Blockchain technology is an emerging technology that various sectors are adopting in innovative ways.
Energy: energy companies are using blockchain technology to create peer-to-peer energy trading platforms and optimize access to renewable energy. For example, let’s look at these uses:
Energy companies using blockchain technology created a trading platform for peer-to-peer electricity sales. Homeowners with solar panels use this platform to sell their excess solar power to neighbors. The process is largely automated: smart meters generate the transactions and the blockchain records them.
With crowdfunding initiatives based on blockchain technology, users can finance and purchase solar panels in communities that lack access to energy. Backers could also receive rent from these communities once the solar panels are built.
Finance: traditional financial systems, such as banks and stock exchanges, use blockchain services to manage online payments, accounts and market transactions. 
Multimedia content and entertainment: Multimedia content and entertainment companies use blockchain systems to manage copyright data. Verification of royalties is critical for artists to receive fair remuneration. Several transactions are required to record the sale or transfer of copyrighted content. 
Retail: retail companies use blockchain technology to track the movement of goods between suppliers and buyers.
