What is the Consensus Mechanism of Celestia (CELT) Currency?

Celestia (CELT) is a blockchain platform that provides a decentralized infrastructure for rollups, enabling scalability and data availability for Ethereum applications. Its innovative consensus mechanism, dubbed "Proof-of-Stake Bonded Consensus" (PoSBoC), plays a crucial role in maintaining the network's security, efficiency, and decentralization.

Understanding Proof-of-Stake Bonded Consensus (PoSBoC)

To grasp PoSBoC, it's essential to comprehend the fundamental principles of Proof-of-Stake (PoS) protocols. In PoS, validators are selected to create and validate blocks based on their staked tokens. The probability of being chosen is directly proportional to the number of tokens staked, incentivizing validators to contribute to the network's security.

PoSBoC extends the PoS paradigm by introducing bonded consensus, an additional layer of security. Validators in Celestia are required to stake CELT tokens as a bond, which acts as collateral against malicious behavior. If a validator engages in dishonest activities, a portion of their staked CELT tokens can be slashed, disincentivizing misconduct and ensuring network integrity.

Role of Nodes in PoSBoC

The Celestia network comprises two types of nodes:

1. Data Availability Committee (DAC) Nodes: DAC nodes are responsible for storing and validating transaction data. They form a distributed network that ensures the availability and integrity of data.
2. Consensus Nodes: Consensus nodes are responsible for ordering and finalizing transactions. They propose and vote on new blocks to extend the blockchain, leveraging the PoSBoC consensus mechanism.

Steps in PoSBoC

PoSBoC operates through a series of distinct steps:

• Random Validator Selection: Validators are randomly selected based on their staked CELT tokens.
• Block Proposal: Selected validators propose new blocks containing transactions submitted by users.
• Block Validation: Other validators validate the proposed blocks by checking their validity and consistency with the blockchain's history.
• Block Finalization: If the block receives a sufficient number of votes from validators, it is considered finalized and added to the blockchain.
• Slashing: If a validator engages in malicious activities, a portion of their staked CELT tokens is slashed as a penalty, ensuring accountability and disincentivizing misconduct.

Benefits of PoSBoC

PoSBoC offers significant advantages for the Celestia network:

• Security: Bonded consensus adds an additional layer of security, as validators risk losing their staked CELT tokens for malicious behavior.
• Scalability: By enabling rollup technology, PoSBoC helps scale Ethereum applications, increasing transaction throughput while maintaining data availability.
• Decentralization: The random selection of validators and the slashing mechanism promote a decentralized and fair consensus process.
• Energy Efficiency: PoSBoC consumes significantly less energy compared to Proof-of-Work (PoW) protocols, contributing to environmental sustainability.
