Solving problems is not so difficult for the team who are experts in blockchain networks, because they are very experienced in identifying problems in blockchain and then stringing them into main solutions to become new project concepts and even adding them to new blockchain networks, now there are many new projects with new networks such as Solana, Fantom, and others.
I believe what you say because everyone who has experience will certainly easily know where the problem is and which direction they need to fix, just not all project teams have the same experience in solving their problems in their network, so some of them also still need help from other parties or in the form of cooperation partners.
