Blockchain Technology: What Is It Good for?:
Industry’s dreams and fears for this new technology

Business executives, government leaders, investors, and researchers frequently ask the following three questions: (1) What exactly is blockchain technology? (2) What capabilities does it provide? (3) What are good applications? Here we answer these questions thoroughly, provide a holistic overview of blockchain technology that separates hype from reality, and propose a useful lexicon for discussing the specifics of blockchain technology in the future.

Net Neutrality: Unexpected Solution to Blockchain Scaling:
Cloud-delivery networks could dramatically improve blockchains’ scalability, but clouds must be provably neutral first.

Provably neutral clouds are undoubtedly a viable solution to blockchain scaling. By optimizing the transport layer, not only can the throughput be fundamentally scaled up, but the latency could be dramatically reduced. Indeed, the latency distribution in today’s data centers is already biased toward microsecond timescales for most of the flows, with millisecond timescales residing only at the tail of the distribution. There is no reason why a BDN point of presence would not be able to achieve a similar performance. Adding dedicated optical infrastructure among such BDN points of presence would further alleviate throughput and reduce latency, creating the backbone of an advanced BDN.

A Hitchhiker’s Guide to the Blockchain Universe:
Blockchain remains a mystery, despite its growing acceptance.

It is difficult these days to avoid hearing about blockchain. Despite the significant potential of blockchain, it is also difficult to find a consistent description of what it really is. This article looks at the basics of blockchain: the individual components, how those components fit together, and what changes might be made to solve some of the problems with blockchain technology.
