Blockchain: The Information Technology of the FutureMelanie Swan
The blockchain concept may be one of the most transformative ideas to impact the world since the Internet. Cryptocurrencies like bitcoin are merely one application of the blockchain concept. The blockchain is a public transaction ledger built in a decentralized network structure based on cryptographic principles so that any kind of trading, buying and selling of assets does not need to go through a centralized intermediary. Any kind of asset may be encoded into the blockchain and transacted, validated, or preserved in a much more efficient manner than at present including ideas, health data, financial assets, automobiles, and government documents. Venture Capitalists are calling the blockchain the next big investment wave.
Decentralized finance is a distributed financial system where there is no centralized governing body. Decentralized finance or DeFi applications utilize peer-to-peer finance networks. These networks are powered by decentralized and distributed platforms. The DeFi application ecosystem is vast and it includes various types of apps such as wallets, lending platforms, infrastructure development suits etc.
As there are many DeFi applications on the market, finding the top applications can be a difficult process. Here, we will discuss the top 5 DeFi applications – AAVE, Compound, MakerDAO, Synthetix, and MetaMask.
These are some of the widely utilized applications on the market. If you want to learn more about decentralized finance applications, then we have you covered. 101 blockchains feature a blockchain course that focuses on decentralized finance and will help you understand the working mechanism of this new financial structure.

An introductory presentation discussing the basics of technology behind blockchain, cryptocurrency mining, and an attempt to value a cryptocurrency. Further discussion on altcoins, and a preview on ICOs.
Innovation in Byzantine consensus protocols is helping decentralized networks scale up and become highly performant, possibly faster than centralized networks. Investment growth in Bitcoin and FinTech startups, and enterprise blockchain applications in development in multiple sectors
Stablecoins have emerged as an alternative digital payment system offering the best of both traditional and modern digitized economies. In this deck, Shaan, our blockchain SME, will discuss how fiat-backed stable coins are well-equipped to help users transition seamlessly from a solely fiat-driven economy to a more modern and stable global economy.
Consensus algorithms are an extremely crucial part of blockchain technology. Proof of Work is a type of consensus mechanism where users use their computational devices to solve complex mathematical problems in order to verify and add blocks to the ledger system. On the other hand, in Proof of Stake users will need to stake their coins in order to participate in the verification process.
The difference between the two types of consensus protocol lies within the working mechanism of these two processes. Verification mechanism, incentive policy, vulnerability, motivation, requirement, and scalability are some of the areas where these two differ.
To help you better understand the differences between these two consensus protocols, 101 Blockchain offer an array of lucrative blockchain courses. These courses will help you comprehend the working principles of these two algorithms.

Tokenization on Blockchain is a steady trend. It seems that everything is being tokenized on Blockchain from paintings, diamonds and company stocks to real estate. Thus, we took an asset, tokenized it and created its digital representation that lives on Blockchain. Blockchain guarantees that the ownership information is immutable.
Unfortunately, some problems need to be solved before we can successfully tokenize real-world assets on Blockchain. Main problem stems from the fact that so far, no country has a solid regulation for cryptocurrency. For example, what happens if a company that handles tokenization sells the property? They have no legal rights on the property and thus are not protected by the law. Another problem is that this system brings us back some sort of centralization. The whole idea of Blockchain and especially smart contracts is to create a trustless environment.
Tokenization is a method that converts a digital value into a digital token. Tokenization can be used as a method that converts rights to an asset into a digital token.
The tokenization system can be implemented local to the data that is tokenized or in a centralized model. We will discuss tokenization implementations that can provide scalability across hybrid cloud models. This session will position different data protection techniques, use cases for blockchain, and protecting blockchain.
Non-fungible tokens are a new type of digital token where every token is different and hold unique characteristics. Anything from games to painting and even memes can be an NFT. Thus, it helps to tokenize any type of asset holding any type of intrinsic value.
Due to the 6 key characteristics of NFTs, these tokens have a higher value. These are – Indivisibility, Ownership, Uniqueness, Rarity, Transparency, and Interoperability. Without any of the attributes, a token can’t become an NFT. These tokens also heavily depend on Ethereum token standards. If you want to know more about these tokens, then it’s best to enroll in our specialized course geared solely towards non-fungible tokens.
We at 101 Blockchains, are here to help you understand the concept behind NFTs and help you learn how these are getting so much popular.

