Now I can proudly give a lecture on block chain technology. Thank u Reddy gaaru. Superb ga explanation icchaaru

[@romanmakarov2021]

Navin, your explanations are awesome because you always compare new information to something that people already know. Thank you very much for your work, time and energy! Thanks to you, I understood a lot

[@sardarzain2551]

These are also my words perfectly

[@hashilsemin2414]

You really did struggles to present videos back 3 years...now it's to easy , You really are a hard-working man !!

[@kostarev2000]

Meeku chaala kruthagnyathalu Naveen Reddy gaaru. Meeru baaga chaduvu cheptunnaru maaku. Chala suluvuga undi Blockchain vishyala gurinchi ardham chesukodaniki.

[@manassav]

please show it with a simple program how it works...

[@MrRaj112]

Great Sir😁😆🤩❤️ understood nice. That's why Bitcoin wallet gives different $ receiving address,. We can change it one click, but money never goes to other's wallet!!🤩😆🤩🔥 because the latest address nodes is connected to all previous nodes 🤩😆🤩🔥🔥❤️❤️ sooo 100% safe transection happen 😆😆🤩🤩🔥❤️

[@pankajkcodes]

Today I learn Blockchain Very confidently Before that I was very confused

Please sir make more videos on block chain , how to implement blockchain, some more real life examples, what are the hardware or software used in blockchain ( what are the technologies). And how it works in banking ?

[@sjljc2019]

As you mentioned that change in data can be found by the difference in Keys but in order to check that we need to scan the key of previous and current block. Assume that there are crores of blocks, so will it possible to check the data integrity in the 11000th block via this Scan and Validate method. Awaiting reply...

[@manujsrivastava106]

Ofcourse i need everthing about blockchain..brilliant explaination..

I liked the content. Thx 🤞

[@balanced-living]

I liked your way of explaining. Very practical. Keep making videos.Great job Naveen :)

[@samiyasiddiqui1059]

can I post ur Blockchain tutorial videos on my website?

[@valvlog4665]

Excellent video. Thanks for making. I was engaged the whole way thru. 100% view time. I especially liked your "hype killing" side comments. "Block chain is like a linked list where the link is thru the hash value of each block" Yup, link lists circa 1970, block aka records circa 1965. The hype is just the same as when RDB and OO and web browsers first hit the IT landscape. I agree with other - please make more block chain vids --- if you have the time. Q's that popped into my head while watching were: 1) What software actually hosts the block chain management? Are there the equivalent of RDBs, like Oracle or DB2, for block chains? (What about freebies like PostgreSQL equivalent.) 2) Who is hosting these block chain management servers? It costs money to do that. So is it the likes of Google? I assume you pay to have someone to use their block chain services. 3) What happens when you get a hash key collision? (This of course can occur outside of block chain.) 4) All very well one saying you know if there's tampering, as the key is rehashed and the chain is broken...so what? What I want is prevention. Like a virus scanner stops corruption ahead of time. As you say, block chain is NOT exclusively for bitcoin, though you'd think it was given the "same sentence syndrome" where they are always mentioned together.

[@praval_sharma]

nice explanation .....want to see more videos on blockchain
