Automatic Bitcoin Address Clustering
Jan 04, 2018
The Bitfury Group, the world’s leading full-service Blockchain technology company, and its world-class global development team detail in this white paper a new solution to help reveal relationships between bitcoin addresses that minimizes errors in data and ensures greater accuracy in linking bitcoin addresses for criminal investigations, while also showing bitcoin users ways to protect their privacy.
On Blockchain Auditability
Nov 29, 2016
The Bitfury Group released a white paper today, titled “On Blockchain Auditability,” that explores the key properties of legitimate Blockchains, including auditability, accountability and non-repudiation. The white paper explores how Blockchain technology allows for these properties, including blockchain receipts, blockchain anchoring, and proof of work.
Shared Send Untangling in Bitcoin
Aug 24, 2016
This white paper focuses on the existing tangling techniques of “shared send” transactions and presents an approach to detect usage of mixing schemes. First, we demonstrate that a substantial part of shared send transactions could be untangled. Second, we propose a number of practically useful modifications to this challenge and we present the results of computational experiments on shared send untangling.
Flare: An Approach to Routing in Lightning Network
Jul 07, 2016
This whitepaper is about Flare, a hybrid routing algorithm for payment routing on the Lightning Network. The paper suggests a two-phase algorithm: (1) a proactive update of the node’s routing map, which stores information about network topology, along with (2) reactive collection of information as needed when required by a Lightning Network request. This white paper is the first attempt to describe and preliminarily test an algorithmic solution for future implementation of the Lightning Network on the Bitcoin Blockchain that will allow for transaction processing scalability. The paper is a product of collaboration with co-author Olaoluwa Osuntokun, and the rest of the Lightning Network team.
Digital Assets on Public Blockchains
Mar 15, 2016
The BitFury Group's white paper, “Digital Assets on Public Blockchains,” explores how digital assets can be securely stored and transferred on the bitcoin-secured public Blockchain. A digital asset is a floating claim of a certain service or goods, ensured by the asset issuer, that is governed using computer technologies and the Internet. Throughout the compilation of this white paper, The BitFury Group found that using blockchain infrastructure for digital asset management would allow the global economy to create purely digital assets and manage them entirely online. Our white paper concludes that this allowance opens many new doors to opportunity throughout the world.
Incentive Mechanisms for Securing the Bitcoin Blockchain
Dec 07, 2015
This white paper studies the two major incentive mechanisms which provide for the security and immutability of the Bitcoin blockchain: block rewards and transaction fees. We examine the role such incentives play in providing the resilience of the Bitcoin blockchain to blockchain reorganization and denial of service attacks, and the sources of blockchain security in the context of emerging off-chain payment methods. Machine-to-machine / Internet of Things payments are also examined due to the enabling impact blockchain technology could have in organizing the decentralized economy. Lastly, we present a methodology for estimating the aggregate transaction fees over the Bitcoin network in the medium term based on existing and emerging Bitcoin applications.
