As developers keep improving the ethereum blockchain, even though previous ethereum hard forks failed to solve the problem of high fees in the ethereum blockchain.
But with the new London fork proposal 1559 which will offer a new fee system that burned all transactions fees instead of miners determining the fees, this will remove more ethereum from circulation causing demand to rise because of scarcity which will ultimately lead to an increase in price and fewer transactions on the ethereum network.
What are your expectations from this and how it will affect the overall ethereum ecosystem?
Ethereum is a very complex system with many moving parts, which is being worked on by independent development teams. Coordinating their efforts and making sure that everything works flawlessly is not an easy task. When the security of a huge amount of money is at stake, haste will only harm, because a full transition to PoS takes so much time. But the output will be a bulletproof system, where even the failure of one or more clients will not affect the performance of the network.
I expect that with the launch of Ethereum 2.0. this system will be much more scalable, it means faster and cheaper.
