以太坊上基于UTXO模型的转账交易方案——使用手册 文档中图片不显示
1.3节中Token、UTXOTx、Vault三种关系图，展示不成功

Start with the user manual section 1.3 for the Ethereum UTXO transfer scheme and inspect the Token, UTXOTx, and Vault relationship diagram references. Check the referenced image paths or assets and preview the documentation locally. Done means all three diagrams render correctly in the published documentation.
