What is this for?

lbenevento commented 2 years ago

web3.exceptions.ExtraDataLengthError: The field extraData is 97 bytes, but should be 32. It is quite likely that you are connected to a POA chain. Refer to http://web3py.readthedocs.io/en/stable/middleware.html#geth-style-proof-of-authority for more details. The full extraData is: HexBytes('0x696e667572612e696f000000000000000000000000000000000000000000000025554ffcf985fe8bfbd390015fb479713c85822594e2247bc1b631af6126a1d9765b176fd01ef33a66d11fd09e8ea40e327ba942fe6855f18dc57d14a44a330000')

Without that we get this error. As far as I understood it depends on a discrepancy in PoA standards. Here is some info: https://web3py.readthedocs.io/en/stable/middleware.html#why-is-geth-poa-middleware-necessary

Interesting... is this an error from kovan? I'm not sure anyone else is getting this... Thanks for the PR... Maybe we make it an optional comment?

It's not from Kovan, I'm using the rinkeby.infura.io/v3 https api. As I previously said I'm no expert at all so if you think making it a comment is the way to go I can just change the pull request to specify which error these two lines are supposed to fix!
