Love it! My favorites are dark and zebra modes

For the production version of red·bridge, we will be using Zebra. In preparation and for testing purposes, over the past week we have upgraded two out of the three nodes running ZavaX Oracle, our proof-of-concept blockchain for red·bridge. ZavaX Oracle is a small permissioned Avalanche subnet running on Avalanche’s Fuji testnet.
The upgrades went smoothly (well, pretty smoothly!), and we learned a few things along the way. Now we are ready to upgrade the third node, and that will require some downtime because of limited disk space on that server. ZavaX Oracle will be in maintenance mode until this upgrade is complete. We estimate 1-5 days depending on the amount of time it takes to completely sync Zebra. I’ll post again when it’s up and running again, this time with new Zebra installations on all nodes!

Great news, the upgrade of the third node went smoothly and was completed over the weekend, and now ZavaX Oracle is using ZEBRA!
Next up, we will be upgrading the ZavaX Oracle Subnet from an Avalanche Subnet to an Avalanche L1.

Ten days ago, I was on a panel at the Avalanche Summit in London, and I got a chance to talk about red·bridge. Here’s a sneak peak. The subject of the panel is about how to get funding, but I did get a chance to introduce red·bridge to about a hundred people in the Avalanche community. Afterwards, I was talking with a VC, and he said, “Oh! So you’re building something real!” I think we’re a bit of a breath of fresh air among all the meme coin pump-and-dumps!
Project update coming soon!

Today we are submitting milestone ACP-77 Architecture Revisions to the Avalanche Foundation. This might sound a bit dry 
, but it’s actually very very cool 
, and let me explain why.
The friendlier name for ACP-77 is Avalanche9000, and it is a huge upgrade for Avalanche that dramatically lowers the cost of anyone running a red·bridge guardian. Before Avalanche9000, you would have had to stake at least 2000 AVAX (about $44,000 today) to even run a validator. That’s because you used to have to validate the primary Avalanche network in order to validate another one like red·bridge. No more! To run a red·bridge node with Avalanche9000, it costs about 1 AVAX ($22 today) per month, plus you will need to obtain and stake RBR tokens. (And fear not, for anyone reading this post, we will have opportunities ahead for the Zcash community to obtain some RBR.) This puts bridge guardianship within the reach of a far wider group than would have been possible prior to Avalanche9000.
We have also wrapped into this milestone a solidification of our strategy using ZF’s FROST implementation. Huge thanks to @conradoplg for help as we made sure we understood everything just right. The bridge wallet will be a FROST wallet, and each Guardian will have a signing share, giving distributed control.
If you’re interested in digging into the UML documents and seeing the changes we’ve made, check out our repo. We have made changes throughout, but the bulk of the changes were made to the Maintain Guardians use case.
Thanks also to @ZCG and Avalanche Foundation for your ongoing support or the red·bridge project, to @pacu for your support, and to the entire red·dev team for your support with this milestone! So interesting and exciting for us to combine Avalanche and Zcash technologies together! Next up: establishing a good threat model for ZavaX Oracle, our early proof-of-concept, and building the bridge itself. Onward!
