[英]How to verify that a transaction hash is included in a block's transactionsRoot on chain?

I am doing some research to see how you would verify that a transaction hash is included in the transactionsRoot for a specific block in Ethereum.我正在做一些研究，看看你将如何验证交易哈希是否包含在以太坊中特定区块的 transactionsRoot 中。 The challenging part for this is that I am trying to do this on chain.具有挑战性的部分是我试图在链上做到这一点。

Can anyone help me figure out what data I would need to pass into a function and how I would verify this?谁能帮我弄清楚我需要将哪些数据传递给函数以及如何验证这一点？ It seems like it would be much more complicated than just passing in a merkle root and proofs since the transactionsRoot is a merkle patricia trie.由于 transactionsRoot 是 merkle patricia trie，因此它似乎比仅传递 merkle root 和证明要复杂得多。
