Had no problems on sending, just hard to find the faucet site.
Somehow bitaps always rejects my tbtc requests with an "undefined" error message, why?

Everyone, If you find it difficult to get the $TBTC, you can try from http://bitcoinfaucet.uo1.net/, because of the entire list that I tried on this forum, almost all of them didn't work except the ones I mentioned. And when you're finished with the test, don't forget to return it to address they provide, you're not the only one who needs $TBTC.

If I understood you in correct way, one of  the possible  reasoning  for their   "undefined"-error-message could be that your transaction didn't arrive to bitaps nodes at the time you requested them. The testnet is not so rich with nodes as the mainnet and the latency in transaction propagation should matter.

I am tried minimum 2 of 2

Very difficult to get TBTC tokens I think more than 10 webites I tried to get faucet but I did not get but when I used this website https://faucet.triangleplatform.com/bitcoin/testnet I easily got 0.1 testnet mbtc.

Thanks brother for sharing this sites I try first time then easily I  claimed faucet tokens

Multisig Wallet really very interesting and fully secure method for using and saving wallet and this was my first time for using this multisig wallet and I took 2 of 2 wallet testnet. I did face some problem when I sent some testnet bitcoin then electrum wallet gave error of lower output I tried again this time I faced no problem and everything was going well.

Here is my TXN ID: 44f38ce33a833b3dc67f8a7e26643a5dcacba693f32955b15d191be0c78a6a0c

My small review:

There are many versions of electrum wallet are available in download website like Linus, window and android etc i have laptop with window then I used window version. After downloading, I converted mainnet to Testnet use of "--testnet". For multisig wallet, I used two different devices and create 2-of-2 wallet and added cosigner key in alternate account. Finally, I deposit some testnet funds and do sent transaction.

This transaction has been already merited:

How it comes that both of you, Nalain420 and hafiztalha, have the same transaction? Are you alts or cheating me?  Take into account, that  I, as  DT2 member, can set a negative trust to your account for the attempt of cheating.

UPD.

After pondering a bit on this situation I have came to conclusion that Nalain420 and hafiztalha, more likely than not, are alts of the same person who sent two different transactions (44f38ce33a833b3dc67f8a7e26643a5dcacba693f32955b15d191be0c78a6a0c  and 18f9336d7dcebd728ecdca68c7a5a4b67d8557b6cd682b38eb0bd7baf1c50c4f) to my address from the same wallet but mixed their txids.

Thus, as Nalain420 has been already merited (I regret of this)

hafiztalha is not eligible to this challenge any more.

Excuse of copied txid

I just copy transaction id of previous user Nalain420 and check on explorer for seeing that my transaction will be okay or not

is not acceptable.

Sorry for that now I am updated my real transaction id

Actually, I do not have much knowledge about this multisig wallet I just copy transaction id of previous user Nalain420 and check on explorer for seeing that my transaction will be okay or not

Mistakenly, I submitted copied nalain420 transaction id

My real transaction id is 18f9336d7dcebd728ecdca68c7a5a4b67d8557b6cd682b38eb0bd7baf1c50c4f

It was a bit of a struggle and I had to look at the guide a few times because it was my first time sending multisig but it was very interesting and a new knowledge for me because after all it will be very useful. I think I did well for the first try but if there are any mistakes please correct me.

[Woodie]

I love me a great Challenge and this one is worth giving a try  

Am familiar with multisigs on other chains but not much with bitcoin which is why I couldn't pass this experience the second I saw this challenge...and I don't expect the process to be any different either!

So this was a one-man job, with 2 devices acting as user1 and user2 and because I was limited with the number of free devices, a 2-of-2 multisig was my best option using electrum Wallet as this is a popular brand based on my wild guess. And having used this wallet several times, it was a little confusing when I got on the mobile version because by default this runs on the mainnet network but after switching to the desktop version in testnet mode its straightforward & nothing complicated of course...

It's a bit difficult to find a BTC test net balance at the moment, even the website I subscribe to is now out of stock.
Finally I got the balance from tatum io, yes this is very important for our test net needs.

Thanks @satscraper to the challenges held, I think everyone has become more active in trying out some of the good features that BTC can do, including this multisig challenge. I'm sure many people will learn new things from this challenge.

[satscraper]

It emerged that challenge has attracted plenty of folk.

During the  past two days 19 ppl completed the task and got  95  merits (in sum) from me. This overrun my merit  pool. I'm not a merit source, thus I have to postpone this challenge and  refill my pool to go on  in this thread. The small  merit surplus I have is intended  to be used for  similar challenge on local board.

With this being said, the thread is temporally closed (presumably for a month).


It seems I have encountered the cheating attempt.

To prevent it in the future (at resuming this challenge) I have to change it's rules: from now on it is opened solely for Senior+ accounts. Presumably,  the award will be   lowed to 4 merits.

