i just did the next buyback http://cryptofresh.com/b/3169440

we bought 13.33 METAFEES for 0.32 BTC and will burn them the next days. The total supply for METAFEES will be going down from 6220 to 6206.67 METAFEES.

How did the supply drop to 5416   ??

- I can see adding sidechains for other major cryptos such as litecoin and peercoin.  Wouldn't it be possible now to trade amongst them as well?  Huge liquidity.

this may not by true... so do not take my words as final... but I think we could integrate with everycoin which has multisig. But... it will require to run full node of that client by all witnesses. So it would be difficult to run 20 full nodes of different coins. So (in my opinion) we should focus on:

* BTC
* ETH
* DOGE :)

Agreed  +5% +5%

A bitcoin sidechain is quite enough to be getting on with for now.

If I have 100% of my vesting balance available to claim.  Is there any benefit in not claiming it now?


Can I continue to earn coin days that will allow access to other operations that demand 90 day vesting period but earlier than the 90 days as I have saved x number of coin days?

* The witness who hold the second key could be the same person who deposited the BTC which is supposed to be locked, but actually the person have both keys, she can just unlock the fund without destroy the issued bitBTC.

2 the software will only allow a witness to sign the bitcoin transaction once the corresponding SIDEBTC has been destroyed. Remember SIDEBTC is not transferable only BITBTC is.
Re 2): How does the software prevent someone with both bitcoin private keys from signing a "bitcoin" transaction? They would sign it on the bitcoin network, which doesn't care about the rules of the sidechain.

Who would have both keys? As a depositor you guard your 1 of 2 key as well as you would a single key.
abit's original point was simple, so I've just requoted his point, your reply,  and my reply. To answer your question: the
witness would have both keys: his "witness" key and his "sender" key. With these two keys, you can sell your BitBTC, then release your BTC.

So basically you're saying that witnesses would be able to double spend their own BTC by redeeming SIDEBTC and dumping BITBTC at the same time?

In general, I think this scheme is overly complicated and prone to some basic pitfalls. First and foremost, with potentially locked up BTC forever, all the BitBTC isn't redeemable for BTC, so it shouldn't trade as 1-1 for BTC.

I think BM's solution is much simpler, easier to understand, and therefore easier to trust. It's pretty safe except in the case of large scale collusion by the custodians of the SBA keys. To reduce this chance for collusion, the custodians could be compensated by some stream of income that goes away if they do collude.

Obviously there's political decisions involved in determining how to balance the amount of income to the custodians, the number of custodians, etc as the balance held increases. The biggest problem is this regard is probably the limited size of Bitcoin's multisig.
I'm glad to see a BTC expert came in.

Imo what we need is a reputation system which will provide trusts. "Reputed signers hold the keys".

By the way multi-sig feature of BTC is too expensive, perhaps we can't afford the operating cost if eventually implemented the side chain thing.

Who would have both keys? As a depositor you guard your 1 of 2 key as well as you would a single key.

Obviously we should be pushing to get a sidechain implementation going ASAP.  But I think we're dramatically overcomplicating it in this thread and should probably leave the precise details to the devs (primarily @bytemaster). 

Beyond that, I think we should be concentrating on pushing to incentivize a) creation of the primary fiat BitAssets and b) participation in BitAsset liquidity pools, among other liquidity measures. 

Speaking of liquidity, I think we should be doing what we can to establish robust markets in any new cryptocurrencies that hit the market.  The Lisk ICO will go for another 3 weeks and then it will launch and trade on the open market.  I'll probably say this until I'm blue in the face.  But we should make sure we are among the first exchanges (if not THE first) to trade Lisk.  That would generate plenty of buzz and new users for the DEX.

We really need to get serious about making some of these pieces of the puzzle come together.

@bytemaster solution is just a bitcoin master wallet where the witnesses share the private keys and issue IOU tokens much like OPEN.BTC minus the multisig

Can we keep on topic with this thread. Please start a new thread if you want to discuss adding lisk.

I don't know the details of bytemaster's solution.  What are the pitfalls of it?  Sounds like a straightforward solution:  bring bitcoin in one-way via sidechain, treat it as a token to trade inside bitshares, redeem via a convert to BTS then to shapeshift.

