Financial Cryptography

Where the crypto rubber meets the Road of Finance... At some point Hassan Rahimi * wanted to go back, he tells it. Back to Syria , home, to his wife and two sons. They were starving in the devastated land. Rahimi saw himself as a refugee in Germany failed. The family he was not allowed to catch up, he did not get a job. The hopes that had led him to flee in early 2015 were dashed. And so the 35-year-old sat on a summer day 2017 in Berlin-Tegel in a plane to Thessaloniki, Greece. Once there, he entrusted himself to a smuggler. The man should take him to Turkey, the transit country - as if on the way there. A refugee who has been recognized in Germany like Rahimi is not allowed to enter Turkey without further ado. And so the tug Rahimi even before the green border gave an advice: "Sell your papers!" The German documents, refugee card and refugee passport, the AOK card. To deny yourself if border guards suddenly turn up. And to make money. Rahimi did as he was told. He sent the papers by post to his cousin, who lives in Leipzig. And he sold on to a stranger. For 1500 euros. Rahimi was later sent the sum. He was already back in Syria. It's almost as if there is a law of identity documents - they work for the middle road of broad society but fail dismally at the edges. In this case, the desperate, but also the criminal, who are two separate classes merged into one in the fairyland fantasy of the bureaucratic mind. The CDU interior politician Armin Schuster, chairman of the parliamentary control committee in the Bundestag, nevertheless calls sharp sanctions for fraudsters. "Every refugee who participates in a pass trade, has forfeited his right of residence," said Schuster the SPIEGEL. In this case, there must be "an accelerated form of deportation". Yet - the broad swathe o Continue reading >>

The Dark Clouds Of Financial Cryptography

The Dark Clouds Of Financial Cryptography

Ifeel were on the precipice of some delightfully weird and possibly very alarming developments at the intersection of code and money. There is something deep in the rules that is getting rewritten, only we cant quite see how yet. Ive had this feeling before, as a self-described Cypherpunk in the 1990s. We knew or hoped that encryptedcommunication would change global politics,but we didnt quite know how yet. And then Wikileaks happened. As Bruce Sterling wrote at the time , At last at long last the homemade nitroglycerin in the old cypherpunks blast shack has gone off. That was exactly how I felt when thatfirst SIGACT dump hit the net, by then a newly hired editorat the Associated Press. Now Im studying finance, and I cant shake the feelingthat cryptocurrencies and their abstracted cousins, smart contracts and othercomputational financial instruments are another explosion of weirdness waiting to happen. Im hardly alone in this. Lots of technologiststhink the block chain pioneered by bitcoinis going to be consequential. But I think they think this for the wrong reasons. Bitcoin itselfis nevergoingto replace our current system of money transfer and clearing; itsmuch slower than existing payment systems, often more expensive, uses far too much energy, and dont scale well. Rather, bitcoin is just a taste, a hint: it showsthat we can mix computers and money in surprising and consequentialways. And there aremore ominous portents, such as contracts that are actually code and the very first distributed autonomous organizations. But well get to that. What is clear is that we are turning capitalism into code trading systems, economic policy, financial instruments, even money itself and this is going to changea lot of things. The question Ialways come tois this: what do we want ou Continue reading >>

