Checkpoint Index#
• Scott Piriou introduced Checkpoint, an indexing tool that can save events to a database and provide external queries through a Graphql API.
• Events refer to pieces of code placed in smart contracts for interaction and storage with the external world.
• Using Checkpoint is easy, requiring only the configuration file, Graphql schema definition, and Writer logic definition.
• Scott demonstrated Checkpoint using an ERC20 token transfer.
• Through Checkpoint, users can view their sent and received ERC20 tokens through Etherscan.
• Checkpoint is written in JavaScript and supports features like custom email notification systems.
• Checkpoint effectively supports fast and modular event indexing.
Chainlink Oracle#
• ChainLink and StarkWare announced a formal partnership to accelerate the goals of the StarkWare ecosystem, including the ability for ChainLink to be used on StarkWare.
• ChainLink is a middleware solution that solves the Oracle problem and helps users in various industries achieve a total transaction value of 7 trillion.
• StarkWare has joined ChainLink's Scale program, providing valuable services for developers in the future.
• ChainLink's integration helps smart contracts access off-chain data or computational capabilities for advanced applications.
StarkNet Smart Contracts#
- The purpose of this discussion is to identify the smart contract language of StarkNet.
- An important aspect of developer mode is the ability to quickly find experts to solve problems.
- Milan has done a lot of coaching work on StarkNet when mentioning the community.
- He found that StarkNet attracted highly intelligent individuals who quickly learned, and he is also learning.
- Additionally, when developers need to solve problems, tools and templates can provide a basic development experience.
- Cairo is respected in the StarkNet ecosystem for its unique features as a filter.
- Developers who choose StarkNet are more determined and can provide a better overall development experience.
rabbit X Order Book DEX#
- The motivation for regular traders and market makers is to improve price efficiency.
- The definition of an order book: storing two lists of buy and sell orders sorted by price.
- Using an automated market maker to replace the order book solves the expensive cost issue on the blockchain.
- The role of an automated market maker is to enable everyone to trade with the exchange and provide feedback to determine prices.
- Establish an irreplaceable isolation layer that does not require expensive gas fees and provides fast order matching results.
- StarkWare may help improve these issues, making on-chain order books more cost-effective and practical.
