The 3rd Week, April

Patract had participated in the discussion about the Polkadot Alliance Pact in the Polkadot Direction group. The Pact believes that because Polkadot is a project driven by governance such as councillors and referenda, it is not completely controlled by static code logic and needs to maintain the interests for token holders. Therefore, Proper management of the community should not allow unethical fork projects to appear arbitrarily, such as trying to build a bridge to access in the Polkadot ecosystem, or even defrauding the Treasury or Grant for fund.

The community is facing with complex and diversified ecological projects. Considering the community can’t quickly distinguish between good and bad, multiple relay chains may appear in the community, resulting the ecosystem into a fragmented direction, which is greatly detrimental to the long-term development of the Polkadot community and Web 3.0 vision. Some Councillors believes that for decentralized blockchain projects and open source community culture, it is impossible to build a wall of friends or enemies, or to limit the convention to basic principles. Such issues should not be raised to the political level and at the referendum level, it will hinder possible innovation.
