Re: OKEx Suspends Withdrawls

They announced they reopen: https://www.okex.com/support/hc/en-us/articles/360052758931-OKEx-Official-Announcement-Reopen-of-withdrawals-and-other-related-updates

It's still quite vague, but it seems to confirm that the issue was the arrest of Star Xu. Their description of the key backup is quite worrisome, still:

Quote
The reason for the suspension of withdrawals in this specific incident was because a private key holder was not able to authorize transactions. OKEx has always used a backup mechanism for private key holders to ensure that each private key holder can trigger the activation of the backup private key in the event of long-term incapacitation, such as death or memory loss.

However, we unfortunately failed to include other specific scenarios, such as private key holders becoming unreachable due to unforeseen circumstances in our contingency plan. In this specific incident, therefore, the ultimate resolution for the private key holder’s short-term incapacitation was not a technical one.

What does that mean? I interpret that they have Star Xu as a necessary part in both the main and the backup paths. That if his main co-signers went missing, he could "trigger the activation of the backup" but only he was able to do it.

That could be read, alternatively, as that there were timelocks involved. However, I think that's not the most likely, for many reasons: they don't explicitly mention timelocks, their known cold wallets are plain multisig with no fancy scripts, suspension covers all coins not just Bitcoin, etc.

I don't think getting paid something like 80 cents on the dollar is worth it. Why don't traders just open another account at another leverage exchange like Binance Futures or Bitmex. Then go 100x their account when they think BTC is going to go up and basically try to get liquidated on OKex and get the entire sum on the other account minus fees on both exchanges.

Wat? Even at the lowest margin tier (which is $50k max, i.e., at 100x salvages $500 max), liquidation costs amount to 0.5% which, at 100x, would take 50% of the margin. Add an additional 0.06% -> 6% and whatever the fees at the other exchange. A ruinous strategy.

Be cautious with services generating your addresses, you should look into bitcore.io it's easy to use


Here is how you can install it and run it
https://github.com/bitpay/bitcore#bitcore



Please, don't. Bitcore wallet / Copay is unmaintained, at least on the Bitcoin side (they focused mostly on Bcash).

Electrum has easy multisig and it is also cross-platform.

https://1fox.com/ is still up. Wasn't this by the same people running the 1broker? Or were they interested only on that fiat/stocks/other trading?

i would definitely withdraw any funds from 1fox ASAP until the dust settles.....
A better option to be done than to be late and regretting later on when your funds is on hold.If 1Broker is being  seized then we can presume that related or similar exchange will be already on the list.So we should prepare for that.

Wow! Bitcoins seized ?

Surely the FBI does not have access to cold wallets  Huh



Bitcoins are not seized. I was able to withdraw mine after they processed my request for 2+ days. It's alright.

how? where?

Total shitposting. How to withdraw if you cant access the seized site?  Cool

You could not, if it was. Fortunately enough, it is not: It is just the domain that got seized. Site is still available via hosts file redirect
Code:
104.25.96.11 1broker.com
or, I believe, via the app.

What the fuck ? 4.6 bilion ? 10% premine ? Nice scam  Grin

If max supply is 4 600 000 000 so why on coinmarketcap i see "max supply 210 000 000" ?   

WTF

This is about the other Bitcoin Diamond, the one that is a fork (as in blockchain fork, not codebase fork) of Bitcoin. That one has a 210M supply (10:1 airdrop w.r.t. BTC) and it is also a premined scam, just not this one in this thread.

Looks prone to abuse. Does the BTC address need to be funded? I tried an unfunded address and it got accepted. If yes, at which blockheight?

What is preventing someone from creating 1000 addresses, thus claiming 5000 BTR? Or if there is need to have the addresses funded, spam them with a small amount?

Nice, so even at the certainly overpriced rate of $5400 per rig, you can now buy this "token" for a 5000% premium only.

Remember that each token represents a 5-millionth of a rig.

Re: BYTEBALL: Totally new consensus algorithm + private untraceable payments

The distribution model encourages holding, month to month, so I expect to see the price steadily increase.

Not really. New issuance is fully proportional, so it is actually debasement. Because of this, no value changes hands and, rationally, the market cap should stay the same.

There is an additional issuance to BTC holders too, but it is too small to be relevant.

The transition bot has gone silent for me and does no longer reply to anything. Even if I delete my profile, it still does nothing. This is very strange. Did I trigger some IP ban or something?

It seems this is an issue with the bot. When first pairing the device with the bot, it replies with instructions to linking, however, after closing and reopening the wallet, there doesn't seem to be a way to make the bot display the linking instructions again (or anything else).

Even after a full reinstall? (that is, with a newly generated wallet)

Anyway, do you know what are those linking instructions?

Sukrim, the actual implementation has more casuistic over what is described in the paper. This is the case for both Ripple and Stellar.

What makes you think that Ripple is not vulnerable to the consensus fault and subsequent reorganization that affected Stellar? (other than the fact that it has not happened yet)

Re: CoinShuffle: Practical Decentralized Coin Mixing for Bitcoin
by

on 15/10/2014, 19:41:02 UTC
Is a full working version of coinshuffle being developed? The research site says the current version was just a proof of concept for testing and not usable for real coins.

Amir says it's being worked on for Dark Wallet.

