Is the price of BTC going down because of altscams? In fact, a successful sidescam might push BTC's value up since it would essentially increase the scarcity of the remaining coins.
Scams depress price.  Alt scams, exchange scams, pirate@40 scams, these all depress price, reduce confidence, encourage regulation, and suck wealth and productive resources out of the crypto economy.  SC scams should be expected to do likewise.

absolutely.  the "oh, my coins will only be worth more" crowd is missing this point.  especially considering that Bitcoin proponents/owners would be the ones who could get wiped out.

Then we agree.
Side chains accommodate arbitrary crypto (good bad or ugly) and which crypto is used for a particular chain matters.

It is my understanding that while the transactions can use arbitrary crypto, block hashing would be limited to sha256 (or possibly a small list of others).  In order to ensure a malicious attacker can not simply lie, the bitcoin miners supporting SPV proofs will need to verify the block hash is valid for the headers provided.  The transaction's details that destroy the pegged coin and unlock the bitcoin will be used, but the signature can be trusted since it is in the block with the highest amount of work.  If nobody presents a higher difficulty block header that contains a contradicting transaction within the contest period, the bitcoins unlock.  But, to verify all this, the miners must be able to hash the headers.

Is  it possible for attackers to do this in reverse?

Take someone's cold wallet and lock them into an SPVPROOF on a SC while the true owner is indisposed for some reason? Or is this impossible because they would need the private keys to begin with? 

Presumably the sidechain would still require a valid signature to allow a transaction in a block.

you mean the SC block?  yes, don't these SPV proofs require 2 tx's each, one in MC and one in SC?

Essentially, what you are dealing with is a set of headers and a transaction.  The headers prove the transaction was added to a block.  (See section 8 of bitcoin.pdf).

What the sidechains idea adds is that instead light node verifying a bitcoin transaction, the bitcoin miners verify that the sidechain has a transaction that destroys sidecoins.  If this transaction goes uncontested, the SPV proof is accepted and the previously locked bitcoins are sent to the address specified in the destroy transaction.

i asked you before about this contest period.  what is the probability of an attacker constructing a fake proof in either direction.

what is this all about?  isn't this a fundamental change to how Bitcoin blocks are linked together?

We require a change to Bitcoin so that rather than each blockheader committing only to the
header before it, it commits to every one of its ancestors.


Yes a SC block.  Yes, there needs to be a destroy transaction on SC and a SPV proof on MC.

Did you try looking between sections 7 and 9?  That's where I found section 8.  (Hint, page 5).

An attacker can only fake a proof if they can fake a block, so it is up to the security model of the sidechain.

Can you put that quote in context (where is it in which whitepaper?).... I'm not sure quite what they are referring to.

pg 20 Implementation

why would an attacker have to fake a block when faking a SPV proof (tx)?  blocks are created by miners...

still don't see a section 8 on pg 5

who here has gone thru the math in Appendix B on SPV proofs?  is it sound and how does a compact SPV proof work in practical terms?

also, what is the structure of a SC?  does it start at the same block height (328739) as Bitcoin on day 1 with a complete history going back to the genesis block or does it start at it's own Block 1 w/o a coinbase?

i assume the crypto would be the same?  ECDSA and sha256, ripemd160?

New SC starts when peg is created (bitcoins are locked). All credibility for SC is in MC.
It does not matters what crypto will SC use. (it can use any cypto)

example:
SC can create paper coupons, this coupons is backed by bitcoin. (no new coupons can be created, only by depositing more bitcoins)
 - there is not digital ledger in couponSC
 - transaction are doing exchanging coupon by hand
 - somebody is doing 2wp exchanging coupons for BTC
 - no changes to existing bitcoin protocol is needed.

Some people in africa may find this useful. There is no way paper coupons can affect your bitcoins.
Only users of paper coupons take risk if they exchange this coupons for BTC they already owned and locked in MC.

Again "It does not matters what crypto will SC use. "

Yes... it does matter.
If a SC uses a compromised crypto, say one that incorporates key escrow, then the one with the escrowed keys can redeem the bitcoin that have been sent to the side chain.
Advocating for blind trust of all SC just on the merits that they are SC, is not a service to your readers.

There are 2 different things. 2wp(escrow), and side-blockchain crypto

Odalv I think we have consensus, I'm sorry any personal attacks.

if I have been understood, its only the later side-blockchain crypto that have the potential to change the incentives that give Bitcoin its value.

Congratulations, in 3 years on this board I've never once put someone on ignore because I usually like to hear what others have to say even if I disagree. But you are the first. It was a feat, you should be proud.

Thanks for that, your pedantry was becoming tiresome.
I think we both understand the mechanism of side chains.  For anyone else reading this I hope they aren't further confused by your explanation.
The block chains are the ledgers, there are as many ledgers as there are block chains.  Side chains create new block chains, each with their own ledger which are reconciled through what is being called a 2 way peg (though that is also an inaccurate term for the mechanism).  
Merging ledgers would be a destructive process where one block chain would then be abandoned afterwards.  I don't think you are meaning that is what is happening, because that would be incorrect.
I know gmaxwell likes the term 2-way peg from his explanation of this last December, I didn't much care for the term then either.  It is a useful shorthand, but it is going to confuse folks once this stuff catches on.

It is probably important to recognize that these are different units of account as well.  Otherwise there would be no need for the SPVs (and the term peg would be completely meaningless if there were only one unit of account).

Just growing pains. Issuing shares and not expecting regulatory interest is foolish. Presale of new crypto currency or stakes in a network on the other hand is much more interesting. Is.it.similar to seeking equity or is it a simple exchange of goods?

As I've mentioned before, sidechains would seem to provide a golden opportunity to monetize Bitcoin as a credible source of backing which they require in order to function.  They thus have a significant interest in keeping it that way.