Introducing new Proof-of-Stake based networks - Why your network participatio...Michael Ng
This is the slide deck presented by StakeWith.Us for the monthly dappers meetup in Singapore.
Synopsis:
Proof of Work networks are inherently more secure due to high compute cost required for DDoS attacks. However, these networks face scalability bottlenecks as it takes a long time to determine consensus on chain finality - it is very important to ensure that transactions on the blockchain are irreversible, which is why exchanges imposes block confirmations on deposits!
Such bottleneck proves to be a bane in accelerating blockchain adoption, especially in this day and age where payment confirmation takes less than 5 seconds with the click of a button. In order for a blockchain network to be able to serve the needs of the global market, transactions need to be finalized in a much quicker manner.
Multiple Proof of Stake based networks have launched to date. It has proved to be the optimal solution to scalability bottlenecks as these networks prioritize fast finality with limited security and liveness tradeoffs.
Come join us to learn more about various Proof of Stake based networks, why we think they are built for adoption and how you can play your part to show your support by bootstrapping these networks!
This presentation by Isabelle Corbett, Senior Counsel & Director of Regulatory Affairs, R3, was made during the discussion “Blockchain and Competition” held at the 129th meeting of the OECD Competition Committee on 8 June 2018.

GBA – Episode 1 “Enterprise Blockchain Adoption” – Cost of doing blockchainZeeve
Our series on Enterprise Blockchain Adoption is an attempt to lay the groundwork for answering some of the common questions about cost implications. Our speaker will address the concerns that arise at the institutional level when deciding on blockchain adoption challenges. Often misguided information about blockchain adoption costs becomes a reason for driving resistance among business leaders to embrace blockchain technology with open arms. Hence, our speaker will try to put a detailed analysis of the factors that impact the blockchain deployment costs for enterprises.
"Towards True Decentralization: A Blockchain Consensus Protocol Based on Game...eraser Juan José Calderón
"Towards True Decentralization: A Blockchain Consensus Protocol Based on Game Theory and Randomness" de Naif Alzahrani and Nirupama Bulusu. Portland State University, Portland
Abstract.
One of the fundamental characteristics of blockchain technology is the consensus protocol. Most of the current consensus protocols are PoW (Proof of Work) based, or fixed-validators based. Nevertheless, PoW requires massive computational effort, which results in high energy and computing resources consumption. Alternatively, fixedvalidators protocols rely on fixed, static validators responsible for validating all newly proposed blocks, which opens the door for adversaries to launch several attacks on these validators such as DDoS and eclipse attacks. In this paper, we propose a truly decentralized consensus protocol that does not require PoW and randomly employs a different set of different size of validators on each block's proposal. Additionally, our protocol utilizes a game theoretical model to enforce the honest validators' behavior by rewarding honest validators and penalizing dishonest ones. We have analyzed our protocol and shown that it mitigates various attacks that current protocols suffer from.

Dot staking refers to the process of locking up or holding onto the cryptocurrency DOT (Polkadot) in a blockchain network in order to participate in network activities and earn rewards.
When you stake DOT, you contribute to the security and functionality of the Polkadot network. In return, you may receive incentives in the form of additional DOT tokens or other rewards. Staking DOT is a way for individuals to support the network while also potentially generating passive income through staking rewards. It's a fundamental concept in many blockchain ecosystems, promoting network decentralization and consensus.
A small talk given at the Coinscrum meetup on Monday 8th December in London. Explores the notion of a decentralised software-as-a-service, and points that the lack of a legal service-provider leaves only the users and the software. Software is necessarily allegal (i.e. not pertaining to the concept of legal) and thus users themselves must be policed.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
DevOps and Testing slides at DASA ConnectKari Kakkonen
My and Rik Marselis slides at 30.5.2024 DASA Connect conference. We discuss about what is testing, then what is agile testing and finally what is Testing in DevOps. Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
In his public lecture, Christian Timmerer provides insights into the fascinating history of video streaming, starting from its humble beginnings before YouTube to the groundbreaking technologies that now dominate platforms like Netflix and ORF ON. Timmerer also presents provocative contributions of his own that have significantly influenced the industry. He concludes by looking at future challenges and invites the audience to join in a discussion.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

