listen to this bullshit Karen Gifford of Ripple Labs spews forth to the Calif Assembly @14:00.
Chris Larson also says he doesn't believe we need a new currency:

https://clyp.it/zdpzphmd

Ripple is the enemy.
Does David Schwartz still hangs out on this forum?


Yup: https://bitcointalksearch.org/user/joelkatz-27870



The last time I talked to him was at the 2013 San Jose conference.


Me too. At the Ripple booth.



I wonder if he knew back then he was going to sell out.

Interesting question. Ripple's outward marketing language flip flops quite a bit:

2013: "We do not intend for XRP to be a valuable currency" (I forget where this was noted; probably in all the discussion around the launch)
2014: "We do intend for XRP to be a valuable currency" (language from their website, iirc, said as much)
2015: "We do not think the world needs more currencies" (Chris Larson, to CA regulators)

But whatever. Once people figure out that Ripple is just a linear advance in database tech, and that database-instance-agreement in trusted environments is possible in cleaner ways (tokenless ledgers; eg, hyperledger), it may not matter what Ripple says about XRP.

In terms of economic incentives toward SC bleeding value out of MC, which appears to be a major misgiving with SCs; it has already happened with alts less so now (but I think it will accelerate again when a bull phase returns) and also with counterparty, mastercoin and bitshares that are in essence one-way pegged assets.

So we already have it in the protocol to create 1-way pegs, you can't stop that and they have shown how they siphon value out of the main chain, e.g. mastercoin has been many multiples of its btc 'cost' at times. In all probability, making a 2-way peg facility available that makes it more efficient to go in and out of the MC makes it less likely than it currently is for value in total to exit the MC via super successful 1-way pegged assets. Therefore in that analysis, as the protocol currently exists it is more vulnerable than one allowing for 2-way pegs. You could consider it as the 2-way peg closing the economic value loophole for an attack with very successful 1-way pegged assets ... shhhhh. After a successful soft-fork allowing for 2-way pegged assets any entity proposing 1-way pegged assets will be viewed skeptically and economically disadvantaged by the market perception of losing interoperability with the MC. The market will prefer 2-way pegged assets over 1-way pegged every time, and that is a net benefit to the total value proposition of bitcoin surely.

That is an interesting way to look at it, thanks

Absolutely true. Value is a "nominalization" to borrow a term from NLP: http://youtu.be/1sceRsmT1yc


Good vid thanks. Feel like I could have wrote much of that myself! but Worth has lucidly expounded and expanded on it thoroughly ... and it is a much needed topic that people need to learn about, kudos.

Edit: here's another great, clear vid re: What is Bitcoin wonder if these have made it on top r/Bitcoin yet?


Thanks! To my knowledge, none of my videos have made it to /r/Bitcoin - I'm not very good at self-promotion, unfortunately.

There is no loss of "interoperability" as long as exchanges (centralized or otherwise) exist. Non-pegged alts have floating value, but they aren't unconvertible currencies. Those are two different concepts.

It remains to be seen whether the friction of conversion is preferable to the friction of pegging, but isn't clear in the abstract.

1 way pegged alts also have exchange values facilitating interoperability.  i don't see any loss for Bitcoin to these.  in fact, i see the opposite:

Disregarding completely any motives (real or imagined) behind people implementing SC consider the following (which i haven't seen elsewhere).

In terms of economic incentives toward SC bleeding value out of MC, which appears to be a major misgiving with SCs; it has already happened with alts less so now (but I think it will accelerate again when a bull phase returns) and also with counterparty, mastercoin and bitshares that are in essence one-way pegged assets.

Here's another way to think of bitcoin, and sidechains. Picture that bitcoins are like digital real estate and you can already add features to your plot of real estate; create coloured coins, burn them (lock irretrievably) to prove mastercoin/counterparty ownership, multisig, smart scripting conditions, etc. People are already building things on their bitcoin plots that increase the value of their own piece, but also the whole value. A sidechain is just another "building project" that is anticipated to increase the value of their piece of sand, and most likely everyone elses.
https://docs.google.com/presentation/d/1Tc_fhTPqbdlvApnWQWsgzG1U6NwN9lgkQsTdm5O-9iA/edit#slide=id.g6eb72e55c_0395
see slide 15-19 specifically.


i just referenced that talk above.

i have a real problem with slide 19 that shows "reversion" or getting your BTC back from the scBTC.  as i said above, during a 51% SC attack, the last thing the attacker (miner) will do is include your proof of lock in a block to let you off the SC.  he either wants to steal the scBTC or destroy them.  most likely the latter, b/c the mere happenstance of the attack will likely destroy all exchange value of scBTC.

