Veritas Escrow Service / MultiSig m-of-n tx support [BTC/LTC/PPC/NVC/42]

[Serge V.]

     Greetings Community!
     I would like to offer You the most reliable escrow service based on bitcoin protocol – multi-signature transactions. Was found that existing such services are still complicated for most people, so I decide to help You with each step and use only standard wallet. You can choose 3-of-3 / 2-of-3 scheme with one escrow agent, or even 2-of-2 - without (!) any agents, actually, almost any (15 max) m-of-n, where m - is a number of required signatures (private keys) for releasing the funds and n - is a total number of involved people (public keys).

Main Features:

• No need to trust each other or any sites. Stop worrying about agent trust score! You can easy verify the correctness of MultiSig address and final transaction.
• Built-in protection from fraud, hacking and thermo-rectal cryptanalysis physical compromising. Nobody have access to the funds, including the escrow agent. Coins can be released from MultiSig address only when the buyer, the seller and the escrow agent checked and signed the correct transaction (voted).
• Protection from losing if one of the parties will disappear. When choosing 2-of-3 escrow scheme, two parties will be capable to release the funds without third party.
• Protection from disappearing of the agent. In case if something happen with me, you will be able to contact with the 2nd escrow agent to finalize the transaction (he will keep a copy of my key).
• Instant releasing of funds from the escrow. Are You still waiting for the escrow agent to come on-line and release Your funds? Choose 2-of-2 or 2-of-3 escrow scheme and do it without him!
• Reliable purchase/sell (also applicable for accounts) and loan with collateral escrow schemes.
• Encrypted communication. For easy and instant communication, we will use skype-alternative secure p2p messenger Tox (1). End-to-end encrypted messaging with ProtonMail (2). PGP key (3).
• Does not require any special knowledge. I will support You until escrow completed.
• No need to download the full transaction history and keep the wallet synchronized. You will need the full version of a client for creating MultiSig address and for signing the final transaction. For this purpose, You can use even offline wallet!
• BTC, LTC, PPC, NVC & 42 support. Depend of Your requests I will add more coins in the future.

  Below You will find in signed message my and 2nd agent Tox IDs and my pubkey. To verify this important data, open Your wallet application and go to File -> Verify message.

Notice. Before we start the escrow:
1.   Check that You have installed the latest version of the full BTC (LTC, PPC, NVC or 42) wallet application.
2.   If You would like to use Tox, please make backup of “tox_save.tox” file (located in Win 7-10: C:\Users\UserName\AppData\Roaming\Tox), it contain Your unique Tox User ID. I will not accept Tox ID change during the escrow process.
3.   The current FEE for the MultiSig escrow is 1% but not less than 0.005 BTC (or equivalent) and 0% for the regular escrow (sum under 0.5 BTC).

Caution! Stay away from such knows "MultiSig escrow services" that generate address only from own keys, this is not safe, because full responsibility of Your funds lay on the service. Only with the escrow agent, that generates MultiSig address from your public keys, You don't need to trust to the third party!

So you mean, both escrow agents are yourself and you'd essentially have complete control of the 2-of-3 transaction?

I am not associated with the 2nd agent in any way, we live very far from each other. He will need only if something happen with me or dispute situation. If You don't want to trust him, You can propose Your 2nd agent or choose another escrow scheme (3-of-3 or 2-of-3, etc.).

P.S. Also he will replace me when I'm offline (I can't be online 24/7), in this case I will play the role of the 2nd agent.



Nobody can't have complete control of 2-of-3 transaction, 2-of-3 means that for releasing the funds from MultiSig address is required 2 of 3 signatures - one from the escrow agent and the other from the buyer or the seller. Complete control of the transaction always has usual escrow agent.

if you "know" where "he" lives then you are somehow associated with him. What would stop you from colluding with one party and releasing the funds to that party inappropriately?

I can propose You 3-of-3 (with one escrow agent) or 3-of-4 (with your 2nd agent) escrow scheme - this will protect "from colluding with one party and releasing the funds" in 100%.

[Serge V.]

Do not miss! Be the one of the first 3 clients who will get lifetime free escrow service. Proposition actual until February 01, 2015.

[Serge V.]

No use in multisig if 2 of the 3 parties (the escrows) are not trusted.

Dear users, in the role of the 2nd escrow agent can be anybody you trust, he will need for additional safety of Your funds, for releasing the coins (I will instruct how) in case if something happen with the 1st agent and when You can't contact with him (or dispute situation). If You don't need additional level of security, choose 2-of-3 scheme (with one escrow).


Anyway, one trusted usual escrow agent is not better than 2 untrusted MultiSig escrow agents.

Sorry but this is much more complicated than usual escrow services imo.

Only 3 commands in bitcoin/litecoin-qt console for the end user. This will give absolute security for paranoid clients with round sum. For small tx or for those people who trust me, I can propose usual escrow service.

[Serge V.]

Actually, with MultiSig, some kind of escrow possible and without third party (I can help to prepare transaction).

Let me quote Satoshi about 2-of-2 escrow transactions:

The basic escrow: The buyer commits a payment to escrow. The seller receives a transaction with the money in escrow, but he can't spend it until the buyer unlocks it... If the seller doesn't send the goods, he doesn't get paid. The buyer would still be out the money, but at least the seller has no monetary motivation to stiff him.

The buyer can't benefit by failing to pay. He can't get the escrow money back. He can't fail to pay due to lack of funds. The seller can see that the funds are committed to his key and can't be sent to anyone else...

your newbie and want to make escrow?

Sorry but this is much more complicated than usual escrow services imo.

Exactly. Using a standard well trusted escrow agent is much easier. Even if it is multisig I think you should have more trust here before starting this service.

[Serge V.]

your newbie and want to make escrow?

How do You think, can newbie perform MultiSig escrow (or show me who provide such service)? I started this thread with aim to show the people that with MultiSig transactions they don't need to trust anybody, bitcoin protocol gives more higher level of security than can provide any trusted escrow.

[Serge V.]

Exactly. Using a standard well trusted escrow agent is much easier...

Easier. MultiSig for those, who likes always keep under control own money.
