[ANN] 42-coin Development Discussion Thread

That is, encrypt for your own use, Laser? (Like perhaps wallet passwords)

Or can another user decrypt a message? (So, person-to-person comms?)

Only the owner of pubkey can decrypt the message. So, for person-to-person comms you need to exchange the pubkeys with each other.

My pubkey is here: https://github.com/42-coin/42/blob/master/src/alert.cpp#L19

Edit.
Compressed:

So, this is you, L.?

And ah! 'Only the owner of pubkey can decrypt the message. So, for person-to-person comms you need to exchange the pubkeys with each other.'

EDIT: okay, 'Only the owner of the pubkey can decrypt the message.'

Hmmm . . . so my pubkey is: 022fbfc749b4fe79774c1b47e40ddec5f32cc96c51b5a4db1b7990f7a3809bf6e0 __??

Okay:

One: I generate a new address.

Two: I validate that new address -- and there is my pubkey!

Three: I use that pubkey to encrypt a message, and I get 'X' -- the encrypted message.

So far, I understand.

But what confuses me is:

to get a successful decrypt, I use: decryptmessage[space]ADDRESS (not privkey)[space]encrypted message

??

This seems as though the 'pubkey' is really the address?

So, this is you, L.?

This part:

04c97d0030cd9054e9823ed911c26b94c1633f03bf3c46f277cb5cc49d717e71d46fa33d8202c95 e900f1861532a01384504432edeeb5296f9558f06c08bebab41

So, first, you create a pubkey (for you). And then you then send it to three people. So four people hold that pubkey.

People need your pubkey to encrypt a message for you.

Right, and it corresponds to the address 4NvVd3gL3RJaXZejtuJptx9Jd9zUonEjZZ (it is not necessary to create a new address each time).

So, Laser has my pubkey: 022fbfc749b4fe79774c1b47e40ddec5f32cc96c51b5a4db1b7990f7a3809bf6e0

And I encrypt a message to my pubkey. And I send that encrypted message to Laser.

Then Laser should be able to decrypt it with my pubkey.

Your address is = your pubkey (public key) + your privkey (private key).

So, only the owner of the address can decrypt it.

Tomorrow. Start all over again. Excellent progress today. Thank you for your patience

Ane the terms, and the English: got to get those finely tuned, to avoid confusion.

Having a Plan: 2019-2020

EDITED:

https://coinmarketcap.com/currencies/42-coin/#markets -- Number 837. Let's work on that.

Our community should have A Plan. So, we discuss things either 'front of house' or in PMs, and across the threads. Then some one updates this post.

Encryption We are practising, on the ANN thread, with the 'encryption engine' in our wallet. It works -- I just need to learn how to use it properly.

Paper-Wallet Generators No apologies here. There was some confusion about one of the generators. But Laser assures us that they are both (they are listed on Page One here) safe and functional. We'll continue to trial them both (with help from 'WB' over on Tgram). And will post a further report here.

Markets I have finally decided to trade on altmarkets.io. It has a good review. And how do we get it listed on Coinmarketcap?

Anonymous transactions We practised with 'long addresses' last year. And in 2020, we need to develop this important 42-coin asset.

'Crypto Kindergarten' I am running a small project with a crypto kindergarten elsewhere (not 42-coin).


IMHO: 42-coin should be the simplest, least technical crypto instrument on the Planet. Full stop. Our 'bigness' should be community, particularly helping newcomers.
