Read this article for a complete explanation.
What is a Multisignature Wallet?
Basic Definition
Multisignature Wallet, or usually abbreviated as Multisig, is a type of cryptocurrency wallet that requires digital signatures from several different parties to authorize and complete transactions.
In Multisig setup, at least two or more private keys are required to open the wallet and perform transactions.
Public and Private Key Concept
Every Multisignature Wallet has two types of keys: a public key and a private key.
Public keys are used to receive payments, while private keys are used to sign transactions and access funds in the wallet.

Explanation of Multisignature Wallet in Cryptocurrency
Improve Security
One of the main advantages of Multisignature Wallet is increased security.
By requiring more than one digital signature to make a transaction, Multisig reduces the risk of theft or fraud associated with using a single wallet.
Risk Management
Multisignature Wallet also helps in managing risks, especially for entities or organizations that manage crypto assets .
By having more than one party have to approve a transaction, Multisig allows for a more thorough and secure decision-making process.
How Multisignature Works
Determination of the Number of Signatures
First of all, Multisignature Wallet users must determine the number of signatures required to complete the transaction.
The required signatures can be two of three, three of five, or other configurations, depending on the user's needs and preferences.
Multisig Wallet Creation
Once the number of signatures is determined, a Multisignature Wallet is created by adding the public keys of each party involved in the wallet.
This public key ensures that each party has access to the wallet and can sign transactions.
Signing the Transaction
When someone wants to make a transaction using Multisig, that person must sign the transaction with their own private key.
Once the specified number of signatures is collected, the transaction is considered valid and can be executed.
Types of Multisignature Wallet
A multi-signature wallet or multi-signature wallet is a type of crypto wallet that requires more than one signature to validate transactions.
Multisignature provides an additional level of security because it requires approval from multiple parties before a transaction can be executed.
The following are several types of multisignature wallets in Indonesian:
2-of-2 Multisignature
In this type, two signatures from two different parties are required to carry out a transaction.
For example, if two people have access to a wallet, both must approve the transaction before it can be processed.
2-of-3 Multisignature
In this type, there are three public addresses involved, but only two of them are needed to validate the transaction.
This type of multisignature provides more flexibility in case one party loses access to the wallet.
3-of-3 Multisignature
Here, all three public addresses involved must sign the transaction to validate it.
This type of multisignature offers the highest level of security because it requires approval from all parties involved before a transaction can be carried out.
N-of-M Multisignature
This type allows to determine the minimum number of signatures required (N) out of the total possible signatures (M).
For example, 2-of-4 multisignature requires two signatures from the four public addresses involved.

How to Create a Multisignature Wallet
Creating a multisignature wallet involves several steps that include understanding what a multisignature wallet is, choosing the right platform or service, setting the desired configuration, and managing the private keys and public addresses involved.
Here is a step-by-step explanation of how to create a multisignature wallet:
1. Understanding of Multisignature Wallet
Before creating a multisignature wallet, it is important to understand the basic concepts. Multisignature wallet is a type of crypto wallet that requires more than one signature to validate transactions.
This means that instead of requiring just one private key to authorize a transaction, a multisignature wallet requires multiple private keys associated with multiple public addresses.
2. Choose the Right Platform or Service
There are various platforms or services that offer the ability to create multisignature wallets, either in the form of downloadable software or services that run online.
The choice depends on user preferences, security, and specific functionality needs.
Some examples of popular platforms for creating multisignature wallets are:
- Electrum: An open-source platform that supports multisignature wallets and various other types of crypto wallets.
- BitGo: An online service that allows the creation of multisignature wallets with various additional security options.
- Casa: Platform specializing in providing crypto security solutions, including multisignature wallets.
3. Multisignature Wallet configuration
After choosing the right platform or service, the next step is to configure the Multisignature wallet according to your needs.
This configuration in Multisignature involves determining the number of signatures required to validate a transaction (N), as well as the total number of possible signatures (M).
For example, a 2-of-3 configuration requires two signatures out of three possible.
In addition, users also need to select the type of cryptographic signature algorithm to be used, such as ECDSA (Elliptic Curve Digital Signature Algorithm) or RSA (Rivest-Shamir-Adleman), depending on the platform chosen.