[satscraper]

Challenge is opened now  with a couple rules altered:

Changed:

• Opened solely for Senior+, except the negative-trust and alt accounts.
• Tell a little bit  of your   multisig wallet in this thread using the following template:
  Type of multisig:
  Wallet's coordinator:
  1st cosigner:
  2nd cosigner:
  3rd cosigner (if any):
  and so on:
  
• 2 merits appraisal

Example:

Type of multisig: 2-of-3
Wallet's coordinator: Sparrow
1st cosigner: Passport 2
2nd cosigner: SeedSigner
3rd cosigner: Jade

[Unknown Op]

Type of Multisig: 2-of-2
Wallet's Coordinator: Electrum
First cosigner: Myself
Second cosigner: also myself
Transaction hash: 271ad45d87a1ea93d4d095b02a6093c2581b2b2d05d90906c8b8ffd9a0f04fcd

Hope I have done everything correctly and also special thanks for sharing details how to perform this transaction.

I really enjoyed to make this multisig transaction. I learned a lot about how multisig works and this one is best method for secure transaction. I did not encounter any problems while doing this and just a little wait in claim bitcoin testnet faucet.

Anyways, thanks for organising this amazing challenge.

Almost correctly as you didn't explain what "myself" means.

And  the the second comment. The point of using multisig for storage your stash is that it eliminates the threat coming from  your might be compromised keys generated by single software/hardware wallet thus cosigners must be different in a sense that they must be relevant to distinctive software/hardware  wallets (and  machines running those software).

Your case forced me to add some alteration to the rules of this challenge.

Changed:

• Cosigners must be relevant to the different software/hardware  wallets (and  machines running those software).
• Cosigners must be described with an unambiguous clarity

[punk.zink]

Type of multisig: 2-of-2
Wallet's coordinator: Bitcoin Core V26.0
1st cosigner: Bitcoin Core Client at Machine 1 (Personal Computer with i5 processor)
2nd cosigner: Bitcoin Core Client at Machine 2 (Asus Laptop)
TXID e6a17bc2c4854226f718b6f37868b9e39edd7bf58c09a0d474c44f62f7bde981

If you check the transaction using https://mempool.space/testnet then you will not get the Multisig tag on the transaction as you can find in P2SH or P2WSH Multisig transactions. However, by looking at the P2TR tapscript on the transaction, you will be able to find out whether the transaction is indeed a Multisig or just the standard one.

Taproot 2-of-2 Multisig Transaction will have the script <PK1> OP_CHECKSIG <PK2> OP_CHECKSIGADD OP_2 OP_NUMEQUAL

Making Multisig transactions may be a new lesson for those who have never done it before but creating a Taproot Multisig transaction is a completely different experience

Frankly, the approach you have used is beyond my expectation. That is why you have got one merit more.

Did you use a taproot-compatible script to build the relevant descriptor and import the latter into your Botcoin Core v 26.0? At least, I would follow this path to create taproot multisig transaction using two other keys as cosigners.

If my guess is correct, wouldn't you mind to  share your descriptor here , sure, in its general form?

To import Taproot Multisig Address 2-of-2 into Bitcoin Core all you need are 3 Descriptors wallet. 2 Descriptors as Cosigners 1 and Cosigners 2, while 1 other Descriptor as Internal Key. You can also use the Unspendable Key as an Internal Key (eg. 50929b74c1a04954b78b4b6035e97a5e078a5a0f28ec96d547bfee9ace803ac0 from BIP341), so for the output spending script it only depends on the script path (multisig script). If the Internal Key is spendable, then you can also create a spendable P2TR keypath using the Internal Key.

If you want to get a change (multisig) address for every transaction made, then you have to import the Descriptor at both external (receive) and internal (change) path levels. Hence the checksum at external path and internal path must be obtained first through getdescriptorinfo.

To get the checksum on the external path descriptor, the arguments and expressions that should be used:

Code:

getdescriptorinfo "tr(XPub1/0/*,sortedmulti_a(2,XPub2/0/*,XPub3/0/*))"

and for the internal path descriptor:

Code:

getdescriptorinfo "tr(XPub1/1/*,sortedmulti_a(2,XPub_2/1/*,XPub3/1/*))"

After the checksum of each external path descriptor and internal path descriptor is known, all that remains is to create a blank descriptor wallet with the private key disabled. Then import the taproot multisig descriptor to this blank descriptor wallet.

Code:

importdescriptors '[{ "desc": "tr(XPub1/0/*,sortedmulti_a(2,XPub2/0/*,XPub3/0/*))#checksum", "active": true, "timestamp": "now", "internal": false },{ "desc": "tr(XPub1/1/*,sortedmulti_a(2,XPub_2/1/*,XPub3/1/*))#checksum", "active": true, "timestamp": "now", "internal": true }]'

Lastly, all you have to do is create a new taproot multisig address:

Code:

getnewaddress "label" "bech32m"
