Ropsten testnet PoW chain

Join the chat at https://gitter.im/ethereum/ropsten

To resync to the revived Ropsten chain, at the command line run:

geth --testnet removedb
geth --testnet --fast --bootnodes "enode://6332792c4a00e3e4ee0926ed89e0d27ef985424d97b6a45bf0f23e51f0dcb5e66[email protected]52.232.243.152:30303,enode://94c15d1b9e2fe7ce56e458b9a3b672ef11894ddedd0c6f247e0f1d3487f52b662[email protected]192.81.208.223:30303"

or for Parity:

parity db kill --chain ropsten
parity --chain ropsten --bootnodes "enode://6332792c4a00e3e4ee0926ed89e0d27ef985424d97b6a45bf0f23e51f0dcb5e66[email protected]52.232.243.152:30303,enode://94c15d1b9e2fe7ce56e458b9a3b672ef11894ddedd0c6f247e0f1d3487f52b662[email protected]192.81.208.223:30303"

or for cpp-ethereum:

eth --ropsten --kill --pin --peerset "required:6332792c4a00e3e4ee0926ed89e0d27ef985424d97b6a45bf0f23e51f0dcb5e66[email protected]52.232.243.152:30303 required:94c15d1b9e2fe7ce56e458b9a3b672ef11894ddedd0c6f247e0f1d3487f52b662[email protected]192.81.208.223:30303"

Troubleshooting

If you have problems syncing to the right chain, you can force your client to connect strictly to peers known to be on the revived chain. This only needs to be done for the initial sync.

For geth, start the client without connecting to any peers:

geth --testnet --fast --nodiscover

Then in the console (geth attach), add them manually:

admin.addPeer('enode://94c15d1b9e2fe7ce56e458b9a3b672ef11894ddedd0c6f247e0f1d3487f52b662[email protected]192.81.208.223:30303')
admin.addPeer('enode://6332792c4a00e3e4ee0926ed89e0d27ef985424d97b6a45bf0f23e51f0dcb5e66[email protected]52.232.243.152:30303')

For parity:

echo -e "enode://6332792c4a00e3e4ee0926ed89e0d27ef985424d97b6a45bf0f23e51f0dcb5e66[email protected]52.232.243.152:30303\nenode://94c15d1b9e2fe7ce56e458b9a3b672ef11894ddedd0c6f247e0f1d3487f52b662[email protected]192.81.208.223:30303" >> ropstenpeers.txt

to add the peers (one per line) to a text file, and then run the client with flags:

parity --chain ropsten --reserved-peers ropstenpeers.txt

You can check that the client is on the revived chain by comparing to the block numbers on http://ropsten.etherscan.io.
