If we only intend to send a transaction to Ethereum blockchain, do we need to be "full node" to have the entire blockchain? meaning that do we need to be "sync" with the blockchain to have the latest block?
Apparently when I send a transaction using Parity my transaction in not mined till I become "sync". I'm wrong? Or maybe just I need to be connected to some node whether I'm sync or not.
To send a transaction to the network, all you need is a connection to it.
When using geth or parity, your the nodes may not broadcast your transactions until they are reasonably close to being fully synced with the network on some modes.
You can always run them in a light mode setting, which allows them to connect to already synced nodes and make requests, or in a fast/warp sync, which takes a lot less time to complete than a full sync.
Alternatively, you could use an API provider such as etherscan or infura to push a raw transaction out, and not run a node at all.
