Next stage in #DeFiKernel evolution: the amazing premise that loans under high-volatility conditions we all share in the crypto world can be the *solution* to that volatility ⭐ since this tech allows loans to be extended without margin 🤠 @__fallen_icarus iog.io/news/non-margin-defi-…

Only rarely can we see the next stage of the future when it's mostly unknown but practically proven. 🚀 No developer hurdle or organisational prejudice is too great to make the #DeFiKernel a reality; thanks again to @__fallen_icarus for never giving up 🏆 iog.io/news/the-account-mode…

Cardano has a lot of visible work: launches, announcements, debates, big ideas. But a healthy ecosystem also depends on the unglamorous work that almost nobody sees, the editing, review cycles, cleanup, coordination, and relentless attention to detail that turns rough drafts into something the community can actually build on. This year, a huge amount of that load has been carried by Robert Phair (@rphair). He’s spent countless hours moving the CIP process forward: editing, reviewing, nudging, fixing typos, making commits, and doing whatever was needed to keep proposals progressing. It’s thankless work, and most people won’t even know his name; yet it is the foundation of the entire ecosystem. If you care about Cardano maturing, you should care about the people doing this kind of stewardship. Robert is one of those rare contributors who shows up consistently, does the hard parts, and rarely asks for anything. He deserves real recognition for the impact he’s had.

Thanks @__fallen_icarus to your trust and cooperation I've known long in advance that this would happen someday 😇 ... but still the confirmation is exhilarating & empowering: a long awaited market that can't really be duplicated outside #cardano 😍
The @IOGroup BitcoinDeFi project will be utilizing the DeFi Kernel's credit market! 🎉🎉 $BTC and $ADA HODLers maintain full self-custody while assets are locked as collateral—with zero margin call risk. Hopefully, this is the start of a new era for #Cardano's #DeFi🤞 #Bitcoin

Meet Robert Phair (@COSDpool), one of the newest Ambassadors to join the Cardano Ambassador Program. Robert brings decades of experience and a strong belief in open-source, and this comes through clearly in his long-standing work on Cardano’s CIPs and documentation. Few people have contributed as much to shaping the ecosystem’s written standards and helping preserve its long-term memory. He’s committed to helping Cardano grow through clarity, good documentation, and accessible standards that everyone can build on. His message to the community: “Stay generous with your ideas. What you give, you get back many-fold.”

This is more than just a good P.R. campaign... 😍
Location: North Carolina 🇺🇸 Status: AirNodes Installed ✅️ In a world where connectivity is everything, we simply had to do something for people who've been left with nothing. Read on to learn about the #WorldMobile disaster relief efforts in the wake of #HurricaneHelene.

Wow 🤓⭐
It’s also very interesting to think about what would a UPLC-Midnight version could look like. Can ADA act as NIGHT? Generating an equivalent for DUST on the UPLC-Midnight partnerchain, which becomes the fuel to use that chain, and assuming most users, liquidity, and activity will go there. E would also gain a lot in terms of privacy... And does this mean you can use the chain by just holding ADA, rather than having to spend it... You still need to pay ADA fees on the L1, but not on UPLC-Midnight, you can just spend the DUST equivalent generated by your ADA. In this sense it sounds even more sustainable than regular Midnight, because how will Midnight producers make money after inflation of the supply of NIGHT is over, if there are no such thing as NIGHT fees or NIGHT inflation? This makes me want our own UPLC-Midnight partnerchain even more now. 🤤

When #Cardano' progressing URI framework matures, it's going to eat this #Solana framework alive. 🦈 Note the centralisation and whitelisting (i.e. censorship) advertised as long-awaited features: 🧐 @adamKDean @Ryun1_ @_KtorZ_ @adatainment @NicolasC3rny cointelegraph.com/news/new-s…

... compared to #Cardano's framework for *any* provider to publish web links for payments, stake delegation, blockchain query, airdrops & metadata... with any dApp, no matter how small, choosing which of these to support: without permission from anyone 🤠 github.com/cardano-foundatio…

This is exactly the kind of thing we were thinking of when initially developing, and committing our own pool operations to, the Frankenwallet... and thanks again to #Cardano #ProjectCatalyst for selecting our project in Fund 11 😍 @NicolasC3rny @Ryun1_  projectcatalyst.io/funds/11/…

Attention all Cardano Stake Pool Operators, Please pay close attention to this critical announcement if you currently manage your pool keys using a Ledger Nano S hardware wallet. We are eagerly anticipating the release of two significant updates for the Cardano Ledger app: versions 6.1.2 (with extended Catalyst support that has been added in 6.0.0) and 7.0.0 (Voltaire/Conway support), with version 7.1.0 (off-chain message signing) nearing completion. However, of even greater importance, Version 7.0.0 will mark the beginning of a Cardano Ledger application split. Starting from this version, there will be distinct feature sets between the Nano S Cardano Ledger app and the Cardano app for other Ledger devices. This divergence is driven by memory constraints inherent in the Ledger Nano S. After careful consideration, it has been determined that the most effective approach is to maintain primary end-user functionalities on the Nano S. Therefore, as of version 7.0.0, stake pool operations will no longer be supported on the Nano S. This requires stake pool operators to transition to a Nano S or Nano X device to continue managing their pool keys using a Ledger device. Consequently, signing pool registration certificates, pool retirement certificates, and pool operational certificates will no longer be possible on the Nano S starting from Cardano app version 7.0.0. Furthermore, the derivation of native script hashes will be removed from the Nano S app, as this functionality is not utilized in any major use case known to us. Also, this derivation can still be performed off-device, given the available use cases. The expected release date for Cardano app version 7.0.0 is the first half of March.
