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
simulation cryptocurrencies DAG
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
public ledgers formal verification proverif
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 ...
Fair and Robust Multi-Party Computation using a Global Transaction Ledger

2015/12/29
Classical results on secure multi-party computation (MPC) imply that fully secure computation,
including fairness (either all parties get output or none) and robustness (output delivery is
