Where can one actually buy some? I have some BTC/LTC I'd like to trade for stellar but it seems all of the reputable exchanges that trade it are closed to new registrants. Any suggestions?

I'm not a financial advisor but you can get them on Binance.

If you look at the market tab of this site, it gives you an idea of current and old exchanges for that instrument.

BTC/ETH can also be traded on Stellar's Distributed Exchange. One of the easier to use exchanges that provides a bridge for this is Stronghold.co (US/SFO based)

When Stellar's codebase was still just a fork of Ripple (entire codebase was completely re-written from scratch in 2015), it experienced many divergent forks of the network due to weaknesses in the Ripple consensus protocol. Those weaknesses have been eliminated in the new SCP described in this paper, but AFAIK Ripple still has these systemic problems. The new Stellar codebase is actually a joy to work with.

Can Stellars be mined? I received some before 2015 when they were giving it away for free. Now I'm happy that I can turn them into BTC and withdraw cash...

Stronghold[0] works great with me.

I was curious about how this was different from Ripple's approach, I thought this was interesting: > Generally, membership in Byzantine agreement systems is set by a central authority or closed negotiation. Prior attempts to decentralize admission have given up some of the benefits. One approach, taken by Ripple, is to publish a “starter” membership list that participants can edit for themselves, hoping people’s edit…

"... gives maximum freedom ..." nice way of putting the fact that there's basically no consensus; i've got even better idea, with more freedom - everybody can write whatever they want into append only database and they have freedom to choose which bits make sense.

Multiple commenters here are saying that Stellar has no consensus. Is that true? How could such a big issue be overlooked?

There’s a great, three year old HN thread about the Stellar protocol, starting with a critique by Gregory Maxwell ( nullc ) here: https://news.ycombinator.com/item?id=9342348

I’m not sure that post is about SCP? “Three years old” predates the publication of this protocol.

Trading into a very thin market there, though.

That sounds like secure scuttlebutt.

Secure Scuttlebutt is a database protocol for unforgeable append-only message feeds.

"Unforgeable" means that only the owner of a feed can update that feed, as enforced by digital signing (see Security properties). This property makes Secure Scuttlebutt useful for peer-to-peer applications. Secure Scuttlebutt also makes it easy to encrypt messages.

> Is that true?

No.

If you’re worried about it, read the linked paper. The mechanics (and assumptions) are covered in painstaking detail.
