Validating Cosmos Hub blockchain from the first possible height

[wLRy]

I am attempting to validate the cosmoshub-4 chain starting from the first possible height, which according to Cosmos Hub Summary is 5200791. So, following this tutorial, I downloaded and initiated gaia-4.2.1. Also downloaded the genesis from https://raw.githubusercontent.com/cosmos/mainnet/master/genesis/genesis.cosmoshub-4.json.gz and the ~/.gaia/config/addrbook.json from https://quicksync.io/addrbook.cosmos.json. About the last part I expected that there will be some seed peers hardcoded, but seems not. I also enabled the API in the configuration.

Finally I start gaia with

gaiad start --x-crisis-skip-assert-invariants

For over 2 hours I get messages like these in log:

And I get no blocks, as reported by http://localhost:1317/blocks/latest:

{"block_id":{"hash":"","parts":{"total":0,"hash":""}},"block":null}

What am I doing wrong?

Hi @wLRy I suspect that the nodes that you connected to have pruned those blocks. Will check to see if there are others.

Thanks in advance! I had a feeling that might be the case too. Maybe they even blacklisted me, which could explain why I keep getting those 'i/o timeout' errors?
