ACHIEVEMENT 2: BLOCKCHAIN SECURITY

#Definition of Block chain security
Blockchain security is a comprehensive risk management system for a blockchain network such as binance, luno and many others, using cybersecurity frameworks, with best precautions and practices against fraud and money laundering
Blockchain is a strong security network build to ensure trust in an untrusty era, making it very secure.
Block chain is a ledger, how?
Firstly, a ledger is a book in which a bank, business firm, etc. records its financial accounts. So this is to say in a block chain security system transactions being made are recorded and confidential to the system and the user, Blockchain, a Distributed Ledger Technology (DLT), is focused on creating trust in an untrusting ecosystem, making it a potentially strong cybersecurity technology.
It is a ledger system which is usually decentralized, but information is transparently available to members of the specific blockchain. All members (or nodes) can record, pass along and view any transactional data that are available or encrypted onto their blockchain.
##Advantages of block chain
Blockchain’s inherently decentralized nature makes it the perfect technology for cybersecurity.
It is also connected to personal details like BVN (bank verification number) in order to reduce the risk of scamming. The ledger technology has virtually endless uses in everything from medical and financial data sharing to anti-money laundering monitoring and encrypted messaging platforms.
This process creates trust while also maintaining a high level of data integrity. In essence, the distributed nature of blockchain provides no “hackable” entrance or point of failure that detrimentally exposes entire datasets.
First implemented as the operational network behind Bitcoin, blockchain is now used in more than 1,000 different cryptocurrencies, a number that grows almost daily.
DLT (Distributed Ledger system Technology) protects the integrity of cryptos through encryption methods and public information sharing.
The legitimacy of cryptocurrency purchases by individuals is ensured because they can trace the transfer of the currency to its origin. Encryption helps control the amount of cryptocurrencies being created, thus stabilizing value.

Some block chain networks also have their own coins such as BNB, BTC, STEEM, ETHERIUM, etc.
Going by my own understanding block chain security if the best cyber network security network for financial and other transactions because it is highly confidential and encrypted to avoid fraud and money laundry.
There are many block chain security networks such as Binance, Luno wallet, Trust wallet etc which are safe and reliable.
