Pillars of Self-Sovereign Identity
SSI operates on three fundamental pillars: Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), and Blockchain.
- Decentralized Identifiers (DIDs): A user-specific identification number linked to a single central authority provides control and privacy over personal information and allows individuals to utilize their digital identities in a variety of situations without disclosing unneeded personal information.
- VCs, or Verifiable Credentials: Digital certificates testify to a user’s identity or other qualities and allow people to only share the information they need to provide, respecting their privacy.
- Blockchain: Ensure that digital identification information is safe and unchangeable.
Blockchain, Self-sovereign Identity and Digital Credentials
A decentralized, secure ledger that is open to many parties is blockchain. It keeps track of all computer network transactions, and once data has been stored, it cannot be altered or removed. Consensus methods and cryptographic techniques—which call for agreement among network users—are used to accomplish this security. The network keeps the ledger up to date and uses consensus to confirm transactions, preserving the accuracy of the data.
In this article, we will discuss What is SSI, Digital credentials, and how they used blockchain technology extensively.