Two Papers Accepted At The Financial Cryptography And Data Security Conference

Two Papers Accepted At The Financial Cryptography And Data Security Conference

Two papers accepted at the Financial Cryptography and Data Security conference Two papers by PhD candidates in the Centre for Cryptocurrency Research and Engineering have been accepted for an upcoming conference. The two papers,authored by Dominik Harz and Alexei Zamyatin, will feature at the Financial Cryptography and Data Security 2018 conference at the end of the month. The conference promotes secure transactions and systems by bringing together researchers and industry applications in an international context. In the past years, the conference has been addressing research related to distributed ledger technologies and cryptocurrencies. As such, the conference hosts several workshops including the Workshop on Bitcoin and Blockchain Research and the Trusted Smart Contracts W orkshop . Authors: Dominik Harz (RA and PhD candidate with IC3RE)and Magnus Boman (KTH and RISE SICS) @ Trusted Smart Contracts Workshop. Open access version . Permission-less blockchains can realise trustless trust, albeit at the cost of limiting the complexity of computation tasks. To explain the implications for scalability, we have implemented a trust model for smart contracts, described as agents in an open multi-agent system. Agent intentions are not necessarily known and autonomous agents have to be able to make decisions under risk. The ramifications of these general conditions for scalability are analysed for Ethereum and then generalised to other current and future platforms. (Short Paper) A Wild Velvet Fork Appears! Inclusive Blockchain Protocol Changes in Practice Authors: Alexei Zamyatin (RA and PhD candidate with IC3RE), William Knottenbelt (Director of IC3RE) in close cooperation with Nicholas Stfiter, Aljosha Judmayer, Philipp Schindler and Edgar Weippl (all SBA Research ) @ Works Continue reading >>

And here is another one made by UCL student Killian Davitt. Wicked, it seems that there is an epidemic of fake volume , and that it comes from China primarily. One way to see which crypto coins are NOT scams is to look at the source code dev statistics, here are some nice stats . Today I have looked at the official website of JesusCoin and their white paper . The same text appears in both. Jeez: what a SHAMEFUL pamphlet FULL of HATE and NONSENSE. Excerpts do not blame me for these we read for example that: Jesus Coin is guaranteed to save all of its owners from hell (except Jews, Muslims, Hindus, Bahai, Buddhists and Sikhs).The website also contains a story of Jonathan, a devote Catholic who raising money toretake Jerusalem and who is at the end able to purchase variousweapons and book plane tickets to the Middle East. I recommend all civilized people to boycott this coin. A large number of UCL academics have yesterday started a large scale strike lasting for manyweeks.These people are sacrificing their salary [UCL will cut their pay down] and there is a strong support for the strike. The strike is organised on the premises that our employer, UCL, are? cutting down their pension contributions or ending guaranteed income schemes and replacing by those which are more like investments, without guaranteed returns. How interesting. I definitely do not support UCL cutting down their contributions, and do I do not think that UCL management are our friends and have good intentions or that they do ever care about people who work here.

Financial Cryptography

Financial Cryptography

Financial cryptography (FC) is the use of cryptography in applications in which financial loss could result from subversion of the message system. Financial cryptography is distinguished from traditional cryptography in that for most of recorded history, cryptography has been used almost entirely for military and diplomatic purposes. Financial cryptography includes the mechanisms and algorithms necessary for the protection of financial transfers, in addition to the creation of new forms of money. Proof of work and various auction protocols fall under the umbrella of Financial Cryptography. Hashcash is being used to limit spam. Financial cryptography has been seen to have a very broad scope of application. Ian Grigg sees financial cryptography in seven layers, being the combination of seven distinct disciplines: cryptography, software engineering , rights, accounting , governance , value , and financial applications. Business failures can often be traced to the absence of one or more of these disciplines, or to poor application of them. This views Financial Cryptography as an appropriately cross-discipline subject. Indeed, inevitably so, given that finance and cryptography are each built upon multiple disciplines. Cryptographers think of the field as originating in the work of Dr David Chaum who invented the blinded signature . This special form of a cryptographic signature permitted a virtual coin to be signed without the signer seeing the actual coin, and permitted a form of digital token money that offered untraceability. This form is sometimes known as Digital currency .