Without knowing the specific mechanics of the peg it is meaningless to discuss whether or not the reversion would be successful in the case of mining (or other) attacks. E.g. there might be a timelock on the whole sidechain, so that it is like a 10 year or 99 year leasehold arrangement. There are many ways this could go, dismissing SC outright is denying experimenting and innovation that could solve some of bitcoins problems in tangential ways, even if sidechains are never a success. To me, getting militant against SC seems a bit like the goldbuggery with respect to bitcoins being able to have value as a monetary unit. Keeping an open mind can pay huge dividends, dangers and risks can be mitigated when they are apparent, knowable and quantified.

fair enough.  but the flipside is also true; holding out unrealistic promises & capabilities should not be used as an excuse to block or derail much needed MC development that may in fact be more ideal.  it never hurts to discuss these concepts.

absolutely, e.g; a chunk of MC dev work is currently being funded by a sidechain research company Wink, and appears to be the only company funding core infrastructure of MC with a long term view (besides Bitpay's jgarzik) and stated commitments to open, permissionless platforms for innovation, in fact, that is their view of what SC will also allow to stop the energy bleed into alts.

this makes an interesting listen in retrospect (also before Blockstream was announced or fully gestated i expect)
https://letstalkbitcoin.com/e99-sidechain-innovation/

well, once again, it's all in the eye of the beholder.

in that LTB interview, Adam talks about altcoin dilution of Bitcoin. while true at the time, i believe it has become much less so.  many are dying out in this bear mkt w/o SC's and that is good for Bitcoin. 

also, i don't see Gavin going anywhere despite whatever happens to TBF and he confirms this here:  https://www.reddit.com/r/Bitcoin/comments/31rgtb/when_the_foundation_shuts_down_who_pays_gavin/cq4cqq5  and i'd bet this applies to Wladimir as well.  being a Bitcoin core dev is a coveted position whether you're formally paid or not.

if Blockstream weren't a for profit entity that has openly stated a desire to create all sorts of SC's, even for gvt currencies, based on a needed source code change then i might understand the concept.  but that's not how it is.  and no one can accuse me of being an altcoin proponent as an excuse for my objections.

and as far as premature discussions are concerned, it's not like we don't know about the majority of what will be be presented.  i mean, Adam was here in this very thread openly discussing all their plans for like a month and a half?  we know alot about the concepts involved.  why not debate them?

that's not at all what is happening.  BTC deposited on an exchange are parked in an address owned by the exchange.  all the trading is just on its own internal DB.  when an owner wants to withdraw from the exchange, it simply draws from the pooled address and sends back to the owner's personal address.  none of the BTC has EVER left the blockchain.


BTC deposited on an sidechain are parked in an address owned by the sidechain, all the trading is just on its own public side-blockchain.  when an owner wants to withdraw from the sidechain, it simply draws from the pooled address and sends back to the owner's personal address.  none of the BTC has EVER left the blockchain.


You're neglecting the friction I mentioned above. Also, when mtgox blows up, "someone" has  those coin. When a SC blows,  those coins will be gone.

Let me also introduce  another concept that represents my assessment of what will occur. Miners will not support SC's because ultimately SC's will be an unknown risk to their business model. They won't support that uncertainty. That's just my opinion.

You can withdraw from mtGox only if Karpeles allow it. You can withdraw from SC if you can create proof that you own pKey in SC.  It is human's will vs proof of math.

SC does not need a lot of miners. SC can timestamp transactions(whole side-blockchain) in bitcoin blockchain. (Same as CP does)

SC's require ideally 100% of current Bitcoin miners to MM to equal the security of the MC itself.  anything less represents a security vulnerability.  SC's are also based on POW (at least the spvp model is which is what i'm talking about)

I don't think the "security" is "equal" even with 100% merge mining. Yes the hash rate is equal which makes it equally secure against the specific case of a pure outside hash rate attack. But the fact remains that at any time those MC miners can decide to stop merged mining at little to no cost to themselves, making the merge mined coin insecure. If I'm an attacker the first thing I do is give a bribe to pools to stop their merged mining, and it won't take a lot because they're not making much/anything on the merge mining to begin with. Perhaps this can even be done in an anonymous trustless manner with some sort of smart contract (seems likely if scripts allow SPV proofs)

An article about applepay, not specially interesting, but I noticed this:

Unlike the consumer electronics business where Apple regularly rolls out new computers or phones in dozens of countries at once, there is no such thing as a unified payments market.

Each country is inhabited by often warring banks, credit card associations, telecom operators and retailers, while payment preferences and regulatory regimes can vary widely.

"Every market will have different local players, different partnerships, different local standards, different economics, different levels of cooperation," said Morgan Stanley technology analyst Andrew Humphrey.


...while wondering, with a twinkle in my eye, who can change this?

now that the concept of the Bitcoin unit being inextricably linked to the blockchain is finally being better understood, the next logical extension of that concept is that sidechains make no sense.  for all of the reasons i, and Adrian, have been arguing for months on end late last year.

No, its a well known logic axiom that the positive does not imply the contrapositive.

In other words, yes, the blockchain needs the bitcoin token.  But that does not imply that Bitcoin needs the blockchain.  Ok, ok, Bitcoin obviously needs the Bitcoin Blockchain to exist as it contains the history of the token's value appreciation and forms the foundation of its awesome features.  So what we are really asking is "does Bitcoin need to use the blockchain exclusively?"

