Tentatively climbing back up? A couple of my more adventurous limit buys didn't get filled.

I actually would regard using LN as the natural progression of scaling up peer to peer payments. Consider that much of the peer to peer traffic on the internet itself which we used to have has moved more to peer - "cloud" - peer system.
Good parallel.

Can't remember the last time I used a torrent program to get data.
... but if some data should get censored everywhere from "cloud peer" systems, it would spread through torrents like wildfire. That is, base blockchain transfers will always be an option, no matter what.

Not sure if I understood that correctly but if I did, I could view torrents being replaced by cloud services as a regression from a decentralised system back towards a more centralised one. Cloud services are provided by a small number of large companies.
You're right.

I expressed my thought clumsily. By "good parallel" I meant to make a point with those that are afraid LN means more centralization. It will also reduce costs, as peer-cloud-peer systems do: most peers don't need to keep seeding the torrent.

Anyway I still find torrents useful.
I also still use them, even if they're not that fashionable anymore. What I failed to convey is that they will still be ready to use, and back in high demand, if (when!) circumstances (censorship) will make them necessary again.

But anyway, thanks for a civilised response. I prefer reasoned debate than being told to fuck off.
Oh, well, fuck off then.

Translation of SEC concerns: "Futures as implemented now are totally inadequate since they can't manipulate the price."

At least the way I understand it.

Just to be clear,  those numbers were pulled out of a near total contextualized assessment of BTC market dynamics accounting for historical happenings, momentum and future probabilities of a variety of events that have not yet happened, including trade volume representations, knowns, unknowns and uncertainties.

In other words, I am employing a kind of amalgoratiated "speculation" within conformity of the WO tradition.     Tongue

So...from your ass?
How brutal, Arriemoller!  Roll Eyes

Thanks for the summary, Peter!

Zohar modeled the flow of coins as a random walk.  For example, if a channel starts with Alice and Bob each holding $100 dollars, and if you imagine them routing through their channel N payments of $10 each, we'd expect the channel to be fully lopsided after routing 100 transactions ( [$100 / $10]^2 ).
It might actually be even worse than that if the transactions are not independent (and I assume they aren't, at least until the salary-in-BTC is a reasonable assumption).

Quote
If recharging the channel costs $30, then fees need to be at least $30 / 100 = $0.30 per transaction per hop.  If it takes 5 hops to route your payment, that is at least $1.50 in fees.  
However, increasing the number of channels per LN node makes the average unbalance converge to a normal (Gaussian) distribution: a bell centered on zero with a standard deviation (width) that grows with average transaction size.

The number of channels can be increased with limited (ideally null) additional financial exposure by making the channels smaller - if the hypothetical transaction slicer/packetizer is in place.

Besides, you're assuming funding a channel costs 15% of the channel capacity (30$ for 200$ capacity). I don't think this is realistic, as the blockchain related funding cost should only be a function of the number of utxos under SW regime. And it would definitely be a SW transaction.

I guess we'll see.

Won't LN make payment processors like Bitpay totally obsolete? Smiley
But I think LN fees will be too high and the network too impractical to compete with on-chain payments on an uncrippled cryptocurrency.
<crystalball>
Incentives, Peter. With the entry cost of setting up a LN hub close to the simple funding of channels, my guess is there will be fierce competition on prices, some of which motivated by purely political, rather than financial, reasons (as in: I, for one, will start a hub as soon as it's practical). With such low-denominator price wars, and low ROI volunteers helping the net nearly for free (as full nodes already do today), I don't see how a high fee level could be sustained.
</crystalball>


There was a really interesting talk on "Recharging Lightning" at Scaling Bitcoin Stanford by Aviv Zohar.  You can watch it here:

https://youtu.be/3pd6xHjLbhs?t=1h2m21s

He showed that LN fees in fact wouldn't be as low as many people expect because:

- channels eventually become depleted and need to be "recharged." This costs 1 on-chain fee which needs to be amortized over the life of the channel.
That's right. That's where CoinJoin-like refunding can help. Actually, I'm not 100% positive that system has been extended to deal with refunding yet, but it can and it will. You can then plan your re-fundings in advance, and pay a fraction of the fee if you are willing to wait.

- the bigger you make the channel the longer it lasts before needing a "recharge," but then the more money you tie up.  There is an opportunity cost associated with this money tied up in a channel (modeled as an interest rate by Zohar).  

Zohar shows that the only way fees can be very very small, is if channels are very very richly funded OR if on-chain fees are also very small.  Neither of these conditions will hold however (well outside of a highly-centralized hub-and-spoke model where the hubs control all of the LN channels).
I would much prefer a written source, but I do get the gist of the model, which seems indeed sensible. I would like to see some quantitative estimates on "very very richly founded". In principle, I agree that at first it could be so that you need a mammoth channel to deal with the occasional mammoth payment (or several squirrel payments), but once a system is in place that implements a kind of "packet switching" for payments, splitting them over different channels/routes, that problem will disappear. All it takes for the system to work in a quasi-steady state is the global I/O of the channels to nearly null out, which means little fresh btc need enter/exit the LN.

Alternatively, Average Joe - who runs a LN hub whose net capacity flow is negative (more BTC going out than in) - could send fiat or other low-fee cryptos into some LN-friendly exchange, which in turn would refill Joe's channel with positive capacity. It remains to be seen how the flow will be organized, although until salaries are paid in BTC I imagine normal user channels would send more than they receive on average. The net effect for Joe would be that of "buying moar", which for an enthusiastic LN volunteer (possibly politically motivated), sounds quite desirable.

