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

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
Advice for Stakeholders - Delegators and Stake Pool Operators.

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…

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…

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…

In a proof of stake (PoS) blockchain protocol, the ledger is maintained by the stakeholders that hold assets in that ledger. This allows PoS blockchains to use less energy compared with proof of work (PoW) or other types of blockchain protocols. Nevertheless, this requirement imposes a burden on stakeholders. It requires a good number of them to be online and maintain…
