersburg EIP’s from upstream Ethereum and includes a fix for uncle reward calculations. There has also been some much needed clean up and refactoring of our consensus code.

The next major development will implement the Ethereum Istanbul EIP’s and is anticipated to be completed mid-2020.

Gubiq 3.0.1

Gubiq 3.0.1 full node is now available:

https://github.com/ubiq/go-ubiq/releases/tag/v3.0.1

All services which run Ubiq nodes must upgrade ASAP. Fusion wallet will be updated to point to the latest version and you will automatically be prompted to upgrade.

Open Ethereum Pool

We have added additional tests to the Modified Open Ethereum Pool and it looks like the Uncle reward calculations were always correct there. They were only incorrect in the Gubiq code (to be fixed in the hard fork).

Outreach

This is a call to the community to please actively inform others about the Ubiq hard fork upgrade and to contact services and software providers that you currently use.

FAQ

Here are some further questions not covered in the above:

What do I have to do with my coins?

Nothing. Ubiq holders can simply keep their coins on a private wallet, hardware wallet or on exchange.

Will I have to update Fusion?

Fusion will prompt you to update your version of Gubiq. The Fusion front end can remain unchanged.

Does this mean we will have two Ubiq chains like ETH and ETC?

This hard fork is part of our roadmap announced in April 2019. This hard-fork upgrade is not contentious and therefore the likelihood of a chain split is low.

Are the exchanges supporting the upgrade?

Exchange partners have been notified of the update and we do not anticipate any issues.

Are hardware wallets supporting the upgrade?

Your hardware wallet requires no changes to use the upgraded chain. Wallet software like Pyrus will be updated with no effect on your Ledger or Trezor.
