Anyone else getting private messages promoting BU? Looks like Ver updated to the astroturfing premium package.

Miner signaling for blocks larger than 1MB is now at 48%, are you still so sure SegWit is not a trojan horse from a bankers backed private company, trying to squeeze in their own code at any costs?

Yes, fuck off please. Who even takes an astroturfing job like that?

Multisig wallet transfer, security implications of signer giving their phrase to someone else

Normally, giving out a phrase to recreate your wallet is a bad idea.

If I have a multisig wallet – lets say 2 of 3 – and don’t want to participate as a signer anymore, I think I can give the phrase to recreate my wallet to someone else.

Even if we would both be in possession of that phrase – assuming there is no way to trustlessly do this – it seems that moving funds would still require the other signers in the p2SH script.

The only possible downside is if I retained access to the wallet and rejected signing transactions, that the new owner of my key would have accepted.

What are your thoughts? Am I missing something

Running a Bitcoin node (behind Firewall / NAT or anything else? disallowing inbound connections)

I consider running a bitcoin full node on a raspberry Pi 3. I want to attach the raspberry Pi into my home-network (wifi). When I check my IP address I have a public address to the outside (which is changing from time to time, however is only one of 5 different addresses) and via NAT given by my ISP. I don’t know what is between “my” public IP and my homenetwork in detail.

As I understand it correctly a bitcoin node does only good to the overall network iff it can accept inbound connections, therefore my raspberry pi must be publicly available (behind all this NAT whatever). If I run a bitcoin node I would like to use it at least by myself as a trusted node inside my mobile bitcoin wallet…

In the end I see two ways to do that:

  • Resolve NAT issues with one of the following techniques: Upnp, TURN, NAT hole punching, STUN, ICE, IGDP, NAT-PMP, PCP, ALG, wathever else there, I don’t know…
  • Or running a hidden service.

So my question:

  • Is it good/bad/ok to “only” allow inbound connections as a tor hidden service?
  • Is there an easy way to get a bitcoin node with “traditional” means available as a public node inside a home network?
