>What problem does web3 or decentralization fix? In some cases you can align incentives differently than with traditional solutions. For example with DEXs you can spread the profit and work (such as providing liquidity) to participants rather than a central operator. It's also easier to prove what mechanism of the operation can and cannot be changed as the code is right there and if you are trading you only have to trust them for just the one function call rather than for holding your funds in their hands longer like with traditional exchanges.
