I have serveral geth-core running on different regions cloud-server, one running on my local computer.
I don't know why my geth-core(local computer) can't keep up the newest block , it always delay about 10w block. but my geth-core on cloud-server is sync the newest block.
Sometime i want to send a transaction from my local computer , it will return the tips about balance not enought (the balance had not sync to the newest block ).
So, how can i broadcast the transaction by my other cloud-server using json-rpc ? i don't want to send my keystore to my cloud-server .