Right now Bitcoin is fairly credible to at least a cross-section of us in the community because it is free of interference (no 'red-listing', transaction discrimination at the mining level, etc.)  Sidechains seem to me like the last best hope of keeping it that way.

My hope is that commoditization of ASICS and integration into heat recycling appliances distributed globally can solve that problem

I hoped for that as well at one point but I always considered it something of a pipe-dream.  Under an 'only Bitcoin for everything' paradigm it's probably completely out the window for technical reasons associated with data distribution.  With sidechains where people have a vested interest in reasonably finite chains of their favor, and where Bitcoin remains reasonably tight and compact, I could see more potential for such a thing developing.

While I don't necessarily agree with all of your constructs over the years here, I appreciate that you the potential for and disposition toward thinking.

It does seem to me that Bitcoin infrastructure provisioning is designed such that it will always approach unprofitably no matter what the growth rate, inflation rate, fee structure, etc.

It is worthwhile to note that different classes of entities can accept different levels of profit.  So, an independent enthusiast class individual might be happy to break even and occasionally make a few bucks while this is not an option for a large commercial.  Whatever the case, Bitcoin as implemented simply does not promote the individual class actor very well.

The take-away is that Bitcoin's only realistic hope is for infrastructure providers to monetize some other aspect of Bitcoin's existence.  For large corporate actors this is a no-brainier.  Monetize the intelligence stream as has been a well proven model over the last 15 years.  The big down-side of this is that actors who are able to monetize in this way are distinctly under the thumb of governments, and governments have a very strong propensity to exercise fine-grained control over their citizens.  Governments are inextricably linked to corporations and will be for the foreseeable future.

This is because successful sidechains would allow Bitcoin transactions to be disconnected from Bitcoin miners.

Interesting read but considering this is the premise of your scenario I have no choice but to disagree with your conclusions.

Txs fees are not escaping Bitcoin miners. As I've explained in another post, instead of miners sharing a % of the same pie, the txs fees are now split into different slices which are all available for miners to MM.

instead of doing drive bys hiding behind cryptic messages and never taking position why don't you counter argue my "contradictions"

Its going to be hard, I didn't see any contradictions. Your statement that the ledger remains the same is accurate, coins transfered to a SC are the same as coins transfered to an address. In both cases there is still one ledger, the mechanics may be different but its still one ledger. Its quite obvious they don't understand both the tech or the economic implications.


"There is one ledger"
Is untrue if (as it appears) you are referring to the side chain and Bitcoin, and true only if you are referring only to Bitcoin.
Each side chain has its own ledger, its own block chain.
Understanding side chains is much easier than understanding your descriptions of them.  

No NewLiberty there is in fact a single ledger in the system, you are wholly incorrect and do not understand the basic concepts apparently.

The phase "one ledger" means a single ledger of 21M coins. Yes in sidechains there are multiple separate blockchains, but the 2-way pegging system merges these blockchains into a single ledger. This is the basic 101 concept. Just because it is over your head does not mean that it is not the case.

There is one Bitcoin ledger.  There are also as many side chain ledgers as there are side chains.
So how many does that make?

(hint  >1)

Please do not pretend to know what is in my head.  Wink
I limit my guesses to what is in your head to the words that you write.
I hope I am being helpful to you in making more careful use of those words.

Let me explain it even more simply then.

The sidechain ledgers are merged into the bitcoin ledger through the 2-way pegging process, which creates a single merged ledger. Merged means one ledger, that is why the 21M cap holds.

The reason it is a single ledger is because the separate data structures are merged into a single data structure with 2-way pegging.

Congratulations, in 3 years on this board I've never once put someone on ignore because I usually like to hear what others have to say even if I disagree. But you are the first. It was a feat, you should be proud.

TL;DR: Sidechains (if they succeed) force Bitcoin's hand, although decades in the future, in setting an inflation rate determined by the market, in order to tie miner's subsidies more exactly to the primary service they perform: that of securing Bitcoin's store of value. This is because successful sidechains would allow Bitcoin transactions to be disconnected from Bitcoin miners. Bitcoin therefore could not rely on transaction fees for its network security incentives. Sidechains would have made it clear that transaction functionality is not intrinsic to or inseparable from the Bitcoin network; only the store of value function is, and therefore miners must be continually rewarded for maintaining this function alone, for the lifetime the network.

While I don't necessarily agree with all of your constructs over the years here, I appreciate that you the potential for and disposition toward thinking.

All I'm saying is the Blockchain is the money, dont mess with it, I care about my private keys like everyone else but the value is in the ledger moving value to other ledgers is actually a threat. This isn't code, it's and economic experiment that parent child relationship is not defined in code, its defined by market forces, I'm not trolling, to be clear I am pro secure trust free 1:1 Pegs that can be diploid within the existing feature set of the Bitcoin protocol, they are an essential innovation to the future of Bitcoin.

I am opposed to changing the protocol as proposed by BlockStream, here’s why?
It changes the incentive structure that gives Bitcoin its value. Miners will eventually have to MM Bitcoin not for profit but for some other reason.  

Adrian, please.. why do you repeating the same mistakes all over. Sidechains are not messing with Bitcoin, they are improving it and ensuring its preservation and adaptability to future threats. The value does NOT move to other ledgers. The ledger remains the same, its token are only given more features to work with.

Only the creation of a new coin creates a new ledger and this is not the purpose of sidechains.

You keep parotting the same "it changes the incentive structure". In reality, it improves the incentive structure for miners who are no more dependent on ONE chain. They now have a whole ecosystem of interconnected chains that are each valued for their particular characteristics. The mother chain being BTC's, it is the least likely to be abandoned

This one is amazing.  
Practically every other sentence contradicts each other.
