Hello

any IOST tech guy available ?

i have one query

i want to retrieve particular block in my smart contract using blocknumber

blockinfo() gives current block ..

C

any method availble in smart contract

I

Don’t think it’s possible currently.

Yeah its not available

M

Blockinfo is the only chain function

purrrrrrrrrrrr

C

omg

hi all I have a question. Does IOST APi provide to hide some data on the blockchain? If for example I want to store sensitive data on the IOST blockchain like medial records?

D

medical

I

There’s no way to hide data on blockchains currently. Got to wait for the next generation of blockchains.

D

ah okay. Maybe encrypting the data or private nodes for now.....

Look into storj

I

You could use file storage and keep the hashes on iOS T

I

hi what library framework is better vue or react?

C

id 637537420You could use file storage and keep the hashes on iOS T

yes i found solution .. i can store that in other contract using storage and call it from my contract function to search hashes .. its bad approach as i need to store redudent data that already available on blockchain ... but okay for the moments

I

id 999911120hi what library framework is better vue or react?

React.

I

thx

I

Vue is for React wanna bes.

M

React all the way.

BlockArcade is all React, even the games.

🤣

I

That’s how much I like it.

I only have worked with react. But if you now react, you will be also familiar with React Native to built native mobile apps :)

D

to build

Exactly!

I

There’s React Desktop now too.

D

cool!

I

I hope to see a focus on private data some time in the future.

what about expo (built on react) is it worth it or expo is too limited?

Expo is cool, totally worth it.

I

Expo is used with React Native too.

Hey guys, is it possible to securely and anonymously save data into iost blockchain?

I

ElviᚱusHey guys, is it possible to securely and anonymously save data into iost blockchain?

Like nobody knows the addy that saved or the info is anonymous?

E

id 929675231Like nobody knows the addy that saved or the info is anonymous?

I don't get it 😅

No method to store private data on chain unfortunate.

Everything in every transaction is public.

I

You could encrypt it, but that’s not enough since the encryption could be broken at a future date.

Haa, thats a bummer in a way

E

Do you know if the foundation has any plans to have such feature integrated?

Haven't heard of privacy being a big focus, but you can always run your own private IOST chain.

I

and have software that watches your private chain to record important public information on the main chain.
