Detailed description

NuCypher KMS is a decentralized Key Management System (KMS) that addresses the limitations of using consensus networks to securely store and manipulate private, encrypted data. It provides encryption and cryptographic access control, performed by a decentralized network, leveraging proxy re-encryption.

Unlike centralized KMS as a service solutions, it doesn’t require trusting a service provider. NuCypher KMS enables sharing of sensitive data for both decentralized and centralized applications, providing security infrastructure for applications from healthcare to identity management to decentralized content marketplaces. NuCypher KMS will be an essential part of decentralized applications, just as SSL/TLS is an essential part of every secure web application.

NuCypher is a data privacy layer for public blockchains and decentralized applications. It uses proxy re-encryption to provide decentralized key management and cryptographic access control services. It enables DApp developers to store, share, and manage private data on public blockchains. The NuCypher network is composed of nodes that provide re-encryption services. To operate a node and earn fees and mining rewards, you must stake the NuCypher token as collateral. This security deposit creates an economic incentive for nodes to behave appropriately and ensures correctness of computation. Also, the staked tokens are used to decentralize the network: one miner has only a fraction of the power to apply access policies, proportional to his stake.

NuCypher is led by its two founders MacLane Wilkison and Dr. Michael Egorov. MacLane has extensive experience in both software development and the financial services industry. Michael is former LinkedIn engineer and a former physicist and scientist from the Moscow Institute of Physics and Technology.


Public consensus networks, such as Bitcoin and Ethereum, are a promising solution to this centralization problem. But the limitations of public consensus networks in performing cryptographic operations that involve the manipulation of secret data are well-established. Consensus networks employ a volunteer network of nodes, which is subject to constant churn and not as reliable as central infrastructure when it comes to availability and enforcing access management rules.


NuCypher KMS uses a decentralized network to remove the reliance on central service providers, proxy re-encryption for cryptographic access control, and a token incentive mechanism to ensure reliability, availability, and correctness. Because of the use of proxy re-encryption, an unencrypted symmetric key (which gives the ability to decrypt private data) is never exposed server-side, and there is no single point of security failure. Even if compromised, hackers would only get re-encryption keys but access to the file is still protected.

    • Token symbol ? Token symbol — a shorten token name. It is used during an ICO and after the coin listing at the cryptocurrency exchanges. : NKMS
    • Fundrasing target ? Fundraising target — the maximum amount of funds to be raised during an ICO. When it is reached, the developers stop selling the tokens because they do not need to raise more money for the project development. : NA
    • Token type ? Token type — a platform for a startup launch that influences the stability of blockchain operation, the speed of transactions and the fees. :Ethereum (ERC20)
    • Soft cap ? Soft cap — the minimum amount of funds to be raised for the project development. Sometimes when the soft cap has not been reached, the money is returned to the participants. : NA
    • Role of token ? Role of Token — type of token depending on the opportunities it offers to its owner. Utility tokens give their owners a right to use the project services, security tokens are aimed at bringing profit, and currency tokens are a money substitute. :Utility token
    • Total supply ? Total supply — a total amount of tokens that will be released by the developers. :NA
    • Escrow agent ? Escrow agent — a qualified agent who has the right of signature in a multisig wallet. An escrow agent participates in an ICO, monitors the financial operations of the developers and confirms their fairness. :No
    • Tokens for sale ? Tokens for sale — the number of tokens offered to the participants of an ICO. :NA
    • Whitelist ? Whitelist — a list of participants, who get an opportunity to buy tokens. To be whitelisted, you need to register on time because the number of participants and the registration period are usually limited. :Without whitelist
    • Additional emission ? Additional emission — an additional release of tokens. It can be done once after the crowd sale or on an ongoing basis. In the projects with a limited emission there is no additional emission. :No
    • Exchange listing ? Exchange listing — an assumed date when the token will be listed at a cryptocurrency exchange. The developers usually indicate it in a roadmap and a white paper. :NA
    • Accepting currencies ? Accepting currencies — cryptocurrencies and fiat currencies that can be used for buying the project tokens. :ETH,
    • Can't participate ? Can't participate — the countries where it is prohibited to buy tokens. These can be countries where ICOs are prohibited altogether, or countries that have the requirements that a particular project does not meet. :No
    • Know Your Customer (KYC) ? Know Your Customer — a verification procedure for ICO participants, during which the developers can ask for personal data, a photo and a scanned copy of a passport of a potential investor. :Yes
