This session will demonstrate how to:
• Quickly get and up and running on Algorand
• Use the new Algorand features - ASA, Atomic Transfers and ASC1.
Algorand provides JavaScript, Java, Python and Go SDKs. Learn how to integrate Algorand using the SDKs to build blockchain applications. Community SDKs are available for C# .NET and Rust.
Algorand Standard Asset (ASA) - ASA provides a standardized, Layer-1 mechanism to represent any type of asset on the Algorand blockchain. ASAs can include fungible assets (such as currencies, stablecoins, utility tokens, etc), non-fungible assets (unique assets such as tickets, etc.), restricted fungible assets (such as securities), and restricted non-fungible assets (such as licenses, certifications). Asset issuers, or specified delegates, can optionally have the ability to freeze an account’s ability to transact with their asset and clawback their asset when required.
Atomic Transfers - Atomic Transfers offer a Layer-1 secure way to simultaneously transfer a number of assets among a number of parties. Specifically, many transactions are grouped together and either all transactions are executed or none of them are. This feature can be used for use cases such as matching funding, debt settlement, decentralized exchanges, and complex trades.
Algorand Smart Contract (ASC1) - ASC1s are Layer-1 smart contracts that automatically enforce custom rules and logic, typically around how assets (ASAs or Algos) can be transferred. They are complex economic relationships made up of basic transaction primitives written in a new language called Transaction Execution Approval Language (TEAL). Examples of ASC1s that can be written are escrow accounts, loan payments, limit and stop orders, subscription payments, and collateralized obligations.
Blockchain’s usage is becoming ubiquitous across all sections of the economy including: Medical, Charities, Automotive, Telecom, Food Industry, Voting, Gaming and more. Blockchain’s primary use case is to maintain the integrity of replicated data. Centralized data center hacks seem to be in the news daily as well as identity theft. On the other hand, decentralized data that can easily detect tampering is becoming more and more of a natural solution for data integrity. This is what blockchain technology is all about. For those that are unfamiliar with blockchain, it is a read only, write once immutable ledger which is distributed and globally accessible.
The document discusses Algorand Standard Assets (ASA) which allow users to create native tokens on the Algorand blockchain. It covers how to create, manage, and transfer ASAs, as well as different types of assets like fungible tokens, non-fungible tokens, and restricted assets. It also demonstrates how to query ASA data using tools like the indexer and Algodesk.io. Resources provided include code samples, tutorials, documentation and upcoming developer events.
Algorand is an open-source blockchain network that aims to fulfill the key properties of decentralization, security, and scalability. It uses a pure proof-of-stake approach and verifiable random functions to achieve consensus on new blocks. Transactions have immediate finality due to its consensus protocol, which involves three steps of block proposal, soft voting, and certification. The network architecture supports participation nodes that represent user stakes and relay nodes for communication routing.
This document summarizes the Algorand blockchain protocol. Algorand uses Byzantine Agreement with cryptographic sortition to randomly select committee members to reach consensus in a decentralized way. It assumes an honest majority of money and uses weighted users to prevent Sybil attacks. Algorand achieves high throughput and low latency through its novel BA* consensus protocol which uses committees and achieves consensus in constant time regardless of network size.
This document provides an overview of building applications on the Algorand blockchain. It discusses common developer questions, example applications that have been built on Algorand like Yieldly and Bleumi, and the core layers and tools available for development including Algorand Standard Assets, smart contracts, atomic transfers, and programming tools like PyTeal and Reach. It also includes demos of creating accounts, transactions, smart contracts, and non-fungible tokens.

