Multisignature, that is, multiple users to a digital signature of the same transaction, can be simply interpreted as a digital assets of multiple signature, such as Annie and Bob is a pair of lovers, they jointly managed 100 COINS, so they are one of them want to use the 100 bit, then you must need to two people agree to just can achieve,

Multiple signature technology, mainly used in security, in the original currency, to get the private key can be control account, this means that no matter who, as long as the private key, the COINS can dominate the public key name and less money doesn't matter, big account will have to have some protective measures,

For a safe, reliable system, immune to a single point of failure is very important, there are ways, first is to keep the private key into many pieces and separate custody, but this method of soil problems, is not convenient also is not very smart,

Later, on December 20, 2011, the currency of the core development team will add the function of multiple signature to the currency of the core code, in January 2012, the first multiple signature types of transactions appear on the block chain,

Will initially be the largest number of the private key limited to three, then it has 15 private key can be extended to support most, generate COINS multisignature address only need two steps, first determine the number of private key signature, second, determining transfer requires a few private key to sign is ok,

Wisdom Chain multisignature

Wisdom Chain of multiple signature function is an independent function, it is different from other block Chain technology, before trading broadcast to block Chain, do not need to rely on the application of centralized type signature compilation, all process is done on the block Chain, so don't have to worry about all of the applications or can account on the application of the centralized type server operation, can complete the signature, there is no fault on the function point, and that's what Wisdom Chain unique, is a very powerful feature,

In Wisdom Chain, support pattern is MN, this means that a rule there can be a maximum M signatures, but at the same time can have N signature to the signature (please note that the N must be less than or equal to M),


(above is multisignature rule definition)

Other block Chain technology is usually signed by a third party to provide multiple services, but in Wisdom on the Chain is as a standard feature, this to want to realize the automation of multiple signature function programmer, also means that the user can through the interface can realize multiple signature function,

In addition, multiple signature function itself can be a trigger to implement other transactions or events, such as; Online wallet, common property/partnerships, supervision and administration/equity weighting, digital heritage, such as the issuance and payment is one of the very good example, generally speaking, in the process of issuance and payment have been accompanied by the following projects:

(1) the due date;
(2) (bonds) coupon rate;
(3) the principal or face value;
(4) regular servicing,

If using not through a third party involved in decentralized intelligent contracts, so in order to do the contract requires complex deep money, more in the process of decentralized instead, smart contracts may be unable to perform for the following disadvantages:

(1) enterprise cash is not hidden, because it goes against the original purpose of financing;
(2) in a bond secured and unable to fulfil his obligations, then almost can cause by selling assets or the result of the right to guarantee, therefore, it will inevitably have centralized type power intervention;
(3) contracts must also be paid to invoke, as the payment is through a centralized model of the subject - Banks to operate, so the intelligent degree of "smart" contract has certain limitations,

, Wisdom Chain approach is very simple: use Wisdom Chain asset definition used to represent debt and trade terms and conditions of the tokens, that is to say, as to a timestamp and certification operation (i.e., to generate the hash value and record on the block Chain) file to handle;

(1) centralized contract can automatically to the creditors' account for remittance and payment;
(2) the centralized securities exchange, to allow the bonds are traded between creditors;
(3) according to the application of bond tokens, multisignature, for trading platform, all the processing and settlement of bonds between the parties confirm,

As the right to exercise the process is very smooth and easy, also follows the necessary conditions of the real world, smart contracts expire (interest calculation, payment, management, and other conditions) itself in building management system of huge cost is a waste, for trading tokens, the specific purpose of trading platform is necessary, and it builds a, will be finished after can fully handle all the bonds and securities,

It is worth mentioning that in the Wisdom of Chain set and issue bonds with the need to spend time in less than five minutes,
