Go Ethereum (geth) is a software for Ethereum. geth doesn't provide secure networking and it should do this, as this kind of built-in functionality would increase complexity and add attack surface to critical blockchain node software. Fortunately, in UNIX world, you can easily combine different tools to work together. The solution to this particular problem is to use VPN/tunneling software for secure connections. The tunnel will expose the server local connections to your own computer. The most popular tool for this (available in every OS by default, nowadays including Windows) is [Secure Shell (SSH)][1].

Note this question only addresses issues how to

[If you are not familiar with SSH please first read SSH tutorial how to safely do passwordless logins using SSH keys][2].

Start a node on server. When the node starts it binds its RPC port to localhost (127.0.0.1 in IPv4, ::1 in IPv6). This is so-called loopback connection that you can only access from the computer itself and not from external netwo

Note: Some of these shortcuts have been remapped for my own convenience (Preferences->Keymap). These are Mac shortcuts, just use the Windows/Linux equivalent of the Cmd/Option/Ctrl/Del keys.

Cmd + P - Search file

Cmd + Shift + O - Search everywhere

(I swapped the above two recently because I use Cmd + P to search for files most of the time).

	Q: How big is the blockchain today?
	A: 415'000 blocks, 70 Gigabytes.

	Q: Where is the blockchain stored?
	A: On all the nodes participating in the Bitcoin p2p network.
	Implicit consensus is achieved by all nodes following the same rules (and incentives).

	Q: What kind of encryption is Bitcoin using?
	A: none (rather hashing and signing).
