Composition and combinationâbased object trust evaluation for knowledge management in virtual organizations
Purpose
â This paper aims to develop a framework for object trust evaluation and related object trust principles to facilitate knowledge management in a virtual organization. It proposes systematic methods to quantify the trust of an object and defines the concept of object trust management. The study aims to expand the domain of subject trust to object trust evaluation in terms of whether an object is correct and accurate in expressing a topic or issue and whether the object is secure and safe to execute (in the case of an executable program). By providing theoretical and empirical insights about object trust composition and combination, this research facilitates better knowledge identification, creation, evaluation, and distribution.
Design/methodology/approach
This paper presents two object trust principles â trust composition and trust combination. These principles provide formal methodologies and guidelines to assess whether an object has the required level of quality and security features (hence it is trustworthy). The paper uses a componentâbased approach to evaluate the quality and security of an object. Formal approaches and algorithms have been developed to assess the trustworthiness of an object in different cases.
Findings
The paper provides qualitative and quantitative analysis about how object trust can be composed and combined. Novel mechanisms have been developed to help users evaluate the quality and security features of available objects.
Originality/value
This effort fulfills an identified need to address the challenging issue of evaluating the trustworthiness of an object (e.g. a software program, a file, or other type of knowledge element) in a looselyâcoupled system such as a virtual organization. It is the first of its kind to formally define object trust management and study object trust evaluation
KRNC: New Foundations for Permissionless Byzantine Consensus and Global Monetary Stability
This paper applies biomimetic engineering to the problem of permissionless
Byzantine consensus and achieves results that surpass the prior state of the
art by four orders of magnitude. It introduces a biologically inspired
asymmetric Sybil-resistance mechanism, Proof-of-Balance, which can replace
symmetric Proof-of-Work and Proof-of-Stake weighting schemes.
The biomimetic mechanism is incorporated into a permissionless blockchain
protocol, Key Retroactivity Network Consensus ("KRNC"), which delivers ~40,000
times the security and speed of today's decentralized ledgers. KRNC allows the
fiat money that the public already owns to be upgraded with cryptographic
inflation protection, eliminating the problems inherent in bootstrapping new
currencies like Bitcoin and Ethereum.
The paper includes two independently significant contributions to the
literature. First, it replaces the non-structural axioms invoked in prior work
with a new formal method for reasoning about trust, liveness, and safety from
first principles. Second, it demonstrates how two previously overlooked
exploits, book-prize attacks and pseudo-transfer attacks, collectively
undermine the security guarantees of all prior permissionless ledgers.Comment: 104 page
