According to Tiger Research, India's Ministry of Electronics and Information Technology (MeitY) announced the National Blockchain Framework (NBF) on September 4. India's national blockchain framework has adopted a different approach from existing public blockchains. Adopting permissioned blockchains instead of public blockchains such as Bitcoin or Ethereum. In this model, only authorized participants can verify transactions, making it more suitable for government services. This is because the protection and control of personal information has been strengthened. The key keywords of the national blockchain framework announced this time are security, transparency, and increased trust. By establishing a blockchain infrastructure that will become the foundation of the national system, companies can develop blockchain solutions suitable for the public sector.
