It’s well known that blockchain offers significant promise to enterprises.  What’s less well known is that the development of most enterprise use cases get stuck due to the challenges of new Web3 programming models and to tackling the multi-party data flows, tokens, privacy and more.  The blockchain itself accounts for just 5-10% of a multi-party business process, while cross-party data flows make up as much as 75% of the solution.

Learn how to build digital assets and multiparty systems for enterprise data flows, powered by blockchain. Leverage enterprise APIs and services to build blockchain apps for enterprise radically faster by allowing you to focus on business logic instead of low-level web 3 plumbing.

In this workshop, we'll give a brief introduction to Kaleido platform and Hyperledger FireFly open source technologies and how these can rapidly accelerate the adoption of blockchain technology in the enterprise arena. The workshop will also feature hands-on-keyboard use of FireFly APIs to help developers get started building.

IBM, Senior Technical Staff Member Open Technnologies

Hyperledger Fabric is the most popular framework for developing blockchain applications for the enterprise. This session will present its unique characteristics, some of the use cases it is designed for, and discuss the latest developments and what's yet to come. Attendees will leave with the information they need to get started developing their own applications with Fabric.

OPEN TALK: How to Onboard the Next Billion into Web3 with Magic

Magic, CEO & Co-founder

Magic is more than just a plug-and-play passwordless auth that enables a delightful onboarding experience for end-users.

Instead of usernames and passwords, Magic uses blockchain-based public and private keys to authenticate users under the hood. A decentralized identifier is signed by the private key to generate a valid authentication token that can be used to verify user identity.

Traditionally, usernames are publicly recognizable identifiers that help pinpoint a user, whereas passwords are secrets that were created by the user and are supposed to be something only they know.

You can think of public and private keys as materially improved versions of usernames and passwords. The public key is the identifier and the private key is the secret. Instead of being created by users and prone to human error (e.g. weak/reused passwords), the key pair is generated via elliptic curve cryptography that has proven itself as the algorithm used to secure immense value sitting on mainstream blockchains like Bitcoin and Ethereum.

Using blockchain key pairs for authentication gives Magic native compatibility with blockchain, supporting over a dozen of blockchains. This enables web3 developers to use Magic SDK to provide user-friendly onboarding experiences to mainstream users and tap into the potential of the rapidly expanding blockchain industry that is growing 56.1% year over year and projected to reach $69.04 billion by 2027.

The key pairs are also privacy-preserving (no personally identifiable information) and exportable. This allows user identity to be portable and owned by users themselves (self-sovereignty). The world is already moving towards this direction with novel solutions from companies like Workday and Microsoft.

As a first step, we are committed to enabling a passwordless future, by providing developers with the easiest way to integrate passwordless login methods into their apps, but having blockchain key-pairs actually connects us to other future-proof infrastructure such as IPFS for decentralized user identity data storage, which will pave the way towards worldwide adoption of decentralized identity.

If you want to see just how seamless both the developer and user experiences are with Magic, or you want to learn how Magic plans to onboard the next billion users into web3, do not sleep on this talk.

OPEN TALK: The Open Source Path to Developing Enterprise Blockchain Platforms and Tools

Accenture, Technology Architect Manager

Enterprise blockchain is a team sport. The technology serves as shared de facto infrastructure for stakeholders across and between organizations. Community-built DLTs serve as the foundation for decentralizing critical processes and creating transparent operations with trust built in at the core.

Increasingly, enterprises are looking to deploy blockchain platforms in larger systems and more complex solutions. This means integrating with other systems and even other blockchains. The open source development model is now delivering on a new generation of tools and technologies to make deployments simpler, to help networks interoperate and more.

In this talk, David Boswell, Senior Director of Community Architecture at the Hyperledger Foundation, will sit down with Hart Montgomery of Fujitsu and Peter Somogyvari
from Accenture, two long-time leaders in the Hyperledger developer community, to talk about how development happens in the open source community and the latest developments in the current enterprise blockchain ecosystem. Hart and Peter are contributors to Hyperledger Cactus, a blockchain integration tool designed to allow users to securely integrate different blockchains. They are also members of the Hyperledger Technical Steering committee. The discussion will cover:

- Business and technical drivers for expanding blockchain networks into extensible multiparty systems capable of exchanging data in secure, transparent ways across a mix of platforms
- The growing pipeline of technologies for cross chain, off chain and legacy system interoperability
- The value of an open ecosystem in driving innovation and trusted software
- The opportunities to get involved in the community of communities developing and deploying the increasingly diverse technologies in the enterprise blockchain space

OPEN TALK: Demystifying NFTs
Join on Hopin
Tejas Chopra
Tejas Chopra
Netflix, Senior Software Engineer

Non-fungible tokens have taken the world of digital art by storm. The growth in NFTs this year is a staggering 1500%+, and is set to revolutionize art & collectibles. In this session, I present the basics of NFTs, and delve into industries disrupted by NFTs: art, collectibles, gaming. I will discuss how to dip your toes into the NFT world by minting your unique collectible as an NFT on platforms such as OpenSea.
NFTs started off on Ethereum blockchain, but soon, Ethereum ran into scalability issues since it only allowed 10-15 TPS. This sparked a surge in different blockchains designed specifically for NFTs, such as WAX, FLOW, etc. We will discuss about how they open up new types of dApps and marketplaces, such as NBA Top Shots.
Finally, we will touch upon some of the perceived environmental impacts of NFTs for users to make informed decisions about platforms they use for trading.

PRO TALK: A Blockchain Interoperability Solution for Creating Token Economies - Hyperledger Cactus

Fujitsu Limited, Senior Researcher

For creating a new token economy beyond financial and non-financial areas, blockchain interoperability has an essential role in interacting with multiple blockchains in various industries. But there are two issues on interacting with numerous blockchains. It is challenging to adjust multiple blockchains because each blockchain has different APIs for posting transactions and getting block data. The other issue is that it is difficult to connect various blockchains because their network setting depends on each blockchain platform.

Hyperledger Cactus is an open-source platform for interconnecting blockchains and activating digital transformation to solve the above issues. Key highlights are the following:
* Absorbed operation: Eliminate the differences such as API calls and the timing of transactions between multiple heterogeneous blockchains
* Bi-directional communication: Enable Cactus to post transactions and get block data via firewall-enabled abstracted operation.
* High availability connectivity: Providing ledger connectivity to 9 ledgers including Go-Ethereum, Quorum, Hyperledger Fabric, Hyperledger Indy, Hyperledger Sawtooth, etc.

Explore the blockchain interoperability experience that accelerates token economies beyond various industries for their business needs. In this session, we will explain the importance of blockchain interoperability in the solutions beyond the industry using Cactus demonstrations about car ownership trades and electricity trades with the combination of Ethereum blockchains and other-typed blockchains.
