Somebody has been impersonating me from Nov 7 to Nov 10.

Of course I have changed my password and deleted the (about 30) fake posts. The fake posts were mostly inoffensive with some promotion for scamcoins, which is consistent with a paid spammer.

I am posting this to leave a record that may be useful if this happens again.

I don't post frequently and never advertise scamcoins, so if you see that kind of posts it wasn't me. Please IM me if this happens again and also send email (I am easy to find online).

In fact, I foresee considerable opposition to implement sidechain hooks in Bitcoin Core. But sidechains can add so much value to Bitcoin that the change is likely to be implemented. If not, Bitcoin might soon become obsolete and give way to an equivalent network that implements extensibility via sidechains.

I wonder what happens when the regulators realize that sidechains can put privacy and anonymity back ;-)

But isn't innovation outside core exactly what sidechains are for?

BITCOIN

A stupid rich person can do everything - he just has to pay a smart person to do it.

I am thinking of something like this:

- Users can buy micro-shares of public companies. For example a user can buy 1/100 of a FB share (currently trading at $93) for $0.93, and pay in bitcoin.
- The money is used to buy real shares. In the example, as soon as there are enough buyers for one FB share, the operator buys one FB share and the user receives 1/100 ownership.
- Users can trade micro-shares.
- Users can sell micro-shares to cash out. For example if 100 users want to sell 1/100 FB each, the operators sells a real share and pays the users.

Does something like that (or similar) exist?

Good article! There are discussions on adopting Bitcoin as one of the official Liberland currencies on the Liberland Forums at liberland.org.

The realist in me thinks the project doesn't have a chance because the powers that be will crush it in no time as soon as they notice, but the optimist in me keeps hoping. If Liberland survives, it could make a big impact. In particular, supporting Bitcoin would be a win-win alliance.

What I would use the card for: spending bitcoin everywhere, ATMs
Entry Number ([previous entry number]+1): 7

I did an end-to-end coinb.in test.

1 - I created and funded two wallets A and B

2 - From A I created a 2-2 multisig address with the public keys of A and B.
Address:
3LvaMMABYXamGkH1DQbLfB4pYp8pU3of7T
I saved the redeem script.

3 - From B, I sent money to 3LvaMMABYXamGkH1DQbLfB4pYp8pU3of7T
Transaction:
https://btc.blockr.io/tx/info/230f6e6c3d8bca2686cdfaeda7b24f1f08d657f82cdb82a687a89834e84be52c

4. From A, I created a transaction to send the unspent output of 3 to an external address, loading the inputs from the redeem script (output of 2).

5. From A, I signed the transaction and verified it (signed 1 of 2 OK).

6. From B, I signed the transaction (output of 5) and verified it (signed 2 of 2 OK).

7. From B, I broadcast the transaction (output of 6).

8. Received:

I will do more tests appropriate to the specific use case that I have in mind. In general I thing coinb.in is great but perhaps too difficult for today's casual users - those who need click and simple one-click solution and are unable to open a new window or copy/paste. However, I am sure that it's easy to adapt the user the interface to specific use cases, hiding complex features and selecting the needed data (e.g. key and transaction to sign) automatically.

Awesome indeed.

Thanks gmaxwell.
Re 2- is there a hosted wallet with a simple UI to retrieve a public key and sign a multisig transaction?

1. Why the f# didn't they add the option to use also bitcoin addresses (instead of only public keys) to create multisig addresses? I am sure there must be a strong reason but I don't see it at the moment. Many users don't know their public keys immediately, and some (e.g. Circle etc.) don't know them at all.
2. When a multisig transactions has been partly signed, how can the other allowed signatories be notified? (besides emailing them).

It wasn't that, it was a blocked popup. I enabled popups and everything worked. I deposited $5 in bitcoin to my (previously unused) Neteller account. Then I could verify the account to raise daily limits (I had to send an id document scan to do that) and now I have all options, including the virtual credit card (free) or the plastic credit card (one time fee of $12). I think I will get the card to offer myself the experience of withdrawing cash-from-bitcoin and paying with bitcoin at the mall.

Received from Neteller: Deleting Cookies and Internet History should fix the issue that you might be experiencing.

Sent to Neteller support: Hi, I just opened a Neteller account. The Bitcoin deposit feature doesn't seem to work - the system says "Selecting "Confirm" will launch the third-party processor and allow you to complete this transaction," but nothing happens when I click Confirm.

I created a new Neteller account from Hungary and the bitcoin deposit option is there. But it doesn't seem to work at the moment, perhaps it isn't fully implemented yet.

I am thinking again about this idea, which seems more and more appealing and useful.

In this scheme the rest of the world acts like a sidechain - x BTC are moven from the main blockchain to the sidechain, traded (as a whole) on the sidechain, then eventually brought back to the main blockchain.

Of course it's impossible to trace the movements of the x BTC on the sidechain.

TTBit did you implement the scheme that you described?

Just found out about Augur, very very cool. I started some threads on this forum to inquire about Bitcoin prediction market development projects, but didn't find anything really wow. This is the most promising project that I have seen so far.

Impressive! A potential game changer.

What publicly traded companies (NYSE, NASDAQ, OTC) are developing Bitcoin technology or applications? I know of Overstock, Bitcoin Shop and the Winklevoss ETF, but perhaps there other options for traditional investors that want to invest in the Next Big Things.
