The firist work on cryptographic secured chain of block was described in1991 by staurt haber and w.scott stornetta. The firist blockchain was conceptualized by aperson or group of people known as satoshi nakamoto The following year for nakamoto as core component ofcryptocurrency Bitcoin are served as public ledger for all transaction on the network Blockchain technology History
In augest 2014 the bitcoin file sizes ,containg record of all transaction cost that have occured on the network reached 20GB in january 2015 the size changed to 30GB frome january 2016 to 2017 grew from 50GB to 100GB The word block and chain used separetly in satoshi nakamoto originally paper but were eventualy popularized as asingle word blockchain by 2016 Blockchain explained
The blockchain is simply yet ingenious way of passing informetion from A to B in fully autometed and safe manner Falsifiying the single record would mean falsifying the enter chain in million of instance that is virtualy impossible Bitcoin uses this model for monetery transaction but it can be deployed in money otherway Blockchain explained
Decenteralization Trancparency immutability Three pillars of blockchain technology
If you wanted to interact with your freind then you can In decenteralizetion system the informetion is not stored by single entity in fact every one in the network own the informetion do so directly with out going third party This is what the main ideology of bitcoin 1.Decenteralization
One of the most interesting and misunderstood concept in blockchain technology is trancparency Aperson identity is hidden via complex cryptography is reperesented by only public sddress Then persons real identity is secure he reperesented by public dd ress 2.Trancparency
Immutability in context of blockchain means that once some thing entered into blockchain it cannot be tampered The reason is why the block chain gets this property is that of crypto graphic hash function Hashing means taking in input streng of any lengeth 3.immutability
Picture spreedsheat that is dupilicated thousand of time across network of computer then imagine this network is designed regularly update thiseand you have the basic understanding of blockchain . Informetion on blockchain are as shared and recounciled How blockchain work
The main uses peer to peer network is file sharing In peer to peer system ther is no centeral authority Why people use peer to peer network

Decenteralized file storage on the internet brings clear benefit. Distrbuting data through out the nnetwork protect file frome getting hacked or lost. Interplanetery file system make it easy to conceptualized how distributed web may operet. E.File storage
Blockchain technology is an advanced database mechanism that allow transparent informetion sharing within business network The blockchain datbase stores data in block that are linked together in chain In generally
