NuCypher Blog -> Threshold Blog

In an attempt to move our reader base over to Threshold's blog I am providing this quick summary and link here: Wait, what is Threshold?? Threshold Network is the first ever on-chain merge between two existing networks and communities, Keep and NuCypher. Threshold provides a suite of threshold cryptography products

Developer Update - Abiotic Alice and DKG (October 2021)

NuCypher's proxy re-encryption (PRE) service is leveling up. Recently, the demand for access-conditioned content in Web3 has exploded: subscriptions, streaming, private NFTs, NFTs as access tokens, the list goes on. Many of those are building on NuCypher (soon Threshold!) and proxy re-encryption. For example: Masterfile is building an enterprise NFT

NuCypher Community Update - September 2021

Once a month we'll be putting out community updates in the format of team member interviews. September's update is an interview NuCypher's CTO, David Nuñez.

NuCypher + Keep: KEaNU AMA, Hosted by Staking Hub

Hey NuCypher and Keep community, here is the transcribed copy of the AMA hosted by Figment's Staking Hub. Thanks to the hosts, the Nu + Keep team, and those who asked questions from the community.

KEaNU is a Go

On Friday, June 11, the snapshot signal for Proposal RC0, was approved by NuCypher stakers and tokenholders. Proposal RC0 received unanimous support from NuCypher stakers and tokenholders.The proposal received unanimous support on the NuCypher side. It was simultaneously approved on the Keep side, which means the first-ever on-chain network

An Intro to tBTC for NuCypherinos

Perhaps the most overlooked aspect of NuCypher's collaboration with Keep is the upcoming launch of tBTC v2. Bitcoin and DeFiIn crypto, BTC is the king. With a network value of >$1 trillion, BTC is the OG cryptoasset and currently has the most mainstream credibility and institutional interest, largely driven

Codename KEANU

A proposal for the first-ever decentralized, on-chain network hard merge between Keep and NuCypher.

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 amount, we have acceptable options available like Zcash and Monero. The same cannot be said for private decentralized applications or

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 Penumbral (paper in-progress). The Python wrapper is installable with pip as pynubls and the core Rust library is accessible from

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 147,465 ETH on behalf of 3,685 participants and will be running 8 nodes on the network. This result

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 molded by those who believe in an alternative one. A future where privacy is held higher than a right, where

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 in order to receive NU for the exclusive purpose of running a NuCypher network node. Key Details/TLDRWorkLock escrow period:

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 implement a decentralized access control service (or key management system). In particular, Alice owns some data that is stored encrypted

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 and its digital services. We dream of flexible systems that allow anyone, from anywhere, to obtain or provide a service

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 homomorphic encryption (FHE) fits perfectly into this new narrative. FHE is relevant to public distributed ledgers (such as blockchain) and

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

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 private smart contracts on Ethereum has become much more ambitious once we realized we cannot achieve our vision for a

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 kicked off on January 20th and comprised of 3 (eventually 4) Phases designed to test various parts of the network

University Staking Partners

We’re excited to announce a novel experiment: our University Staking Program. This is a strategic agreement with a select group of Computer Science departments and Cryptography labs at eleven universities around the globe. The program accounts for 1.95% of the initial NU token supply, giving the participating universities

CASI Phase 4 Tasks

OverviewPhase 4 will be another trial run of the WorkLock token distribution mechanism with some tweaks and improvements based on our learnings from Phase 3. Once again, you'll contribute Goerli ETH (goETH) in exchange for stake-locked Goerli NU (goNU) tokens which you can use to run a node and recover

Welcoming Ghada Almashaqbeh

We're very pleased to share that Ghada Almashaqbeh has joined the NuCypher research team! Ghada Almashaqbeh, PhDGhada completed her PhD in Computer Science from Columbia University in Spring 2019, where she was a member of the Cryptography Lab and the Data Science Institute. Her research interests cover cryptography, security, privacy,

CASI Phase 3 Tasks

Phase 1 (Core Staking & Node Operations): Done ✅ Phase 2 (Advanced Staking & Node Operations): Done ✅ Excellent work NuCypherinos! Now, it's time for WorkLock! OverviewPhase 3 will be a test run of the WorkLock token distribution mechanism. You'll learn how to contribute Goerli ETH (goETH) in exchange for stake-locked Goerli

WorkLock Security Audit

From January 13 through 17, we engaged Trail of Bits to audit the WorkLock smart contract (along with various smart contract size optimizations). As a reminder, the WorkLock is our intended distribution mechanism for the NuCypher token. It provides a way for stakers and node operators to receive NU in

CASI Phase 2 Tasks

Whew, congrats on finishing the Phase 1 tasks! You've evolved from a Nuub into a grizzled NuCypherino and are ready for Phase 2 (Advanced Staking & Node Operations), which will last until February 17! Note: If you struggled with Phase 1, we highly recommend you consider delegating to one of
