Critical Thinking Response:
Polkadot’s approach allows for multiple currencies/blockchains to operate together and share transactions through its hub technology.
A platform like ChainReintegrate opens up avenues for people who are reintegrating to earn rewards, credits, tokens toward educational and employment opportunities across various vendors/agencies/currencies.
Factors that would be crucial to a reintegration platform on Polkadot would include security, privacy of personal information, access to ALL those who wish to use the platform, credibility, and getting vendors/agencies to participate and use the platform.
