demo/run-validator.sh by rus-alex · Pull Request #494 · Fantom-foundation/go-opera

rus-alex · 2023-08-01T16:56:44Z

Command demo/run-validator.sh $n runs additional opera node and makes it a validator.
This may be useful for testing of go-opera releases.
Some ./cmd/opera/launcher/ refactoring is for starting fakenet validator node which is not a member of genesis validators list.

It seems that restarting the node in validator mode is still required here, isn't it?

No, it works ok without restart. New validator node starts to emit right from the next epoch.

@rus-alex @hadv @uprendis
is it possible:

to start several fakenet nodes by start.sh

then do export genesis genesisfile.g

start a new node with --genesis genesisfile.g (and without --fakenet flag)

and make it a validator as in the instructions here (need to send some ftm from one of the fake validator nodes to new account for staking)
?

why doesn't this work?

@xdfdm , it works for me. Share full commands with outputs you did to find a mistake.

@rus-alex

run 3 fake nodes:
cd demo
./start.sh

stop it. and export genesis
./stop.sh
../build/demo_opera --datadir opera0.datadir export genesis genesis.g

if check epoch and block
./opera --datadir ../demo/opera0.datadir --exec admin.nodeInfo.protocols attach
you can see that the blocks are no longer added. Everything is stucked.
