robin linus robin linus stuff i like bitcoin a math based money anchored into physics a machine producing an incorruptible truth a solid foundation for healthy societies applied cryptography usability and scalability research open source software engineering product design development and simplicity some stuff i do bitvm compute anything on bitcoin shielded csv a high throughput shielded bitcoin protocol co authored with liam eagen and jonas nick of blockstream research the successor of my earlier work on zkcoins bitvm bridge bridging bitcoin to second layers a collaboration with matteo maffei and his security and privacy group at tu wien presented at the science of blockchain conference at berkeley this work received the bitcoin research prize 2025 bitvm3 efficient computation on bitcoin using garbled circuits bitvm 448 covenant based bitvm3 bridges zerosync a stark proof to verify bitcoin s chain state in an instant stakechains a bitcoin backed proof of stake algorithm based on one time schnorr signatures presented at codecfin 22 also co authored a research paper on this topic with david tse and his group at stanford university bitstream decentralized file hosting incentivised via bitcoin payments bitcoin poker heads up limit texas hold em on bitcoin with private dealing and on chain enforcement of the game rules vrf in the scalar a protocol for fair data exchange using a verifiable random function in the scalar binohash transaction introspection without softforks using bitcoin s variable length ecdsa der encoding as a side channel to read transactions in bitcoin script i am a ph d candidate at stanford university focusing on the scalability privacy and usability of bitcoin other stuff i did for fun bitcoin designing protocols on top of bitcoin such as improved stealth addresses light clients or an or operator for dlcs and ptlcs based on verifiable encryption some day peg betting on the activation of a two way peg bridging btc to other chains co created with burak and super testnet bitcoin dex backend is down a trading protocol based on non interactive atomic swaps using sighash_single a bitcoin spv client in solidity for a trustless two way peg between ethereum and bitcoin simple bitcoin web app usability research on key management using secure key generation from email and password via a warpwallet and storing credentials in the browser s password manager a related work is secure bookmarks co created with egor homakov exotic bitcoin scripts such as tictactoe in a schnorr signature or nondeterministic programming op_cat magic such as emulating covenants using ecdsa emulating ec multiplication and exploring evil covenants dark skippy a novel mechanism for key exfiltration attacks co created with lloyd fournier and nick farrow mechanisms for replay protection based on dust inputs or reserved nlocktime implemented by ecash com script wizardry a selection of my love letters to satoshi s bitcoin script the first sha2 ecdsa polyglot a sha2 hash which is simultanously a valid signature the first binohash script transaction introspection without a softfork the first bitvm2 challenge demo the first blake3 implementation in bitcoin script side projects snapdrop share files on your local network had millions of monthly users since its launch in 2016 raised awareness for known privacy issues in browsers and web platforms e g github stackoverflow instagram to create public awareness to fix them e g webkay and social media leak discovered security bugs in major software products and received bug bounties from companies like google twitter and apple media a list of talks podcasts and interviews i have appeared on github twitter
