tamagucci.info is having some issues with memory leaks. I do not know which one is causing the problem. Insight is for sha256 algorithm and tamcoin is using scrypt. I will fix if i can or use alternative open source explorer.

I'm just going to say that this is might be a classic pump.

https://twitter.com/VersaCrypto

Until a few hours ago, the twitter account was spamming with buy Versa tweets and now it's all deleted. Even I saw a tweet that saying Versa will be 3000~4000 satoshi soon.

This could be worse than "noticed pre-mine". All the dev(s) have to do is buy Versa with their own bitcoin and pump the volume and hold something like 80% of the coins. The dev(s) will get their bitcoins back anyway from ICO.

Just my opinion.  Wink

What will happen to the remaining coins from ICO? What is the incentives for devs? Did you bought coins from ICO or will some portion of coins distributed to devs?

Re: Question: Multi-Sig Instant Transfer
by
JMG
on 30/01/2015, 00:30:12 UTC
Bitcoin-QT can do this because the accounts are not actually tied to bitcoin addresses. An account is more like an entry in a DB and can just be updated arbitrarily. The downside to this is that it involves a lot of trust. If 2 people had access to the same wallet.dat, either of them could take all the money.

There are protocols that make transferring bitcoin between 2 parties instant, but they are slightly complex. These protocols also tend to rely on transaction being non-malleable (some overcome this challenge). In general, they start with party "A" sending a large transaction (T1) to a shared multisig address, then a transaction (T2) splitting that transaction between both parties.

T1 - A -> ($100 -> shared multisig)
T2a - shared multisig -> (95$ -> A, $5 -> B)
T2b - shared multisig -> (90$ -> A, $10 -> B)
T2c - shared multisig -> (85$ -> A, $15 -> B)
...

Each of these variants of T2 can be proposed by party A to party B instantly. To close the instant payment channel party B signs the last T2 transaction and broadcasts it to the network. There is also usually a fail safe using nlocktime so that if party B doesn't claim any of the transactions after a certain period of time, then party A can claim all the funds in the shared multisig.

Hopefully this is clear.

It's very helpful. Thanks!

Question: Multi-Sig Instant Transfer
by
JMG
on 28/01/2015, 15:35:59 UTC
⭐ Merited by ABCbits (2)
Hello,

I know that one wallet can generate multiple accounts and can transfer bitcoins instantly between those accounts(Bitcoin-QT).

Then could one wallet generate multiple multi-sig accounts that are belong to different persons(one has know accessibility of another) and transfer bitcoins instantly between those multi-sig accounts? Say one wallet generates 2 sets of 2of2 multi-sig account and each one belongs to Adam and Bob, and Adam cannot touch Bob's bitcoins and vice versa. Then could Adam instantly transfer bitcoins to Bob if multi signed?

Or is that one wallet can only generate one multi-sig account and, in order to send bitcoins, the transfer must take blockchain?

Thanks.

Re: Trade Bitcoin without Real Money: Virtual Exchange

Finally you can trade bitcoin via iPhone app!

The app is developed to serve Bitple(http://bitple.com) users better on mobile platforms and give push notifications for their trades.

Worried that the app might not get approved. And it took weeks to be approved(unusually). But finally it got a green light.

It's not a best bitcoin app out there. But I think this is something for the bitcoin community.

Bitple.com uses real-time data from Bitstamp to enable users to trade bitcoin without risk and without spending real money. I expect Bitple.com will help those people who want to try their new trading strategies and those who feel suspicious about bitcoin market but want to try out without risking anything. Or if you believe that you are one of the best bitcoin trader in the industry, now there is a way to prove it to the world by sharing your trades from Bitple.com (http://bitple.com/JMG99).

I am glad that this problem is now solved:

Let us know which additional exchanges you would like to use.

What about an alert when the (medium) price difference between two markets is above/below a user defined value?  Grin

We will consider the option for future update.

Thanks.