4. Generate Private Key and Public Address
The next step is to generate the private key and public address that will be used in the multisignature wallet.
This private key will be used to sign transactions, while the public address will be used to receive payments.
The process of generating private keys and public addresses is usually carried out by the platform or service used and can be done automatically through the provided user interface.
5. Private Key Distribution
After the private key and public address are created, the next step is to distribute the private key to all parties involved in the multisignature wallet.
This private key distribution includes all parties necessary to validate transactions according to a predefined configuration.
Distribution of private keys should be done with great care and only to trusted parties.
The private key is the primary access key to funds in a wallet, and its loss or misuse can result in permanent loss of funds.
6. Use of Multisignature Wallet
Once all private keys are distributed and the multisignature wallet configuration is complete, the multisignature wallet is ready to use.
To carry out a transaction, all parties involved must sign the transaction according to the number of signatures required.
Once all signatures are obtained, the transaction can be sent to the blockchain network for processing.
The transaction will then be validated and recorded on the blockchain, and funds will be transferred according to the instructions set out in the transaction.
7. Management and Security
It is important to continue to manage and monitor multisignature wallets regularly.
Such monitoring needs to be thorough, involving careful management of private keys, monitoring transaction activity, and implementing additional security measures if necessary.
In addition, users must always update the software and maintain security from cyber threats that might threaten the security of multisignature wallets.
Advantages and Disadvantages of Multisignature Wallet
Multisignature wallets have a number of advantages and disadvantages that need to be considered before deciding whether to use them.
The following is an explanation of the advantages and disadvantages of using Multisignature Wallet:
Advantages of Multisignature Wallet
High Level of Security
One of the main advantages of using a multisignature wallet is its higher level of security compared to regular crypto wallets.
By requiring more than one signature to validate a transaction, the risk of illegal access or theft of funds is lower.
Shared Control
Multisignature wallets allow multiple parties to have joint control over funds in a wallet.
The controls in Multisignature Wallet are especially useful in situations such as corporate financial management , where multiple individuals or departments need to approve transactions before they are carried out.
Prevent Loss of Access
In the case of a single wallet, if the private key holder loses access, then the funds in the wallet may be lost permanently.
Thanks to multisignature wallets, losing one party's access will not automatically result in a loss of funds, as it still requires a signature from the other party to authorize the transaction.
Configuration Flexibility
Multisignature wallets offer flexibility in configuring the number of signatures required to validate transactions.
These configuration variants allow users to adjust the security level to their specific needs, such as 2-of-3, 3-of-5, or other configurations.
Better Auditability
By involving multiple parties in the signature process, multisignature wallets enable greater transparency and better auditability.
Every transaction must be accounted for by several parties, which can increase trust and accountability.
Disadvantages of Multisignature Wallet:
Complexity of Use
Using a multisignature wallet can be more complex than a regular crypto wallet.
These complexities include the careful organization of multisignature configurations, distribution of private keys, as well as coordination between the various parties involved in the signature process.
Dependence on Other Parties
Despite the added security, multisignature wallets also introduce a dependency on other parties to approve transactions.
This slows down the transaction process and makes it difficult in situations where the parties involved are difficult to contact or are inactive.
Additional cost
Some platforms or services that offer multisignature wallets may charge additional fees for this additional service.
Users need to consider these additional fees as part of the total cost of managing their crypto assets.
Access Recovery Difficulty
If one party loses access to their private key, the process of restoring access can be complicated.
Restoring access requires coordination between the remaining parties and may require complex recovery procedures, depending on the platform or service used.
Platform Limitations
Not all crypto platforms or services support multisignature wallets. These services may limit users' choices in choosing a platform that suits their needs.
By considering these advantages and disadvantages, users can make better decisions about whether a multisignature wallet suits their needs and preferences in managing crypto assets.
It is important to weigh the added security benefits against the additional complexity and dependencies that may occur when using a multisignature wallet.
Conclusion
Multisignature Wallet is an important tool in increasing security and managing risks in crypto asset management.
By requiring digital signatures from multiple parties, Multisig provides an additional layer of protection against theft or fraud, and allows users to better manage risk.
With a good understanding of the concept and workings of Multisignature Wallet, users can take appropriate steps to protect and secure their crypto assets in an increasingly complex and risky environment.
