This generated significant legal and regulatory developments as U.S. regulators faced numerous novel products attempting to blend the old with the new. Although facing so many novel issues, the regulators’ responses tell a familiar story of the struggle to balance the yin of customer protection with the yang of encouraging financial innovation and competition. Below is a summary of 2017 developments from the SEC, CFTC, OCC, FinCEN and the States. I. Securities and Exchange Commission a. Bitcoin Exchange-Traded Products A number of sponsors of proposed Bitcoin exchange traded products had applications for approval pending before the Securities and Exchange Commission at the beginning of 2017. In March 2017, the SEC rejected a proposal backed by Tyler and Cameron Winklevoss.2 The Bats Exchange proposed a rule amendment which would list the shares of the Winklevoss Bitcoin Trust for trading. -

Blockchain & Distributed Ledger Technologies
Science, Technology Assessment, SEPTEMBER 2019 and Analytics WHY THIS MATTERS Distributed ledger technology (e.g. blockchain) allows users to carry out digital transactions without the need SCIENCE & TECH SPOTLIGHT: for a centralized authority. It could fundamentally change the way government and industry conduct BLOCKCHAIN & DISTRIBUTED business, but questions remain about how to mitigate fraud, money laundering, and excessive energy use. LEDGER TECHNOLOGIES /// THE TECHNOLOGY What is it? Distributed ledger technologies (DLT) like blockchain are a secure way of conducting and recording transfers of digital assets without the need for a central authority. DLT is “distributed” because multiple participants in a computer network (individuals, businesses, etc.), share and synchronize copies of the ledger. New transactions are added in a manner that is cryptographically secured, permanent, and visible to all participants in near real time. Figure 2. How blockchain, a form of distributed ledger technology, acts as a means of payment for cryptocurrencies. Cryptocurrencies like Bitcoin are a digital representation of value and represent the best-known use case for DLT. The regulatory and legal frameworks surrounding cryptocurrencies remain fragmented across Figure 1. Difference between centralized and distributed ledgers. countries, with some implicitly or explicitly banning them, and others allowing them. How does it work? Distributed ledgers do not need a central, trusted authority because as transactions are added, they are verified using what In addition to cryptocurrencies, there are a number of other efforts is known as a consensus protocol. Blockchain, for example, ensures the underway to make use of DLT. For example, Hyperledger Fabric is ledger is valid because each “block” of transactions is cryptographically a permissioned and private blockchain framework created by the linked to the previous block so that any change would alert all other Hyperledger consortium to help develop DLT for a variety of business users. -
Blockchain Law: the Fork Not Taken
Blockchain Law The fork not taken Robert A. Schwinger, New York Law Journal — November 24, 2020 I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I— I took the one less traveled by, And that has made all the difference. — Robert Frost Is the token holder — often the holder of some form of digital currency — always free to choose which branch of the fork to take? A blockchain is often envisioned as a record of a single continuous Background: ‘Two roads diverged in a sequential series of transactions, like the links of the metaphorical chain from which the term “blockchain” derives. But sometimes yellow wood’ the chain turns out to be not so single or continuous. Sometimes situations can arise where a portion of the chain can branch off A blockchain fork occurs when someone seeks to divide a into a new direction from the original chain, while the original chain blockchain into two branches by changing its source code, which also continues to move forward separately. This presents a choice is possible to do because the code is open. For those users who for the current holders of the digital tokens on that blockchain choose to upgrade their software, the software then “rejects about which direction they wish to follow going forward. In the all transactions from older software, effectively creating a new world of blockchain, this scenario is termed a “fork.” branch of the blockchain. However, those users who retain the old software continue to process transactions, meaning that But is the tokenholder—often the holder of some form of digital there is a parallel set of transactions taking place across two currency—always free to choose which branch of the fork to different chains.” See generally N. -

