EIP-1559:为什么geth需要types.txdata的输入列表？

Question

我手动地合成、签名和序列化了以下原始事务：

02f87282053980018504a817c800825208940c512b60531e2440edbee50f48bafdc6d291d8dd890246ddf9797668000080c080a075488ef7d2d6192758545f0020dd3e381a610068e6e7539860461ca25a952d38a0377b07f01be37bc1ebb48eb1ec9fa62c8e4ebf5c6b03d31a113b964b8c9e37e9

它是一个类型-2事务，由类型前缀字节和RLP编码和签名的事务组成，如EIP-1559所示。

但是，将它发送给Geth会导致以下错误：

eth.sendRawTransaction("0x02f87282053980018504a817c800825208940c512b60531e2440edbee50f48bafdc6d291d8dd890246ddf9797668000080c080a075488ef7d2d6192758545f0020dd3e381a610068e6e7539860461ca25a952d38a0377b07f01be37bc1ebb48eb1ec9fa62c8e4ebf5c6b03d31a113b964b8c9e37e9")
Error: rlp: expected input list for types.txdata
    at web3.js:6347:37(47)
    at web3.js:5081:62(37)
    at <eval>:1:23(4)

事务是一个简单的值传输，没有任何调用数据或任何访问列表。然而，它似乎期待某种类型的清单。我的RLP译码器能够按以下方式读取事务：

Eth::Tx.decode "02f87282053980018504a817c800825208940c512b60531e2440edbee50f48bafdc6d291d8dd890246ddf9797668000080c080a075488ef7d2d6192758545f0020dd3e381a610068e6e7539860461ca25a952d38a0377b07f01be37bc1ebb48eb1ec9fa62c8e4ebf5c6b03d31a113b964b8c9e37e9"
=> #<Eth::Tx::Eip1559:0x000056001ab1ab00
 @access_list=[],

 @gas_limit=21000,
 @max_fee_per_gas=20000000000,
 @max_priority_fee_per_gas=1,

 @signature_s="377b07f01be37bc1ebb48eb1ec9fa62c8e4ebf5c6b03d31a113b964b8c9e37e9",
 @signature_y_parity=0,
 @signer_nonce=0,
 @type=2>

但是geth没能破解交易。因此，我假设在事务编写器或rlp编码器中存在一个bug。但我真的看不见。下列事务解码器也失败：

• https://live.blockcypher.com/eth/decodetx/
• https://www.ethereumdecoder.com/
• https://flightwallet.github.io/decode-eth-tx/

这就是我手动解码的内容：

02                           # eip-1559 transaction tpye
f872                         # rlp-prefix (list of 12?)
     82 0539                 # chain id (1337)
     80                      # nonce (0)
        01                   # priority fee (1)
     85 04a817c800           # max fee (20 gwei)
     82 5208                 # gas limit (21_000)
     94 0c512b60531e2440edbee50f48bafdc6d291d8dd # destination
     89 0246ddf97976680000   # amount (42 ether)
     80                      # data (empty "")
     c0                      # access list (empty [])
     80                      # y-parity (0)
     a0 75488ef7d2d6192758545f0020dd3e381a610068e6e7539860461ca25a952d38 # r

窃听器在哪里？一个空的访问列表应该是80还是c0？

可能是相关的：如何编码空事务字段？

好的，手动调试RLP一个小时后，结果发现我运行的Geth版本还不支持EIP-1559。*面部表情：

升级到1.10.15版本修复了它。

当签名的原始tx无效时，会发生错误rlp: expected input list for types.txdata。如果您将tx十六进制放入Ethereum解码器，它将是无效的。

在这种情况下，EIP-1559费用参数maxFeePerGas和maxPriorityFeePerGas不受支持.通过用gas和gasPrice替换它们来修正。
