Following last night’s successful update proposal – initiating the Shelley hardfork – we’ve had a very productive and positive day today here at ‘mission control’. Lots of progress optimizing against all areas, including the wallet backend, cardano-graphql, cardano-db-sync, Daedalus and of course, the node.
So Sam has just spun up a new test network (MC4) based on today’s fresh 1.18.0 node release, which hard forked to Shelley at 19:00 UTC.
We have a high level of confidence that this node version will be the final candidate we endorse before the mainnet hard fork. So we’re asking our stake pool operators (SPOs) to now join this new network.
We’re asking our pioneer pools to put it through its paces over the next 24 hours or so. If all goes well, this is the version which will become the new network that we’ll ask EVERY ada holder to join, for a last bit of testing and tasting, just before the hardfork.
Alongside this, we’ll gradually be retiring all our other public mainnet candidates (including MC3, which was based on the 1.17.0 node and the ‘original’ Shelley testnet (shelley_testnet). This has been running on the 1.15 node (Shelley only, no Byron mainnet compatibility) so its time to remodel the experience for everyone!
Assuming all goes well with MC4, this will form the basis of our next ‘mainstream’ release, available to every ada holder who’d like to have a play with it. We’re planning to integrate with Daedalus tomorrow, and release a brand new Daedalus either Sunday evening UTC or Monday morning. We’re very close to mainnet now, but we’d still like every ada holder can experience a (very near-!) ‘Shelley experience’, prior to the hard fork and the real thing after the 29th of July.
Thanks as ever for the support. See you soon!
