Blockchain Application Design and Development, and the Case of Programmable M...Ingo Weber
Slides from my CLOSER 2021 keynote ( https://www.insticc.org/node/TechnicalProgram/closer/2021/presentationDetails/1390 )
Blockchain has emerged as a decentralized platform for managing digital assets and executing 'smart contracts', i.e., user-defined code. While blockchain's suitability for a given use case should always be scrutinized, it does have the potential to disrupt many of the connection points between individuals, companies, and government entities. In this keynote talk, I will provide an overview of what architects and developers need to know in order to build blockchain-based applications, and how it relates to the cloud and software services. Among others, I will cover blockchain-as-a-service concepts, as well as architectural concerns and model-driven engineering for blockchain applications, the latter also in relation to collaborative business processes. To highlight some of the challenges, I will discuss insights from a project on "programmable money", i.e., blockchain-based money for conditional payments where the money itself checks whether it can be spent in a certain way at the point of payment. Finally, I will touch on insights into current adoption of blockchain.

Builder.ai Founder Sachin Dev Duggal's Strategic Approach to Create an Innova...Ramesh Iyer
In today's fast-changing business world, Companies that adapt and embrace new ideas often need help to keep up with the competition. However, fostering a culture of innovation takes much work. It takes vision, leadership and willingness to take risks in the right proportion. Sachin Dev Duggal, co-founder of Builder.ai, has perfected the art of this balance, creating a company culture where creativity and growth are nurtured at each stage.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

In this chapter we will cover the
theory of blockchain technology, and
its technical foundations.

4. Introducing distributed
computing
• A distributed system is a computing paradigm whereby
two or more nodes work with one another, in a
coordinated fashion, to achieve a common outcome.
• A distributed system is modeled in such a way that end
users see it as a single logical platform.
• Examples include clusters and clouds.

6. 6
CAP theorem
This states that a distributed system cannot
have all three of the desired
properties simultaneously; that is:
• Consistency
• Availability
• Partition tolerance
7. 7
Types of faults in
distributed systems
Fail-stop faults (crash faults)
• Where components crash or cease to operate
• Simpler to deal with
Byzantine faults
• Where components are potentially untrustworthy
or malicious
• Difficult to deal with
8. 8
Defining ‘Blockchain’
Layman's definition: Blockchain is an ever-growing, secure,
shared recordkeeping system in which each user of the data
holds a copy of the records, which can only be updated if all
parties involved in a transaction agree to update.
Technical definition: Blockchain is a peer-to-peer distributed
ledger that is cryptographically-secure, append-only, immutable
(extremely hard to change), and updateable only via consensus
or agreement among peers.
10. How did blockchain
technology develop?
• 1991 – Secure timestamping of digital
documents.
• 1992 – Hashcash idea to combat junk emails
• 1994 – S/KEY application for Unix login.
• 1997/2002 – Hashcash
• 2008/2009 – Bitcoin (the first blockchain)
• 1950s – Hash functions
• 1970s – Merkle trees - hashes in a tree structure
• 1970s continued – Research in
distributed systems, consensus, state machine
replication
• 1980s – Hash chains for secure logins
• 1990s – e-Cash for e-payments