It is straightforward and will be much better than what we have now.
I just think we should be more ambitious and create a solution where the depositor at least retains control of half of their private key. Ie a true sidechain.

In this case, only those that provide real BTC will be able to withdraw real BTC ..
That's a non-starter IMHO and I would personally prefer a big multisig scheme instead ..

Correct. But this would create the liquidity and the low costs that would allow for a shapeshift style bridge from BITBTC to realBTC.

Before I start, here is a good explanation of what sidechains are: http://gendal.me/2014/10/26/a-simple-explanation-of-bitcoin-sidechains/

Amanda discussed them on yesterdays daily decrypt also but the explanation above is better imo: https://youtu.be/Q6VwH1yKjdI

This is my proposal of how we should make the bitshares blockchain a sidechain for bitcoin and take the glory for actually implementing it before any other blockchain does.

Depositor sends bitcoin to the bitshares network.
The bitcoin address sent to is now controlled by 2 keys required to spend from it. (multisig)
One key is held by bitcoin depositor and second key is held by bitshares witnesses.
This bitcoin cannot move until both original depositor and a witness sign a transaction to send it somewhere else. (it's effectively frozen)
The witnesses can now issue a BTC token 1:1 for the same amount as was deposited to the depositor (lets call this SIDEBTC)
Original depositor now has SIDEBTC in his bitshares wallet which is non tradeable and cannot be transferred.
SIDEBTC has only one purpose which is to be used as collateral by the original depositor to create BITBTC.
If collateral is denominated in same currency as the bitasset it is creating there is only need for *100% collateral not 200%+
This BITBTC created from SIDEBTC can be transferred and traded.

For the depositor to get back their real BTC they must settle their BITBTC debts first then instruct the witnesses to redeem their SIDEBTC and return their real BTC back to them. 

if the original depositor never redeems his SIDEBTC, nobody including the witnesses will be able to access that real BTC again.
This means technically speaking the SIDEBTC is not real collateral. It means the committee can freeze it but not have access to it themselves.
Because of this we need ensure that almost all SIDEBTC holders redeem it for real BTC in the future.
Now earlier I said only *100% collateral is needed to create a bit asset if both asset and collateral are the same currency which is true.
But to make sure almost all SIDEBTC is redeemed in the future we should make the collateral requirements for BITBTC higher than 100%
For example we could require 110% SIDEBTC in collateral to create 100% BITBTC
This should make sure that all SIDEBTC owners will make sure they can redeem in the future.


Points to note.
-This sidechain proposal for bitcoin is intended to eliminate the need for bitcoin denominated UIAs as it would be free to transfer and trade and be 100% liquid at peg with zero chance your btc could be stolen. 
-Witnesses cannot steal BTC under any circumstances. The worst they could do would be colluding to freeze the bitcoin.
-Having the collateral in the same currency as the the bitasset also eliminates the possibility of a margin call.
-Forced settlement would not be possible because SIDEBTC (the collateral for BITBTC) can only be moved if the original depositor signs.
-SIDEBTC is not technically collateral because the real BTC cannot be recovered by the bitshares network if the original depositor never redeems his SIDEBTC

I think today went well.

theres still lots of depth on usd:btc

327
it looks pretty awesome! :) I want to have situation like this... everyday! :) But you know what? Now we all know, that this is possible :)

If anything, a monthly event could be done until people get used to it and it remains constant

Looking good!  Yeah, liquid Mondays?  Or we could all just agree to just trade on days that end in ''y"   :P

"Liquid Mondays" I like it, sounds like a band

328
right now spread is almost zero on USD:BTC

329
I've been wondering this to but I don't think it's possible.
let me know if you find out.

Settlement has nothing to do with liquidity (in core smartcoins like USD, EUR, CNY, etc..) IMHO

maybe I misunderstand what you're saying.
Settlement has everything to do with liquidity.  That's its only purpose. 
It guarantees up to 2% (or whatever it's set to) of daily smartcoin supply is liquid at the settlement price.

