Welcome to zk Capital’s Newsletter!
“Significant advancements and innovations in the blockchain space are constantly being achieved by academic researchers. We are committed to helping share and spread this research. In our newsletter, we aim to provide a list of publications that will help guide the community with the latest research in the blockchain space.
Unfortunately, a lot of this research is overlooked due to the massive numbers of papers being generated and the way they are being promoted and published. To tackle this issue, we’ve put together a categorized list of academic papers that can guide our subscribers and keep them up to date.”
Issue #1 (December+January)
This Month in Security:
Summary: This paper reconstructs a Sybil attack exploiting the uncle block distribution policy in queued-based mining pools then proposes mitigation for the attack.
Affiliations: ∗ Imperial College London.
Summary: This paper presents two-factor signatures (2FS), a generalization of a two-out-of-two threshold signature scheme in which one of the parties is a hardware token which can store a high-entropy secret, and the other party is a human who knows a low-entropy password.
Summary: This paper presents the design and implementation of a novel smart contract security technology which is able to protect existing, deployed contracts against re-entrancy attacks in a backward compatible way by performing run-time monitoring of smart contract execution with negligible overhead.
Summary: This paper presents a smart-contract cryptocurrency wallet framework that gives a flexible, usable, and secure way of managing crypto-tokens in a self-sovereign fashion.
Summary: This paper discusses the severity of using blockchains as uncensored decentralized networks for arbitrary data distribution poses a serious regulatory issue by demonstrating a new technique that can be exploited to use the blockchain as a covert bulletin board to secretly store and distribute objectionable content.
Affiliations: ∗ Lancaster University, UK.
Summary: This paper presents a smart contract-based solution that allows end-users to securely interact with smart devices.
Affiliations: ∗ Athens University of Economics and Business.
Summary: This paper proposes a multi-agent plan execution framework based upon Smart contracts on blockchains.
Affiliations: ∗ Ericsson Research, Bangalore, India
This Month in Privacy:
Paper Title: An Empirical Analysis of Monero Cross-Chain Traceability.
Summary: This paper formalizes a new method for tracing Monero transactions, which is based on analyzing currency hard forks.
Summary: This paper proposes a privacy-preserving data management framework that the data owners to specify a fine-grained access policy governing how the captured data are accessed.
Affiliations: ∗ University of Oslo.
Summary: This paper presents a fully decentralized blockchain-based credit network that aims to provide privacy, on-demand routing, and concurrent transactions.
Affiliations: ∗ New Mexico State University.
Paper Title: Wibson: A Decentralized Data Marketplace.
Summary: This paper presents a blockchain-based, decentralized data marketplace for individuals to securely and anonymously sell information in a trusted environment.
Affiliations: ∗ wibson.
Summary: This paper proposes a combination of the virtues of Zerocoin with those of the Confidential Transactions offering fully-featured anonymous transactions between individuals with private amounts.
Authors: Alex Vazquez∗,
Affiliations: ∗ NavCoin.
Summary: This paper proposes a blockchain-based framework to increase the security and privacy of Direct Load Control (DLC). It also proposes a hash-based transaction generation method to reduce the associated overhead for data dissemination.
Summary: This paper presents a proof-of-concept implementation of Secure Private Blockchain-based (SPB) on the Ethereum private network to demonstrates its applicability for energy trading.
This Month in Scalability:
Summary: The paper presents a blockchain that aims to increase the transaction throughput by adopting various optimizations in network transport and storage layers, and to enhance smart contracts with AI algorithm support.
Summary: This paper presents a new permissionless blockchain that achieves scalability in both terms of system throughput and transaction confirmation time, while at the same time, retaining blockchain’s core values of equality and decentralization.
Authors: Ke Liang∗,
Affiliations: ∗ The Fission Project.
Summary: This paper proposes a bidirectional payment channel framework for IoT devices that are unable to maintain a full copy of the bitcoin blockchain in memory.
Affiliations: ∗ Illinois Institute of Technology.
Paper Title: CLoTH: a Simulator for HTLC Payment Networks.
Summary: This paper presents a simulator for Hashed Timelock Contract (HTLC) payment networks such as the Lighting Network (LN).
Summary: This paper proposes a reputation-based secure, high incentive and fast blockchain system via sharding.
This Month in Proofs:
Summary: This paper provides several batching and aggregation techniques for accumulators and vector commitments. These techniques have applications to a new blockchain design where users provide correctness proofs for their transactions and verifiers are not required to store any state.
Affiliations: ∗ Stanford University.
Paper Title: Publicly Verifiable Proofs from Blockchains.
Summary: This paper presents publicly verifiable witness-indistinguishable proof systems from any Σ-protocol, based only on the existence of a very generic blockchain.
This Month in Consensus Protocols:
Paper Title: Blockchain-based P2P File Sharing Incentive.
Summary: This paper proposes a blockchain-based file sharing incentive mechanism leveraged by cryptocurrency and smart contracts.
Authors: Qingzhao Zhang∗, Yijun Leng∗ , and Lei Fan∗,
Affiliations: ∗ Shanghai Jiao Tong University.
Paper Title: Proof-of-Stake Protocols for Privacy-Aware Blockchains.
Summary: This paper studies the feasibility of private PoS protocols while proposing their own version.
Paper Title: Proof-of-Stake Sidechains.
Summary: This paper presents the first formal definition of what a sidechain system is and how assets can be moved between side chains securely. It also provides provide a sidechain construction that is suitable for proof-of-stake (PoS) sidechain systems.
This Month in Interoperability:
Summary: This paper proposes an implementation of an intermediary over a specialized blockchain and presents how this can be used to solve the atomic appends problem even in an asynchronous, client competitive environment, where all the clients may crash.
This Month in Verification:
Summary: This paper describes the formal verification of Smart Contracts offered as part of the Azure Blockchain Content and Samples on github. It also describes a new program verifier VeriSol for Solidity based on a translation to Boogie and leveraging the Boogie verification toolchain.
