An Introduction to Cardano

Cardano is a proof of stake blockchain based on peer-reviewed research and evidence-based models. It will support smart contracts, sidechains, governance, and a voted-upon treasury system once fully launched.

This full launch of Cardano will be executed in five phases:

  • Byron: core of the protocol
  • Shelley: progressive decentralization
  • Goguen: multi-asset and smart-contract development
  • Basho: scalability and side-chain enablement
  • Voltaire: governance and voting

The protocol is currently operating in a limited live mainnet within the Shelley phase. At full launch, its core features will include:

  • Plutus, a purpose-built smart contract development language to improve the coherency and usability of the development experience compared to existing smart contract implementations. This improvement is achieved by use of the functional programming language Haskell, which allows one codebase to support both on- and off-chain components.
  • Marlow, a high-level domain-specific language for financial contracts built on Plutus. Financial and business experts with no previous technical knowledge can create and execute smart contracts with Marlow.
  • More than 1,000 stake pools to enhance engagement and decentralization.
  • Sidechains to expand the throughput, capacity, and capabilities of the network for a variety of diverse use cases.
  • Decentralized governance, funded by a treasury of pooled transaction fees and rewards to support development activities, allowing anyone to make a proposal that can be voted on through governance and funded by the community.

You can learn more about Cardano in our guide.


How to participate on Cardano

Cardano uses a novel proof of stake consensus mechanism, Ouroboros. Ouroboros is considered secure as long as 51% of the stake is controlled by entities who are not misbehaving, as opposed to the 67% control required by the majority of proof of stake protocols.

The main participants in the Cardano network are core nodes and relay nodes, which together comprise a stake pool.

  • Core nodes function as protocol validators, connecting only to their relay nodes and holding the certifications needed for block generation.
  • Relay nodes act as the interface between validator nodes and the public network, enhancing security for validators.

The d and k parameters, protocol-defined variables that influence Cardano’s stake pools, are an important aspect of Cardano’s staking dynamics and level of decentralization.

  • The Decentralization Parameter (d) impacts the amount of work (block validation) that stake pools other than the Federation of Nodes are performing within the network
  • The Saturation Parameter (k) controls the number of stake pools by capping the amount of ADA that can be delegated to an individual stake pool
    • The d parameter controls the ratio of work completed by the “Federation of Nodes,” or the original three nodes running Cardano in its early phases, to the work completed by other stake pool operators. As the value of the d parameter decreases, the amount of work completed by stake pool operators at large increases, moving the network toward further decentralization. The value was set to decrease by .02/epoch, and in March of 2021, reached 0, bringing Cardano to its fully decentralized launch.

      The k parameter controls the number of stake pools in the network by way of adjusting the maximum amount of ADA that can earn rewards when staked to an individual pool (the stake cap). The higher the k parameter, the lower the maximum stake cap per pool. This incentivizes operators and delegators to distribute their tokens across a larger number of stake pools, further increasing decentralization.

      For example, if the k parameter was set to a 100 ADA cap per pool, a stake pool with 100 ADA and a stake pool with 200 ADA would both earn the same rewards. Currently there are upwards of 1100 stake pools participating on the network protocol at any particular time, and a k value of 500.

      There is no active set for proof of stake validation on Cardano. In the long run, the intention is to set the k parameter to optimize the participation of 1000 stake pools.

      ADA holders who want to participate in Cardano without becoming a stake pool operator can delegate. There is no minimum requirement for delegation, outside of having enough ADA to cover the transaction fees—in order to ensure one has enough ADA to cover those fees the protocol does require a user to have at least 10 ADA in their wallet in order to delegate. There is no lock up or unbonding period for delegating within Cardano; delegators can unbond their tokens at any time. Delegators can also change their stake pool at any time, and may divide their ADA delegation between as many stake pools as they would like by creating split wallet addresses within individual wallet UIs.

Rewards on Cardano

Stake pools earn fees from delegators for conducting the service of validation. There are two distinct fees, a fixed fee (the Pool Cost) and a variable percentage fee (the Pool Margin). The Pool Cost, a fixed amount of ADA the stake pool retains from rewards each epoch, provides stake pool operators with a regular, stable reward amount, instilling confidence in the value of continuing to operate a stake pool. The Pool Margin, a percentage of rewards post-fixed fee, allows a stake pool operator to scale their earnings with their pool’s success.

Cardano network’s inflationary rewards process has multiple steps:
  1. Identify total possible rewards: The maximum possible rewards that can be earned within the network each epoch are identified using a parameter called the Expansion Rate. This rate is applied to the Reserve* to determine how many ADA are used for epoch rewards and funding the treasury.

    Currently the Expansion Rate is set to .3%. As such, each epoch .3% of the Reserve is identified as being the potential total possible rewards and the treasury cut for that epoch.

    * The Reserve = Maximum Supply of ADA - ADA currently in circulation & treasury

  2. Pay into the treasury: A predetermined percentage of the total possible rewards are paid into the treasury. As of November 2020, this number was 20% each epoch out of the .3% of the Reserve identified for total possible rewards; for an epoch at that time roughly 8.3m ADA went into the treasury, leaving 33.1m ADA available for staking rewards.
  3. Figure out how much goes to delegators: Inflation is distributed differently in Cardano than in other proof of stake protocols, as the inflation rate is equal to the reward rate. If there are 33.1m ADA in potential rewards for stakers (after the treasury fee is subtracted), the protocol initially assumes this amount will be distributed equally amongst all token holders. However, when it discovers less than 100% of ADA tokens are staked, then tokens that would have been distributed to non-staked tokens are sent back to the Reserve.

There is no mandatory self-bond on Cardano, which instead uses a pledging mechanism. Pledging is an optional self-bond that increases the reward rate experienced by the stake pool and, most importantly, functions as a mechanism to prevent Sybil Attacks on the Cardano Network.

Stake pool operators are rewarded for pledging their own ADA to their own stake pool. The higher the pledged amount, the higher the reward rate for the pool. A stake pool that reaches its stake cap with no ADA pledged earns only 77% of the rewards that a stake pool composed completely of pledged ADA earns. The stake pool operator is therefore incentivized to self-bond via pledging and thus prevent the likelihood of a Sybil attack.

Pledging is also the key to optimizing rewards on Cardano. The higher the pledged amount, the higher the reward rate experienced by the pool. For operators with low delegation expectations can optimize rewards by pledging the whole stake cap for their stake pools. Operators who expect to draw a significant amount of delegated tokens can determine the best delegation fee to optimize the return for delegates and themselves, thus increasing participation.

More information about Cardano’s rewards structure, including examples and information about inflation and staking, can be found in our guide.

Risks of participation on Cardano

There is no slashing within the Cardano protocol. However, poor behavior can cause a node to miss out on potential rewards. The most common penalties are for:

  • Missing blocks: the more block production missed by a stake pool, the lower the reward rate that epoch for the stake pool.
  • Lack of pledged ADA: a stake pool at its stake cap with no pledged ADA earns only 77% of the rewards that a stake pool composed completely of pledged ADA earns.

Governance on Cardano

There is no on-chain governance in the current phase of Cardano (Shelley). The Voltaire phase of Cardano’s launch will focus on proposing, experimenting with, and implementing a decentralized governance model for the protocol to set a voting and treasury system.

Cardano Improvement Proposals (CIPs) are one of the first implementations of off-chain governance for Cardano. CIPs are led by the Cardano Foundation, which was founded with the mission of overseeing and supervising the advancement of Cardano and is focused on core development and ecosystem growth for the protocol.

A CIP is a structured design document that is accessible to the Cardano community via a Github repository overseen by the Cardano Foundation. In the current phase, the Cardano Foundation controls and implements Cardano core development. However, CIPs are used to propose new features, collect community input on an issue, and document the design decisions that go into building the protocol.

The Voltaire phase of development will enable network participants to propose CIPs. Cardano stakeholders will have the ability to vote on their implementation in alignment with the protocol’s staking and delegation process.

Funding proposals are in-development for off-chain governance of the Cardano treasury. Community members will be able to make proposals aimed at enhancing the Cardano ecosystem, such as developing new integrations or funding platform development. The proposals will be voted on by any ADA holder via a currently unreleased mobile application, with the most successful proposals receiving treasury funding.
