The Blockchain Community of Practice is a place for Red Hatters to learn about decentralized web technologies, including decentralized ledgers, storage, and many others. This repository is meant so serve as both a means of organizing upcoming talks, as well as storing recordings and presentations of past talks, along with any demos/workshops that accompany them.
Deep-dive on how to use a Linux environment for Blockchain Development via Cartesi
Lead Developer Advocate
Cartesi
Cartesi, The Blockchain OS, is a layer-2 platform for the development and deployment of scalable decentralized applications. Cartesi offers a Linux operating system coupled with a blockchain infrastructure, which allows DApps to be developed in familiar programming languages like Python, c++, SQL and others without the need to write Solidity code.
Cartesi’s core technology relies on its virtual machine that emulates a RISC-V ISA, called the Cartesi Machine. It has been designed to run computationally-intensive decentralized logic off-chain, on a Linux environment. This way, developers can bring their ideas to life in their favorite languages and libraries, without giving up on the solid security guarantees of the blockchain.

From Smart Contracts to Hyperstructures
Let's discuss some basics of Smart Contract development on EVM compatible chains and peak into what the smart people aroudn blockchain applications talk about and how they envision the future.
I'll make the presentation short and then we can have a Q&A and discuss.

Waku: decentralized messaging
Core Contributor
Status
At Status we are building “asshole-resistant” open source infrastructure. Waku is an open source general messaging protocol using peer-to-peer technologies to allow security, privacy and scalability. Let’s talk about how it works and how it is already being used and what future holds.

Few advantages of (e)UTXO & Ergo blockchain
We will explore few advantages of (e)UTXO based blockchains and some drawbacks of it's design when it comes to Smart Contracts. We will take a look at the fundamentals behind crypto and Bitcoin. Then we will learn about Ergo blockchain, which builds on Bitcoin fundamentals and improves on them while sticking to the principles.
During this presentation we will go through:

Web3 Observability with Blocktorch
CEO & Co-Founder
Blocktorch
observability tools for decentralized infrastructure are a missing puzzle piece in web3.
As a result engineering teams build their own observability and monitoring tools in-house and/or use a lot of their time to handle errors, apply manual processes to understand system behaviour, only act reactively on anomalies.
At blocktorch we are building an end-to-end observability platform, providing logs metrics and traces for decentralized applications.

BlockDAGs as the blockchain trillema solver
Technical writer
Red Hat
Me, Michal Maler of Red Hat, would like to invite Dr. Yonatan Sompolinsly, the Kaspa core contributor, to our weekly blockchain call.
Dr. Yonatan Sompolinsky is the founding scientist of DAGlabs. He received his Ph.D. from the Hebrew University of Jerusalem. His research, which was mentioned in the Ethereum whitepaper, focused on the design and analysis of permissionless consensus protocols. He is the co-author of GHOST (2015), SPECTRE (2016), and PHANTOM (2018) protocols. Dr. Sompolinsky is now a Computer Science postdoc at Harvard University, researching transaction ordering incentives and dynamics. He is a founder and contributor to the Kaspa protocol, a new PoW base layer that implements his research work.
BlockDAG - a technology that can go hand-in-hand with blockchain but also acts as a new meta-technology that challenges it. By storing blocks as graphs while being protected by the power of Proof-of-Work, it seeks to overcome the shortcomings that stem from the linear nature of the traditional blockchain. Project Kaspa and their BlockDAG solve the blockchain trilemma issues when delivering high block creation and transaction verification speed while not sacrificing security and decentralization.

History - IBM's Journey, permission vs permissionless, and Hyperledger
Would like to share the history of IBM's journey in blockchain from it's inception to the creation of an Enterprise permissioned blockchain. Discuss what permissioned vs permissionless means. We will also talk about Hyperledger and where it started and it's evolution.

An Introduction to Stacks and Clarity
Stacks is an L1 blockchain tethered to Bitcoin through its unique consensus mechanism, proof of transfer. Bitcoin has traditionally been seen as the OG blockchain, but a bit boring because you can't do much with it. Stacks envisions Bitcoin as a settlement layer, with Stacks serving as the compute layer on top, allowing us to separate the foundational settlement/money layer, while still having the robust functionality provided by smart contracts.
In this talk, we'll go over:

Storedat.io : Web3 storage made easy
Software Developer
Glosseta Foundation
In this presentation I will give an overview and demo of Storedat: Storedat is a GraphQL API built on top of Web3 storage providers like Arweave and Filecoin. Storedat exists to make decentralized storage more accessible to all by abstracting the web3 away from developer experience and letting people read/write data through a single API in a provider agnostic way. No dealing with wallets, signing transactions, managing private keys, paying transaction costs, and so on. Just plug in and Storedat.
