I got mine in today - they look great!

I did attempt a push using block cypher and you can see from the screenshots the transactions are valid for the amount and are also locked to a set block time as intended

Thanks Yogg!

Ok, my card unlocks in just a few blocks. However, I already broadcast it using blockcypher.

Strangely, it's accepted and shows the lock time as 622800...

Ok. https://www.blockchain.com/btc/tx/50b9d14f35394c23faf7c303d75111ba3d86c2f180fca1c78911b483725d10a2

Must have worked - 5 blocks in advance! Cheesy

Awaiting confirmation, then will peel/update.  Cry

Peeled and swept! Thanks so much Yogg! - Solid job, through and through! Cheesy

Hey owlcatz Smiley
Thanks for the test !! I'm glad it worked as planned.

Hah !
Yes, when making my tests I also noticed that blockcypher push transaction feature will accept the transaction even if non-final.

However, the bond works as expected : no miner will include the locked transaction into a block until it has properly matured;
if they did, that block would be rejected by the network since it includes an invalid transaction.



Yoggy..Sorry was thinking the lock up was a bit longer...But well done good sir! First time I’ve ever broadcasted to the network, or used a smart contact. Very fn cool and quite unique! I have all sorts of ideas how this could be used out in the “real world”...that is when we can all rejoin it!

Noticed the updated holograms. Those are super secure! Way harder to remove than any holo I’ve ever peeled. Great job! 

Will posts some pics shortly

Please, I'd absolutely LOVE to hear more about your ideas of how these can be used in the real world. Wink

 Cheesy We are over due for a chat, look forward to throwing them all at ya.

Btw I sent the .001  BTC back to your Yogg wallet listed on your profile (from another wallet, didn’t want to wait for confirm).  It’s better served going to your continued innovations with ColdKey. Can’t wait to see what’s up next!

Thanks so much Chibi for testing the Cryptobond. Smiley Very cool that it worked as well !
I wasn't around much these last days, as I don't come to the office anymore because lockdown but yeah a chat is long over due now.
I'll ping you soon. Smiley



We are currently making the first release of Cryptobonds ready for you soon. Smiley
I expect them to be available sometime during April but definetely May at the latest.

Thank you everyone !

I finally got a chance to test drive the Coldkey Cryptobond.
I used your big picture to test the error correction on the locked transaction: when I cover about 5% of the image with my hand, my phone can still scan it. That's good Smiley

I finally got a chance to test drive the Coldkey Cryptobond.

First, I love the concept.  As an uncle to several I can see giving these as gifts.



It is really as simple as following the step by step instructions printed directly on the Cryptobond. 

My locked transaction: 0200000000010120286afd0ba5cf5aa8186b3b25085808db028b518d1dff858777b3c7e97b385c0 000000000feffffff01a086010000000000160014c580f7e426632df79b4ea55dd4b1e578b3895d dc0247304402201bf313912f7201d0a61ff88ff708add6439cd1058b55d1d5d9f00646620c7d210 2200898f02a68fc457b8d0d474e6a1c9d51278de9173e96c65d9bfc7b265fc85c98012103be2db8 08a8cef4188bb411a2b1970014c90c15182ab9e7faf124100c9d14611f207f0900
   
I tried broadcasting before the locked block and it returned an error.  Once the block occurred I was able to successfully broadcast the locked transaction. 

The final step was to peel the hologram and sweep the private key.  The hologram has a clear film over it which required use of a razor knife to remove.  No way anyone is getting at the private key without it being very apparent.  I was able to then sweep the private key (qr code) into a Ballet Wallet cold storage card. 

Public address of the cryptobond:  https://www.smartbit.com.au/address/bc1qckq00epxvvkl0x6w54wafv090zecjhwuhklcuq

Really cool new product and very well executed.  There is definitely nothing like it available.

Hey Chibi Smiley

Well, it really depends on the pace of the new blocks that are found by BTC.

I'm glad that the testing went well !! Cheesy
Thank you very much for playing the game until the end. Smiley

Still not confirmed

Hey minerjones,

I think I know what happened here. Smiley

The block production was a bit slower than usual, this is why it took so long to reach the correct block height.
Anyway, it's passed now. The fee on the locked transaction was 5000 satoshis (~60sat/b) which is more than enough to include a transaction when BTC runs normally.

Can you please let us know how it went ? Were you able to sweep the locked funds ?



Just realized...my cryptobond is the first ever to be made and redeemed card made.  Cheesy

Yes, absolutely !
It is the first ever Cryptobond on a card that has matured and been redeemed. Smiley

Thank you sooo much Krogoth for going all the way through !!



Next cryptobonds to mature after mj's:

#622368   Lesbian Cow
#622512   ChiBitCTy
#622656   Sat0shisGhost

Current block height :
#622537

Lesbian Cow's and Sat0shisGhost ChiBitCTy's should have matured.
Sat0shisGhost's should be good tomorrow.



Given the worldwide situation, please stay safe first of all ... tests can wait.

We are still working on the release in the background. Smiley

Thank you everyone !

9 more to go !! Cheesy

Can't wait. This experiment is soooooo exciting !!
Thank you sir Mantis. Smiley

Please, when the public address will have received the funds, do redeem the Coldkey and sweep the funds to another address.
You can keep the BTC if you like. Smiley

Thanks !! Cheesy

Block 622080 has come and gone so I tried to submit again.

  This time the tx has sucessfully gone thru!

   [...]

   The btc addy that had a zero BTC balance now has a 0.001btc value on it! Cheesy

   Edit:  I also successfully swept the 0.001BTC from the private key into my Mycelium wallet as well   Cheesy

Hey Krogoth !

Thank you SO much for doing this test !
I imagine that going to the extend of actually redeeming the Coldkey wasn't easy for a recognized Collector such as yourself.
Many many thanks for playing by the rules until the end. Smiley



  So true...I wept with sadness when I peeled...not used to doing this at all as I collect em intact...but I had to do it for this time...next time I buy these...never shall they be peeled  Wink

I am very happy that everything unfolded as expected.  Cool
Funds were stucked, you were able to execute the smart-contract AND sweep the funds to another BTC address.
That's great Cheesy

The rest of test Cryptobonds should expire one day from each other from now on.

So much excitement !! Hah, thank you for everything.
This part of Bitcointalk definitely always brighten up my day no matter what. Smiley



Very cool! Thank you for sharing Krogo and good job Yogg!

Thank you for the kind words Mitchell. Smiley
Job is really only starting now that we know it works ...


Maybe a tester whose Cryptobond didn't expire yet can try to execute it ?

Thank you Smiley

 I received this special Cryptobond card and followed the instructions provided which were very easily understood

  I scanned the large QR code with a QR code reader and got the following...

  
Code:
020000000001011c9f640abbfe92fbdf932470c6c948ed8a6f7c98e57de0100000000feffffff01a086010000000000160014c5805a462bdf668db3cd2f2a3d15e8ee365e6a0b0247304402204017c33d14075ae92551336f1142e1679a06ffcd41d550931c131f1f5271d8ab0220694fd7d7822e9ee407d8f28734f5a001057c899ab66074395fd41b0f6e0121037ad70bc502c9260cf5deb4b6724dc445ffc8bcae2f407768bf5a662b587ad80a007e0900


I pushed it thru the https://www.blockchain.com/btc/pushtx and got the following result at block 622080 has not arrived yet
