Blockchain is a decentralized ledger or list of all transactions across a peer-to-peer network. There are two types of blockchains: public blockchains where anyone can write and read data, and private blockchains where participants are known and trusted groups. Blockchains use a proof-of-work system to verify transactions and add them to the chain in blocks. Smart contracts allow rules and terms of contracts to be automatically verified and executed through software stored on the blockchain, such as insurance policies. One example use is a blood bank blockchain where blood banks and hospitals can register and request blood supplies be visible to all participants.

Blockchain Security and Privacy
Presentation by DHS S&T at the NY Blockchain 360 Conference regarding Blockchain's relevance to the Homeland Security Enterprise. Results of security and privacy research and development over the last 2+ years and next steps.
A technical Introduction to Blockchain.
This document provides an introduction to blockchain credit and distributed ledger technology. It discusses the problems with traditional systems that rely on centralized authorities, and how blockchain solves this through decentralization and immutability. Blockchain achieves this by bundling digital messages into cryptographically-secured blocks that are linked together in a timestamped chain. This allows for the chronicling of transactions in a way that anyone can verify but cannot be altered. The document then discusses applications of blockchain like cryptocurrencies, smart contracts, and blockchain platforms like Hyperledger and R3. It also covers criticisms of blockchain and fundamentals of cryptographic hash functions used in blockchain.

Blockchain and Smart Contracts (Series: Blockchain Basics)
Blockchain is a tool. Samson Williams likens blockchain to a group text message, in which each participant receives a distributed, time-stamped, tamper-resistant (and encrypted) record of data transactions. Each group text has these characteristics. Everyone in the group “sees” the data, and none can change or gainsay any group message. Smart contracts are computer code put on the blockchain (how, exactly?) that establishes self-executing terms and conditions of a transaction. Are smart contracts smart? If certain data comes in and fulfills a pre-set term or condition, then rights and responsibilities are formed, terminated, modified, or shifted among the parties. Ah certainty and transparency, but also ah garbage in and garbage out. Are some contractual terms not amenable to smart contracting? And are smart contracts necessarily contracts? If not, can they still be useful? If a smart contract is a contract, what is the governing document? Is it the words business people and lawyers use, or is it the code that is supposed to reflect the words?

Blockchain
Blockchain is a decentralized digital ledger that records transactions in groups called blocks. Each new block of transactions is cryptographically linked to the previous block, forming a chain. The blockchain is maintained by a network of computers running blockchain software. When a new transaction is initiated, it is broadcast to the network for validation. Once validated, it is grouped into a block and added to the chain in a process called mining, where miners are rewarded. With blockchain, transactions are nearly impossible to hack since the records are distributed across the network.

Blockchain technology
Blockchain is a distributed ledger that maintains a permanent record of transactions in a peer-to-peer network. Each computer in the network maintains a copy of the ledger to prevent a single point of failure. Blockchain consists of blocks of validated transactions that are linked using cryptography. It allows transactions to be recorded and validated without the need for a central authority. Blockchain has applications in finance, healthcare, and other industries by automating processes and removing trust issues through transparency. However, blockchain also faces challenges from its current limitations in scalability and regulation.
Is there a Blockchain Future for Healthcare?
Blockchain is a distributed ledger technology that enables decentralized approaches without intermediaries. It has several potential healthcare applications including medical banking to disintermediate counterparties, distributed electronic health records, inventory management, and new models for collaborative data sharing and crowdsourcing. However, challenges remain around transaction throughput, security, regulatory uncertainty, and developing business models to implement blockchain in healthcare.
How does blockchain work
This document provides an overview of blockchain technology, how it works, and its applications. It defines blockchain as a decentralized digital ledger consisting of blocks that record transactions across networks so past transactions cannot be altered. The document outlines the history of blockchain, how it provides security through hashing and proof-of-work algorithms, and how cryptocurrencies use blockchain to be immune from counterfeiting without central authorities. It then provides an example of how a basic bitcoin transaction occurs between parties on the blockchain network.
Introduction to Blockchain and Smart Contracts
Blockchain & Smart Contracts! This document provides an introduction to blockchain and smart contracts. It discusses what a blockchain is, why many blockchains exist, consensus algorithms like proof of work and proof of stake, public versus private blockchains, smart contracts and how they work, examples of successful smart contracts, potential use cases, and CIT blockchain projects including Catena which provides blockchain as a service and an iRobot proof of concept.
Blockchain for the Enterprise
Blockchain technology is increasingly being considered for applications in business contexts due to its key properties. It is also very much hyped for its potential to transform existing industries and business models. In Part 1, we will introduce the key properties of blockchain, its limitations, the field and the relevance for SAP and enterprises in general. In Part 2, we will focus on one of the prominent suites available today and provide an demonstration of the POC we’ve developed.
Blockchain: Bitcoin and Beyond
A Blockchain is essentially a distributed database of records or public ledger of all transactions or digital events that have been executed and shared among participating entities. Each transaction in the public ledger is verified by consensus of a majority of the participants in the system. And, once entered, information can never be erased. The Blockchain contains a certain and verifiable record pf every single transaction ever made. Bitcoin, the decentralized peer-to-peer digital currency, is the most popular example that uses block chain technology.
The Bitcoin itself is highly controversial but the underlying Block-chain technology has worked flawlessly and is all set to democratize our digital world. The main advantage of Block chain is that it establishes a system of creating a distributed consensus in the digital online world. It is finding applications in both financial (e.g. Nasdaq Private Equity, Insurance) and non-financial worlds (e.g. Decentralized IoT, Decentralized proof of existence of documents) by removing the dependency on a single Trusted entity. This disruptive technology opens the door for developing a democratic open and scalable digital economy from a centralized one.
Log Mining: Beyond Log Analysis
The presentation will describe methods for discovering interesting and actionable patterns in log files for security management without specifically knowing what you are looking for. This approach is different from "classic" log analysis and it allows gaining an insight into insider attacks and other advanced intrusions, which are extremely hard to discover with other methods. Specifically, I will demonstrate how data mining can be used as a source of ideas for designing future log analysis techniques, that will help uncover the coming threats. The important part of the presentation will be the demonstration how the above methods worked in a real-life environment.
Cryptocurrencies
Bitcoin and other distributed virtual currencies are revolutionizing how monetary value is stored and exchanged on the Internet. Key opportunities and risks will be described. The two main objectives of this talk will be to explain the underlying blockchain and cryptology technologies that make them work, and to demonstrate PHP recipes for using the web services that enable payment processing, identity validation, and smart contract execution.

