Architecture of the Hyperledger Blockchain Fabricmustafa sarac
The document summarizes the architecture of Hyperledger Fabric, an implementation of a distributed ledger platform. Key points:
- Hyperledger Fabric uses a modular architecture and allows pluggable consensus protocols, currently implementing PBFT.
- It distinguishes between validating peers that run consensus and non-validating peers.
- Smart contracts called "chaincode" are run on peers and can read/write to the ledger state.
- Transactions are added to the ledger through consensus of validating peers executing the chaincode. Membership is currently static.
Hyperledger Explorer is a user friendly web application for hyperleger.User can query specific blocks and transactions.

Witnessing explosive immense growth over the past few years, we have realized many new emerging blockchains started making a move in competition with Binance Smart Chain commonly known as BSC. Like other DAO projects, Upcomings Chain is a genuine follower of this popular blockchain overcoming the shortcomings of the existing blockchain.
Upcomings Chain is introduced to solidify its position to begin a journey to be the most popular DeFi ecosystem to reach an account of more than $20 billion in terms of assets and become a successful DeFi protocol.
Presenting the utmost benefits right from low transaction fees, exceptional high throughput, and rapid transaction completion times, UPC intends to be a low-cost alternative to other hyped blockchains out there.
The team plans to hire hundreds or thousands of crypto projects and assets in collaboration with this new platform recently deployed on official protocols. By leveraging the complete power of blockchain technology as well as smart contracts, Upcomings DAO developed its own blockchain in the name of UPC to create a safer, transparent, reliable, open to all and decentralized internet platform for empowering the individuals and communities around the space.
This blockchain platform portrays an entire suite of DeFi applications such as prediction markets, exchange, yield farms, staking platforms, an NFT marketplace, Metaverse, and much more.
The native asset for Upcomings Chain called as UPCG coins offers a wide variety of use cases and terms to reduce the high inflation being one of the primary source reward assets for participants in the entire ecosystem.
UPC is a decentralized blockchain platform that supports different DApps and many large-scale applications belonging to GameFi, SocialFi, and the Metaverse domains. Upcomings Chain is a proof-of-authority-based blockchain quite compatible with the network protocols which allows common users and developers to build DApps and feasibly migrate to the core chain.

Lee Barnes - Path to Becoming an Effective Test Automation Engineer.pdfleebarnesutopia
So… you want to become a Test Automation Engineer (or hire and develop one)? While there’s quite a bit of information available about important technical and tool skills to master, there’s not enough discussion around the path to becoming an effective Test Automation Engineer that knows how to add VALUE. In my experience this had led to a proliferation of engineers who are proficient with tools and building frameworks but have skill and knowledge gaps, especially in software testing, that reduce the value they deliver with test automation.
In this talk, Lee will share his lessons learned from over 30 years of working with, and mentoring, hundreds of Test Automation Engineers. Whether you’re looking to get started in test automation or just want to improve your trade, this talk will give you a solid foundation and roadmap for ensuring your test automation efforts continuously add value. This talk is equally valuable for both aspiring Test Automation Engineers and those managing them! All attendees will take away a set of key foundational knowledge and a high-level learning path for leveling up test automation skills and ensuring they add value to their organizations.
From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
LF Energy Webinar: Carbon Data Specifications: Mechanisms to Improve Data Acc...DanBrown980551
This LF Energy webinar took place June 20, 2024. It featured:
-Alex Thornton, LF Energy
-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Keywords: AI, Containeres, Kubernetes, Cloud Native

"Choosing proper type of scaling", Olena SyrotaFwdays
Imagine an IoT processing system that is already quite mature and production-ready and for which client coverage is growing and scaling and performance aspects are life and death questions. The system has Redis, MongoDB, and stream processing based on ksqldb. In this talk, firstly, we will analyze scaling approaches and then select the proper ones for our system.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Introducing Hashi
● Hashi defines a standard for cross-chain
communication based on additive security
● At its core it’s a Hash Oracle Aggregator
● Goal: Distributing trust for bridges over
multiple distinct implementations
● RAIHO (Redundant Array of Hash Oracles)
3. Encode x Gnosis Chain Hackathon 2023
Why Hashi?
● In 2022 more than $2B in assets
were stolen in various token bridge
exploits.
● Rekt.news leaderboard → 4 of the
top 5 are bridges
● No bridge security mechanism is
100% secure
● All bridge designs have trade-offs
4. Encode x Gnosis Chain Hackathon 2023
Design Principles
● Standardization at the lowest level (hash oracle)
● Diversification on the cross-chain communication
protocol implementations (bridges)
○ No bridge implementation is 100% secure
● Security over latency
○ Can be as fast as its slowest oracle
● Redundancy reduces fragility
○ Functions during outages and exploits
7. Encode x Gnosis Chain Hackathon 2023
What to build with Hashi?
● Additional hash oracle adapters:
○ Particularly interested in ZK bridges
(e.g. SuccintLabs, Dendreth, ZKCollective)
● Contracts for validating storage or event proofs, given a hash
● Alternate versions of GiriGiriBashi
○ Alternate aggregation or governance rules
● Build an end-to-end app on top of Hashi (Token, NFT, or Governance bridge)
