Etherium Upgrade is almost done, here are the key improvements to expect.
Scalability:
Introduction of Proto-Danksharding to enhance transaction speed and volume, benefiting Layer 2 solutions on the Ethereum blockchain. The integration of temporary data storage "blobs" will significantly reduce gas costs, making transactions cheaper for Layer 2’s.
Security:
Implementation of EIP-6780 will finally depreciate the awful
self destruct function which has caused a number of exploits in smart contracts.
Cross-Chain Improvements:
Introduction of EIP-4788 to facilitate easier, more secure
cross-blockchain interactions, enhancing interoperability with Layer 2
solutions.