Segwit2x –
SegWit2x – A New Statement The Overwhelming power of SegWit2x In order to safeguard the community from an undesired chain split, the upgrade should be overwhelming, but it’s not enough. It should also ‘appear’ as overwhelming. People, businesses and services needs to be certain about what is going to happen and the risks if they won’t follow. My impression is that still too many speaking english people in the western world think the upgrade will be abandoned before or immediately after block 494784 is mined, thus they are going to simply ignore it. That could lead to unprepared patch up and confusion, while naïve users risk to harm themselves. For this reason and for the sake of the Bitcoin community as a whole, we need to show again, clearly and publicly the extent of the support to SegWit2x. We also need to commit ourselves in a widespread communication campaign. I know this is not a strict technical matter, but it could help a lot avoiding technical issues in the future. What we have to do First, we need a new statement from the original NYA signers and all the business, firms and individuals who joined the cause later. That statement should be slightly different from the original NYA though, and I am explaining why. We all know that what Bitcoin is will be ultimately determined by market forces, comprehensive of all the stakeholders involved: businesses, miners, users, developers, traders, investors, holders etc. Each category has its own weight in the process, and everybody has incentives in following the market. -
MYBTGWALLET SCAM the Dark Side of the Fork
MYBTGWALLET SCAM The dark side of the fork Intro After Bitcoin Cash fork on Aug. 1st, Bitcoin was involved in two other forks between October and November: before the so disputed Segwit2x announced fork, on Oct. 24th a new crypto was launched. Bitcoin Gold was a new greedy chance for Bitcoin owners to earn some free money: importing mnemonic seeds or private keys belonging to a BTC wallet in a BTG one they had the opportunity to redeem their free BTG. This was possible through local BTG clients or through some web services such as MyBTGWallet.com, a website listed directly on BTG official webpage. This particular case turned in a scam that stole an impressive number of Bitcoin from “unexperienced” users. The Scam Site MyBTGWallet scam worked in a very simple way: users imported the mnemonic seed of their BTC wallet on the scam page providing in this way the scammer with the private keys needed to steal the balance of bitcoin still on the wallet and any other cryptocurrencies stored on the same wallet (e.g. Ethereum or Litecoin in case it was a multicurrency wallet). MyBTGWallet page The site used a clever trick to save the mnemonic seed into the cookies of the browser and then siphoned the cookies via a google tracking javascript having this way access to all seeds checked on the website. 2 The numbers The website was used by many bitcoin holders after the fork happened. The scammers progressively moved the stolen funds to other bitcoin addresses. Thanks to open source intelligence activities, we were able to create the clusters of the stolen bitcoin and determine that the number of compromised addresses is almost 4500. -

On the Security of Electroneum Cloud Mining
This Selfie Does Not Exist: On the Security of Electroneum Cloud Mining Alexander Marsalek1, Edona Fasllija2 and Dominik Ziegler3 1Secure Information Technology Center Austria, Vienna, Austria 2Institute for Applied Information Processing and Communications (IAIK), Graz University of Technology, Graz, Austria 3Know-Center GmbH, Graz, Austria Keywords: Electroneum Cloud Mining, Cryptocurrency, Impersonation Attack, Image Manipulation. Abstract: The Electroneum cryptocurrency provides a novel mining experience called “cloud mining”, which enables iOS and Android users to regularly earn cryptocurrency tokens by simply interacting with the Electroneum app. Besides other security countermeasures against automated attacks, Electroneum requires the user to up- load selfies with a predefined gesture or a drawing of a symbol as a prerequisite for the activation of the mining process. In this paper, we show how a malicious user can circumvent all of these security features and thus create and maintain an arbitrary number of fake accounts. Our impersonation attack particularly focuses on creating non-existing selfies by relying on Generative Adversarial Network (GAN) techniques during account initialization. Furthermore, we employ reverse engineering to develop a bot that simulates the genuine Elec- troneum app and is capable of operating an arbitrary number of illegitimate accounts on one Android device, enabling the malicious user to obtain an unfairly large payout. 1 INTRODUCTION Rivet, 2019). Due to these effects, both Google and Apple prohibit cryptocurrency mining apps from their During 2017, the first and most popular cryptocurrency, application stores (Apple, 2019; Google, 2018), limiting Bitcoin, experienced an astonishing 13-fold increase in the accessibility of the average smartphone users to crypto mining. Despite this fact, several projects like value (Corcoran, 2017).
