  • The Operation Principle of Polkadot Relay Chain

    The future of Polkadot is a huge heterogeneous sharding architecture. in this huge structure. The relay chain is the central chain of Polkadot. All validators of Polkadot’s DOT are staked on the relay chain and verified for the relay chain. There are relatively few transaction types on the relay chain: governance mechanism interactions, parachain auctions, NPoS. The relay chain does not support smart contracts. The main responsibility is to coordinate the entire system and parachains. Other specific work is delegated to parachains with different functions. Polkadot can support multiple execution slots. These sockets are like the cores on…

  • Polkadot v1.0: Sharding and Economic Security

    This article is about the technology that underpins Polkadot. Polkadot is a sharded blockchain with heterogeneous shards. Sharding in this context means splitting work across multiple sub-blockchains, called parachains. Heterogeneity means that each blockchain has its own state transition function built for a specific use case. Different types of transactions will have different attributions, which allows the chain for a specific scenario to serve its users most efficiently. Polkadot provides security and messaging capabilities for all parachains. This article is primarily written for technical readers who have some understanding of blockchain consensus. I hope it is…

  • Gavin’s latest interview: Web3 decentralized technology is the only hope for maintaining freedom and democracy

    Gavin Wood coined the term Web3 in 2014. He believes that decentralized technology is the only hope for maintaining freedom and democracy. Have you ever questioned “What is Web3.0?”. This view has been around for some time, whether you are through venture capital, media interpretation, or some incomprehensible company interpretation. But it’s hard to say what all the hype is about.
