  • Say no to vendor lock-in: establish an open cross-chain bridge standard for native assets

    In this era when smart contract compatible chains are springing up like mushrooms, users’ demand for third-party cross-chain bridges of various native assets is also increasing. Blockchain ecology and projects usually adopt simple “mint & burn” cross-chain solutions, which will result in unlimited control of cross-chain assets belonging to a single cross-chain bridge supplier. However, few people have discussed that once the supplier is bound, it is easy to cause huge risks to asset security and blockchain ecology that are difficult to remedy. In this article, we will first discuss…

  • Running BSC, Ethereum, Polygon archive nodes: what is the difference?

    What is special about running an archive node, and who might need this option? Generally, modern blockchains use three types of nodes, namely full nodes, archive nodes, and light nodes. Here are the differences between them-and which applications should integrate Binance Smartchain, Polygon or Ethereum Archive Node. Running BSC, Ethereum, Polygon archive nodes: the basics In programming science, “node” should refer to software/hardware structure, basic unit or data point. In blockchain theory, nodes are actually part of the blockchain: their interactions are preserved by various consensuses. In order to allow…

  • The role of the blockchain index protocol

    The blockchain is a decentralized ledger. The ledger records data, but what you see in the browser is that after the transaction is packaged into blocks, the transaction data becomes a hash. Under the effect of Ethereum’s erc20 protocol, we can see these basic data such as transfer transactions. But for users, if they query the data of the blockchain, if the browser does not have a special display, they can only see the hash. In the possible demand, there will be many types of data on the blockchain. These data…
