Title: Auction for a bitcoin bond
Post by: grondilu on March 31, 2011, 08:06:39 AM
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

As a proof of concept, I hereby launch an auction for a bitcoin bond.

This means that I promess to pay a certain amount of bitcoin (called "nominal"), at a certain date (called "maturity").  The nominal is 100 BTC.  Maturity will occur at block number 120,000.

I sell this bond in an auction process that will occur on this thread.  To bid, just post a message with your bid in bitcoins.  Auction will end at block number 116,000.  Paiement should then be done within 10 blocks.

No starting price, but if at the end I'm not happy with the final winning bid, I will cancel the auction.

If selling does occur, I will materialize it with a GnuPG signed document where I will mention whe nominal, the maturity and the bitcoin address where the nominal should be paid at maturity.

Happy bidding!

I bid 100BTC, which means that if I win, I'll just let you keep the darn bond.

OK, to be honest, I'm really unsure how this works. You want someone to pay you now, in exchange for a payout in the future?

If you bid 100 BTC, this means you'll pay me 100 BTC at block 116,000, and I'll pay you back at block 120,000.  You would lend me money at zero interest rate.

I can't accept this bid, since so far the bitcoin network only allows paiements with 0.01 BTC precision.

I understand you must pay the bid price now, and he will repay you the nominal value (100) at maturity time.
It's like a loan backed by a bond that you can also negotiate at market prices before maturity.

My bid is now 91.

That was before I saw you did not accept 90.000001 bid, but for sure there will be higher ones too.

Can you give a rough estimate in real calendar time when the bond will expire, for those of us who don't understand blockchains?

The time length is 20,000 - 16,000 = 4,000 blocks.   There are about 6 blocks per hour,  so 4,000 blocks is about 666 hours (?! number of the beast??  didn't do that on purpose!)

666 hours is 27 days, so about 4 weeks.

This woudl allow the winning bidder to sign the final bitcoin address.

I will accept a bid even if it's not signed.  But precisely because it's a POC, we should look for the way to do things properly.

But I'm not sure it is really important.  It's not related to the bond process, but to the auction process anyway.  I don't think we would need it if we were on biddingpond, for instance.

The date is in the signature, so there's not much chance of confusion...

I'm not sure the timestamping in a GnuPG signature is trustworthy.  If it was, the bitcoin network would use it instead of a distributed time server.


Anyway, now that I think about it, signing bids is not necessary.  It is really an auction protocol issue.  Here the proof of concept is about bonds, not forum auctions.

What has to be signed is my promess to pay.  So once I get a bitcoin address from the auction winner, I'll sign it along with the bonds terms, and that will be all.

I would bid 95.5 BTC but if the 116000 block happens during the night at my timezone, I wouldn't be able to send the payment in 10 blocks which is less than 2 hours. Please extend the payment window to at least 60 blocks.

I wonder if this will become the standard for Bitcoin loans. This seems a lot simpler than establishing some obscure interest rate.

No, sorry.   You just have to stay awake.  I don't want to wait 10 hours for a paiement.

I think it's a standard procedure in bond markets.

Sure -- but with Bitcoin being non-inflationary and such, establishing interest rate-based loans is a bit difficult. It would be nice if this bond concept was applied to lending Bitcoins overall.

OK, your auction, your rules but if you want to set up a bitcoin bond standard, such rules are rather bizarre in any bond market.  Bonds usually have 2 days settlement and the bond duration starts at settlement, not the auction time.

I have no idea what justifies those two days settlement, but I suspect it is related to clearing.  And there is no clearing with bitcoins.

Hey, nice thread to measure traders' expectations.

Looks like people expect an inflation of BTCs in the near future. Almost everyone would rather have less than 100 BTC now than 100 BTC later.

Might be an indicator for traders to sell some BTC. Maybe I should have waited with my selling offer... on the other hand, maybe the traders only didn't appear because the amount is too low? Who knows~

A website that manages loans like this might be a good idea for a project. It could calculate the appropriate starting bid and bond amount based on the specified minimum loan amount and maximum interest rate. I'd certainly be interested in loaning to reputable individuals. It might be fun.

I agree.  For those who haven't seen the thread, there are some interesting ideas about how to operate a Bitcoin lending website at http://bitcointalk.org/index.php?topic=5027.0

I would love to make such a site, but already have too many irons in the fire

I did sell some of these 96.1 BTC and then bought others at a lower price.

But I could have used my own bitcoins.

So to tell you the truth, it was much more of a proof of concept that I wanted to make.

Might be usefull for my reputation if I have to borrow bitcoins in the future, though.
