Week 9: My Top Ten List on Blockchain

Probably you remember that my goal was 4-fold:
– test if WOL for one person is possible
– learn about the basics of blockchain
– find out about blockchain for good
– optional goal: implement a smart contract (at least a tiny one)
.
Nobody will be surprised when I name the book by John Stepper and his site www.workingoutloud.com as my top resources on working out loud. Both resources accompanied me through the last weeks.
.
Also through the course of the last 9 weeks I began to value Twitter as a good source of information.
.
My top ten list below does only contain the blockchain part of my goal. It represents in some way my journey throught the world of blockchain during the last 9 weeks. Though I am publishing this list on mypersonalwolchallenge.com it will also be my first posting on www.blockchainforgoodthings.com. Have a look if you like.
.
The list is ordered in the sequence I worked through these resources.
.
  1. Open HPI Blockchain Course
    This free online course on open.hpi.de provides an excellent overview on the basics and principles of blockchain. Each lesson provides some exercises. At the end of each week is a rated homework. After week 2 there is a final exam and participants with more than 50 % correct answers overall receive a certification.
    > This is a great learning resource.
    .
  2. Hasso Plattner Institute: Study “Blockchain Hype or Innovation”
    The study “Blockchain Hype or Innovation”, a technical report by the Hasso Plattner Institute, covers the technical aspects of Blockchain.  When I read through it I sometimes thought: “this is what I always wanted to know about blockchain”.
    > Definitely a good read.
    .
  3. Blockchain for Dummies
    The book”Blockchain for Dummies” by Manav Gupta is made available for free by IBM. On less than 50 pages it  provides a comprehensive introduction into the topic of blockchain. It presents also a good view on how to do business with blockchain and an overview on blockchain use cases. A ten step guide towards a first blockchain application completes this book.
    > This book is an excellent guide to blockchain business.
    ,
  4. Stanford Graduate School of Business Study on Blockchain for Social Impact
    This study provides a good overview of blockchain  for social impact use cases. Use cases are grouped by application area. Typical use cases for each area are summarized in a short overview. It is interesting to learn about the different aspects of how blockchain can create social impact.
    > If you want to get a good overview about Blockchain for social Impact this is the resource to go to.
    .
  5. Blockchain for Good White Paper
    This paper presents a good overview of  what is thinkable and reflects on the opportunities that blockchain could make possible in the area of blockchain for good. Throughout the paper interesting examples are presented.
    > A good resource related to blockchain for good with many interesting cases.
    .
  6. Master Thesis “Analysis of Use Cases of Blockchain Technology in Legal Transactions”
    This master thesis of U. Gallersdoerfer offers a 360 degree view on blockchain covering business side and technological basis. It develops interesting evaluation methods for  blockchain. While reading this master thesis I began to direct my focus into the direction of taxonomy for blockchain use cases. This thesis gave ground to my thought that it should be possible to evaluate blockchain for good use cases with respect to a taxonomy which specifically covers this type of use cases.
    > I learned a lot about blockchain and methodology from the master thesis.
    .
  7. Thoughts on the taxonomy of blockchains & distributed ledger technologies
    Thoughts on taxonomy contain reasoning about the data diffusion model of Distributed Ledger Technologies (DLT)  because at this point DLT in general separates from blockchain.
    > An interesting read when thinking about Taxonomy.
    .
  8. A Taxonomy of Blockchain-Based Systems for Architecture Design
    This paper analyses some classification factors of blockchain based systems: e.g. decentralization, storage and computation, configuration. The impact of these factors on aspects like cost efficiency, performance and flexibility is evaluated and rated.
    > A good approach to blockchain taxonomy.
    .
  9. Positive Blockchain Database
    I met some of the guys from positive Blockchain Database at a Meetup in Frankfurt held in August 2018 and had interesting conversations with them. This database to my knowledge is by far the biggest collection of references to positive blockchain use cases.
    > Impressive!!
    .
  10. Taxonomy of Blockchain Technologies. Principles of Identification and Classification
    A bottom up approach to finding the building blocks of blockchain. All criteria are grouped in categories and provide a very general tool for evaluation of blockchain.
    > I would be interested to know if you can find a criterion which is missing in this impressive list.
