Heartbeat mechanism
If a node goes offline and does not reconnect within the specified time , the heartbeat number will change to 0, and the node information will be deleted
Steps：
The node reduces the heartbeat countof all known nodes by 1 and sends a ping request.
When the receiving node successfully receives the ping request, it resets the heartbeat of the sending node’s heartbeat count and sends a pong request.
When the sending node successfully receives the pong request, it resets the receiving node's heartbeat count and updates its node information.
Block height change notification
Step:
When the node height changes, it sends its own node height to other connected nodes. The receiving node processes the change request and updates the block height of the corresponding node.
Transformers uses the various mechanisms introduced above to ensure that the network status of each node in the network is good, ensuring the consistency of the data status of each node, and providing guarantee for the security and success rate of Transformers's continuous and rapid transactions.
Transformers Secure
Transformers adopts algorithms and security mechanisms that are widely used and have been widely tested in practice to protect the security of assets on the chain. Mainly including: ED25519 Conic Curve Signature Algorithm and Verifiable Random Function (VRF)
RSA(Rivest-Shamir-Adleman)
The RSA algorithm is an asymmetric encryption algorithm proposed by Ron Rivest, Adi Shamir, and Leonard Adleman in 1978. It is widely used in the field of public key cryptography due to the difficulty of factorization of large numbers. The RSA algorithm is mainly used in scenarios such as encryption, decryption, digital signature, and signature verification.
However, the RSA algorithm involves modular exponentiation of large integers and has a high computational complexity, resulting in relatively slow encryption and decryption speeds. To ensure security, RSA algorithms typically require longer keys (such as 2048 bits or longer), which can result in significant overhead in key management and transmission.
