Can Circle see inside private transactions on Arc? Nikhil Chandhok, Circle’s Chief Product & Technology Officer: “Validators are not gonna be able to look at your transactions.” “Nobody’s able to look inside those.” “Even Circle cannot look inside those transactions.” “When I say privacy, it’s true privacy.” “Privacy is... show more

@circle @arc @chandhok private rails are nice, but public ledgers still need a privacy patch.

@circle @arc @chandhok privacy sounds good, but the Lazarus test is where Arc has to earn it

Mert on why privacy is making a comeback in crypto "When I first started talking about Zcash it was at $18, and privacy was literally deemed dead in crypto. It wasn't mentioned anywhere. Now look, privacy protocols across every ecosystem are getting funded" "Near is adding confidential transfers. Base just added private transactions. I'm adding private transactions to Solana. The whole space is moving this way" "Privacy is fundamentally a positive for the individual. It gives you more freedom, more choice, more dignity onchain. Instead of getting surveilled for the rest of your life. It's not all zero sum"

"The way they achieve their private transactions is exactly the trust me bro, there's a sequencer who has a reputation and you send all your transactions to that sequencer" Aztec Labs CEO Joe Andrews on why Canton's privacy is just trusting an intermediary, not real cryptographic privacy "It's what I touched on earlier, privacy through intermediaries versus cryptographic privacy. The way they achieve their private stablecoins or private transactions is exactly the trust me bro, there's a sequencer who has a reputation, and you send all your transactions to that sequencer and trust, with a non-credible commitment, that they're not going to monetize that data or sell it to anyone" "So while it jumps on the privacy bandwagon, it's basically a bunch of banks trying to adopt a different tech stack" "I think it should come out in the wash, at least for these use cases that require strong credible commitments and actual privacy that's backed by cryptographic guarantees"

"People claim that users don't ultimately care about privacy. That may be true when it comes to some of the more incidental data about their lives. But I don't believe it is true when it comes to finance." on why crypto needs privacy to become mainstream: "In order for crypto to actually become mainstream and to be used for real applications, it's going to have to have privacy. People will care that their salary is not visible to everyone. They will care that the transactions they make online are not visible to everyone."

Private transactions between wallets now possible on Solana using ZERAs Private Cash Addresses. A closer look at last week’s MVP drop: Private P2P. Most "privacy" on Solana still falls back to withdraw-to-address (recipient + metadata leaks) or multi-step send flows that leave trails. Our P2P is different: one atomic in-pool transaction, the sender’s note is nullified, and two new encrypted notes are created, all inside the vault. No stepping out. No re-deposit choreography. Why it’s so hard to deanonymize: ✅ Your Private Cash Address has zero link to your Solana wallet: it’s an X25519 keypair derived from a wallet signature, and the public key becomes your private address. ✅ Notes are encrypted with NaCl box using a fresh ephemeral key every send, meaning even two payments to the same person looks unrelated. ✅ Recipients discover incoming notes via trial decryption, the chain never learns "who owns what." While we have immense respect for those building privacy on Solana, we are proud to be the first to achieve one-shot, in-pool P2P with full privacy. To our knowledge, this remains an industry first. This is the difference between hiding balances inside a pool and moving value privately between people. Note: Right now, the sender’s wallet still signs the private transaction, so on-chain you can see that a wallet performed a P2P action, but the amount and recipient remain private. The upcoming P2P Relayer removes that footprint too, completing the "cash-style" flow with no on-chain sender trace. What’s coming next: ✅ More assets: At least SOL + ZERA alongside USDC. ✅ P2P Relayer: A decentralized signing/relaying network that can submit transactions for you — enabling withdrawals with minimal linkage after the initial deposit, and removing the sender’s on-chain P2P footprint. Try it out in the ZERA Dashboard below ⤵️

🚨 CRYPTO SCAMS EXPLODE INSIDE CIRCLE K STORES - VICTIMS SAY LIFE SAVINGS VANISHED AT BITCOIN ATMS A CNN investigation just exposed what employees describe as an “open secret” inside Circle K locations nationwide. Customers are targeted by scammers and walked step-by-step to crypto ATMs inside the stores, often while being told on the phone not to hang up. You can hear the officer pleading with one potential victim: "He's scamming you out of your money. So we're trying to prevent that and stop you from doing it. He's gonna take your life savings from you. Don't let him do that." CNN and the ICIJ reviewed 150+ scam cases tied to crypto ATMs operating inside Circle K stores. The machines are owned by Bitcoin Depot, the largest crypto ATM operator in the U.S. Circle K is its largest corporate partner. Employees say management knew. The machines stayed. And the deal was renewed anyway. Once the cash goes in, it’s gone. How is this even allowed?

"You're BlackRock and you send JP Morgan money from one bank account to another. Would you want everybody to be able to see that?" "A lot of these chains, seeing the success of Canton and others, realize that institutions are not going to participate in crypto unless privacy is a given. Privacy, or we could even call it confidentiality in this case, like developing confidential transfers" "The problem with public blockchains is that you may not know it's my bank account and your bank account, but everybody can see where some money was sent, and with any decent onchain analysis, probably tie that to you. Institutions can't do that. The largest institutions on the planet need to know their transactions are completely confidential" "Ethereum Foundation researchers are launching an institutional grade privacy system called ETH Systems. They're developing confidential transfers, private bond issuance, privacy preserving identity, and confidential settlement systems designed specifically for institutional users"

"We just announced something called Circle Nano Payments. It's a module for agents to be able to have a stored balance of digital dollars—tokenized dollars—and be able to transact them to different wallets on different blockchains." "We've gotten it to the point where we can actually have transactions priced at one-millionth of a penny per transaction."

"With Monero, you're trying to hide amongst a bunch of fake transactions" Multicoin co-founder Tushar Jain on why Monero's privacy model is more at risk from AI than Zcash's "The Monero comparison is interesting, but Monero doesn't provide the same level of privacy guarantees that Zcash does." "Monero uses ring signatures, which is a type of obfuscation of privacy, whereas Zcash uses zero knowledge proofs. So the information on Zcash is just not even out there, it is not visible to the public." "I believe that as AI powered data analysis tools get more powerful, it puts that privacy model more at risk, and that is problematic."

KnoxNet Mobile-App First Look We’re sharing an early look at the $KNX mobile app and how users will interact with it. This preview shows the core flow ,from secure setup and vault creation to how value is managed inside the app. More importantly, this is the first look at how offline transfer of money will work on KnoxNet. Users will be able to generate, store, and transfer value locally through Offline Notes, without relying on an active internet connection. While the experience is simple on the surface, the system handles escrow, issuance, and state tracking in the background. KnoxNet is redefining privacy. True privacy begins when the internet shuts down and no one is watching. Reconciliation can be triggered when needed to sync with the global ledger, ensuring consistency without forcing constant connectivity. This is still an early build, Stay tuned for more updates.

Every digital payment leaves a trail: who got paid, where you were, when and how often. On its own it looks harmless. Stacked up, it’s a behavioral profile that’s searchable, monetizable and rarely private. A new Cointelegraph x Aleo deep dive breaks down what your everyday transactions are actually revealing, and why privacy needs to be built in, not patched on.