DevDay: Writing a Secure CorDapp, (almost) Everything You Didn't Know You Nee...R3
This document provides lessons on writing secure smart contracts on Corda by summarizing hacks on Ethereum smart contracts and the security implications of different blockchain designs. It explains that Corda transactions are more secure than Ethereum transactions because they are private between peers and use an accounts-based model instead of UTXO. The document outlines unintuitive security concerns for Corda like checking dependencies and constraints to avoid attacks. It emphasizes that Corda is designed so that transactions always verify the same way to guarantee security and immutability.
The document provides an overview of IBM Blockchain Platform and Hyperledger Fabric. It discusses key concepts like transactions, endorsement policies, smart contracts, and the transaction lifecycle of execute-order-validate on the blockchain network. It also covers developer tools like SDKs, wallets, and how applications can interact with the blockchain network through submitting transactions and listening for events.
We develop an application prototype with Java and Hyperledger Fabric to facilitate people in the company to sell domestic goods to each other using marketplace application. Java and SmartGWT were used to develop UI, part of data were stored in the relational DBMS, while orders and balances were stored on the blockchain, specifically Hyperledger Fabric.
A simple CRUD (no D for the blockchain) cases, you can understand how to use R3 Corda to build a simple "database", record the state by data flow and smart contract.
The document provides an overview of the Hyperledger community update and blockchain frameworks. It summarizes that Hyperledger is an open source collaborative effort hosted by The Linux Foundation to advance blockchain technologies across multiple industries. It then provides details on the various Hyperledger frameworks such as Fabric, Sawtooth, Iroha, Indy, and Burrow. It also summarizes the business blockchain tools under Hyperledger like Composer, Cello, Explorer, and Caliper. The document outlines the leadership and global community engagement efforts around Hyperledger.

Introduction to Blockchain and the Hyperledger ProjectManuel Garcia
Does The Hyperledger Project have the potential to become the engine behind most successful decentralized applications and organizations created in the next 25-50 years? Absolutely!
A much better question is how, and in what new ways, can we:
a) Build decentralized applications, organizations and APIs at 10x the speed at 1/10 the cost.
b) Build situational awareness in the local community.
I believe that the convergence of decentralized applications, decentralized organizations, artificial intelligence and IoT brings upon us the Great Displacement of the 21st century, where the majority of workforce will be left without “conventional” jobs, forced to learn new skills and professions. Why?
Founders of this group believe that the Hyperledger Foundation will be the engine behind decentralization of the world, a massive economic change of the next 25-50 years.
So.... why don't we standardize and democratize the field with and around Hyperledger?
What?
We are a local micro community of those interested in advancing their knowledge of Hyperledger, its use cases and applications.
How?

Trading derivatives on a decentralized system aims for high
availability (HA) and disaster recovery (DR). Both HA and DR can be
met by incorporating a blockchain and a container technology. The
Hyperledger is a blockchain framework aims for a cross-industry open
standard with the freely customizable plugins, smart contract, and the
data payload. Those features exposes us the easy ways to implement our
trading platform on a blockchain. The Docker was brought to handle
each specific Hyperledger chain internally. Also, hovering the whole
Hyperledger nodes with containers reduce our time in building
infrastructure, and much easier to be deployed on the production
environment. This presentation will show how we integrate the
Hyperledger and the Docker container for our derivatives trading
project, and the issues that we are focusing on. Additionally, the
talk partially includes the performance evaluation results under
different configurations.

With the basics of Corda under your belt we will take you to the next level of your Corda distributed application (CorDapp). In this boot camp we’ll help you learn how to use tokens capabilities. Tokens give developers the ability to represent fungible assets on the ledger. The token SDK does much of the heavy lifting for you on the logic needed for issuance and management of tokens. This capability gives developers a fast way to create tokenized assets on Corda with real world business use cases supported.This is a code first course. We assume you’re familiar with Java and have developed a basic CorDapp. Otherwise, we provide everything you need to develop a tokens enabled CorDapp.
This tutorial will walk you through building a Hyperledger Composer blockchain solution from scratch. In the space of a few hours you will be able to go from an idea for a disruptive blockchain innovation, to executing transactions against a real Hyperledger Fabric blockchain network and generating/running a sample Angular 2 application that interacts with a blockchain network.
This tutorial gives an overview of the techniques and resources available to apply to your own use case.
Note: This tutorial was written against the latest Hyperledger Composer build on Ubuntu Linux running with Hyperledger Fabric v1.0 where referenced below and also tested for a Mac environment.
The document introduces blockchain development on Algorand. It discusses what blockchain is and why developers should care. It covers the types of solutions that can be built on blockchain using programming languages like Python, TEAL, and Reach.

was highly inefficient because supply and demand had to
be exactly matched between peers. To solve the matching
problem, money was introduced as a medium of exchange
and store of value. Initial types of money were not centralized. Agents accepted any number of items such as stones
or shells in exchange for goods. Eventually, specie money
emerged, a form in which the currency had tangible value.
Today, we have non-collateralized (fiat) currency controlled
by central banks. The form of money has changed over time,

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.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
