== Concept ==

In actual case, the blockchain essentially has no querying abilities when compared to [[database|traditional database]] and with a doubling of [[Node (networking)|nodes]], network traffic quadruples with no improvement in throughput, latency, or capacity.<ref name=":2">{{cite arxivbook|last1=Raikwar|first1=Mayank|last2=Gligoroski|first2=Danilo|last3=Velinov|first3=Goran|date=2020-03-12|title=2020 Seventh International Conference on Software Defined Systems (SDS)|chapter=Trends in Development of Databases and Blockchain|pages=1177–182|classdoi=cs10.DC1109/SDS49854.2020.9143893|eprintarxiv=2003.05687|isbn=978-1-7281-7219-4|s2cid=212675742 }}</ref> To overcome these shortcomings, taking a [[database|traditional database]] and adding blockchain features to it sounds more feasible.<ref>{{Cite web |last=Anadiotis |first=George |title=How to use blockchain to build a database solution |url=https://www.zdnet.com/article/blockchains-in-the-database-world-what-for-and-how/|title=How to use blockchain to build a database solution|last=Anadiotis|first=George|website=ZDNet|language=en|access-date=2020-03-27 |website=[[ZDNet]] |language=en}}</ref> That's how the concept of Blockchainblockchain-based database came into existence, which consists of multiple member clouds riding on two primary layers,; the first one is ''Database Interface'' and the second one is the ''Blockchain Anchoring''.<ref name=":0" /> The idea behind the blockchain based database concept is to complement the functionality and features of [[Relational database|SQL]] and [[NoSQL]] databases with blockchain properties: data immutability, integrity assurance, decentralized control, [[Byzantine fault|Byzantine fault tolerance]] and transaction traceability.<ref>{{Cite book |chapter-url=https://www.researchgate.net/publication/318131748 |year=2017 |language=en |doi=10.1109/BigDataCongress.2017.85|last1=Zheng |first1=Zibin |last2=Xie |first2=Shaoan |last3=Dai |first3=Hongning |last4=Chen |first4=Xiangping |last5=Wang |first5=Huaimin |title=2017 IEEE International Congress on Big Data (BigData Congress) |chapter=An Overview of Blockchain Technology: Architecture, Consensus, and Future Trends |pages=557–564 |isbn=978-1-5386-1996-4 |s2cid=29591273 }}</ref>

== Blockchain Future ==

Now you must have understood what is Blockchain usefulness and how it can be used in all our works. Our thinking about this information has been changed by changing how and where information can be stored, who can access this information and what can we do with this information.

Which is the main reason that some organizations are against it because how the blockchain organizes the information and how to maintain our records-keeping infrastructure goes to the heart of these things. It is clear from this that people will not accept Blocakchain technology so easily and it is not going to come overnight because it challenges traditional technology at every step.<ref>{{cite web|url=https://zeecourse.com/what-is-blockchain/|title=What is Blockchain |publisher=Surajraje |date=15 May 2021|access-date=15 May 2021}}</ref>
