The Cardano blockchain released its new node version v.1.35.6, which comes with functionality called Dynamic peer-to-peer (P2P) networking.
The upgrade is designed to ensure network uptime and stability and improve overall resilience – or the ability of a network to provide and maintain an acceptable level of service in the face of faults and challenges to normal operations.
There are two ways to configure a Cardano node – either as a block-producing node or as a relay node. A block-producing node is responsible for producing blocks on the blockchain, while a relay node communicates with other relays and broadcasts blocks from block-producing nodes.
Dynamic P2P enables bidirectional usage of each connection, simplifying communication and increasing network resilience against failures or malicious behavior.
Although available Cardano's main network, the dynamic P2P functionality will be tested over the next few weeks by the Cardano code maintainer IOG and the Cardano Foundation to ensure a smooth rollout.
