Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

Hashing It Out #26: NuFHE – Michael Egorov and John “Tux” Pacific

Episode 26
October 10, 2018 — 59 mins
Guests: Michael Egorov & John Pacific

Great Caesar’s Ghost! NuCypher has demo’d a practical fully-homomorphic encryption (FHE) scheme that leverages an Ethereum smart contract for a proof mechanism. We get to go over FHE: what it is, how it works, how it commits to the blockchain, scaling issues, and the future of encrypted computation. This will enable new privacy mechanisms on layer 2 solutions which interface with the blockchain cheaply and efficiently. Very big stuff for anyone trying to use blockchain as a resolution mechanism but wants to hide their business rules in the process!

Access control for real-world data, generated by real-world humans

We are asked frequently about real world use cases for NuCypher... So @tbitls put together this case study which maps NuCypher capabilities to real user objectives.

Case study: A network of on-the-ground Dataeum collectors continually generates valuable real-world data, selling on to location-based services (e.g. Yelp, Waze). A partner network of NuCypher proxies manages permissions, protects collector privacy, and enforces compensation.

I have never runned a node before, but for sure I'm willing to, you guys will give us some tutorial/help to configure it?

Yes, we'll be providing recommended instructions for how to install, configure, and maintain a node(s).
Does it mean that only people who installed the node can participate in your crowd sale? or they will have better conditions like a bigger personal cap etc. ?
And where can i find the instruction for installation on mac?

TBD on whether you will be required to run a node to participate in the sale or not.

We will be publishing documentation on installing, configuring, and maintaining a node once the testnet is up in the next few weeks.

Good, waiting for updates, thank you Maclayne.
And when this conclusion will be accessible: "Solidity smart contract and network code audit from Least Authority and Trail of Bits."

The NCC Group audit of the Umbral cryptosystem is complete and we'll be publishing the report soon.

The Least Authority and Trail of Bits audits are still in progress. They'll be completed in the next month or so, and the reports will be published afterwards.


Publish the results here please, i think a lot of users will be happy to read it and i'm pretty sure that everything will be ok in that reports and you will have a bit more project fans here:)

Here are the reports from Trail of Bits and NCC Group: https://blog.nucypher.com/security-audits-round-1-c662bdf957c

Not all the tokens have been sold. There will be a public distribution when mainnet goes live.

When it will happens? And how much you provide for a public sale?

We're working towards a summer mainnet launch, which is when the tokens will go out as well.

This project very well it can help us control access to encrypted easy and whenever and where. I'm very pleased about it and people too.

it gives us many benefits in use. before I did not see this. I will use this service. it is made qualitatively



BIG WINNER!

NuCypher KMS: Decentralized key management system

We’re excited to share NuCypher KMS, a decentralized key management system (KMS) for public blockchains. With NuCypher KMS, an entirely new set of decentralized applications is unlocked for developers. Use cases requiring secure storage, sharing, and manipulation of private data can now be built on public blockchains, allowing for greater protection and control of private data.
The post below gives an overview and a detailed description can be found in our draft technical white paper.

What
NuCypher KMS provides encryption and cryptographic access controls, without reliance on a central service provider. It leverages state-of-the-art proxy re-encryption technology to allow re-keying encrypted data. This allows a decentralized network of nodes to provide key management operations, without accessing private keys or plaintext data.

How
The core technology is proxy re-encryption (PRE), a cryptographic primitive which allows a third-party proxy to transform ciphertexts from one public key to another (using re-encryption keys), without learning anything about the underlying message.

Main actors and interactions in a PRE environment
This ability to securely delegate access to private, encrypted information, makes PRE an ideal candidate for constructing cryptographic access controls for distributed systems such as blockchain, internet of things (IoT), and big data.
In NuCypher KMS, access controls are issued, enforced, and revoked via smart contracts executed by a decentralized network of re-encryption nodes. This network controls re-encryption keys and allows data owners to conditionally grant and revoke access to third-parties based on their public key.
Re-encryption nodes are incentivized to behave properly using a proof-of-stake NKMS token. If the nodes are malicious or defective, their deposit is forfeit. Correctly behaving nodes are incentivized to provide re-encryption services through payment in NKMS.

Use cases
NuCypher KMS enables public blockchains to securely store and manipulate secrets, giving decentralized applications a way to work with private data. But key management as a service is useful for centralized applications, too.
Potential use cases include:
  • KMS-as-a-service for handling secrets in AWS instances (similar to Hashicorp Vault, Amazon Key Management etc);
  • Safely storing encrypted secrets alongside code on GitHub;
  • Decentralized Digital Rights Management (DDRM);
  • Pay-to-view streaming;
  • Encrypted digital content marketplaces;
  • Private multi-user chats;
  • Private, shareable file storage;
  • Patients sharing medical records with healthcare providers;
  • Blind identity management;
  • Mobile device management and revocation.

Call for contributions
We’re very interested in the community’s suggestions and comments on the technical white paper — everything from security to token economics to functionality requests. We’re also excited to brainstorm use cases for NKMS and would love to hear your ideas. Your involvement will help inform the final, revised version of the white paper.

You can find a draft of the technical white paper and the GitHub repo.

Join our NuCypher KMS community. We look forward to answering your questions on:
