Winners Announced at the Hedera21 Virtual Hackathon
Back in January, we signed up to provide DragonGlass as an official development tool at the H21 Hedera Hashgraph Virtual Hackathon. In addition to grand 1st, 2nd, and 3rd place prizes given out by Hedera for overall performance, the Hackathon was comprised of challenges put forth by a variety of sponsors. It was an amazing turnout, with 632 competitors comprising 54 teams across 72 countries. After a month of hard work, we were extremely pleased to see that Asseto, the winner of two separate challenges (DLA Piper and BCW Group Enhancing Tokenization Functionality Challenge, and the University College of London Tokenization Protocol Challenge) heavily utilized DragonGlass to add transfer event information into their Oxiles event bridge. We wanted to personally congratulate Asseto and the rest of the challenge winners - this was truly one of the more exciting and cutting-edge hackathons we have had the honor of participating in.

How to Query Historical Hedera Data with the DragonGlass REST API
Coming to Hedera from a traditional blockchain background, one of the first things users must wrap their heads around is how the network handles state. As a development partner since 2017, we at OpenCrowd are keenly aware that companies building on Hedera need a seamless way to access all of their live and historical data in an operational data store. Additionally, users of these applications may want to access any relevant information about them. These issues are what led us to create the DragonGlass platform.

Hedera Hashgraph launched its public main net on Sep-16th 2019. The network has processed about 20 Million transactions with ease. The good news is that the 10K TPS is just the start and a lot more is yet to come. This public decentralized platform satisfies one of the urgent needs and the most requested requirement that was constraining the building of real life decentralized applications. That need for the last several years has been high throughput and low latency. Hedera Hashgraph was able to meet that need by launching the mainnet.
Hedera’s primary focus is high throughput, high security, governance, no forking and other highly valued needs in the market. While pursuing these high-value needs they have left other developer requirements like data persistence, storage of transactions and retrieval of historical data, and other application specific needs to be developed by the Hedera ecosystem. The Hedera mainnet does not intend to be a long term data store; its focus is mainly managing the current state of the ledger. The vast trail of data produced on the execution of transactions, smart contracts, files etc is expected to be managed by the individual development teams.

The Better Decentralized Network: Hedera Hashgraph Case Study
Hashgraph, an efficient, provable, byzantine fault-tolerant, ACID-compliant ecosystem that can be understood as a faster alternative to current blockchain networks, presents some promising solutions to the problems already mentioned in the previous article. At a very high level, the most promising feature offered by the platform is that it easily fits into the matrix of the current DLT wishlist. There are many attributes that could be attractive for an aspiring decentralized application:
1. Governance Operating Model:
Provides a solution to “death by trivial forking” and keeps the upgrades within the scope of a council. The council comprising of members from unique industries across various different industry segments & geographic regions. This would allow faster decision making cycles on key aspects like software upgrade, fees and compliance. Virtual voting based on a patented algorithm excludes the necessity to do any mining for PoW and hence takes away the race for the reward problem.

As blockchain technology continues to gain traction, companies have quickly become dependent on multiple distributed ledgers. Until recently, if a company wanted to have a smart contract run on multiple blockchains, they would have to write smart contract for each separate blockchain, with each contract written in a different language unique to that blockchain. This is expensive, laborious, and time-consuming for a business. Enterprises using multiple blockchains are better off standardizing on technologies to achieve efficiency, but this has not been possible to date.
To address these issues, DAML was created as a language for developing concise and secure smart contracts that are executed in a standardized format across different private distributed ledgers. DAML is designed to simplify and remove some of the complexities involved in smart contract development, allowing developers to focus on implementing the behavior and logic of created contracts.

Can Blockchain Save the Global Farmer?
World leaders returned to the United Nations yesterday for the second Blockchain for Impact (BFI) global summit. An invite-only event, BFI aims to bring together global dignitaries, founders, and practitioners to help address many of the urgent problems our society faces today, as outlined by the UN’s 17 Sustainable Development Goals (SDGS). The summit served as an opportunity to showcase blockchain use cases for the UN and world governments in areas such as ocean restoration, data privacy, and women in the tech sector workforce, as well as use cases currently being utilized by smaller nation-states Liechtenstein and the Republic of the Marshall Islands (RMI). Speakers included Dr. Hilda Cathy Heine, President of the Republic of Marshall Islands, and Adrian Hasler, Prime Minister of Liechtenstein; Dr. Adonia Ayebare, Ambassador of the Republic of Uganda to the UN; and Dr. Eva-Marie Muller-Stuler, Chief Data Scientist at IBM.

Can Blockchain Save the Global Farmer?
The sentiment of CryptoNouveau event on Bleeker Street during New York Blockchain Week was vibrant in the wake of the latest surge in crypto prices. It appears that many members of the blockchain community buckled down to build product and stayed under the radar while marketing was kept to a minimum. The results speak for themselves; the foundation of decentralized ledger technology has evolved in tremendous strides since last year’s event, and we cannot wait to see how the technology continues to mature in the coming months.

Can Blockchain Save the Global Farmer?
Originally Seen in Medium
The biggest challenge facing farmers worldwide is not global warming, or the threat of crop failure, but the poor quality of capital available to them. Farmers face sustained financial pressure from poor capital terms, and the potential loss of livelihood has caused many to take their own lives. Farmer suicide is now a global crisis that is not limited to developing economies, and can be seen even in developed countries such as Australia, France, and the US.

As Blockchain continues its rise to widespread mainstream adoption, new use cases will continue to arise and spark innovative development. As a Blockchain solutions firm, we get asked almost daily if Blockchain can be used as a regular data store similar to SQL and other common relational database management systems. Almost always our response comes down to the following description of what Blockchain has to offer and how it should be leveraged for specific use cases. As time goes on and increases are made to the scale and transaction speed at which the Blockchain can operate, the use cases for Blockchain will expand into many new fields and scenarios.
Given the state of the current crypto winter, many of us have seen and heard about a large amount of negative sentiments regarding blockchain and its potential to be a truly game-changing technology.
As a team that has been deeply involved in helping clients build solutions with this technology, we foresee some solid momentum with regards to the applicability and feasibility of blockchain-related products. Below are a few of our predictions as to how blockchain will move forward and evolve in 2019.
