Published August 2021

mobile-pdf-preview

The Orbs project is launching a new call for grants under the OEGP. For this round, the focus will be on applications that will draw on the power of the Orbs Universe, with its Guardians and Delegators, using their ability to arrive at consensus through the Orbs protocol incentive layer powered by the ORBS token.

Use of Ethereum as a Base Layer for PoS and PoA Platforms

Published February 2019

mobile-pdf-preview

We designed Orbs for applications that make use of multiple blockchain platforms (i.e. a hybrid system) because we believe such design makes more sense for complex, real-world use cases. In this paper, we would like to highlight some of the advantages and challenges hybrid designs can bring to infrastructure projects.

Eliminating the Security-vs-Scalability Dilemma: Randomized-Committee Consensus Protocols

Published August 2018

mobile-pdf-preview

Current-generation blockchain protocols can determine their level of decentralization on an security-performance spectrum. A new family of consensus protocols enable the maximization of both security and throughput by employing novel cryptographic techniques for trustlessly generating random seeds in a group, without allowing any party to manipulate or predict the randomization results.

Blockchain Architecture Considerations to Compete with PaaS/Cloud Services

Published August 2018

mobile-pdf-preview

In this document we present our findings, along with some architecture designs that may be used to create a blockchain platform that is competitive with centralized platforms. These aspects include cost structures, system performance when scaling up, avoidance of platform lock-ins to reduce technical risks, and completeness of the smart contracts environment.

Fully Distributed Group Signatures

Published April 2019

mobile-pdf-preview

A group signature scheme is a powerful primitive by which one can sign a message as a member of a well-defined group without leaking one’s individual identity, but the group manager can revoke this anonymity and reveal the identity of the signer. We present two highly efficient fully distributed group signature schemes in this paper.

Rational Threshold Cryptosystems

Published January 2019

mobile-pdf-preview

We propose a framework for threshold cryptosystems under a permissionless-economic model in which the participants are rational profit-maximizing entities. The key threat to rational threshold cryptosystems is collusion—by cooperating `illegally’, a subset of participants can reveal the cryptosystem’s secret, which, in turn is translated to unfair profit. Our countermeasure to collusion is framing.

Orbs Operation Fees

Published March 2019

This list of operation fees provides the specifics of how the overall vision of stable and predictable operation fees will be implemented in the Orbs network. The goal of predictability is accomplished because the purchasing power of ORBS tokens is fixed as equal to a defined amount of computing power.
