privacy (Why) Bringing Privacy to Smart Contracts is Non-trivial Private transactions are basically a solved problem for the consumer (although some challenges still remain for researchers). If we want to transfer cryptocurrency without revealing our balance or the transfer
NuBLS Threshold Signature Library We're excited to announce the release of NuBLS, a BLS signature library that implements threshold protocols like threshold signatures (TSS) and a Proxy Re-Signature (PRS) algorithm designed by NuCypher called
NuCypher WorkLock Update Thank you for participating in the NuCypher WorkLock! In total, 353,913 ETH (>$125M USD equivalent) was locked in the WorkLock smart contract by 2,011 nodes. CoinList escrowed
WorkLock: A Call to Action In the blockchain space we are constantly hearing the echoes of productivity and progress; incremental changes to the status quo that, at each step, remind us there exists a future
WorkLock Participation Details The WorkLock is finally here! The WorkLock is NuCypher’s novel network node setup mechanism that will be used to launch the network. It allows participants to temporarily stake ETH
To Work, or Not to Work - Accountability in the NuCypher Network In the land of NuCypher, there is a set of characters: Alice, Enrico, Bob, and Ursula. Currently, as one of the services that NuCypher provides, these characters work together to
Rethinking Service Systems: A Path Towards Secure and Equitable Resource Markets Net neutrality, equitable and monopoly-free ecosystems, decentralization and transparency, privacy and anti-censorship — these are some of the slogans we carry around when we think about the future of the Internet
An Intro to Fully Homomorphic Encryption for Engineers Fully homomorphic encryption is a fabled technology (at least in the cryptography community) that allows for arbitrary computation over encrypted data. With privacy as a major focus across tech, fully
DAO Announcing the NuCypher DAO We are excited to announce that governance in the NuCypher Network will be decentralized from genesis. To this end, we introduce the NuCypher DAO, a Decentralized Autonomous Organization to rule over the NuCypher Network
Blockchain Introducing "Sunscreen" One of our research areas is to create a secure, private, flexible smart contract scheme (“SPF,” hence the name “Sunscreen”). What initially started as a small(er) project to instantiate
From CASI to Mainnet Launch On January 15th 2020, NuCypher officially announced its Incentivized Testnet and challenged the public to Come and Stake It (CASI) and rise against the Silicon Valley merchants of infrastructure. CASI

Come and Stake It (CASI) Incentivized Testnet In 480 BC, at the Battle of Thermopylae, King Leonidas of Sparta rejected the Persian army's demand of surrender, instead challenging Xerxes and his mighty force to "Molon labe," or
privacy Today's kids need end-to-end encryption. Remember: the apocryphal ostrich who buries its head in the sand only thinks it can't be seen; it makes precisely the same mistake that we do when we plan our kids' daily routines in plaintext on servers owned by advertisers and snooped by states.
Blockchain ETHWaterloo2 Hackathon - Season Finale! What a busy few months it's been for us at NuCypher. After a stretch in Europe for ETHBerlin, Web3 Summit, and Berlin Blockchain Week, we parted ways before quickly reuniting
The Final Countdown: Public Testnet + Professional Staking Round Today, NuCypher enters the home stretch towards our long-awaited mainnet launch.
proxy re-encryption What exactly do we mean by access revocation? The topic of access revocation tends to be a confusing one in the context of encryption and data sharing. In our presentations, when we mention the ease of access revocation with proxy re-encryption as one of our sources of value...
Blockchain Three things that NuCypher's "Ursula" can do that vanilla public-key cryptography can't There are three good answers - and several more OK answers. This post will go through the three good answers and leave the reader to mull over the others.