The Uses And Limits Of Financial Cryptography: A Law Professor's Perspective

The Uses And Limits Of Financial Cryptography: A Law Professor's Perspective

Georgia Institute of Technology - Scheller College of Business There is considerable support in the cryptography community for the "Cypherpunk Credo," defined as: "Privacy through technology, not legislation." Much discussion to date has assumed that the U.S. government's opposition to strong cryptography, such as its key escrow proposals, is the primary obstacle to widespread use of cryptography to assure privacy and allow anonymous electronic cash. For purposes of this paper, I assume that strong cryptography is legal and readily available. Even in that event, I claim that strong cryptography will be used to preserve anonymity only in a highly restricted subset of financial transactions. First, I show why anonymous lending will not succeed. Second, I discuss acute difficulties in key management that give individuals and corporations strong incentives to share their keys voluntarily with other parties. Third, I explore problems of market acceptance that would further limit use of technological solutions to assure privacy. In light of these limits on anonymity, even in a world of strong cryptography, we perceive more clearly the limits of a purely technological approach to the protection of privacy. In our present world, where the legal acceptability of strong cryptography is far from assured, the limits of a technological approach are even more significant. Where privacy cannot be assured through technology, we see more clearly the role of legal rules for protecting privacy. Continue reading >>

Financial Cryptography In 7 Layers

Financial Cryptography In 7 Layers

Abstract: Financial Cryptography is substantially complex, requiring skills drawn from diverse and incompatible, or at least, unfriendly, disciplines. Caught between Central Banking and Cryptography, or between accountants and programmers, there is a grave danger that efforts to construct Financial Cryptography systems will simplify or omit critical disciplines. This paper presents a model that seeks to encompass the breadth of Financial Cryptography (at the clear expense of the depth of each area). By placing each discipline into a seven layer model of introductory nature, where the relationship between each adjacent layer is clear, this model should assist project, managerial and requirements people. Whilst this model is presented as efficacious, there are limits to any model. This one does not propose a methodology for design, nor a checklist for protocols. Further, given the young heritage of the model, and of the field itself, it should be taken as a hint of complexity rather than a defining guide. .For a field that is nominally only half a decade old,by some viewpoints, it is apparent fromthe implementation work that has been done thatmany more aspects were involved than envisaged by earlypioneers. Financial Cryptographyappears to be a science, or perhaps an art, that sits atthe intersection of many previously unrelated disciplines: At such a busy juncture of so many distinctive bases ofknowledge, problems are bound to arise. Not onlythe inevitable confusion and wasted resources,but the difficulty in acquiring technical,management and marketing talent that can comfortablywork in the field is an issue. As a preliminary step to the better understanding ofFinancial Cryptography projects,it is often of some interestto structure these disciplines intomodels that aid d Continue reading >>

Financial Cryptography 2018

Im at Financial Crypto 2018 and will try to liveblog some of the sessions in followups to this post. 9 thoughts on Financial Cryptography 2018 The keynote talk was by Yasser Nawaz, executive director of cybersecurity at JP Morgan, and his topic was Blockchain and Cryptography at JPMorgan Chase. Hes in charge of crypto strategy and has to satisfy 60 regulators worldwide, so the blockchain platforms and the apps that run on them have to be compliant. In addition to KYC, he has to scrutinise every transaction. In 2015 they settled on Ethereum as the starting point for trying to code up and speed up the crufty old business logic behind settlement and reconciliation (d day for a trade, three days for a chqeue, two weeks for a syndicated loan). They also plumped for open source. They helped set up the Enterprise Ethereum Alliance with Microsoft and others; their version is called Quorum. Its permissioned, with governance (nodes and activity tied to real-world legal identities), confidentiality (of transactions) and security (in the sense of no trust assumed between nodes). Mostly they stay as close as they can to the public Ethereum codebase. ZSL are on-chain private tokens while Constellation consists of off-chain smart contracts; instead of proof-of-work they have RAFT for leadership election, and Istanbul for Byzantine fault tolerance. The goal is rapid settlement finality. Privacy is added via a Transaction Manager which is conceptually equivalent to a key server plus MTAs plus PGP, and an Enclave that manages keys, optionally using trusted hardware (its a virtual or actual HSM). Applications written for public Ethereum can be dropped on to Quorum and will just run. But you can also create a transaction thats private to n nodes. Each transaction is split between a Quorum Continue reading >>
