Plutus and Marlowe in the spotlight at WyoHackathon 2019

The Cardano network was engineered to be the best possible foundation for the future of decentralized technology – but a foundation is only as good as what can be built upon it. Smart contracts are one of the most powerful ways a distributed network can generate value, allowing individuals and organizations to agree to conditions and automatically execute exchanges of information and wealth, all in a trustless way without relying on third parties. But smart contracts are still code, which means that the languages and tools they’re written with make a difference to their final level of security, efficiency, and reliability.

That said, understanding the potential of smart contracts is different from realizing their integration and adoption. Existing smart contract languages provide the basis for a solution, but are not the final answer. Current smart contracts are complex and difficult to program, partly because they’re built with languages created at the emergence of distributed technologies, and are vulnerable to malicious actors. Blockchain technology has changed drastically since it first emerged, and the conditions that underpinned the first languages are no longer true. The first answer to a problem is rarely the best, and any enterprise-focused solution cannot be gated by complexity or threaten network security.

Bringing functional programming to smart contracts with Plutus

We’re big fans of functional programming here at IOHK and are proud to be able to say that the code underpinning the Cardano network is written in Haskell, the world’s foremost functional programming language. Plutus is no different. Compared to their object-oriented counterparts, functional programming languages are less prone to ambiguity and human error – always a good thing – as well as being easier to verify and test. By using Plutus to write smart contracts on the Cardano network, developers benefit from all of the above, as well as the ability to use the same language for both on and off-chain code.

While developers will have to wait for the Goguen era to launch smart contracts on the Cardano network, they can begin testing their smart contract skills in the Plutus Playground. IOHK has also created a Plutus ebook and Udemy course to help developers hit the ground running once Plutus is available on the Cardano mainnet.

And bringing Plutus to everyone with Marlowe

The problem with smart contracts, however, is that sometimes the people who know how to write the code don’t have the industry expertise to know how to structure the contracts themselves. Enter Marlowe, IOHK’s domain-specific language (DSL). Marlowe is designed for use by anyone that wants to write a financial smart contract without the programming skills to implement it. Users can try out Marlowe via the Marlowe Playground, a web utility with a user-friendly GUI and drag and drop components, where they can create financial smart contracts which, when complete, will generate fully-functional, implementation-ready Plutus code.

Marlowe gives anyone the ability to gain familiarity with smart contracts while protecting them from unexpected outcomes. It also protects the developer and the system by ensuring that ill-formed smart contracts cannot be run. Finally, Marlowe focuses on commitment-of-funds and time-outs. These make certain that both parties have dedicated funds in the agreement while ensuring that money will not be left in the system after a contract has concluded.

Laying solid foundations

Plutus, Marlowe, and the Cardano ecosystem continue to evolve to provide the safest and most efficient conditions to build decentralized applications. The next generations of Plutus and Marlowe will be announced at the WyoHackathon at the University of Wyoming on September 20, ahead of their release on mainnet at the start of the Goguen era. Marlowe advances include a high-fidelity development system that aids the writing of executable contracts and the new iteration of Plutus will allow users to access their contracts from web or mobile applications. To get the latest news from the event, you can follow the WyoHackathon’s Twitter feed.

At IOHK, we're focused on creating the safest, most efficient platform for the building of decentralized applications. Plutus and Marlowe will be the first building blocks to be placed on the foundation which is the Cardano network – and they won't be the last. With this new suite of accessible, inclusive tools, Cardano becomes more capable of serving the diverse audiences that stand to benefit from a secure, decentralized network platform.

IOHK brings Plutus to Wyoming's hackathon

Cardano engineers introduce next phase of the smart contract platform to the Cowboy State

IOHK brings Plutus to Wyoming's hackathon

The state of Wyoming is famous for being part of the American frontier, but it has also established a new reputation, with blockchain pioneers blazing trails in the Cowboy State. But why Wyoming?

The blockchain revolution in Wyoming is the result of a series of laws and regulations passed within its borders. These key pieces of legislation include exemptions from money transmitting laws for virtual assets, as well as a blockchain ‘sandbox’ bill that would allow decentralized businesses to operate free from the red tape encountered elsewhere in the US. The state is also home to the Wyoming Blockchain Coalition, headed by former Wall Street corporate financier Caitlin Long, which has worked to make Wyoming the standard-bearer of blockchain in the country.

In 2018, IOHK relocated its headquarters to Wyoming to take advantage of the state’s legislative embracing of distributed ledger technology, making it the biggest decentralized company in the state. As a result, IOHK has become a nexus for developers, crypto enthusiasts, businesses, and government officials in the area. Events like the 2019 WyoHackathon bring these groups together to advance the cutting edge of blockchain innovation.

‘We’re thrilled to welcome the Cardano community to this special event in IOHK’s home state,’ says Caitlin Long. The event has also inspired a group of high school students from a remote part of Wyoming to make the journey to participate in the hackathon and meet IOHK CEO, Charles Hoskinson. ‘There is something special building between the University of Wyoming computer science department and Cardano!’ she adds.

The hackathon will see hundreds of developers participating in workshops, presenting papers, and acquainting themselves with new technology. Charles Hoskinson and Cardano’s senior product manager David Esser will be among the speakers at the event, alongside prominent leaders in the blockchain industry such as Jesse Powell of Kraken and Anthony Pompliano of Morgan Creek Digital. September marks the second anniversary of the Cardano project and is a milestone for IOHK, with several major advances to Cardano being delivered. Plutus engineers Jann Müller and Michael Peyton Jones will be at the event to explain how work on Cardano is progressing to create the ideal environment for smart contract development and execution.

Last but certainly not least, the next iteration of the Plutus framework will be released during the hackathon. Plutus is a functional programming language and smart contract platform that allows developers of all kinds to launch smart contracts on the Cardano network. While Ethereum paved the way for programmable blockchains, it also has some significant barriers to entry. IOHK aims to bring greater scalability, sustainability, and interoperability to the crypto sphere by allowing anyone to build on a distributed ledger. Ultimately, it is developers that will build the businesses which will solve local and international problems. Plutus was created to enable those developers, and is supported by an IOHK-created [programming book](https://www.amazon.com/Plutus-Writing-reliable-smart-contracts-ebook/dp/B07V46LWTW "Plutus ebook on Amazon, amazon.com").

Both Wyoming and IOHK have aligned their interests in supporting the next generation of thinkers in distributed ledger technology. Events like the hackathon help to inspire and elevate those who will build the decentralized infrastructure of the future. We hope that the 2019 WyoHackathon will be another pioneering step on the road towards better, more comprehensive adoption and use of both blockchain and crypto technology.
