Ensuring ETC network security - a comparison of 51% Attack Resistance proposals for Ethereum Classic
23 October 2020 4 mins read
The Ethereum Classic network suffered from four 51% attacks between 2019 and 2020. Three of those attacks have occurred recently – with just weeks between each other – which resulted in expensive losses for stakeholders due to double spending and service disruption. A number of Ethereum Classic Improvement Proposals (ECIPs) followed after these attacks aiming to provide the…

Marlowe: industry-scale financial smart contracts for the blockchain
Move over Solidity – this specialized language will bring decentralized finance to Cardano
6 October 2020 5 mins read
In this post, we introduce Marlowe, a new language for financial contracts, and describe the benefits of it being a domain-specific language (DSL). As a DSL it describes only financial contracts, rather than smart contracts in general. Because of this, it differs from general-purpose blockchain languages like Solidity and Bitcoin Script.
Marlowe is industry-scale. We have built Marlowe contracts based on examples from one of the leading projects for financial smart contracts, the Algorithmic Contract Types Unified Standards (Actus) system. Currently, these and other examples can be seen in the Marlowe Playground…
Developer challenge: using blockchain to support the UN’s sustainable development goals
IOHK has set up a $10,000 fund to invest in ideas for sustainable development based on Cardano.

Creating a decentralized financial and social operating system for the world is the core mission of Cardano. But it’s not one that we can accomplish alone. That’s why we are always on the lookout for relationships which help us build a global foundation for growth. So, we’re thrilled to announce our hackathon challenge to support the UN’s sustainable development goals (SDGs…
