Unbundling the Social Media Stack - Could a Decentralized Protocol Bring Real Choice and Control?

Project Liberty's Institute sat down with Wendy Seltzer, an advisor to the Decentralized Social Networking Protocol (DSNP). Wendy was counsel to the World Wide Web Consortium (W3C), and has served on the boards of The Tor Project, Open Source Hardware Association and ICANN. more

2023 Routing Security Summit Starts July 17 - Participate Virtually

Interested in learning more about routing security? How it can affect your connectivity supply chain? What are best practices for enterprises and organizations? What is the role of CSIRTs in securing routing? What are governments doing now, and planning to do in the future around routing security? more

Happy 50th Birthday Ethernet

ome 50 years ago, at the Palo Alto Research Centre of that renowned photocopier company Xerox, a revolutionary approach to local digital networks was born. On the 22nd of May 1973, Bob Metcalf authored a memo that described "X-Wire," a 3Mbps common bus office network system developed at Xerox's Palo Alto Research Center (PARC). more

How to Design a Decentralized Social Media Protocol – Be Ruthless About Technical Requirements and Eager to Build Coalition

Project Liberty's Institute sat down with Dave Clark, an early contributor to the TCP/IP protocols that built and run the Internet, and one of the expert advisors on DSNP, the Decentralized Social Networking Protocol. Dave Clark is Senior Research Scientist at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and Fellow of the National Academy of Engineering and the American Academy of Arts and Sciences. more

50 Years of Ethernet

The idea for Ethernet was born fifty years ago in May 1973 when Robert Metcalf coined the word Ethernet. He had been studying ALOHAnet, developed at the University of Hawaii in 1971 and was the first public demonstration of a wireless packet data network. Metcalf used the work Ethernet as a reference to luminiferous aether, a concept postulated in the 17^th century to explain how light could be transmitted through a vacuum. more

Building a More Secure Routing System: Verisign’s Path to RPKI

At Verisign, we believe that continuous improvements to the safety and security of the global routing system are critical for the reliability of the internet. As such, we've recently embarked on a path to implement Resource Public Key Infrastructure (RPKI) within our technology ecosystem as a step toward building a more secure routing system. In this blog, we share our ongoing journey toward RPKI adoption and the lessons we've learned as an operator of critical internet infrastructure. more

Failed Expectations: A Deep Dive Into the Internet’s 40 Years of Evolution

In a recent workshop, I attended, reflecting on the evolution of the Internet over the past 40 years, one of the takeaways for me is how we've managed to surprise ourselves in both the unanticipated successes we've encountered and in the instances of failure when technology has stubbornly resisted to be deployed despite our confident expectations to the contrary! What have we learned from these lessons about our inability to predict technology outcomes? more

An Economic Perspective on Internet Centrality

The IETF met in November 2022 in London. Among the many sessions that were held in that meeting was a session of the Decentralised Internet Infrastructure Research Group, (DINRG). The research group's ambitions are lofty: DINRG will investigate open research issues in decentralizing infrastructure services such as trust management, identity management, name resolution, resource/asset ownership management, and resource discovery. more

Trust and Insecurity

When I was first advocating home networking at Microsoft, we encountered a problem. The existing systems and applications had implicitly assumed they were inside a safe environment and didn't consider threats from bad actors. Early Windows systems hadn't yet provided file system with access control and other protections though there were some attempts to have separate logins to keep some settings separate. more

Do You Know Someone Who Should Be in the Internet Hall of Fame? Nominations Now Open Until March 24

Do you know someone who deserves recognition for helping build the Internet in their region or country? Or someone who made the Internet more secure through the work they've done? Or someone who made some major technical innovation that made the Internet faster or better? more

Celebrating 35 Years of the DNS Protocol

In 1987, CompuServe introduced GIF images, Steve Wozniak left Apple and IBM introduced the PS/2 personal computer with improved graphics and a 3.5-inch diskette drive. Behind the scenes, one more critical piece of internet infrastructure was quietly taking form to help establish the internet we know today. November of 1987 saw the establishment of the Domain Name System protocol suite as internet standards. more

The Modern Encryption Debate: What’s at Stake?

The debate around encryption has become a hot topic in a world where communications are increasingly becoming digital. The modern encryption debate is a complex and nuanced issue, with many players from different backgrounds trying to influence the conversation. The question of balancing the need for national security with the right to privacy has been a matter of public debate for years. Only recently has the issue been framed in terms of encryption, but the discussion is certainly not new. more

The Short History of the Internet: From ARPANET to the Metaverse

Last Saturday marked the 53rd anniversary of the Internet. While the vast majority of its five billion users have been online for less than a decade, the Internet was taken into use on October 29th, 1969, when two computers connected to the ARPANET exchanged a message. Although the Internet has been around for a while, it remained below most people's radar until the late 1990s when the dot com boom started. more

CIDR in Networking: Improved IP Routing Efficiency

CIDR (Classless Inter-Domain Routing) is a routing system in which network engineers can distribute IP addresses based on the size of their specific network. This is more efficient than the previous system, which assigned IP addresses depending on whether the size of a network fits into one of only three sizes: Class A, Class B, and Class C. more

Monumental Cybersecurity Blunders

Two recent celebrated cybersecurity standards history events brought together sets of people who were intimately involved with some of the most significant network security standards work ever undertaken. These included the X.509 digital certificate standards at ITU X.509 Day, and the Secure Digital Network System (SDNS) standards at the NSA Cryptologic History Symposium 2022. more
