Often, they are technologists who may not be thinking of the intricacies of regulation in the industry. Or, they may be business veterans who are acutely aware of the pitfalls of legal and compliance requirements and need a go-to firm to advise them on the do’s and don’ts currently affecting their intended industry. While innovators are blazing new trails, many areas of law continue to remain unclear and companies must make sensible judgments in achieving compliance. Having a strong understanding of the legal landscape - as well as history of how we got here - is key to building a successful company in the blockchain sector. Reed Smith’s document is an important resource for participants in the blockchain ecosystem, laying out the foundation for regulatory oversight and then diving in to specific use cases and geographies to help guide this industry to success in a regulated environment.

As scrutiny from practitioners and researchers intensifies, various industries and use cases are identified that may benefit from adopting Blockchain. In this context, peer-to-peer (P2P) funding through initial coin offerings (ICOs) is often singled out as one of the most visible and promising use cases. ICOs are novel forms of crowdfunding that collect funds in exchange for so-called Blockchain tokens. These tokens can represent any traditional form of underlying asset and have already been used, among others, to denote shares in a company, user reputations in online systems, deposits of fiat currencies, and balances in cryptocurrency systems. Importantly, ICOs allow for P2P investments without intermediaries. In this chapter, we explain the fundamentals of ICOs, highlight their differences to traditional financing, and analyze their potential impacts on crowdfunding.

  • The Allegheny County Bar in the Eighties Frank C
    The Allegheny County Bar in the Eighties Frank C. McGirk That Iwas admitted to the Bar of Allegheny County in 1880, and am still in the practice of my profession, is most likely the reason Iwas chosen to deliver this address. Iknew the great lawyers of that decade, —many of them intimately, —and frequently tried cases with and against them, and while Ithen knew their peculiarities and abilities, and the many stories then current about them, lapse of time and a failing memory willprevent the repetition of a great many matters of much interest, and jovial happen- ings of those old days. From the earliest days of this County, it has been noted for its great lawyers. Such men as Alexander Ad- dison, James Ross, Hugh Henry Brackenridge, John Woods, Thomas Collins, William Wilkins, Henry Baldwin, James Mountain, Samuel Roberts, Walter Forward, John H. Chap- lin,Neville B. Craig, Charles Shaler, Richard Biddle, John Henry Hopkins, and James Hall, of the early Pittsburgh Bar, and concerning whom, the late Judge Daniel Agnew delivered a most interesting address before the Allegheny County Bar Association on December 1, 1888, made our Bar famous throughout the land and shed great glory on the Pittsburgh lawyer. But the lawyers of the Eighties were just as great. The limits of time allowed me for this address willpermit me to refer only to a small number of those who were fam- ous in the Eighties, and no doubt Imay overlook some whom my brethren at the Bar will think well deserve remem- brance. As Judge Agnew said in his address : "The life of an upright, honorable and learned lawyer is full of instruction.

    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.

  • Initial Coin Offerings: Financing Growth with Cryptocurrency Token
    Initial Coin Offerings: Financing Growth with Cryptocurrency Token Sales Sabrina T. Howell, Marina Niessner, and David Yermack⇤ June 21, 2018 Abstract Initial coin offerings (ICOs) are sales of blockchain-based digital tokens associated with specific platforms or assets. Since 2014 ICOs have emerged as a new financing instrument, with some parallels to IPOs, venture capital, and pre-sale crowdfunding. We examine the relationship between issuer characteristics and measures of success, with a focus on liquidity, using 453 ICOs that collectively raise $5.7 billion. We also employ propriety transaction data in a case study of Filecoin, one of the most successful ICOs. We find that liquidity and trading volume are higher when issuers offer voluntary disclosure, credibly commit to the project, and signal quality. s s ss s ss ss ss s ⇤NYU Stern and NBER; Yale SOM; NYU Stern, ECGI and NBER.

In an ICO, a blockchain-based venture raises capital by selling cryptographically secured digital assets, usually called “tokens.” These ventures often resemble the startups that conventionally finance themselves with angel or venture capital (VC) investment, though there are many scams, jokes, and tokens that have nothing to do with a new product or business.

  • Bypassing Non-Outsourceable Proof-Of-Work Schemes Using Collateralized Smart Contracts
    Bypassing Non-Outsourceable Proof-of-Work Schemes Using Collateralized Smart Contracts Alexander Chepurnoy1;2, Amitabh Saxena1 1 Ergo Platform [email protected], [email protected] 2 IOHK Research [email protected] Abstract. Centralized pools and renting of mining power are considered as sources of possible censorship threats and even 51% attacks for de- centralized cryptocurrencies. Non-outsourceable Proof-of-Work schemes have been proposed to tackle these issues. However, tenets in the folk- lore say that such schemes could potentially be bypassed by using es- crow mechanisms. In this work, we propose a concrete example of such a mechanism which is using collateralized smart contracts. Our approach allows miners to bypass non-outsourceable Proof-of-Work schemes if the underlying blockchain platform supports smart contracts in a sufficiently advanced language. In particular, the language should allow access to the PoW solution. At a high level, our approach requires the miner to lock collateral covering the reward amount and protected by a smart contract that acts as an escrow. The smart contract has logic that allows the pool to collect the collateral as soon as the miner collects any block reward. We propose two variants of the approach depending on when the collat- eral is bound to the block solution. Using this, we show how to bypass previously proposed non-outsourceable Proof-of-Work schemes (with the notable exception for strong non-outsourceable schemes) and show how to build mining pools for such schemes. 1 Introduction Security of Bitcoin and many other cryptocurrencies relies on so called Proof-of- Work (PoW) schemes (also known as scratch-off puzzles), which are mechanisms to reach fast consensus and guarantee immutability of the ledger.
