I Made A Simple Presentation Video About Blockchain Technology!
"Blockchain as an opportunity!"

Most of the things in your video are not coherent with what a block chain is. Too much hype in your video, sorry. POW is the key in the blockchain/bitcoin world. No POW no real value. Databases work fine in those fields.
to both aditya and karartma
you ar both wrong.
the blockchain itself is not as glamourous as you set out.
imagine it this way
in the 1980's data was just stored on ledgers. technically these were called DataBase Management Systems (DBMS)
in the 90's they realised that they could link one piece of data in a table to another via 'relationships. thus began relational DataBase Management Systems (RDBMS)
now we have a new layer on top of RDBMS where datasets(groups, clusters, tables, ledgers, blocks of data) are linked to previous data... blockchain.
other things like HOW its linked. can differ. it does not need sha hashs, it can be anything. any type of cryptography or 'key' data..
the strength of it is not part of 'blockchain'. as that requires more layers of programming to achieve this.
neither is the decision to be on one system or multiple systems.. as that requires more layers of programming to achieve this.
so blockchain. is just layer 3 of DBMS, where as bitcoin has added more layers ontop. such as sha hashing the block of data(4). then PoW hashing the sha chain link(5) then distributing the data(6) and so on..
bitcoin has atleast 10 layers of security/tech.
where has blockchain is just a lil bit more expanded than RDBMS sitting at 3 layers.
yes blockchain allows more programmability to add more layers. but do not presume that extra layers are part of blockchain as default.
EG PoW, PoS, PoA is not default
decentralised or centralised is not default
yes the extra layers ontop have many possibilities and we have yet to explore them. but dont hype up the term 'blockchain' as if it is as secure as bitcoin
