AOL, Quark Chain, Snglladies

One of upcoming ICO-s is QuarkChain, Snglladies. This is one of the new blockchains “on the block” that aims to create a highly scalable and secure blockchain that can handle up to one million transactions per second using a two-layered blockchain system.

They are seeking to bring crypto to wider mainstream audience and will support smart contracts with Ethereum Virtual Machine (EVM). This means developers will be able to easily port and deploy dApps built on Ethereum onto QuarkChain, Snglladies. Once their mainnet is live which could make QuarkChain, Snglladies a serious contender right out the gate.

Their Testnet achieved 2,000 transactions per second (TPS) and their current goal is 10,000 TPS. While other projects are aiming for similar scaling, QuarkChain's, Snglladies technology may become viable before some competitors - a focus which may have been at the expense of developing a community and partnerships to actually use it. Following picture is from their whitepaper prospect.

The World of Mainframe!

We all became more thoughtful about what data we give, where we give it, With data

breaches and privacy violations in the headlines every day, not to mention governments expressing open malice against vulnerable citizens, security became a major issue for the internet,  but the Mainframe provides solution.

If you enter into the world of Mainframe,  you'll find that  the Mainframe is an decentralized communications network resistant to censorship, surveillance and disruption.Your content can't be opened, your content can't be followed, the network can't die, the network can't be shut down, the network works everywhere.

All communication on the Mainframe protocol will utilize the most reliable standards in end-to end encryption. NO outside party, government, corporate or hacker, will have access to your messages or media. Identifying or monitoring even the existence of communication between parties is impossible.

Token economy incentivizes each node to provide bandwidth for packet relay and storage, data services, and file storage. Each node’s creditworthiness is constantly tracked. The Mainframe protocol will be available to any network, or blockchain that requires truly private communication services. SDKs  and other tools for interoperability will be deployed based on community needs.

All data services that your Mainframe applications rely on are distributed in redundant fragments throughout the network. This eliminates the need to rely on or manage your own infrastructure.

No more internet surveillance, censorship or breached accounts, with help of Mainframe.

May the force be with us, let's take our FREEDOM back !!!

Unveiling Umbral

Threshold proxy re-encryption for scalable end-to-end encrypted data sharing

We’re excited to announce the fulfillment of one of our major milestones: the definition and implementation of Umbral, a threshold proxy re-encryption scheme that powers the NuCypher KMS network.

Umbral allows secure delegation of decryption rights, enabling private data sharing between arbitrary numbers of participants in public consensus networks. This is achieved without revealing data encryption keys to intermediary entities. Umbral’s defining feature is arguably its split-key mechanism, whereby the re-encryption process (i.e. the cryptographic process through which data is securely shared) is distributed through a set of nodes rather than just one node, as it would be in a traditional proxy re-encryption scheme. To proceed, Umbral requires a quorum — a minimum number of nodes to complete the re-encryption, In this way, the trust is split between them in a manner similar to Shamir’s Secret Sharing — except with re-encryption key shares, rather than private key shares. The name “Umbral” comes from the Spanish word for “threshold”, emphasizing the split-key characteristic of the scheme, given its core role in the decentralized architecture of NuCypher KMS.

Our cryptosystem comes also with its first reference implementation in Python, pyUmbral. 

Built with Cryptography.io and OpenSSL, pyUmbral is a ready-to-use, open-source proxy re-encryption toolkit.