It is in effect a standing order to buy that smartcoin. (with 24 hr delay)
sure .. for that direction there is everything fine and we do have 2% of supply in instant buy orders for smartcoins ..
the liquidity issues are on the other side .. no one wants to sell his smartcoins .. not even for a 5-10% premium (depending on the actual asset) ..
simply because we don't have a big on/off ramp for bitassets ..

Forced settlement is guaranteed buy side liquidity at the peg.

I think we need some sort of guaranteed sell side liquidity at the peg+10%. This would have to come from the rerserve pool imo.

One of the benefits of @Empirical1.2's idea is that yield can be directed not only to BitUSD longs, but also to BitUSD shorts.  Also, it stands to reason that a subset of the people buying BitAssets for yield would also be interested in participating in a liquidity pool to gain additional yield.  Funds from such a pool can then be used in conjunction with funds from the reserve pool to create liquidity on both sides of the peg.
What about BMS concerns about being long and short at the same time. It artificially increases supply but not liqidity? Also there's no need for reserve pool subsidies of the buy side because of forced settlement.

Increasing BitUSD supply via yield harvesting is still a positive imo because...
 
- It removes BTS supply from centralized exchanges
- Converts many BTS holders in Smartcoin holders (the product we are trying to bootstrap)
- Converts many BTS holders into longer term yield seeking holders vs. speculators http://bytemaster.github.io/article/2016/01/04/The-Benefits-of-Proof-of-Work/
- Makes us the Crypto USD market leader by value and numbers of holders thereby making us the most lucrative market for merchants.
>70% of BTC is illiquid and hasn't moved in >6 months, but the number of holders and value of their holdings is the most lucrative crypto market and has attracted over 100 000 merchants. This utility increases liquidity and usage. http://www.ofnumbers.com/2014/11/22/approximately-70-of-all-bitcoins-have-not-moved-in-6-or-more-months/
(Whereas why would a lot of merchants want to make the effort to offer their product and services in a much smaller market with fewer users? Let's become the USD crypto market leader fast.)

Nearly all other promotions and developments cause the BTS price to fall in the short term in the hopes of creating demand in the future, dilution for yield should increase the BTS price (via increase BitUSD (BTS) demand in the short and medium term) https://bitsharestalk.org/index.php/topic,21641.0.html

Incentivizing liquidity, incurs a constant cost but not necessarily constant net new demand for BTS. (Without yield many seek crypto USD only temporarily during BTC/Crypto declines.) By offering yield we will bootstrap BitUSD (in a way that should actually increase the value of BTS from the outset and be a cost that can be mitigated by shareholders if they engage in the network beneficial behaviour of yield harvesting.) 

So personally I think we should offer dilution for yield during the growth phase of the DEX as well as conservative liquidity subsidies.

I think this method may help but will likely be too expensive. It doesn't guarantee liquidity either. I much prefer the idea of providing guaranteed sell side liquidity at feed +20% funded by the reserve pool.

(I don't think the cost is high as it creates more demand that it costs from the outset and can be phased out if it doesn't and the cost can be easily mitigated by yield harvesting.)  I don't mind using the reserve pool for things, but I'm not a big fan of making it the buyer of last resort and hence over-exposing BTS to risk. So it should have limits imo. I suppose 20% is pretty wide though.

I don't know if the following is true, but given most agree yield harvesting would create millions of BitUSD,  it may make liquidity easier as with all that BitUSD already created and only a small amount needed for liquidity operations we may be able to incentivize a good amount of daily liquidity participation in a tight range for a low cost like NuBits liquidity pools? http://cybnate.github.io/index-liquidbits.html (Vs. now where we're trying to incentivize the creation of initial BitUSD as opposed to the buying and selling of already created BitUSD?)



It would be the seller of last resort not the buyer of last resort.
if the reserve pool only sells smartcoins at +20% and buys them back at 0% through settlement this should actually be profitable for the reserve pool.

If yield harvesting was introduced I would just create bitusd to harvest I wouldn't sell any in to the market so I wouldn't provide any liquidity under this proposal.
The same issue persists, smartcoin creators rightly fear not being able to cover.
