海外TECH	DEV Community	What is the difference between a blockchain and a traditional database?	https://dev.to/andreapicoli2/what-is-the-difference-between-a-blockchain-and-a-traditional-database-5a14	What is the difference between a blockchain and a traditional database Blockchain technology which joined the ranks of high speed digital technologies in with the advent of bitcoin soon made its way into the Internet and communications as a tool for storing and managing data But what is the difference between storing data in a blockchain network and storing data in a traditional database In an article published on the Medium website Shaan Ray a consultant and expert on blockchain explores the fundamental differences between a blockchain and a traditional database and explains how each of these databases is designed and works Traditional databaseTraditional databases use a client server network architecture In this architecture the user known as the client can modify and modify the data stored on a centralized server computer if licensed In the meantime database control remains in the hands of a designated authority that also verifies the customer s identity and credibility before accessing the database This designated authority is responsible for managing the database Therefore if the security of the reference is compromised there is a possibility of changing or even deleting the data What is the difference between a blockchain and a traditional database Traditional databaseTo better understand this concept we can use the Wikipedia website as an example In Wikipedia which is a comprehensive encyclopedia anyone with an account can add new articles or edit an article for improvement However the ultimate control of Wikipedia data is in the hands of one centralized entity blockchain databasesblockchain databases consist of several nodes or computers Network nodes are computers that participate in the management of a blockchain database all nodes check new data and can enter this data into a blockchain based database For new data to be added to the blockchain the majority of nodes must be unanimous This consensus mechanism ensures network security and makes data manipulation difficult In the Bitcoin blockchain consensus and consensus are obtained using the Proof of Work method This method involves solving complex hashing puzzles in which the data is encrypted and virtually impossible to change or delete Other blockchains such as Ethereum also use the Proof of stake method as their consensus mechanism What is the difference between a blockchain and a traditional database blockchain databaseIntegrity and transparencyThe main thing that distinguishes Blockchain technology from traditional database technology is the general validation of data which is made possible through the integrity and transparency of the network Integrity means that each user can be sure that the data they are retrieving has remained intact and unchanged since its inception Block transparency also allows all users to monitor how blocks are joining the blockchain over time CRUD vs reading and writingIn a traditional database the client can perform four different functions on the data create read update and delete These four basic functions are called CRUDs A word that consists of the initials of the four English words Create Read Update and Delete However the blockchain structure is designed to allow only the user to add data In fact the blockchain user can only add more data in the form of blocks to the blockchain All previous data is permanently stored and cannot be changed Therefore the only operations that can be performed on blockchain data are read and write The read operation means requesting and retrieving data from the blockchain and the write operation means adding more data to the blockchain Validation and writingBlockchain allows you to perform two basic operations related to transactions validating a transaction and writing a new transaction A transaction is an operation that changes the state of the data in a blockchain to a new state In other words transactions do not delete or change previous data Rather they change their situation For example a new transaction can change the status of an inbound transaction in the past from unspent to spent To better understand this imagine a practical transaction For example if it is recorded in the blockchain that Ali Bitcoin wallet contains million bitcoins this figure will be stored in the blockchain forever When Ali spends bitcoins the transaction is recorded on the blockchain and brings his balance to bitcoins However because the data is only added to the blockchain and the old data is not changed the causal balance which was previously million bitcoins remains permanently in the blockchain and anyone who wants to click on the data The old monitor will have access to these records For this reason the blockchain is an immutable and distributed general ledger Decentralized control the main difference between a blockchain and a traditional databaseDecentralized control eliminates the risks and harms of centralized control Anyone who has sufficient access to a centralized database can corrupt or completely destroy the data in it Therefore centralized database users must have complete confidence in the security infrastructure of database management and governance Blockchain technology has institutionalized security in its structure by using decentralized data storage to solve this problem However blockchain technology is suitable for recording certain types of data and traditional databases for other types of data Before choosing a database any organization should be fully aware of their needs and expectations and evaluate their desired goal according to the strengths and weaknesses of each type of database	2021-09-21 04:18:49

海外TECH	Engadget	Netflix debuts free tier for Android users in Kenya	https://www.engadget.com/netflix-free-tier-android-kenya-043616484.html?src=rss	Netflix debuts free tier for Android users in KenyaNetflix has started offering potential paying subscribers in Kenya access to some of its content at no cost The streaming service has launched a free tier in the country that offers around one fourth the content available to paying subscribers It has no ads and won t even ask for payment information upon sign up ーa new subscriber will only need to confirm they re over and to type in their email address and password nbsp That said it does have limitations in addition to having a smaller selection It s only accessible on an Android device and users won t be able to download episodes for offline viewing or to cast shows on movies to a TV In the announcement post Netflix s Director of Product Innovation Cathy Conk said quot If you ve never watched Netflix before ーand many people in Kenya haven t ーthis is a great way to experience our service quot The company is hoping that the free tier would entice people to pay for the service This isn t the first time Netflix made some of its content free to access Last year it launched a quot watch free quot page where people can stream original movies such as Bird Box and the first episodes of popular shows like Stranger Things without even having to log in The free plan is new though and a spokesperson told Variety that it s launching first in Kenya as a way for the company to gather information on how effective it is in generating paying customers Netflix has been investing more heavily in new markets to offset its slowing growth in the US and other saturated markets and amidst an increasing number of rival streaming services Based on what the rep said we may see the free tier make its way to more regions in the future nbsp	2021-09-21 04:36:16
