Polkadot founder Gavin Wood has proposed a revamp of the network's resource allocation system, called Polkadot 2.0, which would create a network of sovereign chains connected by "accords." The current system of auctioning off parachain slots has been problematic, but Wood's proposed framework would allocate "core time" via a marketplace, represented by NFTs. Wood's new vision for Polkadot is "application centric, not chain centric," and would address the biggest drawbacks of Polkadot 1.0, allowing for more seamless integration of apps across chains. However, deploying on Polkadot is more challenging than deploying on Ethereum or an L-2 due to its heavy-duty nature.
