I've been trying to learn about smart contracts and attempting to work through a few examples. Specifically, I found this one about creating an Oracle -- https://github.com/axic/tinyoracle. The instructions specify to start an RPC server using the command
geth --rpc --rpcaddr "127.0.0.1" --rpcport "8545" --unlock 0
I notice that this produced a lot of output, including lines like below
WARN [06-14|15:17:56] Synchronisation failed, retrying err="block download canceled (requested)" WARN [06-14|15:18:19] Synchronisation failed, retrying err="block download canceled (requested)" INFO [06-14|15:19:18] Imported new block headers count=192 elapsed=969.455ms number=192 hash=5221b7…6c6c14 ignored=0 INFO [06-14|15:19:18] Imported new block receipts count=192 elapsed=1.612ms number=192 hash=5221b7…6c6c14 size=768.00B ignored=0 INFO [06-14|15:19:20] Imported new block headers count=192 elapsed=26.918ms number=384 hash=5377ec…85cf44 ignored=0 INFO [06-14|15:19:20] Imported new block receipts count=192 elapsed=1.504ms number=384 hash=5377ec…85cf44 size=768.00B ignored=0 INFO [06-14|15:19:21] Imported new block headers count=192 elapsed=27.780ms number=576 hash=28e01b…6ebada ignored=0
This seems to keep going. I eventually interrupted the process. I'm not 100% sure on what's happening but it looks like an Ethereum node is getting downloaded to my local machine. Is there a way to run a Geth RPC server without downloading an entire node?
