Pangea Jurisdiction and Pangea Arbitration Token (PAT)
Pangea Jurisdiction and Pangea Arbitration Token (PAT) The Internet of Sovereignty Susanne Tarkowski Tempelhof, Eliott Teissonniere James Fennell Tempelhof and Dana Edwards Bitnation, Planet Earth, April 2017 Pangea Jurisdiction and Pangea Arbitration Token (PAT) The Internet of Sovereignty Susanne Tarkowski Tempelhof, Eliott Teissonniere, James Fennell Tempelhof and Dana Edwards Bitnation, Planet Earth, April 2017 <abstract_ The Pangea software is a Decentralized Opt-In Jurisdiction where Citizens can conduct peer- to-peer arbitration and create Nations. Pangea uses the Panthalassa mesh, which is built using Secure Scuttlebutt (SSB) and Interplanetary File System (IPFS) protocols. This enables Pangea to be highly resilient and secure, conferring resistance to emergent threats such as high- performance quantum cryptography. Pangea is blockchain agnostic but uses the Ethereum blockchain for the time being. In the future, other chains such as Bitcoin, EOS and Tezos can be integrated with Pangea. The Pangea Arbitration Token (PAT) is an ERC20 compatible in-app token for the Pangea Jurisdiction. The PAT token rewards good reputation and is issued on Pangea when Citizens accumulate non-tradable reputation tokens through creating a contract, successfully completing a contract or resolving a dispute attached to a contract. PAT is an algorithmic reputation token, an arbitration currency based on performance rather than purchasing power, popularity or attention. The distribution mechanism for PAT tokens on Pangea is an autonomous agent, Lucy, which will initially launch on Ethereum as a smart contract. This mechanism is blockchain agnostic and can be ported to any viable smart contract platform. An oracle created by Bitnation will help to facilitate this (semi-) autonomous distribution mechanism in a decentralized and secure fashion. -
Peer-To-Peer Software and Use of NRC Computers to Process SUNSI Frequently Asked Questions
Peer-to-Peer Software and Use of NRC Computers to Process SUNSI Frequently Asked Questions 1. What is peer-to-peer software? Peer-to-peer, or P2P, file-sharing systems provide users with the ability to share files on their computers with other people through the Internet. The most popular P2P software is free and is used to share music, movies, and games, and for Instant Messaging. 2. Why is P2P a problem? P2P software provides the capability for users to access files on other users’ computers beyond those intended for sharing (i.e., music). For example, if you have P2P software on your computer and you also do your own tax preparation on your computer and store a copy of the tax return on your hard drive, other people anywhere in the world may be able to access the files containing your tax return. 3. Have sensitive government files been obtained through the use of P2P? Yes. There are documented incidents where P2P software was used to obtain sensitive government information when peer-to-peer software was installed on a government or home computer. 4. Is someone obtaining sensitive information the only threat? No. P2P can also make it easier for computer viruses and other malicious software to be installed on your computer without your knowledge. 5. Have other Federal agencies adopted similar policies? Yes, other Federal agencies have adopted similar policies. The Office of Management and Budget wrote the requirements for government-wide adoption in 2004. Additionally, due to the increased awareness of the P2P threat that has arisen since 2004, DOT, DHS, DOE, DOD, and other agencies have issued specific P2P policies. -

Technology Stack for Decentralized Mobile Services Matouš Skála Technology Stack for Decentralized Mobile Services by Matouš Skála to obtain the degree of Master of Science at the Delft University of Technology, to be defended publicly on Monday August 31, 2020 at 3:00 PM. Student number: 4893964 Project duration: November 15, 2019 – August 31, 2020 Thesis committee: Dr.ir. J.A. Pouwelse, TU Delft, supervisor Dr. J.S. Rellermeyer, TU Delft Dr. N. Yorke-Smith, TU Delft An electronic version of this thesis is available at http://repository.tudelft.nl/. Preface When I was choosing my thesis topic, I originally came up with an idea of designing a decen- tralized social network. After realizing how ambitious that goal was, I later decided to focus on more fundamental issues first and create a library that would allow for building any de- centralized applications, running purely on an overlay network consisting of smartphones. Rather than reinventing the wheel, I took inspiration from an existing networking library de- veloped at TU Delft over the last decade and created its wire-compatible implementation in Kotlin. Interestingly, in the end, I have even implemented a trivial social network to demon- strate the usage of the library, returning back to the original idea. I would like to thank my supervisor Johan Pouwelse for an endless stream of fresh ideas and valuable feedback, and to PhD students of the Delft Blockchain Lab for numerous coffee meetings and for serving me as a walking documentation of the existing codebase.

P2P-Hate-Report.Pdf
I’m in a community called Scuttlebutt which uses Peer-to-Peer technology. This is a type of technology that works radically differently from the internet as we know it now and offers a powerful vision for a resilient and sustainable future for technology and social movements. One evening, a friend who is a developer on Scuttlebutt and also has marginalized identities like myself messaged me and a small group of others with great concern writing: “Ok - so we have nazis already using scuttlebutt. When the NZ shootings happened I had a dream that in the news it was announced that they had been using an enclave of scuttlebutt to organise and radicalise. It seems inevitable that this will happen…” It continued a long conversation about the risks created by these radical technologies. My friend was genuinely afraid. So was I. And I still am. Like so many others, he had put a ton of work into cultivating both the community and the technology. He was scared both that the product of so many people’s love would become a central aid in white-supremacist organizing and that the community wasn’t ready to deal with the fall out of such a “nightmarish vision.” In most Peer-to-Peer communities it is impossible to surveill them or know how many people are using them because they are secure and often private by design. The only way to even catch a glimpse of how many white supremacists are using them is when they post on leaked forums or public websites. Otherwise, unless their conversations are infiltrated, we can only see the tips of the iceberg of the violence (or good!) facilitated by these technologies.