Blockchain and IOT and the GxP Lab Slides
Blockchain, IoT and the GxP lab technology helping compliance?
This webinar discusses how distributed ledger technology like blockchain and IOTA could help enhance compliance in GxP laboratories. It explores how DLT could be used to track devices, materials, and data in a more transparent, trusted and auditable way. Specifically, it presents a vision of an internet-connected "laboratory of the future" where all devices share data using DLT. This could improve integrity, security and access to data while reducing costs. While DLT cannot directly increase compliance, it may help build trust in GxP systems and processes by making components more transparent to regulators.
Blockchain and Security : A Virtuous Circle?
The relation of the two concepts of ‘blockchain’ and ‘security’ - whether blockchain is redefining cybersecurity, what new challenges are, how we build a virtuous circle between blockchain and security
Author : Dr Mark Moir, Oracle Labs
Introduction to Blockchain
Blockchain is a distributed database that maintains a growing list of transaction records organized in blocks. Each block contains a cryptographic hash of the previous block, transaction data, and a timestamp. This creates a permanent, unalterable record of transactions that is distributed across a peer-to-peer network of nodes. Blockchain technology enables a decentralized system of recordkeeping that does not require a central authority and allows digital transactions to be validated and recorded in a transparent yet secure manner. It has applications in finance, healthcare, supply chain management, and more.

It is a distributed database that maintains a continuously growing list of records called blocks, which are linked and secured using cryptographic algorithms. Each block contains a timestamp, a reference to the previous block, and a set of transactions or data.
Blockchain Organiseren
Naar aanleiding van de publicatie van het boek "Blockchain Organiseren", organiseerde Lieve Vereycken (co-inpetto.org) een event met de auteur, Paul Bessems. Met de ondertitel "fundamenten voor een nieuwe sociaaleconomische orde", zorgde ik voor enige kadering vanuit de huidige orde :) Ook daar is men met blockchain en smart contracts aan de slag gegaan en wordt het enorme potentieel aangeboord. De bouwstenen voor een nieuwe orde zijn er, maar betekent dat een noodzakelijke afbraak van het huidige systeem?

Blockchain technology.docx
Blockchain first appeared in 2008 when Satoshi Nakamoto introduced the blockchain structure for bitcoin, the first cryptocurrency. Prior work on blockchain technology dates back to 1991, but it was Nakamoto who improved the structure by using a hash cash-like technique to record timestamps of added blocks without central authorization. Since 2008, blockchain has grown significantly, with the size of the bitcoin blockchain network reaching over 200 gigabytes by 2020 as adoption of the technology has increased. Blockchain allows transactions to be recorded in a decentralized, immutable public ledger.
Blockchain for Auditors
Blockchain is a revolutionary technology for some industries and applications, however it is commonly misunderstand and confused with the cryptocurrency Bitcoin. Blockchain is the underlying technology that makes Bitcoin and other cryptocurrencies possible, but it can be used for much more than cryptocurrencies alone. This presentation explains what Blockchain is, how it works and expounds on the uses of blockchain technology outside of cryptocurrencies in order to equip IT auditors with the knowledge they need to advise their companies on blockchain implementations. Blockchain has several very real uses cases, such as in logistics and financial payments clearing, however there is a lot of misleading or false information out there. The basics between what a public and private blockchain is, how the chain operates, what are miners, what security considerations exist, etc. will be discussed, along with an overview of how to audit this technology.
Understand what Blockchain is
Describe the differences between public and private blockchains
Understand where blockchain can be useful to companies, and where it is unnecessary
What security considerations exist

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

- 3. WHAT IS A LEDGER? There are two types of ledgers : • Centralized • Decentralized or distributed AJINKYA PANDE
- 4. BLOCKCHAIN = DISTRIBUTED LEDGER At a very high level, the block chain is a decentralized ledger, or list, of all transactions across a peer-to-peer network. AJINKYA PANDE
- 5. THERE ARE TWO TYPES OF BLOCKCHAINS Public blockchains : Ledgers can be ‘public’ in two senses 1. Anyone, without permission granted by another authority, can write data. 2. Anyone, without permission granted by another authority, can read data usually, when people talk about public blockchains, they mean anyone-can-write. Private blockchains : It is network where the participants are known and trusted: for example, an industry group, or a group of companies owned by an umbrella company AJINKYA PANDE
- 7. Proof Of Work AJINKYA PANDE
- 8. SMART CONTRACTS It is a piece of software that stores rules for negotiating the terms of a contract, automatically verifies the contract and then executes the agreed terms. Smart contracts can be stored on the blockchain. For e.g. Insurance company AJINKYA PANDE