Well can Bitcoins be traded off chain?  Of course.  Judging by exchange volumes it seems that most transfers (trades) already occur off chain.

A sidechain is just a decentralized way to make off-chain transfers.  Judging by what's going on on exchanges, if sidechains work they'll be popular even if their sole use is to decentralize some of the currently-existing centralized solutions (changetip?).

I think that there are very limited uses for a blockchain without an independently valued token (i.e. not a fiat representation token).  I have discussed some in this thread.  But in the ultimate egg-on-face for all the naysayers, I think we'll discover countless uses for a digital value token (aka bitcoin) and our ability to deploy crypto-currencies into these applications will actually be hindered by the inconvenience of the blockchain.  Sidechains (if they end up viable) are an attempt to reduce this inconvenience by opening up development of the blockchain, but keeping the token.



The Bitcoin token is a mental shortcut we use to manage the money is memory idea. What I'm saying is your Bitcoin private keys are the tools you use to control a percent of the Bitcoin blockchain. How many Bitcoin you own is common way of saying I manage X% of the value ledger (the total potential of Bitcoin blockchain) . Bitcoin wouldn't need bitcoin tokens, if there was another way to manage your % of the blockchain. And miners wouldn't need to mine bitcoin if they could mine direct control of a small % of the blockchain with every block reward.

You are making the mistake that the token has value, no the value of the token is that it represents the Bitcoin Blockchain, if you want Bitcoin to be the biggest value ledger you have to use it. Trusting your private keys to be managed by SPV proof in the Bitcoin protocol so you can move value over to another token, is abandoning Bitcoin, the risk this poses to Bitcoin is the economic majority may choose a sidechain over Bitcoin blockchai with different (improved by there reckoning) economic rules.

I for one would rather they had just one option and that is to transfer value using the Bitcoin blockchain.

the "proof of lock" needed to exit the SC requires that it be mined and presented back to the spvp.  if the SC is being 51% attacked, then this won't happen and your scBTC will be stuck on the SC and therefore your locked up BTC on the MC will never be unlocked.

BTC "locked" into a sidechain also do not ever leave the blockchain.

no, they're being passed thru the peg to a new blockchain, the SC, which is less secure and thus fundamentally different than the MC.

SC's present its own form of problematic deposit; the spvp.  talk about friction; it will be necessary to have at minimum a 2d proof of locktime, probably more.  and then in the federated server model according to Adam himself, a necessary bounty to prevent cheating by the centralized owners.

...

it is all pie in the sky and glosses over the potential for losing coins while stuck on the SC in case of an attack.  these SC's will be attacked as they will be insecure by virtue of the fact they won't have 100% MM.  and there is just no guarantee of one getting his coins back on the MC in that event as their simplistic SC sandbox in the Bitcoin Park diagram is suggesting.  those miners who were once MM'ing to protect the SC can turn around and perform a 51% attack on the SC and refuse to mine the "proof of lock" thus disabling a return of those BTC all the while going short on the SC at an exchange. the slideshow presents as if nothing can go wrong.

There will be different security models for different use cases. Are there potential security threats? Of course, I think we've all come to an agreemeent that there are no such thing as a risk free extension of Bitcoin. Luckily there's a whole team of very smart people working to understand how these can be best mitigated.

That said, your premise : "the next logical extension ... that sidechains make no sense", makes no sense and does not apply to the currently debated blockchain without bitcoin meme.




it does make sense.  just not to you b/c of your mental framework of how you look at it.  those who have promoted SC's, while using your argument of "never leaving the MC" for marketing, have also simultaneously complained about how what they can do with Bitcoin is being constrained by the MC.  thus, they want to "move BTC with its value" over to an unconstrained SC, and reanimate them to scBTC, via the passthrough peg.  thus, the concept is no different than what the blockchain w/o BTC proponents are arguing which is somehow that the MC can function w/o the currency units. 

one of Bitcoin's main strengths is forcing current players to play according to the rules as they are which is the MC working in concert with BTC as a self contained financial system.  this focuses all development onto the MC to maximize innovation and returns to miners and participants in the long run which is needed b/c of the transition to a tx fee economy.  anything that allows innovation to happen off the MC risks devaluing the entire Bitcoin economy.  the whitepaper already said that current Bitcoiners could be forced to migrate to a SC if it takes over which would be a disaster, imo.

i'd also argue that Bitcoin is in a perfect Nash Equilibrium at the current time.  i think we've also all agreed that SC's will be disruptive to the mining equilibrium.  anything that disrupts that equilibrium will either be ignored or attacked, imo.  hence, i doubt that SC's will get a majority of miners to MM.  i'd welcome the evidence you say that shows otherwise.

BTC "locked" into a sidechain also do not ever leave the blockchain.


What's important is where the value stored on the blockchain goes, sure the private keys controlling the Bitcoin locked in the Bitcoin blockchain secure the same percentage of the Bitcoin blockchain, but the value leaves the blockchain and moves into the sidechain, Bitcoin will be diminished.

Value is a key element in the incentive structure that makes Bitcoin. Erode it enough and the consequences could be bad.
