I'm running geth on Ropsten, using

geth --ropsten --syncmode "light" --http.addr localhost --http.port 8545 --rpc

My most recent block number is 10266786 (and increasing), whereas etherscan.io says 10265079 and others confer something within that range of etherscan. About an hour ago, my block number was also 10266000 < n < 10267000, though etherscan and others showed somewhere in the range 10264000 < n < 10265000. I'm fairly new to ethereum. Is somebody sending malicious blocks to light nodes in the Ropsten testnet? Or is there an easy fix to this?

  • What's your geth version?

  • 1.9.25-stable -- I switched to using Infura now after writing this btw, but figure should still keep the question open in case it's relevant to others

  • Berlink fork was applied to Ropsten back in March, and you need at least geth v1.10.1. Perhaps your node is following a forked branch. That kinda explains the difference. The other explanation is that etherscan testnets sometimes breaks or isn't updated quick enough because it is a testnet.
