Community Update #3
Seattle. — (Credit goes to jMyles for the documentation) The NuCypher team gathered in Seattle, Washington, USA for a 10-day collaboration earlier this month (February 2018). We rented a house on the east side of the city and lived and worked together for each of these days. In attendance were (alphabetical by Discord handle) Arj, jMyles, KPrasch, Maclane, Michwill, Ryan, and Tux. Notable mentions to KPrasch’s partner Gabby and jMyles’ partner Chelsea and their 2.5-year old, Fibonacci, for attending parts of the gathering. The team undertook a wide array of errands during our ten-day sprint. The tasks accomplished include building new features for NuCypher’s KMS, discussing and implementing new security standards and anti-scam/spam measures, and moving our team communications from Slack to Discord (join us!). Lastly, a significant milestone was completing and implementing pyUmbral, our reference implementation of the proxy re-encryption on which our entire ecosystem depends. Our codebases saw a total of 268 new commits, including more than 1,200 new lines introduced into our KMS project. Perhaps equally impressive is the removal of over 3,000 lines (“redlines”) by the coordinated efforts of our team. We’ve received several requests from the community about having further information about NuCypher team members, so we also conducted interviews — these will be available soon on our website (and perhaps ...

Community Update #2
Keeping you in the loop. — — Developer Updates. — Our engineering team has been hard at work building out the NuCypher protocol. For detailed technical discussions join our Slack or follow along on GitHub, but here are the highlights:Implemented a Data Encryption Mechanism (DEM) that allows users to encrypt data using the Umbral scheme and protect it with authenticated encryption (ChaCha20-Poly1305).Serialization of all Umbral artifacts (keys, ciphertexts, etc.)Simple API Construction — a simple API has been implemented to allow users of Umbral to easily use and handle proxy re-encryption without messy or otherwise complicated code. This also contributes to product readability quite a bit.Improved tests to validate the security of our scheme against known standards — Upcoming Changes. — Further security hardeningMore Proxy Re-encryption API improvements to readability, usability, and documentationNuCypher Event Rundown — NuCypher & THE COIN + Tokyo Meetup. — NuCypher was at THE COIN & Smart Contract Meetup in Japan this month — filled with great keynotes, projects and community building.

First few weeks of 2018. — At NuCypher we’re so excited to share with you our recent updates, growth, questions, & content — Developer Updates. — Our engineering team has been hard at work building out the NuCypher protocol. For detailed technical discussions join our Slack or follow along on GitHub, but here are the highlights:Moving from academic reference implementation to engineering a hardened and functional schemeSide channel resistance added inBuilt a miniature framework on top of OpenSSL and Cryptography.io to assist us in building Umbral. You can see some of our work in bignum.py and point.pySecure erasing of memory when private keys are used in OpenSSL. When this cryptography.io release goes out, we will do the same to UmbralImplemented our challenge protocol into the schema itself! This allows nodes to validate and prove that they are doing their job correctly which is a huge step for increasing the security of the NuCypher KMS network — Upcoming Changes. — Separating out encryption/decryption/re-encryption code based on how it’s used on the network. This will increase readability and audibility of the codeOperations changes — we’re going to update the “mini framework” to use more proper academic notation for enhanced readabilityImproved and more standardized serializationVarious readability changesSecurity hardening — NuCypher & WCEF 2018. — ...

MediBloc Leverages NuCypher for its Blockchain-based Healthcare Information Ecosystem
MediBloc, an open-source healthcare data platform, is leveraging the Qtum blockchain, IPFS, and NuCypher KMS, to create a Patient-controlled electronic Health Records (PHR) system. MediBloc’s mission is to give the ownership of health information back to patients, allowing the rightful owners of health data to both keep their data private and monetize it in various ways. The MediBloc platform will also incentivize healthcare providers, insurers, researchers, and pharmaceutical companies to participate and contribute to a new blockchain-based ecosystem using Medi Token (MED).Technical Requirements One of the key requirements for architecting any PHR platform is ensuring the confidentiality of medical information. Storing unencrypted medical records on IPFS exposes patients to possible repercussions, including social stigma associated with certain medical conditions or financial hardship due to difficulties in securing insurance coverage and loss of employment. Achieving confidentiality of records stored on IPFS — which is, by definition, public — while maintaining the ability to share those records with appropriate medical providers, is a fundamentally difficult problem. Simply storing encrypting records in IPFS is insufficient as there must be some mechanism to provide access to the patient’s medical provider. In MediBloc, there are three primary actors who require access to private data:Patients — the...

 | Privacy Coins Take a Beating This Year Losing Over $6 Billion, Anonymity...
The last 12 months have been tough on digital currency investors as the crypto winter has caused a large sum of value to leave the once-bustling economy. The privacy coin economy, for instance, shed more than 55% against the U.S. dollar as it dropped from $11.7 billion in Jan. 2022 to the current $5.22 billion.Privacy Economy Loses 55% Against the Greenback, European Union Looks to Ban Anonymizing Cryptos
Privacy coins are not talked about like they used to be. These days, the hype and discussions surrounding decentralized finance (defi) and non-fungible tokens (NFTs) have eclipsed privacy coin conversations.
Furthermore, during the last 12 months, the privacy coin economy has dropped from $11.7 billion to today's $5.22 billion. Last January, the top two privacy tokens included monero (XMR) and zcash (ZEC).
At the time, monero was the largest privacy coin by market cap and still is today. In Jan. 2022, XMR's price was around $202.97 per unit and it had a market valuation of around $3.66 billion on Jan. 19, 2022.
Today, XMR is exchanging hands for around $142.35 per coin and it has an overall market capitalization of around $2.58 billion. Zcash holds the second-largest privacy coin market valuation this year and in January it was around $1.53 billion.
At the end of Dec. 2022, ZEC's market cap is down to $517 million. Jan. 2022's top five privacy coins by market cap included monero (XMR), zcash (ZEC), secret (SCRT), decred (DCR), and horizen (ZEN).

|  | The Top Privacy Coins Saw Fewer Percentage Losses Than Most Tokens This ...
The privacy coins monero and zcash managed to see fewer percentage losses against the U.S. dollar this week, in contrast to crypto assets like bitcoin, ethereum, and solana. Seven-day statistics indicate zcash has lost 5.6% against the USD, while monero dropped by 6.1%.Privacy Coins Manage to Stave off Some of This Week's Market Carnage, but Are Still Down 62% Lower Than 9 Months Ago
At the time of writing, the entire market capitalization of all the privacy coins in existence is roughly $5.55 billion. Monero (XMR) leads the pack with a market valuation of around $2.64 billion or 47.5% of the entire privacy coin economy. Zcash (ZEC) is the second largest privacy coin in terms of market capitalization as ZEC's overall market valuation today is $789 million.
Behind XMR and ZEC, are privacy tokens such as decred (DCR), nucypher (NU), secret (SCRT), horizen (ZEN), ergo (ERG), digibyte (DGB), and beldex (BDX), respectively. Top privacy coin double-digit gainers this week include deeponion (ONION), litecash (CASH), pivx (PIVX), and masari (MSR). The week's top privacy coin losers in terms of percentage losses include tokens like zclassic (ZCL), lethean (LTHN), and phore (PHR).
The top five privacy coin crypto assets make up most of the $5.55 billion in privacy coin value, and each token offers different types of privacy techniques. XMR is a Cryptonote token with a blockchain protocol that was not forked from Bitcoin. XMR uses ring signatures, ring confidential transactions, steal...
