バベルフィー - トランザクションコストをネイティブトークン建てに

ダグラス・アダムズの古典『銀河ヒッチハイク・ガイド』で、バベルフィッシュはどんな言語でも母国語に翻訳してくれる生き物です。このファンタジックな普遍的翻訳により、宇宙で無数に存在する言語の違いにも拘わらず、意義のあるやり取りが確保されます。

暗号通貨の世界では、スマートコントラクトのプラットフォームは無数のカスタムトークンの開発を可能にします。では、自分好みのトークンを使ってプラットフォームとやり取りすることは可能なのでしょうか。「バベルフィー」メカニズムがあれば、任意のトークンをプラットフォームがトランザクションを送信するために必要とする形式に翻訳することができます。

Blockchain reward sharing - a comparative systematization from first principles

Navigating the diverse landscape of reward-sharing schemes and the choices we have made in the design of Cardano’s reward-sharing scheme

Blockchain reward sharing - a comparative systematization from first principles

In the previous article, we identified the objectives of the reward scheme in Cardano, and we gave general guidelines regarding engaging with the system.

Taking a more high-level view, we will examine from first principles, the general problem of reward sharing in blockchain systems. To recall, the two overarching objectives of any resource-based consensus system is to…

The general perspective on staking in Cardano

As a project, decentralization remains arguably our most important and fundamental goal for Cardano. Protocols and parameters provide the foundations for any blockchain. Last week, we outlined some of the planned changes around Cardano parameters and how these will impact the staking ecosystem and thus accelerate our decentralization mission.

Yet the community itself – how it sees itself, how it behaves, and how it sets common standards – is a key factor in the pace of this success. Cardano has been very carefully engineered to provide “by design” all the necessary properties for a blockchain system to operate successfully. However, Cardano is also a social

The Ouroboros path to decentralization

Designing and deploying a distributed ledger is a technically challenging task. What is expected of a ledger is the promise of a consistent view to all participants as well as a guarantee of responsiveness to the continuous flow of events that result from their actions. These two properties, sometimes referred to as persistence and liveness, are the hallmark of distributed…

Enter the Hydra: scaling distributed ledgers, the evidence-based way

Scalability is the greatest challenge to blockchain adoption. By applying a principled, evidence-based approach, we have arrived at a solution for Cardano and networks similar to it: Hydra. Hydra is the culmination of extensive research, and a decisive step in enabling decentralized networks to securely scale to global requirements.

What is scalability and how do we measure it?

Scaling a distributed ledger system refers to the capability of providing high transaction throughput, low latency, and minimal storage per node. These properties have been repeatedly touted as critical for the successful deployment of blockchain protocols as part of real-world systems. In terms of throughput, the VISA network reportedly handles an average of 1,736 payment transactions per second (TPS) with the capability of handling up to 24,000 TPS and is frequently used as a baseline comparison. Transaction…
