According to the jointEthereum development team, the delay in the release of the Dencun security update was caused by disagreements that arose between the designers of the consensus level and execution level clients.
The level of consensus is critical toreaching an agreement in the network, since it ensures the synchronization of all nodes, and the execution layer is responsible for executing smart contracts and managing the state of the blockchain.
Dencun update is designed to improvesecurity at the stages of scaling Ethereum, in particular, through the use of Proto-Danksharding technology, which allows increasing network throughput to 100,000 transactions per second.
It was expected that after several monthsA collective effort involving more than 140,000 blockchain testers, the Dencun update will be rolled out by December 2023. However, internal disagreements prevented full testing, which led to the postponement of implementation to next year.
