Breaking News!! New Perspective: Ethereum is just a testnet! Polkadot's DOT is the future of Web3!!
As a PhD student in Computational Neuroscience, my viewpoint is that the tech stack built by Gavin Wood on Polkadot is unlike anything currently in the crypto space... DOT has created something very unique in the massive update of JAM. The improvements already implemented in DOT are agile core time and elastic wake-up, allowing developers and companies to purchase a month's worth of computing power at a fixed cost in one go. You can buy more computing power as needed or sell unused computing power to others. Fixed costs are absolutely a key factor for large companies, as opposed to having to pay gas for every transaction they want to make (which can become very expensive during high-capacity periods on-chain), and projects now know exactly how many computations they can do each month. There is also asynchronous support. Projects/Parachains can now independently submit blocks, significantly reducing latency.
Their last major upgrade was JAM (Joint Accumulation Machine). This will fundamentally address scalability and synchronization issues. Currently, the larger the chain, the worse the synchronization. But JAM will solve the problem by allowing projects/Parachains to accumulate their own blocks and state chains and submit these batches to the relay chain. This eliminates the constant back-and-forth dialogue for each block between the relay chain and Parachains. This also means that each Parachain can process blocks in parallel instead of waiting to be added to the relay chain state. This will greatly increase the throughput of the network. It is estimated that there are millions of TPS on the main chain, not a test network, nor a sidechain, but the main network itself. And there is more, but I will stop here.
The developer of Ethereum's Yellow Paper, Gay Wood, the mastermind behind EVM, called Ethereum his testnet, and he is not joking.
