What are the third generation blockchain platforms?

The third-generation blockchain platform solves the limitations of the previous-generation platform by improving the consensus mechanism and architecture: Scalability: DAG technology and sharding technology improve processing capabilities. Privacy: Zero-knowledge proof and ring signature hide transaction information and protect privacy. Interoperability: Cross-chain protocols and universal virtual machines support cross-blockchain communication and interaction. Other improvements: Programmability, consensus mechanism optimization to improve customization and efficiency.

The third generation blockchain platform

The third generation blockchain platform aims to solve the problems faced by early platforms scalability, privacy, and interoperability limitations. These platforms achieve these improvements by adopting new consensus mechanisms and architectures.

Scalability

• DAG (Directed Acyclic Graph): Platforms such as IOTA and Nano use the DAG structure to allow parallelism Process transactions, thereby improving scalability.
• Sharding: Platforms such as Zilliqa and Polkadot divide the network into shards, with each shard processing a specific set of transactions, enhancing scalability.

Privacy

• Zero-knowledge proofs: Platforms such as Zcash and Harmony use zero-knowledge proofs to hide transaction amounts and sending recipient information, thereby protecting privacy.
• Ring signature: Monero uses ring signatures to combine the signatures of multiple users involved in a transaction into a single signature, making it difficult to track individual transactions.

Interoperability

• Cross-chain protocol: Platforms such as Polkadot and Cosmos provide cross-chain protocols that allow different Communicate and interact with assets and data on the blockchain.
• Universal Virtual Machine: Platforms such as Solana and Near provide universal virtual machines that allow developers to deploy smart contracts on multiple blockchains to improve interoperability.

Other Improvements

• Programmability: Platforms such as Cardano and Tezos allow higher level control over the underlying protocol Customize and update.
• Consensus Mechanism: The third generation platform explores various consensus mechanisms such as Proof of Stake (PoS) and Delegated Proof of Stake (DPoS) to improve efficiency and decentralization.

Example

• IOTA: A DAG-based platform focused on Internet of Things (IoT) scalability and privacy.
• Polkadot: An interoperable multi-chain platform that provides a framework for connecting different blockchains to each other.
• Zcash: A privacy-focused platform that uses zero-knowledge proofs to enable anonymous transactions.
• Solana: A high-performance platform that leverages sharding and proof-of-history to improve scalability.
• Cardano: A research-driven platform with a focus on programmability and security.
