k-root-n: An efficient O(√n) algorithm for avoiding short term double spending in Distributed Ledger Technologies such as Blockchain
Blockchain bitcoin distributed ledger technology
2019/7/17
Blockchains such as bitcoin rely on reaching global consensus for the distributed ledger, and suffer from a well know scalability problem. We propose an algorithm which can avoid double spending in th...
Public Ledger for Sensitive Data
Privacy-Preserving Ledger Blockchain End to End Encryption
2019/6/19
In this work an original protocol is presented that allows sensitive data to be stored on a ledger where its integrity may be publicly verified, but its privacy is preserved and owners can tightly man...
Contingent payments on a public ledger: models and reductions for automated verification
fair exchange security models blockchain
2019/5/9
We study protocols that rely on a public ledger infrastructure, concentrating on protocols for zero-knowledge contingent payment, whose security properties combine diverse notions of fairness and priv...
DAGsim: Simulation of DAG-based distributed ledger protocols

2018/11/12
Scalability of distributed ledgers is a key adoption factor. As an alternative to blockchain-based protocols, directed acyclic graph (DAG) protocols are proposed with the intention to allow a higher v...
Ledger Design Language: Towards Formal Reasoning and Implementation for Public Ledgers

2018/5/11
Cryptocurrencies have popularized public ledgers, known colloquially as "blockchains". While the Bitcoin blockchain is relatively simple to reason about as, effectively, a hash chain, more complex pub...
Hidden in Plain Sight: Storing and Managing Secrets on a Public Ledger
blockchain decentralisation access control
2018/3/5
Current blockchain systems are incapable of holding sensitive data securely on their public ledger while supporting accountability of data access requests and revocability of data access rights. Inste...
OmniLedger: A Secure, Scale-Out, Decentralized Ledger
Blockchains Scale-Out Decentralization
2017/5/12
Designing a secure and open Distributed Ledger (DL) system that performs on par with classic payment-service providers such as Visa is a challenging task. Current proposals either do not scale-out or ...
Solidus: Confidential Distributed Ledger Transactions via PVORM
blockchain confidential transactions
2017/4/17
In this paper we present Solidus, a protocol for confidential transactions on public blockchains, such as those required for asset transfers with on-chain settlement. Solidus operates in a framework b...
Bitcoin as a Transaction Ledger: A Composable Treatment
Transaction Ledger Composable Treatment
2017/2/23
In this work we put forth a universally composable treatment of the Bitcoin protocol. We specify the goal that Bitcoin aims to achieve as a ledger shared-functionality, aka global setup, in the (G)UC ...
Scripting smart contracts for distributed ledger technology
electronic commerce and payment blockchain scripting language
2016/12/24
We give an overview of the scripting languages used in existing cryptocurrencies, and in particular we review in some detail the scripting languages of Bitcoin, Nxt and Ethereum, in the context of a h...
Fair and Robust Multi-Party Computation using a Global Transaction Ledger

Influence of Shear Rigidity of Main and Flooring Ledger Frames on the Strength of Simple Prefabricated Scaffolds
Shear Rigidity Main Flooring Ledger Frames Strength Simple Prefabricated Scaffolds
2013/9/30
The presumption method was established to examine the compressive strength of one main frame in order to evaluate the strength of standard prefabricated scaffolds, which in turn is determined by the d...
