Day of Days of Code amp Scrum Finished Courses Looking For New OnesHappy new week everyone I finally finished Next js amp React by Maximilian Schwarzmüller and SQLZoo s SQL Tutorial Both of them were great resources for learning Next js and SQL respectively Now I can finally move on to other resources I m most likely going to prioritize learning how to use MySQL next Not sure which resource to use yet but it s what I ll be focusing on Anyway let s move on to my daily report YesterdayI learned how to use the next auth package for easier handling of authentication in Next js practiced using different JOINs for merging SQL tables and continued reading the Nexus Guide Today Next jslearned more about managing user session using next auth and how to programmatically redirect to a different URL using useRouter and router rewrite in Next js finished Next js amp React by Maximilian Schwarzmüller SQLlearned how to use multiple self JOINs finished SQLZoo s SQL Tutorial Scrumfinished reading the Nexus guide for scaling Scrum Thank you for reading Have a good day Resources Recommended ReadingsNext js amp React by Maximilian SchwarzmüllerNext js official documentationSQLZoo s SQL TutorialThe Scrum GuideNexus guide DISCLAIMERThis is not a guide it is just me sharing my experiences and learnings This post only expresses my thoughts and opinions based on my limited knowledge and is in no way a substitute for actual references If I ever make a mistake or if you disagree I would appreciate corrections in the comments Other MediaFeel free to reach out to me in other media |

What is blockchain? |
https://dev.to/cngroup_cz/what-is-blockchain-1lgp
|
What is blockchain You will find on Google many definitions of blockchain so many that I will only try to summarise some of them Blockchain is a system of recording information in a way that makes it difficult or impossible to change hack or cheat a system A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across an entire network of computer systems on the blockchain Source euromoney com Note this is a widely accepted definition but “impossible is not actually the exact word to use Maybe we can agree the statement is true in production implementations where there are many contexts and also a lot of physical limitations However it is not necessarily mathematically impossible to cheat there s a good description here by J H White in chapter You can think of the blockchain as a specific type of database It is storing data using blocks that are chained together New data is entered into new blocks and once the block is filled with data this is chained onto a previous block and this makes the data chained together in chronological order Simplified is a list of data blocks that are linked together with a timestamp As common databases have already known data types the most common use for blockchain so far has been as a ledger for transactions Decentralised blockchains are immutable which means that the data entered is irreversible For Bitcoin this means that transactions are permanently recorded and viewable by anyone The main difference between a blockchain and a databaseActually it depends on what you mean by “a database Of course we can refer to any organised group of files linked by some logic and maybe an API as a database right We can even consider an Excel document with formulas and links between sheets as a database as well Technically speaking both of these are correct Actually in literature there are many opinions regarding classification models so I can recommend this article to you it should help you get a better idea about this However in this comparison we will focus more on the differences between a common SQL NoSQL DBMS and a blockchain A key difference is in the way data are structured A blockchain collects and groups data in blocks that have a certain capacity in terms of storage When a block is filled then it is linked to the previous block using a hash of the entire previous block content Another key difference is that the blockchain is distributed it does not store data in a single place and does not have a single point of failure Of course there are also other distributed DBMS such as Cassandra for example which stores data using multiple nodes and provides a lot of support for data consistency But there is one more key difference an important one that makes blockchain technology so famous and revolutionary ーit makes data immutable There is no DML that allows you to modify the data no matter what permission levels you have You cannot cheat you cannot root And what is more fascinating is that the solution was there with us all the time and it is a mathematical one We do not need to struggle to make systems more secure to hide sensitive data to use more and more powerful servers to handle security and block attacks We actually only needed to do the reverse to share them with everyone and to create links between blocks of data so if anyone changed anything all the others would know It is security by transparency and hiding things where everyone can see them Some historyThe history of blockchain as a popular trend started with the publication of the whitepaper Bitcoin A Peer to Peer Electronic Cash System written by someone calling themselves Satoshi Nakamoto in The bitcoin project started the cryptocurrency era being the first implementation of a peer to peer network as a solution to the double spending problem Even though this project continues to function and circulate successfully to date Nakamoto s ideas behind the creation of bitcoin have exceeded the original use case Now these ideas are known collectively and independently as the blockchain However the underlying maths concepts are older than the bitcoin implementation the PP concept was already known and other implementations existed before blockchain but they did not become so popular and also did not have the same technical results in terms of benefits So were there predecessors of blockchain The answer is yes Here were some DigiCash ーfounded in by David Chaum an American cryptographer It was based on the mechanism named “Blind Signature an innovation that eventually led to the development of blockchain technology The whitepaper describing it was written even earlier in HashCash ーan email PoW system designed to figure out spam emails and DoS attacks It was developed in by Adam Back but the documentation was released years later B Money ーan early age distributed cash system proposed by Wei Dai in who also developed Crypto The smallest subunit of Ether is wei named after him E Gold Ltd ーdigital gold currency founded in by Douglas Jackson and Barry Downey They were using precious metals as the underlying currency as these are globally acceptable Bitgold ーalthough not implemented it was proposed by Nick Szabo in It is one of the best known decentralised virtual currency projects undertaken before blockchain Bitgold and bitcoin are so similar that at one point people thought Nick Szabo actually was the anonymous Satoshi Nakamoto |

Apple x s revised Dutch dating app payment changes are under reviewAn antitrust regulator in the Netherlands is once again investigating whether Apple has done enough to comply with its order over dating app alternative payment options after Apple said it would still require developers to pay a commission for using a third party payment system On February it was revealed that Apple intended to charge developers a commission fee for dutch dating apps in the App Store that use alternate payment methods than the existing in app purchases mechanism The Authority for Consumers and Markets ACM is now looking into whether Apple complies with the order under the new measure The ACM requires Apple to allow dating apps in the Netherlands to handle in app purchases through other methods which Apple has worked to comply with However Apple said it intended to collect its commission from off platform app related purchases with the rate down from to exclude the costs of payment processing Read more |
