Blockchain-Based Decentralized KYC Solutions
Blockchain-based decentralized KYC (Know Your Customer) solutions aim to store user data securely and transparently on the blockchain network, instead of a centralized authority, differing from traditional centralized KYC systems. These solutions are especially used in financial services, digital asset exchanges, and crypto projects. By offering advantages such as immutability, transparency, privacy, and security, blockchain can make KYC processes more efficient and secure.
How Does a Blockchain-Based Decentralized KYC Solution Work?
1. Collection of User Identity Data
The user applies by providing all necessary identity information (e.g., passport copy, ID card, proof of address, selfie) for the KYC process. This data is typically collected through a digital platform.
2. Data Encryption and Creation of Digital Identity
The user’s information is encrypted on a blockchain-based platform and a digital identity (data fingerprint) is created. The user’s identity information is combined with the hashing algorithm on the blockchain, making the data immutable.
3. Decentralized Verification Process
The user’s identity information is verified by multiple validators (e.g., banks, crypto exchanges, financial service providers). Each validator evaluates and approves the user according to their internal procedures. However, this verification process is entirely decentralized, meaning there is no single central authority storing the data.
4. Recorded on the Blockchain
After verification, the data is securely stored on the blockchain network. This ensures that the data is accessible only to the user and the verifying parties. Blockchain encrypts the user’s identity information, making it immutable and permanent.
5. Sharing of Identity Information and Access Permissions
The user can share their verified identity information only with authorized parties. Blockchain requires user approval for each transaction, ensuring the user’s privacy is protected. For example, a crypto exchange can verify the user directly from the blockchain without sharing the information, completing the KYC without disclosing details.
6. Transparency and Traceability
Every stage of the user identity data is traceable and transparently recorded on the blockchain. This ensures the identity verification process is always auditable, users have full access to their data, and any changes made to the system can be immediately tracked.

Example of a Blockchain-Based Decentralized KYC Solution:
Example: SelfKey
SelfKey is a blockchain-based decentralized KYC and identity verification platform. SelfKey encrypts users' identity information and records it on the blockchain, allowing users to share their data only with authorized service providers.
Identity Verification: The user uploads identity information (e.g., ID card, passport). This data is encrypted and turned into a blockchain record.
Approval and Verification: Institutions integrated with SelfKey (e.g., a bank or exchange) verify the encrypted identity data on the blockchain. The KYC process is carried out according to each institution’s specific rules.
Decentralization: The SelfKey platform does not have a central authority. The identity verification processes operate completely decentralized, ensuring the security of the data.
Advantages of Blockchain-Based Decentralized KYC Solutions:
1. Privacy and Security:
User data is stored in an encrypted, decentralized structure, reducing the likelihood of large-scale data breaches. Users share their identity information only with authorized parties.
2. Immutability and Transparency:
Each transaction recorded on the blockchain is immutable and visible, making the entire identity verification process auditable and traceable.
3. Faster and More Efficient KYC Process:
Decentralized KYC solutions allow users to verify their identity once, without having to repeatedly authenticate across multiple institutions.
4. Global Access and Compliance:
Blockchain-based KYC can be used globally, enabling digital identities to be verified without national limitations.
5. Cost Reduction:
Eliminating intermediaries between tools and validators for data sharing saves time and costs.
Conclusion:
Blockchain-based decentralized KYC solutions offer privacy, security, transparency, and efficiency, making them a significant alternative to traditional KYC processes. They allow users to manage their identity information securely, while the immutability and decentralization provided by blockchain make these solutions more robust and reliable.
