The Fairblock community never stops building and this one is worth paying attention to, ever been in a situation where you argued over a group bill before, who owes what, who already paid n all that. there are bill splitting apps, but there's a tradeoff, you give up control and transparency, which leaves us with on-chain tools been too transparent, but way too public for real life. @0xfairsplit is making it all different, built by @atomic_kurogane, Fairsplit is a USDC native expense splitter focused on the full flow, where you can create the bill, track payments, send reminders and get a clean on-chain record, everything is locked in via smart contracts, so no one can change the terms after. with fairsplit you don't get to choose between been fully public or hidden. Fairsplit lets you decide per transaction. Normal flow that is fully verifiable on-chain, built with @0xfairblock infrastructure to keep transactions confidential, so you pay your bills without exposing your business. Fairsplit is still early and its built to make on-chain payments stable, confidential and actually usable. Fairsplit is live on base sepolia, arc testnet and tempo testnet, so you can create and settle bills, or send funds directly confidentially if you want to test it, link in first comment





A common claim in crypto is that users don’t care about privacy. But the reality is more nuanced. What most users struggle with is 𝐜𝐨𝐦𝐩𝐥𝐞𝐱𝐢𝐭𝐲. 𝐖𝐡𝐚𝐭 𝐝𝐨 𝐈 𝐦𝐞𝐚𝐧?🧵


Congrats to the @tempo team on the mainnet launch! Fairblock enabled confidential stablecoin payments on the Tempo testnet from day one, and we're excited to bring confidential payroll, corporate treasury, merchant checkouts, and B2B payments to mainnet.

Lots of privacy chains / infra already built today but there's hardly anyone available building for the real world privacy contexts what most privacy projects did was pick one cryptographic tool and decided that it was enough to deal with the whole issue with exposure... practically simply forcing every privacy problem to work around it. ZK-proofs are pretty solid for verifying things without revealing them, but they mostly hide address links. your actual transaction amounts are still very visible. FHE can run computations on encrypted data which sounds insane, but it's so heavy it chokes past 50 TPS and usually needs a centralized machine just to function. TEEs lock sensitive stuff inside hardware enclaves until someone finds a way into the hardware. mixers hide everything, which is great until regulators show up. each of these tools does something real. the problem is pretending one of them does everything efficiently because the privacy problems you run into in the real world are not all the same problem. what am i talking about here ? • protecting a DeFi trade needs the transaction hidden before execution so bots can't front-run you, then fully visible after it settles. that's a timing problem. • encrypting payroll on-chain means doing math on salary amounts without ever exposing the actual numbers, not even briefly. that's a computation problem. • sharing some specific transaction details with a regulator while keeping everything else locked? that's a selective disclosure problem. three scenarios. three completely different requirements. one tool was never going to cover all of that cleanly. @0xfairblock carries the whole toolkit [IBE, FHE, MPC, ZK, TEEs, Witness Encryption] and the infrastructure figures out which combination fits the problem in front of it. ...NOT THE OTHER WAY AROUND. • so for the DeFi trade, IBE encrypts the transaction against a future block height. it's completely invisible in the mempool until the moment it executes, then it opens. bots see nothing. • for payroll, FHE lets the system verify amounts and process payments on encrypted numbers without ever decrypting them at any point. your salary never touches a public state. • and for the compliance scenario, MPC with IBE generates decryption keys scoped to specific auditors for specific transactions. the regulator sees what they're authorized to see, nothing else moves, and there's no master key sitting somewhere waiting to be exploited. same infrastructure, different combinations each time. that's the whole idea. a hospital, a trading desk, a DAO treasury, a payroll app -- they all need privacy but they don't need the same kind of privacy. building infrastructure that forces them all into the same cryptographic shape just means you've got blind spots. and blind spots are exactly where real world adoption dies every time. what most privacy projects did is build a hammer. Fairblock built a whole toolbox. for anything serious trying to bring privacy into production, that gap is going to start showing a lot more than people expect. so if you're building for privacy, you're better off building with @0xfairblock's privacy infra today
