  • Governments in many countries want to be part of the growing virtual currency trend. By replacing hard-to-track cash with state-issued digital money, governments can more easily find out who is buying what from whom. That could help catch tax cheats and fraudsters, creating more government revenue that can be spent for the public good, and shake up how government technocrats track economic growth and inflation. But depending on how a sovereign digital currency was designed, it could also give the state a powerful new tool to help it spy on citizens. For some governments, that's not a bug, it's a feature, noted GZEROMedia.

  • Blockchain can help strengthen trust in those who record or verify with trust in a decentralised network secured through cryptography. IBM’s Food Trust was one of the first production enterprise blockchain systems (with Walmart). The French grocery chain Carrefour recently announced that fruits and vegetables whose provenance is tracked through the system sell better.

  • Vault Platform is a blockchain-based tool that enables employees to securely capture and report harassment. The app is designed to create a time-stamped, tamper-proof record of the incident in question. The reports can either be stored privately on a user’s phone, or shared with an employer. Trend Watching believes that the most striking feature of the app is its ‘GoTogether’ feature. This alerts employees if other people have recorded incidents relating to the same individual, and using a ‘blind network’ enables them to collectively share their reports with their employer while preserving their anonymity from each other.

  • Blockchain is being used to bring new levels of trust and transparency to various activities, according to Trend Watching: Agora’s voting system transformed Sierra Leone’s elections, the first blockchain university is upending how higher education has typically worked, while consumers can monitor their chickens in China to make sure they’re truly free-range.
  • Bitcoin is on track to consume 0.5% of the world’s electricity this year, claimed Quartz. That’s about as much as the Netherlands; meanwhile, the energy footprint for mining cryptocurrencies is doubling every six months.

  • Some of the biggest banks, along with technology companies and other firms are making significant investments in research and development to see how they can harness blockchain. These efforts could transform many aspects of business, including how we think about security. Historically, the mainstream cybersecurity philosophy was to build a perimeter wall to keep out intruders. Blockchains could make the perimeter irrelevant by ensuring the integrity of a given network. It is akin to securing the metaphorical veins and arteries of the digital world in order to ensure the health of the body that is the network. 
  • Blockchains, once developed, have the potential to be a powerful solution to many of the security problems faced by financial institutions, argued PwC. The transaction-level cryptographic control associated with blockchains could also extend to manufacturing, pharmaceuticals, the transportation industry, or any sector that makes important products that need to be secure. Blockchain-based technologies at some point could eventually become the backbone for all collaboration and communication that needs to take place in these industries.
