| Scrapling | union | |
|---|---|---|
| Summary | Scrapling is a Python web scraping framework whose parser can "adaptively" relocate elements when a site's HTML changes, paired with stealth fetchers that bypass anti-bot systems like Cloudflare Turnstile and a Scrapy-style spider engine for concurrent, resumable, proxy-rotating crawls. | Union is a trust-minimized, zero-knowledge interoperability protocol for general message passing, asset transfers, NFTs, and cross-chain communication between blockchains. It is built in Rust without relying on trusted third parties, oracles, or multisigs, instead using consensus verification and ZK proofs. |
