Yonatan Sompolinsky, Aviv Zohar - Bitcoin’s Underlying Incentives
Incentives are crucial for the Bitcoin protocol’s security and effectively drive its daily operation. Miners go to extreme lengths to maximize their revenue and often find creative ways to do so that are sometimes at odds with the protocol. Cryptocurrency protocols should be placed on stronger foundations of incentives. There are many areas left to improve, ranging from the very basics of mining rewards and how they interact with the consensus mechanism, through the rewards in mining pools, and all the way to the transaction fee market itself.


Antony Alappatt - Network Applications Are Interactive
The miniaturization of devices and the prolific interconnectedness of these devices over high-speed wireless networks is completely changing how commerce is conducted. These changes (a.k.a. digital) will profoundly change how enterprises operate. Software is at the heart of this digital world, but the software toolsets and languages were conceived for the host-based era. The issues that already plague software practice (such as high defects, poor software productivity, information vulnerability, poor software project success rates, etc.) will be more profound with such an approach. It is time for software to be made simpler, secure, and reliable.


Jacob Loveless - Cache Me If You Can
The world is more connected than it ever has been before, and with our pocket supercomputers and IoT (Internet of Things) future, the next generation of the web might just be delivered in a peer-to-peer model. It’s a giant problem space, but the necessary tools and technology are here today. We just need to define the problem a little better.


Theo Schlossnagle - Time, but Faster
The first premise was summed up perfectly by the late Douglas Adams in The Hitchhiker’s Guide to the Galaxy: "Time is an illusion. Lunchtime doubly so." The concept of time, when colliding with decoupled networks of computers that run at billions of operations per second, is... well, the truth of the matter is that you simply never really know what time it is. That is why Leslie Lamport’s seminal paper on Lamport timestamps was so important to the industry, but this article is actually about wall-clock time, or a reasonably useful estimation of it.


To those with even a passing interest in the history of the Internet and TCP/IP networking, Van Jacobson will be a familiar name. During his 25 years at Lawrence Berkeley National Laboratory and subsequent leadership positions at Cisco Systems and Packet Design, Jacobson has helped invent and develop some of the key technologies on which the Internet is based. He is most well known for his pioneering contributions to the TCP/IP networking stack, his seminal work on alleviating congestion on the Internet, his leadership in developing the MBone (multicast backbone), and his development of several widely used IP networking tools, such as trace-route, pathchar, and tcpdump.
