This document provides an overview of blockchain technology and Concordium. It discusses how Concordium uses blockchain technology to build a computer network with strong guarantees around trust and security. The document explains key concepts like nodes, consensus mechanisms, smart contracts and different layers of a blockchain system. It also compares blockchains to early computers and discusses how killer apps took advantage of the strengths of new technologies while their weaknesses diminished over time.
An introduction to Blockchain (for nontechnical people)Miguel Neumann
Introduction to basic concepts of blockchain technologies oriented to non-technical audience, explaining in simple terms the capabilities and potential applications of the technology, created by Miguel Neumann for the launch of the Swisscom sponsored Blockchain Meetup in Zurich, for DXMarkets.
Cryptocurrency wallets allow users to transact crypto assets on
the blockchain. Blockchain ensures ownership of the transferred
assets once they are hosted in a wallet.

Easier way to understand the Smart Contract Technology. A simplest explanation of Smart Contract. The technology behind the Blockchain, which is making the Blockchain enthusiast crazy. It is the same technology which has made it possible to implement Blockchain for almost anything.
1. How the Royal Bank of Scotland is approaching research and innovation
2. What we have looked at in the distributed ledger space
3. Example: Building a digital wallet on the Hyperledger Fabric
4. What we've learnt about Hyperledger and other DLs
5. The challenges we face as a bank and as blockchain developers
6. Thoughts for the future
Smart Contracts are a central component to next-generation blockchain platforms. Blockchain technology is much broader than just bitcoin. The sustained levels of robust security achieved by public cryptocurrencies have demonstrated to the world that this new wave of blockchain technologies can provide efficiencies and intangible technological benefits very similar to what the internet has done.
Blockchains are a very powerful technology, capable of going much further than only "simple" financial transaction; a technology capable of performing complex operations, capable of understanding much more than just how many bitcoins one currently has in his digital wallet.
This is where the idea of Smart Contracts come in. Smart Contracts are in the process of becoming a cornerstone for enterprise blockchain applications and will likely become one of the pillars of blockchain technology.
In this presentation, we will explore what a smart contract is, how it works, and how it is being used.
Basics you need to know about Solidity and how it works. Learn the simple way of building a smart contract in Solidity. Tools that can be used with Solidity.
This presentation given at the Stanford Law School Workshop on Computable Contracts provides an overview smart contracts, that run on a blockchain, and also provides an analytical framework for understanding the use cases for their development.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.

26. Nodes
Can be thousands
Consensus
Mechanism
Memory
“Blocks”
Processor
“virtual machine”
Nodes
Each nodes runs all or part of the code required to make
the system function
Nodes are incentivized to behave honestly, but a
well-designed consensus mechanism enforces the
correct operation of the blockchain computer even if a
significant number of nodes misbehave
27. Consensus
Mechanism
The rounds of voting are
broken into “blocks” which
are then chained together,
hence the term
“blockchain.”
A well-designed consensus
mechanism gives
mathematically provable
guarantees about
trustworthiness of the
computer as a whole.
Consensus
Consensus mechanism aggregates the “votes” from nodes to determine the
correct operation of the blockchain computer.
28. The system provides trust guarantees to
anyone using it (since nothing can be
computed without widespread agreement
of the nodes i.e. the consensus mechanism).
29. A virtual computer that runs on top of a network
of physical computers that provides strong,
auditable, game-theoretic guarantees that the
code it runs will continue to operate as designed.