I thought they were implementing CoinJoin instead.
EDIT: true, Amir confirmed that: https://www.reddit.com/r/Bitcoin/comments/2ijsw1/the_coming_of_darkwallet/cl2qow6

On the other hand, I see a problem with CoinShuffle. The participants are supposed to sign their messages "with their addresses"; this assumes that the inputs they provide were paid to standard P2PH addresses, but they cannot use outputs sent to P2SH (those starting with a 3, e.g., "multi sig" addresses). Participants could still be required to reveal their script and then sign their handshaking rounds with a key contained there (if there is any).

Re: [ANN][CATc] Cataloniacoin · Conference soon thanks to a Google dev · SCRYPT-N
by
oriolpont
on 28/06/2014, 15:27:25 UTC
I think the proyect is abandoned , but i think Catalunya needs a great proyect of a national cryptocurrency, in November there will be a referendum about independence from Spain, its a great idea to Catalunya to be backed off by an alternative currency, a innovative one, providing people a new way to improve the economic wealth of a new formed country. More than Auroracoin (i think in the beggining was a great idea), this new X cryptocurrency have all the winning cards to become a key point in the adoption of decentralied money. I think there is time left to the dev team to go ahead with the proyect and take it seriously, if not another dev team could make another launch.

I think the key is to inform political forces of pro-independency parties of the feasibility of making a national cryptocurrency, the big pro-independency party is an anticapitalism one, ERC and i think they will be interested, Spain allways arguee about Catalunya never will be aceppted in EU neither EURO currency if independence wins, having the posibility of making a strong national crypto is more than a threath to Spain.

Well, I definitely do not think that that new project should back off in light of Catalonia's independence  Wink. You probably meant that a future Catalan currency could be backed by the new country, which is valid but unnecessary. In my view, the point of cryptocurrencies is that they do not need any backing. The Catalan people can use bitcoin or develop their own cryptocurrency without asking anybody's permission, with or without independence.

The only point of national (or group-restricted) coins is if they can provide something unique that would be impossible in the universal framework, e.g., equal initial distribution. Auroracoin and all the others have failed in that only a tiny percent of the population actually claimed their share (they cannot grow now, because if they did they would be sharply unequally distributed then). Consequently, any valuable national coin should avoid any premine and airdrop, and be gradually distributed instead to provable individuals, as I proposed a few posts ago:

Re: [ANN][RSC] Research Support Coin (RSC) - mining with purpose
by

on 18/05/2014, 22:34:52 UTC
I cannot see how RSC could ever be valuable.
[..]

Mine RSC, sell if for XRP. If you don't like XRP you can sell if for anything (e.g. for LTC).

I'd gladly sell. But selling requires someone buying, and I can't see who'd rationally buy.

But someone is buying :-)

ASKS
Ask Price XRP / Size RSC / Sum RSC
0.02000 / 3,000.00000 / 3,000.00000
(...)

Those are asks not bids! You just showed the opposite: someone is selling.

To be fair, there is also a rather thin bidding-side book: I count a total of 2100 XRP (around $10-15) with most of these at 0.000001 (one millionth) XRP per RSC. Even the average bid, 0.0001 (a tenth mill) XRP per RSC, is ridiculous: electricity costs orders of magnitude more, let alone a DigitalOcean droplet.

Anyway, my comment was about the fundamentals, not the actual book. The OP and a few dumb speculators are bidding these few dollars that we observe, but I still do not see how any rational research supporter would ever buy RSC in any significant amount.

Auroracoin is more expensive only because it was the first country-scam-coin. It still retains some speculative pumping from non-Icelanders, but only because it came first.

The main problem with Auroracoin, Spaincoin and the like is that their airdrops are not fair at all and do not promote any growth in coin adoption. They promise equal distribution among citizens -- this is their only real advantage over bitcoin -- but they are instead shared between the earliest adopters only (except the small breadcrumbs left for mining).

This is quite similar to the case of the distribution of Counterparty: Its devs claim that XCP were fairly distributed because users claimed them through burning bitcoins. However, once I learned about it (it hit the frontpage) and was willing to burn my bitcoins, I discovered that it was no longer possible. Top-earliest-adopters get all; how could this ever be fair?

The only justification for an early airdrop is that, before it takes place, the coin is heavily centralized (why the launch should then precede the airdrop escapes me though). Spaincoin for example has the worse of both worlds: most of the coins will be distributed by the end of this month, yet small portions will be left in dev's hands for an unspecified time.

National coins will not succeed unless they are truly distributed among the people. If it is just to the earliest adopters, there will not ever be any newer adopters. However, this can be entirely avoided. OP, could you please say word or two about what I proposed?:

A somewhat more radical approach to achieve mass adoption and fair distribution would be to avoid any airdrop at all. You could simply pre-assign an equal share of coins to every person (based on DNI or government-issued certificates): the monetary base will proportionally scale with coin adoption, i.e., no rational reason for speculative hoarding nor for dumping (guaranteed scarcity).

This can be made by relaunching without the premine and with a protocol modification instead: at any block, a coinbase can be generated through proof-of-identity, which is essentially showing an unseen ID number and its valid signature. Fraud is not possible as long as the ID issuer can re-issue certificates but always to the same ID number (yes, Spain is a tightly controlled police state). Theft is possible, but it implies stealing the certificate token and its passphrase (i.e., a full extent identity theft).

Most importantly, we do not need to check for expired or revoked certificates at mining time: we can let some nodes do the DB queries and let them issue proofs of revocation before the coinbase maturity for a small reward (to avoid spam, these proofs of revocation would need to burn some coins and be rewarded only if the miner confirms the revocation; also, blocks include only one such transaction per certificate - the rest are rejected without burning or reward).
