In a traditional PKI system, new nodes joining the network must be manually configured with the existing PKI keys and certificates. With Blockchain, however, new nodes can join the network automatically and securely, without the need for manual configuration. This is because each node in a Blockchain network has a copy of the entire Blockchain, which contains all the information necessary to join the network. When a new node joins the network, it simply needs to download the Blockchain and verify it against the existing nodes.

Q: How does PKI work in blockchain?
A: PKI, or Public Key Infrastructure, is a system of cryptographic keys, digital certificates and other security mechanisms that are used to authenticate and authorize individuals and entities on a network. In the context of blockchain, PKI can be used to secure communications between nodes, verify the identity of users and transactions, and ensure the integrity of data.
Q: Is blockchain based on PKI?
A: No, blockchain is not based on PKI.
Q: How does PKI server work?
A: PKI servers work by storing digital certificates and public keys. These digital certificates and keys are used to authenticate users and devices, and to encrypt and decrypt data.
Q: How does the PKI works in public key systems?
A: In a public key system, each user has a pair of keys, a public key and a private key. The public key is available to anyone, while the private key is known only to the user.
When someone wants to send a message to a user, they use the public key to encrypt the message. The message can then only be decrypted by the user, using their private key. This ensures that only the intended recipient can read the message.
