Polkadot 2.0 will introduce the JAM chain, and DOT will become an important part of the JAM architecture

On March 13th, according to Polkaworld, the Polkadot 2.0 Foundation stated in a keynote speech that Polkadot 2.0 may not be released in stages, but rather all at once on a large scale. In Polkadot 2.0, a new paradigm will be introduced, namely the JAM chain, which will become the foundation of Polkadot and provide multi-core computing and support for hundreds of chains like Polkadot. DOT will become an important component of the JAM architecture. In the JAM architecture, Polkadot's governance mechanism will no longer directly control the issuance of tokens. Instead, this responsibility will be determined by the JAM protocol itself. This is a major change that could affect the governance and economic model of the Polkadot network.
