  The emergence of big data and Artificial Intelligence (AI) technology is
reshaping the world. While the technological revolution improves the quality of
our life, new concerns are triggered. The superhuman capability enables AI to
outperform human workers in many data- and/or computing-intensive tasks. Also,
digital superpowers are showing arrogance towards individuals, which erodes the
trust foundation of the society. In this position paper, we suggest to
construct trustworthy and safe communities based on a BLockchain-Enabled Social
credits System (BLESS) that rewards the residents who commit in socially
beneficial activities. Human being's true value lies in serving other people.
The BLESS system is considered as an efficient approach to promote the value
and dignity in efforts focused on enhancing our communities and regulating
business and private behaviors. The BLESS system leverages the decentralized
architecture of the blockchain network, which not only allows grassroots
individuals to participate rating process of a social credit system (SCS), but
also provides tamper proof of transaction data in the trustless network
environment. The anonymity in blockchain records also protects individuals from
being targeted in the fight against powerful enterprises. Smart contract
enabled authentication and authorization strategy prevents any unauthorized
entity from accessing the credit system. The BLESS scheme is promising to offer
a secure, transparent and decentralized SCS.
