Blockchain-based cryptocurrencies have demonstrated how to securely implement traditionally centralized systems, such as currencies, in a decentralized fashion. However, there have been few measurement studies on the level of decentralization they achieve in practice. We present a measurement study on various decentralization metrics of two of the leading cryptocurrencies with the largest market capitalization and user base, Bitcoin and Ethereum. We investigate the extent of decentralization by measuring the network resources of nodes and the interconnection among them, the protocol requirements affecting the operation of nodes, and the robustness of the two systems against attacks. In particular, we adapted existing internet measurement techniques and used the Falcon Relay Network as a novel measurement tool to obtain our data. We discovered that neither Bitcoin nor Ethereum has strictly better properties than the other. We also provide concrete suggestions for improving both systems.

Abstract. This short note describes a simple approach for aggregating many BLS signatures on a common message, so that verifying the short multi-signature is fast. Moreover, the system supports public key aggregation, where the verification algorithm only uses a short aggregated public key. The original public keys are not needed for verifying the multi-signature. An important property of the construction is that the scheme is secure against a rogue public-key attack without requiring users to prove knowledge of their secret keys (this is sometimes called the plain public-key model). The construction builds upon the work of Bellare and Neven, and the recent work of Maxwell, Poelstra, Seurin, and Wuille.

Tracking a Bitcoin Thief pt. I:
The Philippine Connection and the Truth behind CryptoRush.in
We are BITCOMSEC, please see final pages of this document for more information about us, and how we can help you!
PDF Available Here: http://s000.tinyupload.com/?file_id=00012725220068358517

For the last two years the crypto currency scene had exploded in size as people began learning about and participating in Bitcoin and its alternate currencies. Altcoins as people call them are smaller projects that can be mined and often traded directly for Bitcoin by miners who can not afford to mine Bitcoin directly. With this uprising of alternate currencies came the rise of many Exchanges; sites that provided a platform and medium for supporters, miners and traders of these projects to buy/sell/trade these currencies.
One of these altcoin exchanges was CryptoRush.in; a site dedicated to providing a fast paced medium for users to trade brand new crypto currencies which were traded at exchanges sometimes less than an hour after they were released. Unfortunately CryptoRush suffered a series of break-ins that crushed many members of the community but also provided an opportunity for us at BITCOMSEC to research, analyse evidence and track down the perpetrators. This article details over 7 months of logs, evidence and research that we have looked at to pinpoint exactly what happened at CryptoRush, its owners and who did walk away with all that money...
It is mid-September 2013 when a contractor decides to accept a job request from an employer on Elance.com. Elance is an international freelance job platform which connects businesses with freelance workers through the site as a medium with a staggering 2 million companies and 8 million freelance workers exchanging jobs, and information on a day by day basis. This job seeker turned out to be Jimmy Bluey Amatong - jbluey for short, and this is his tale.
Where it begins:
Shortly after being accepted for the job JBA, as we will call him from now on, got into the world of crypto currency thanks in part to another previous client:

With his quick introduction to mining and crypto currency came the creation of an infamous scam site called xtrapool.com. On December 12th 2013 xtrapool was created as JBA’s foray into the altcoin world; it was setup on 85.25.152.63 (which JBA still uses to host AmtechCebu.com an Amatong family owned business) and began being advertised on December 29th 2013:
