Module 3: Blockchain Platforms Supporting Staking

Module 3: Blockchain Platforms Supporting Staking

Ethereum 2.0

Transition from PoW to PoS:

1. Understanding the Migration:

  • Motivation for Change: Ethereum's transition from Proof of Work (PoW) to Proof of Stake (PoS) aims to address scalability, energy efficiency, and security concerns. PoW, while secure, is resource-intensive and can handle only a limited number of transactions per second.
  • Phased Upgrade: The transition, known as Ethereum 2.0 or Eth2, is occurring in multiple phases. The initial phase, called Phase 0, introduced the Beacon Chain, which handles PoS-based consensus. Subsequent phases will merge the Beacon Chain with the existing Ethereum mainnet and introduce shard chains to improve scalability.

2. Implications for the Network:

  • Energy Efficiency: PoS significantly reduces energy consumption compared to PoW, as it eliminates the need for intensive computational work.
  • Scalability: With the introduction of shard chains, Ethereum 2.0 aims to process many more transactions per second, reducing congestion and lowering transaction fees.
  • Security: PoS enhances security by making it economically unfeasible for malicious actors to gain control of the network, as they would need to acquire a majority of the staked ETH.

Staking Requirements and Process:

1. Participating in Ethereum 2.0 Staking:

  • Minimum Stake: To become a validator on Ethereum 2.0, participants must stake a minimum of 32 ETH. This stake acts as collateral to ensure honest behavior.
  • Hardware and Software Requirements: Validators need a computer with reliable internet connectivity, a secure operating system, and sufficient hardware specifications to run a validator node. Additionally, validators must run Eth2 client software, such as Prysm, Lighthouse, or Teku.

2. Step-by-Step Guide:

  • Setup: Download and install an Eth2 client. Follow the client’s instructions to set up and configure the validator node.
  • Deposit Contract: Transfer 32 ETH to the Eth2 deposit contract using the official Ethereum launchpad. This step registers your validator with the Beacon Chain.
  • Start Validating: Once the deposit is confirmed, the validator software will begin participating in block proposals and attestations, earning rewards for honest participation.

Example: Using Prysm Client

  • Install Prysm: Follow the installation guide on Prysm’s official website to set up the client.
  • Stake ETH: Use the Ethereum launchpad to stake 32 ETH and register your validator.
  • Run Validator Node: Start the validator node and monitor its performance using the Prysm dashboard.

Cardano

Ouroboros Consensus Algorithm:

1. Unique Features of Ouroboros:

  • Proof of Stake (PoS) Mechanism: Ouroboros is Cardano’s PoS algorithm designed to provide secure and efficient blockchain consensus. It relies on randomly selected leaders to propose new blocks.
  • Epochs and Slots: The algorithm divides time into epochs, which are further divided into slots. Each slot has a designated slot leader responsible for adding a block to the blockchain.
  • Security Proofs: Ouroboros incorporates rigorous security proofs and peer-reviewed research to ensure the robustness and security of the network.

2. Advantages of Ouroboros:

  • Energy Efficiency: By eliminating the need for intensive computations, Ouroboros significantly reduces energy consumption compared to PoW algorithms.
  • Scalability: The algorithm’s design allows for parallel processing of transactions, enhancing the network’s scalability.
  • Security: Ouroboros ensures security through randomness in leader selection and cryptographic protocols that protect against attacks.

Staking Pools and Delegation:

1. How Staking Pools Work:

  • Pool Operators: Staking pools are managed by operators who run the pool’s node and infrastructure. They aggregate the stakes of multiple delegators to increase the chances of being selected as a slot leader.
  • Delegators: ADA holders who do not wish to run a validator node can delegate their stake to a staking pool. Delegators earn a portion of the rewards based on their contribution to the pool.

2. Delegating Stake:

  • Choose a Pool: Use Cardano’s Daedalus or Yoroi wallet to browse and select a staking pool. Factors to consider include the pool’s performance, fees, and reputation.
  • Delegate ADA: Delegate your ADA to the chosen pool through the wallet interface. The delegation process is straightforward and can be reversed or changed at any time.
  • Earn Rewards: Delegators receive staking rewards proportional to their stake in the pool, distributed at the end of each epoch.

Example: Using Daedalus Wallet

  • Download Daedalus: Install the Daedalus wallet from the official Cardano website.
  • Choose a Pool: Browse available pools in the wallet’s delegation center and select one based on your criteria.
  • Delegate Stake: Follow the prompts to delegate your ADA to the chosen pool and start earning rewards.

Polkadot

Nominated Proof of Stake (NPoS):

1. Overview of NPoS:

  • Hybrid Model: Polkadot’s NPoS combines elements of PoS and DPoS. It relies on both validators and nominators to secure the network.
  • Role of Nominators and Validators: Nominators stake their DOT tokens to support multiple validators, who are responsible for validating transactions and adding new blocks. Validators are chosen based on the combined stake of their nominators.

2. Validator Selection and Responsibilities:

  • Becoming a Validator: To become a validator, participants must stake a significant amount of DOT and meet technical requirements, including running a validator node with reliable hardware and internet connectivity.
  • Responsibilities: Validators validate transactions, produce new blocks, and participate in consensus. They are rewarded for their contributions but can be penalized (slashed) for malicious behavior or poor performance.

Example: Nominating with Polkadot.js

  • Access Polkadot.js: Use the Polkadot.js browser extension to manage your DOT tokens.
  • Select Validators: Browse the list of available validators and nominate those with a good track record and low commission rates.
  • Stake DOT: Stake your DOT tokens by nominating your chosen validators and start earning rewards.

Other Notable Platforms

1. Tezos:

Overview of Staking Mechanism:

  • Liquid Proof of Stake (LPoS): Tezos uses LPoS, where validators, known as bakers, are selected based on the amount of XTZ they and their delegators have staked.
  • Baking and Endorsing: Bakers create new blocks (baking) and validate blocks created by others (endorsing). Both activities are rewarded.

Participation Process:

  • Become a Baker: To become a baker, participants must have a minimum stake of 8,000 XTZ and run a node.
  • Delegation: XTZ holders can delegate their tokens to a baker without transferring ownership, earning rewards while maintaining control of their assets.

Example: Using TezBox Wallet

  • Download TezBox: Install the TezBox wallet from the official Tezos website.
  • Delegate XTZ: Use the wallet to delegate your XTZ to a baker of your choice and start earning rewards.

2. Cosmos:

Overview of Staking Mechanism:

  • Tendermint Consensus Algorithm: Cosmos uses the Tendermint algorithm, a Byzantine Fault Tolerant (BFT) PoS consensus mechanism.
  • Validator Nodes: Validators propose and validate new blocks, securing the network through staking.

Participation Process:

  • Becoming a Validator: Validators must meet hardware and staking requirements. They are chosen based on the amount of ATOM staked.
  • Delegation: ATOM holders can delegate their tokens to validators and earn rewards proportional to their stake.

Example: Using Keplr Wallet

  • Install Keplr: Download the Keplr wallet from the official Cosmos website.
  • Delegate ATOM: Delegate your ATOM tokens to a trusted validator through the wallet interface.

3. Solana:

Overview of Staking Mechanism:

  • Proof of History (PoH) and PoS: Solana combines PoH, which provides a historical record of events, with PoS for consensus.
  • Validator Network: Validators process transactions and add new blocks, earning rewards for their participation.

Participation Process:

  • Becoming a Validator: Validators must meet technical requirements and stake SOL tokens.
  • Delegation: SOL holders can delegate their tokens to validators and receive staking rewards.

Example: Using SolFlare Wallet

  • Install SolFlare: Download the SolFlare wallet from the official Solana website.
  • Delegate SOL: Delegate your SOL tokens to a validator and start earning rewards.
