Smart contract
Smart contract - blockchain technology
Smart contracts are digital contracts written on a blockchain basis, which can be automated and allow parties to exchange virtual assets, services, stocks, etc. transparent way without the need for intermediaries or intermediary services.
Since it's a pre-installed program, smart deals can do everything themselves when the conditions are met. For example, if you rent my apartment and pay with a virtual currency, you will receive an online bill of lading indicating that only when you send money will I give you the unlock code. So, if I or you send a key or money before the date of the contract, the contract will automatically retain the key / money and transfer to the two parties on the date of appointment. Once everything is done, the contract will go away, and the code itself can not be modified by any other party. Intelligent contracts can be used in all services such as insurance, payment, debt financing, legal ... Large deals with bills of lading, papers and arbitration Prolonged management can be completely lost with automatic contracts in the future.
Decentralized cloud computing
Decentralized cloud computing - blockchain technology
Storj, a startup from Atlanta Tech Village, has begun to emerge from the middle of the year with its business model never before seen: Airbnb of the cloud.
Storj says that the cloud storage model of the big servers of Google, Amazon, Microsoft, Dropbox, and others are expensive, obsolete, and insecure. As the data is concentrated at the servers of these companies, you risk losing your data if your server is hacked. What happens if you can store cheap, high-speed data in the redundant "repositories" of the computers globally safely?
Based on blockchain technology, this startup provides a platform for users to make money by leveraging extra hard drive space and bandwidth and "selling" them to parties in need. In return, cloud tenants are also entitled to services that are not only cheaper, but also more secure and have faster download speeds. The reason is that the files will be encrypted (only new ones have open source code) and split into several pieces to scatter into the repositories of different "hosts"; No individual or company can access the entire file or control the download. Completely downloaded files from different repositories should speed up; It will also be merged from the original piece when downloaded from the cloud. With a commitment to download speeds up to 10 times faster and cost only 50% of cloud services, Storj has attracted 18,000 users and raised $ 30 million through the issuance of STORJ virtual currency via Initial Coin Offering (ICO).
Micro grid system
We are familiar with the traditional grid leading energy from hydropower plants, thermal power, ... in residential areas. However, this grid system is at risk in the event of storms, floods, earthquakes, etc., and power lines are cut off.
Brooklyn Microgrid (BMG), a grid-start smart grid project implemented in Brooklyn, New York, is experimenting with a very interesting solution: setting up micro-grids with clean energy generated. in the residential area of your residence.
BMG microbial grid system - blockchain technology
BMG micro grid system model
To do this, BMG mobilizes households to use solar panels but does not consume all of the electricity they emit (especially in the summer), turning away the excess energy they accumulate. a micro-grid to sell to households in the region through a blockchain platform. Households wishing to use cheap clean energy but do not have the option of installing solar cells can choose to buy electricity from the households with this excess electricity.
This is done very quickly through a smartphone application that allows you to schedule the amount of electricity you can pay and "bid" the vendor. BMG's blockchain meter will also help them pay their bills automatically and transparently.
As a result, when joining the BMG grid, households have the choice of either power supply (from the micro grid or traditional grid), budget management as well as availability of backup power in the area. when disaster strikes.
Applications such as the micro-grid also once again reinforce the potential for break-up of the shared economy - a model that Uber and Airbnb pride themselves on can now be applied to unmatched services. come.
Other applications
In addition to intelligent contracts, cloud computing, capital mobilization, etc., blockchain is also used in many areas such as online voting (pioneered by the Liberal Alliance of Denmark with the first blockchain voting system on the world), asset management and supply chain
