Staking in Cardano

A welcome post by the “Architect of Staking”: Prof Aggelos Kiayias (Chief Scientist, IOHK), which acknowledges the importance of pledging in the protocol in order to achieve the objectives of the Cardano ecosystem:

Engage all stakeholders – This is important since the more stakeholders are engaged in the system, the more secure the distributed ledger will be. This also means that the system should have no barriers for participation, nor should impose friction by requiring off-chain coordination between stakeholders to engage with the mechanism. 

Keep the leverage of individual stakeholders low -. Pooling resources leads to increased leverage for some stakeholders. Pool operators exert an influence in the system proportional to the resources controlled by their pool, not to their own resources. Without pooling, all resource holders have leverage of exactly 1; contrast this e.g., to a pool operator, owning, say 100K ada, who controls a pool of total delegated stake of 200M ada; that operator has leverage of 2,000. The higher the leverage of the system, the worse its security (to see this, consider that with leverage above 50, launching a 51% attack requires a mere 1% of the total resources!).

He continues:

So how does the reward sharing scheme used in Cardano meet the above objectives? Staking via our scheme facilitates two different paths: pledging and delegating. Pledging applies to stake pool operators; pledged stake is committed to a stake pool and is supposed to stay put for as long as the pool is operating. Think of pledge as a ‘commitment’ to the network – ‘locking up’ a certain amount of stake in order to help safeguard and secure the protocol. Delegating on the other hand, is for those who do not wish to be involved as operators. Instead, they are invited to assess the offerings the stake pool operators provide, and delegate their stake to one or more pools that, in their opinion, best serve their interests and the interest of the community at large. Given that delegation does not require locking up funds, there is no reason to abstain from staking in Cardano; all stakeholders can and are encouraged to engage in staking.

The articles continues with guidance for delegators and SPO’s. We are pleased to say that ADAvault is already operating in line with the guidance offered.
