I'm giving a quick example for signing with #Kadena Spirekey. First, you create a Transaction; then it sends you off to sign; then, upon return, our site has to handle sending the transaction and the status of success/failure. Sends and spends your $KDA all the same. Next up I... show more

Dealing with popups and signing for every transaction is one of the worst parts of crypto UX. So we fixed that. Abstract Global Wallet now has session keys, allowing builders to create seamless apps where users sign once to transact without constant popups. Here's a demo of me creating a session key that allows mint me to mint NFTs without ever needing to sign another transaction. To build consumer crypto you need to create experiences that mimic existing web2 flows. Sessions are a huge unlock to bring us closer to that goal.

PSBT signing has never been this easy. Create the transaction with Sparrow Wallet 🐦. Sign on COLDCARD. No USB. No internet. Just a MicroSD. We’re giving away a COLDCARD Q to a Bitcoiner who replies with the moment they knew it was time to go airgapped.

On NDTV I said, Denying liberty to Umar and Sharjeel sends a chilling warning: challenge the state’s communal policies and this is your fate. First the chargesheet is delayed, then the trial never begins. Punishment without due process is a failure of the state.

A short video showing the signing capabilities using the new SpireKey wallet to one of our POCs on #Kadena. Big thanks to Albert Groothedde and the team for whipping together something we can quickly reference within Kadenajs. It's tough for me because all the wallets offer such a unique experience. Signing inside Linx dApp browser is still my favorite, Ecko is probably the most used dev wallet for good reason, and Koala looks really good/has ever-expanding options. Chainweaver on a Mac is slick, but otherwise, it's served a great purpose :). Great work to the entire Kadena ecosystem, change and innovation requires a lot of work. I look forward to seeing what the team does with #SpireKey and how we can test this and other wallets with existing merchants looking to dabble in web3.

Clear Signing and Transaction Checks are available for Aave! It’s simple, connect wallet to Aave using WC, then follow the steps in Ledger Live. On your device, you can verify exactly what you’re signing and even view the results of transaction simulations. Earn yield on your assets while keeping full self-custody and end-to-end security. If your favorite dApp is not yet clear-signed, simply ask them to add the support here. It's really easy for them.

The cat's out of the bag with the new TFTC: Sigbash v2 is live! We've switched to a new approach that I'm calling Oblivious Signing: using MuSig2, WebAssembly, and zero knowledge proofs, our signer never sees your signing key *or* the transactions you ask us to sign (!)

If the schools don’t want players signing contracts and then turning around and leaving, they need to create a system with real, enforceable rules. There is a way to do that, and they know it. They just don’t want to do it. Time to stop fighting.

for better understanding of how bitcoin works, i decided to build a fork called TETSUO. bitcoin uses secp256k1 ECDSA with SHA256/RIPEMD160 hashing for addresses and transaction signing. TETSUO maintains that exact same cryptographic foundation, we inherit decades of security research. but we optimized the transaction format: - sequence numbers set to 0xffffffff for full script compatibility - SIGHASH_ALL appended to the signing preimage before hashing (not after) - proper little-endian encoding throughout this meant rebuilding the entire signing pipeline. started by forking the bitcoin-core codebase, then built a complete TypeScript wallet SDK on top. implemented BIP39 mnemonic generation, UTXO selection, fee estimation, all the stuff wallets need. the critical part: client-side signing only. your private keys never touch any server. transaction is built locally, signed locally, broadcast to network. open source: (the node) (the SDK) (block explorer) understanding bitcoin meant understanding every layer of the protocol.

Next up, letter G: “Grammy Family Freestyle”/“Most Kingz”) #JayZ30 #JayZ Jay-Z: “I'm inspired by life and all sorts of things. You can say something right now, and it would inspire me to write a song. ‘Most Kingz’ just happened to be inspired by a Basquiat drawing. You know the drawing he had, the ‘most young kings get their heat cut off’ at the bottom, and I looked at that, and I was like, ‘It’s powerful.’ Just the statement ... lends itself for a song. ...It deals, for the most part, with success ... people you started your life off with and what success does to them. ...Then, it deals with the other side of success — how people look at you when you’re successful. ...Most kings get their head cut off in war, battle, in life. ...You’ve achieved everything you want. You’ve made it to the top of the throne, and at the end of the day, you just get your head cut off.”

What should your hardware wallet show you? When you sign a transaction or a message, what is the information you NEED to verify what you're signing is correct? If you don't know, you must watch this, and/or read this thread. 👇

Brian Windhorst mentions the Nuggets signing Demar Derozan & Timberwolves signing Jonthan Kuminga: "Watch the Wolves in the next couple days, I do think there's a possibility of Demar Derozan signing with the Nuggets. Shoutout to Chris Haynes. It's still open, there's still a window for the Lakers to do a Kuminga sign and trade. A sign and trade has to be 3 years. Now that these other doors are closing, the Tiimberwolves can close that deal and sign Kuminga." - Brian Windhorst

Derek Jeter shares a truth about failure that most people don't want to hear. "Failure is essential. If I can promise you one thing for certain, you will fail. I wouldn't have had the success without the failures." Failure isn't the opposite of success - it's part of the path to it. Successful people don't avoid adversity. They expect it. They know that they must learn from the setbacks and challenges. You can't avoid failure - you have to be relentless in your pursuits and refuse to let it stop you. Failure isn't a destination - it's a checkpoint. It's where growth begins. (🎥 MLive)
