devp2p ，Does it support BSC networks?

[myuniswap2000]

hello, amin, everyone!
1,devp2p ，Does it support BSC networks?
2, I run /packages/devp2p/examples/peer-communication.ts:
node -r ts-node/register ./examples/peer-communication.ts:
but, it is error:
Peer error1 (18.176.58.248:30311): Genesis block mismatch: d4e56740f876aef8c010b86a40d5f56745a118d0906a34e69aec8c0db1cb8fa3 / 0d21840abff46b96c84b2ac9e10e4f5cdaeb5693cb665db62a2f3b02d2d57b5b

3,i add bsc conf is : import bsc.json
const common = new Common({ chain: bsc });

4, thank you !!

I know @srgl was able to get it working (see comments in this issue. We don't actively support BSC but it looks like it should work based on this previous issue. @srgl, any chance you could share the common configuration you used to get BSC working?

Also replace checkblock parameters in peer-communication.ts according to bsc chain.

hi，@ thank you for hlep me!
(1)i conf is like @srgl .
(2)but, run peer-communication.ts:
i have many erro is :
DPT error: Error: Peer is banned
DPT error: Error: Peer is banned
(3)and have not receive TX!
please help me!

[srgl]

You can ignore peer ban errors. What TX are you trying to receive?

[myuniswap2000]

in addition,
Do I need to configure "genesisStates" ?

[myuniswap2000]

I need to receive new block and tx

[myuniswap2000]

i have not find checkblock param ...

[srgl]

You need to correct these lines according to the bsc:

Sorry, I do not have a code, but you can use any block number/hash from the chain.

1,
ok, thank you very much!
2,
Has the data message of BSC changed? Do you have relevant information about the code I want to modify? I'm not proficient in geth. thank you

[myuniswap2000]

I succeeded. I got TX. Thank you very much for your help. I wish you have a nice day!
💯 🥇 👍

[bpbogdanpop]

@srgl @myuniswap2000 I'm still not sure what should I use for CHECK_BLOCK_HEADER? I already took the number and hash of a block from BSC. But where do I get that CHECK_BLOCK_HEADER Buffer hex string from?

@bpbogdanpop That is the block RLP for the Berlin hardfork block (as an example). If you want to replace it with another block, you can request it from the peer and console.log their payload output (with toString('hex') on the buffer to get a nice copy and paste value), and replace it.
