In early March, Polkadot’s annual developer conference, sub0 Asia, officially concluded in Bangkok, Thailand, and in the face of fierce competition in the blockchain industry, Polkadot founder Gavin Wood revealed in his speech that the much-anticipated Polkadot 2.0 will probably be rolled out on a large scale in one go, rather than in phases, a news that has undoubtedly pushed Polkadot into the limelight.At the conference, Gavin Wood presented the world with an ambitious vision for Polkadot 2.0, which will be built on a new paradigm called the “JAM Chain”, which will provide Polkadot with powerful multi-core computational power to support the efficient functioning of hundreds of chains, and a JAM architecture in which the DOT, Polkadot’s native token, is given the status of a “First Class Citizen”, connecting Polkadot to the JAM and taking part in the JAM’s functioning and governance, and where the JAM protocol takes over the rights to issue tokens, a major change that is sure to impact the governance and economic model of Polkadot’s network.
