In a previous post, Bringing new value and utility to the Cardano blockchain, I discussed the notion of transaction metadata. I also explained why this is crucial to Cardano’s Goguen evolution as a utility platform for decentralized finance (DeFi) operations.

There are many potential uses for metadata. With that in mind, IOHK has been working to ensure that both developers and…

Goguen（ゴーグエン）のロールアウトとともに、Cardanoはスマートコントラクトプラットフォームとなります。処理されるデータに関する情報であるメタデータをトランザクションに追加することがこの鍵となりますが、先月この機能がブロックチェーンに追加されました。トランザクションに焦点が当てられていたCardanoは、今や分散型金融（DeFi）の時代を定義する複雑な操作に対応できる、パートナーシップ、企業、および商用アプリケーションに開かれた、ユーティリティプラットフォームへとシフトしています。

暗号資産の財務運用の規模が拡大するにつれ、特にウェルスマネジメントなどのアプリケーションにとって、変更不可能な不変のデータへのアクセスが可能であることは極めて重要です。Cardano…

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…

Project Catalyst is, at its heart, a series of experiments in innovation and governance. Once it was decided to set up a funded system to encourage innovation for Cardano, the IOHK team decided to collaborate with our global community from the start. So, that’s what we did. Now, with two funds already incubating hundreds of proposals and fostering thousands of conversations, we…

In our Developer Deep Dive series of occasional technical blogs, we invite IOHK’s researchers and engineers to discuss their latest work and insights.

Marlowe is a domain-specific language for secure financial smart contracts that is being developed by IOHK for the Goguen capabilities of the Cardano blockchain. Following my introductory post on Marlowe, in this Deep Dive post…
