Distributed Securities Depository on blockchain

Using Blockchain Technology and Smart Contracts to Create a Distributed Securities Depository by Eric Wall and Gustaf Malm

“Summarized, this paper aims to:
• Provide an analysis of blockchain technology at its current state of development
• Address the possibilities of leveraging blockchain innovations in the securities market infrastructure
• Address the issues of balancing decentralized blockchain  database structures within the financial industry to conform to regulatory policies
• Outline possible routes of adoption of blockchain technologies in the securities industry while addressing the challenges ahead
• Propose overarching blockchain design choices suitable for a securities depository

Additionally, this paper aims to describe designs for delivery versus payment in different blockchain paradigms.”

BRR – CME Bitcoin Reference Rate Methodology

Summary Description

 The CME CF Bitcoin Reference Rate (“BRR”) is a daily reference rate of the U.S. Dollar price of one bitcoin as of 4:00 p.m. London time. It is representative of the bitcoin trading activity on Constituent Exchanges and is geared towards resilience and replicability.Continue reading

BRTI – CME Bitcoin Real Time Index Methodology

Summary Description

The CME CF Bitcoin Real Time Index (“BRTI”) is a real time index of the U.S. Dollar price of one bitcoin. It is representative of current bids and offers of market participants to buy or sell bitcoin on Constituent Exchanges. It is geared towards timeliness and represents an unbiased estimator of the instantaneous bitcoin price.Continue reading

Lumino whitepaper

Lumino Transaction Compression Protocol (LTCP) 

by Sergio Demian Lerner, Chief Scientist RSK Labs

“…The critical insight behind Lumino compression is delta compression of selected fields, from a previous referenced transaction and the aggregate signing of previous transactions, so previous signatures can be disposed. Delta compression is done by allowing each transaction to refer to a previous transaction from the same owner, which is used as a template. Any field can be overridden, and unmodified fields are copied intact.

zkSNARKs – by Christian Reitwiessner

zkSNARKs in a nutshell

Posted 

“The possibilities of zkSNARKs are impressive, you can verify the correctness of computations without having to execute them and you will not even learn what was executed – just that it was done correctly. Unfortunately, most explanations of zkSNARKs resort to hand-waving at some point and thus they remain something “magical”, suggesting that only the most enlightened actually understand how and why (and if?) they work. The reality is that zkSNARKs can be reduced to four simple techniques and this blog post aims to explain them. Anyone who can understand how the RSA cryptosystem works, should also get a pretty good understanding of currently employed zkSNARKs. Let’s see if it will achieve its goal!Continue reading

Fat Protocols – by Joel Monegro

Fat Protocols

Here’s one way to think about the differences between the Internet and the Blockchain. The previous generation of shared protocols (TCP/IP, HTTP, SMTP, etc.) produced immeasurable amounts of value, but most of it got captured and re-aggregated on top at the applications layer, largely in the form of data (think Google, Facebook and so on).

Mastering Bitcoin – by Andreas M. Antonopoulos’s

Mastering Bitcoin by Andreas M. Antonopoulos

This coming from Antonopolous, the evangelist himself, is defintely worth a closer study.

Book has a rather ‘for newbies’ opening chapters, but warms up into a hands-on sequence that coders may use as a guide to set up as a fully operational Bitcoin node.

The examples are illustrated in Python, C++ and using the command-line of a Unixlike operating system such as Linux or Mac OSX. All code snippets are available in the Github repository (…)

All the code snippets use real values and calculations where possible, so that you can build from example to example and see the same results in any code you write to calculate the same values. For example, the private keys and corresponding public keys and addresses are all real. The sample transactions, blocks and blockchain references have all
been introduced in the actual bitcoin blockchain and are part of the public ledger, so you can review them on any bitcoin system….