3. What does it provide?
Pooled security
all constituent chains of our community guaranteed
Trust-free transactions
constituent chains can send transactions to each other
4. How does it work?
Relay-chain
the top-level which coordinates consensus and
transaction delivery between constituents
Parachains
constituent chains which gather and process
transactions
5. Basics of the Relay-chain
No functionality
no external transactions, no smart contracts
Fees may be levied
fees paid according to decision of stakeholders
6. Governance of the Relay-chain
TBD
no big decisions made yet, but likely to take much from
present political structures; bi-cameral, multi-role
governance
Stakeholders hold final say
referendum mechanism built-in
7. Polkadot’s Relay-chain ensures that
transactions between the constituent
parachains get delivered and that
they are all operating correctly.
Parachains can take any form of
globally-coherent consensus system;
potentially even another relay-chain.
Enterprise-friendly encrypted, private,
proof-of-authority chains are
supported.
Bridges can exist to ferry transactions
between the relay chain and existing,
independent chains like Ethereum.
Extensible, Scalable
and Flexible
8. Who maintains it?
Validators/nominators
verify and finalise parachain candidates into blocks
Collators
gather parachain transactions into PoV candidates
Fishermen
monitor the network for misbehaviour
9. Polkadot’s mechanics work by
incentivising three kinds of activity.
Collators work independently on each
parachain collecting and executing
transactions. They provide blocks of
transactions to validators.
Validators route transactions between
parachains. They take turns vetting
blocks supplied by collators and finally
sign off to commit one to finality.
Fishermen receive a reward for
reporting misbehaving validators.
Validators, Collators
and Fishermen
10. Why do they bother?
Validators/nominators
rewarded via staking-token expansion
Collators
parachain-specific transaction fees
Fishermen
gifted proportion of the bond of identified culprit
11. Forming Consensus
Relay-chain Proof-of-stake
guarantees shared canonicality of parachains
Structured state-machine
not yet finalised; PBFT-derivative likely
Parallel validation groups
validators partitioned to allow scaling
12. Validators & Nominators
Approval voting
all nominate acceptable validators, minimum reward
Constraint optimiser
provides configuration of validators/nominators for
maximum lowest-bonded, minimum total inflation
Adaptive rewards
rewards alter to target % of capital bonded
14. Relaying Transactions
Peer-to-peer
validators & collators self-organise to arrange delivery of
data
Tries & proofs
tries used to encode ingress/egress queues, allowing
compact proofs of misbehaviour
15. Ensuring Availability
Validators
consensus includes giving availability guarantees
Proof-of-Collator
recent collators can challenge data availability
Mild punishment
validators given slight reward reductions on complaints
16. Ensuring Fairness
important that collator set contains some good guys
Golden ticket
randomly selected address
Mild reward
for validators backing blocks whose collator’s address is
close to ticket
17. Open parachains can be tightly integrated
into Polkadot, using Polkadot’s validators to
ensure their correct operation. They are the
easiest and cheapest form of integration.
Closed parachains can be weakly integrated
into Polkadot, giving them the freedom to
manage validation internally e.g. using a set
of recognised authorities.
Bridged chains can be integrated into
Polkadot too. Bridges add complexity and
cost to integration, but allow the chain to
exercise its own means of consensus.
Polkadot network
Internal/consortium parachain
Authorities manage
parachain validation, access
controls &c.
