## blockchain data engineering toolkit
### chapters
* **[token-scanner-api](token-scanner-api)**:
- a mvp for a **scalable event scanner cli and api for ethereum**, through indexing and parsing blocks events. this is the first step for training **machine learning models on the chains** (e.g., high-frequency trading with deep learning)
- check my mirror post **[on building a scalable event scanner for ethereum](https://mirror.xyz/go-outside.eth/vSF18xcLyfXLIWwxjreRa3I_XskwgnjSc6pScegNJWI)**
* **[implementation of a draft of an EIP for rental NFTs with rights management](eip-9999)**:
- this standard is an extension of ERC-721 and ERC-4907
- it proposes an API for rights management through a rental license
- this framework is fully compatible with the licensing framework proposed on ERC-5218, although it can be implemented independently
* **[a protocol for management and bartering of game (NFT) assets](game-protocol-design)**:
- discussion, design, and implementation route of a protocol for management and bartering of game (NFT) assets
* **research notes**:
- **[rlp encoding](technologies/rlp_enconding.md)**
