10:35 Arxiv.org CSLockcoin: a secure and privacy-preserving mix service for bitcoin anonymity. (arXiv:1811.04349v1 [cs.CR])

We propose Lockcoin, a secure and privacy-preserving mix service for bitcoin anonymity. We introduce mix servers to provide mix service for user to prevent attackers linking the input address with output address by using blind signature shceme, multisignature scheme. Lockcoin provides anonymity, scalability, bitcoin compatibillity, theft impossibility and accountability. We have proposed a prototype of Lockcoin based on bitcoin test network, experimental results show that our solution is efficient. Lockcoin's source codes are released on github.com/Northeastern-University-Blockchain/Lockcoin.

01:51 TheStar.comHacker’s threat: Pay $857 in Bitcoin or your ‘secret life’ goes public

A nameless, faceless hacker is extorting you. Pay $857 in Bitcoin or videos and screenshots from your “dark secret life” — plus the browsing history on your phone, tablet and computer — will be shared with family, friends and the world.
“You are not my only victim,” the hacker writes. “I usually lock devices and ask for a ransom. But I was struck by the sites of intimate content that you very often visit.”
Several near identical versions of this “phishing” email have been sent out to hundreds of thousands of people in North America over the last few months.
Known by cybersecurity experts as “spray-and-pray” attacks, they are ultimately empty (just don’t click on any attached links) but surprisingly successful threats, say security consultants and police. On Monday, Peel police released a warning to the public about these and other scams.

Late last week an unknown hacker or a group of hackers successfully targeted a cryptocurrency exchange with an aim to steal Bitcoins by compromising the web analytics service it was using.

Криптовалюта Bitcoin, которой на прошлой неделе исполнилось 10 лет, стабилизируется. Хотя ее курс сейчас существенно ниже пиковых значений, близких к 20 000 долларов, зафиксированных в декабре прошлого года, волатильность находится на наименьшем уровне за период с января 2017 года.
Более того, волатильность самой известной криптовалюты стала ниже, чем волатильность акций крупнейших американских компаний, входящих в индекс S&P500.
Уточним, что волатильность S&P500 с конца сентября поднялась до семимесячного максимума. Сказалась обеспокоенность инвесторов, вызванная ростом ставок Федерального резерва и американской политикой протекционизма.

05:56 Arxiv.org CSAn Incentive Analysis of some Bitcoin Fee Design. (arXiv:1811.02351v1 [cs.GT])

In the Bitcoin system, miners are incentivized to join the system and validate transactions through fees paid by the users. A simple "pay your bid" auction has been employed to determine the transaction fees. Recently, Lavi, Sattath and Zohar [LSZ17] proposed an alternative fee design, called the monopolistic price (MP) mechanism, aimed at improving the revenue for the miners. Although MP is not strictly incentive compatible (IC), they studied how close to IC the mechanism is for iid distributions, and conjectured that it is nearly IC asymptotically based on extensive simulations and some analysis. In this paper, we prove that the MP mechanism is nearly incentive compatible for any iid distribution as the number of users grows large. This holds true with respect to other attacks such as splitting bids. We also prove a conjecture in [LSZ17] that MP dominates the RSOP auction in revenue

Почему это имеет значение: у биткоинов есть проблема с энергией, поскольку для обработки транзакций требуется много электричества. Климатологи пытаются определить последствия такого использования энергии, особенно, если популярность этой новой валюты будет расти. Что они сделали: в исследовании предполагается, что использование биткоинов в 2017 году выбросило в атмосферу 69 млн тонн двуокиси углерода, при этом обработав всего 0,033% безналичных транзакций.

Bitcoin has created a new exchange paradigm within which financial transactions can be trusted without an intermediary. This premise of a free decentralized transactional network however requires, in its current implementation, unrestricted access to the ledger for peer-based transaction verification. A number of studies have shown that, in this pseudonymous context, identities can be leaked based on transaction features or off-network information. In this work, we analyze the information revealed by the pattern of transactions in the neighborhood of a given entity transaction. By definition, these features which pertain to an extended network are not directly controllable by the entity, but might enable leakage of information about transacting entities. We define a number of new features relevant to entity characterization on the Bitcoin Blockchain and study their efficacy in practice. We

Currently, the number of Internet of Thing (IoT) devices making up the IoT is more than 11 billion and this number has been continuously increasing. The prevalence of these devices leads to an emerging IoT business model called Device-as-a-service(DaaS), which enables sensor devices to collect data disseminated to all interested devices. The devices sharing data with other devices could receive some financial reward such as Bitcoin. However, side-channel attacks, which aim to exploit some information leaked from the IoT devices during data trade execution, are possible since most of the IoT devices are vulnerable to be hacked or compromised. Thus, it is challenging to securely realize data trading in IoT environment due to the information leakage such as leaking the private key for signing a Bitcoin transaction in Bitcoin system.

In this paper, we present Niji, a new cross-chain protocol that allows parties to perform virtual Bitcoin payment securely on a consortium chain, without any trusted third-party or mediators. Our work focuses on the issue that it is difficult for a consortium chain's token to hold a stable market value, and Niji makes it possible for smart contract services to acquire means of payment in the consortium chain. With the Bitcoin payment channel built on the consortium chain, the process from payment to service provision runs autonomously without any interaction between parties.

16:31 Phys.orgBitcoin better than the dollar?

The name cryptocurrency does not inspire trust. Advanced statistical analysis for the Bitcoin market carried out at the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, however, has not shown any significant differences between its basic statistical parameters and their equivalents for respected financial markets. All indications are that Bitcoin is a better currency than it might seem at first glance.

09:27 Arxiv.org CSThe Looming Threat of China: An Analysis of Chinese Influence on Bitcoin. (arXiv:1810.02466v1 [cs.CR])

As Bitcoin's popularity has grown over the decade since its creation, it has become an increasingly attractive target for adversaries of all kinds. One of the most powerful potential adversaries is the country of China, which has expressed adversarial positions regarding the cryptocurrency and demonstrated powerful capabilities to influence it. In this paper, we explore how China threatens the security, stability, and viability of Bitcoin through its dominant position in the Bitcoin ecosystem, political and economic control over domestic activity, and control over its domestic Internet infrastructure. We explore the relationship between China and Bitcoin, document China's motivation to undermine Bitcoin, and present a case study to demonstrate the strong influence that China has over Bitcoin. Finally, we systematize the class of attacks that China can deploy against Bitcoin to better

04:40 Arxiv.org CSTithonus: A Bitcoin Based Censorship Resilient System. (arXiv:1810.00279v1 [cs.CR])

Providing reliable and surreptitious communications is difficult in the presence of adaptive and resourceful state level censors. In this paper we introduce Tithonus, a framework that builds on the Bitcoin blockchain and network to provide censorship-resistant communication mechanisms. In contrast to previous approaches, we do not rely solely on the slow and expensive blockchain consensus mechanism but instead fully exploit Bitcoin's peer-to-peer gossip protocol. We develop adaptive, fast and cost effective data communication solutions that camouflage client requests into inconspicuous Bitcoin transactions. We propose solutions to securely request and transfer content, with unobservability and censorship resistance, and free, pay-per-access and subscription based payment options. When compared to state-of-the-art Bitcoin writing solutions, Tithonus reduces the cost of transferring data to