Totally obsolete, not immediately.
Until at least some of your providers in turn accept LN payments, some kind of bridge to/from fiat will still be necessary, as you need to unload your channels when their in-capacity gets filled up.

critical vulnerability in electrum?
I read up something about that. I guess those of us who use NoScript should have been fairly safe.
4213  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: January 07, 2018, 03:44:07 AM
Why would LN not work out as planned? Just out of curiosity, I'm eager to know where the BCash hope is.


I don't think the LN will work technically for two main reasons: (1) the high fees to open and close channels will make it too expensive to be practical,
There are two CoinJoin-like solutions being developed, at least one of which is at a fairly mature stage of progress, as I understand it.

and (2) there is no known solution to route-finding with a mesh topology so the network will have a hub-and-spoke topology instead.
No exact solutions in the sense of optimal, shortest-metric routing. A decent heuristic is enough to get the system going and avoid a hub-and-spoke topology. How does TOR manage to create circuits?

But let's ignore that for now and assume that LN will work like BS/Core expects.  There is still the _huge_ problem that LN is a new network and needs lots of people to adopt it in order for it to have value.  I think people think that when LN is "released" that suddenly all wallets will be able to make LN payments just like they can make bitcoin payments today.  But that's not what will happen; instead, the first people to open channels will only be able to send payments to a couple of vendors and a handful of connected people.  It will take years and years for the network infrastructure to get the point that Bitcoin was at 3 years ago.
What I'm saying now is pure speculation, but bear with me. All the users that whine about high fees should be able to put some pressure on vendors - and especially exchanges. I agree that segwit adoption is going slowly; but that's because few wallets support it. If half of the users had a segwit-enabled wallet, it would be much harder for exchanges to delay upgrading. The customers would flock to the first exchanges to adopt the new technology.

BTC is sabotaging itself.
It isn't. It's in a pupal stage IMO, preparing for the next metamorphosis.

4214  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: January 07, 2018, 01:38:54 AM
(2) Accepting BCH for payments is trivial for all the companies and payment processors that previously accepted Bitcoin but stopped due to high fees and unreliable confirmations.  BCH is a drop-in replacement where as supporting BTC is more complex due to segwit (+ further complexity should LN be viable).  
Of course accepting BCH is trivial for those who already accept bitcoin.
All BCH did is increase the block size while keeping all witness data in mined blocks.
It could be seen as sweeping a problem under the rug, or as kicking the can a few feet further down the road.

BTC is more complex due to segwit - and hopefully soon LN too - because it's evolving in order to survive the technological challenges. It's not sweat-free. No free lunch and stuff. The benefits of upgrading will be more than worth the sweat for merchants (little sweat) and users (no sweat as soon as the first user-grade wallets become available).

But why am I explaining this to you? You are a technical person, aren't you?
4215  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: January 06, 2018, 09:30:50 PM
Am I understanding it correctly that LN only works with segwit?

Why would it work only with segwit? I see no technical reason, but segwit adoption would certainly help LN to make opening/closing LN channels cheaper.

LN as it is now depends on transaction malleability being fixed. That's why it was designed with segwit as a prerequisite. So yes, Ibian, you are correct as far as the real current Lightning Network goes.

Old coins are now worth $19951USD/$24766CAD (Coinmarketcap).


ok searched a bit and i still cant figure out what this means.. what are "old coins" and why are they worth more?
Unsplit BTC still with a BCH, and possibly other forkcoins, inside.

Another yummy snippet from fluidjax.

Total ban on mining in China..
A slow orderly exit is planned - apparently confirmed by Jihan (by Cryptovenus)

https://twitter.com/cryptovenus/status/949405526315716608

The BTC market should see this in a positive way, but there is no accounting for stupidity.
The will force chinese miners to relocate and spread out geographically, and also cause them higher electricity costs, which will allow more competition.

If this is confirmed, it's quite an important piece of news.
I also see this as quite bullish. Never forget: the freedom that comes with decentralization is Bitcoin's main asset.

By the way, this appears more plausible than the customary quarterly "China bans bitcoin" FUD items. There's no FUD context (or necessity) this time, so it does look different.
4218  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: January 06, 2018, 06:35:42 PM
A major thing people forget when simply saying we need a small block size increase, is that it requires a HARD FORK.
This means that a whole bunch of people with 100,000's of Bitcoins are going to be pissed. MP & his group for one. Probably a number of others.

These people, along with many others will probably continue the existing chain, claiming it is the real Bitcoin. (Just like BClashic but much worse).
Imagine the damage that is going to do to Bitcoin, we must have  an overwhelming consensus otherwise it's going to be a clusterfuck!

Clap, clap. The blocks will get bigger when they will. Let's turn our heads to the real alternative solutions. The pot is on the fire, soon dinner's gonna be served. Let's just get the big actors to come along ASAP.

Hello, Coinbase? Hello? Anybody in there?

You ECB, stop printing all those fancy euros before you call companies that help people save themselves from inflation "crappy"!  Tongue

Seriously, most of the companies that offered cards through Wavecrest have sent out emails to customers saying they will replace the cards (free of charge) as soon as they find a viable partner. I haven't received any such email yet, but it's still the weekend.

i think it's gonna take months or maybe never before they find replacements, especially for gbp cards. wavecrest was the only game in town for a lot of them.
I'm afraid it won't be much quicker for cards in euros, either.
4220  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: January 06, 2018, 03:33:28 PM
Crypto (carding) is done.  Undecided

people with coinbase and american bitpay cards are fine. it's one crappy company being crappy. if a non crappy company shows up then the people who've lost cards will get other ones.
