    Couldn't attend the BCH city conference? 🐨 No worries, here are Gabriel Cardona's slides from his two presentations. The first one is more developer focused and second one is similar but more consumer focused.

    Privacy is a basic human right. What you do in your own home with your own body and your own mind is your own prerogative.

    People have been doing what they want with their own minds and bodies for as long as there has been minds and bodies and prohibition is never going to stop that.

    bitcoin is a system where nobody can force anyone to do anything; if you want something, you either do it yourself or persuade others to do it with you. That's it.

    The Bitcoin Unlimited Top Three Near-Term Tasks:

    Posted: 04 Sep 2019 02:20 PM PDT

    I've been working on a prototype Jonathan Silverblood's proposed CashIntents. CashIntents will allow for verifiable, trustless, and decentralized payment information. For example: "pokkst#12435 sent you $10 USD on September 4th, 2019"

    Posted: 04 Sep 2019 01:45 PM PDT

    An example transaction can be found here: https://explorer.bitcoin.com/tbch/tx/dd5e19e8a63279cb87e000abf31211b723c2c2b5a0a8ea475a3beeb6a0a7d646

    This system utilizes the OP_RETURN of a transaction, with various portions of the OP_RETURN containing data that will allow the recipient to verify that the sender is who they say they are, and that they did in fact send you that money.

    When sending, the sender will include the transaction id of the recipient's Cash Account (the txid that registered the Cash Account), and the transaction id for their own Cash Account (the txid that registered their own Cash Account). The sender will also include the amount sent, and the currency in which they used, as well as a timestamp.

    Then the program will take the recipient txid, sender txid, amount, currency, and timestamp and combine the strings together like so:

    recipienttxidsendertxidamountcurrencytimestamp

    then that string is hashed:

    3adb37317e844d995aa6225905bfb0a062b98b10f8579b6f80945088b410bab3

    then this hash is signed with the sender Cash Account's address, which will produce a signature like so:

    HxBnqQdGRsin9+1FkFAD/8oWb87YAOhexiK4AJaNpEdydk0BZzWfrxR+WuclKNk3owynWUZXTFGFj4+gqpcAHKw=

    this is then attached to the OP_RETURN at the very end, and the sender sends the transaction.

    On the receiver's end, they will receive the transaction and detect that there is an OP_RETURN. It will parse the OP_RETURN to see if it's a CashIntent OP_RETURN. If it is, it will grab the data from the OP_RETURN like so:

    recipient txid, sender txid, amount, currency, timestamp, signature

    using the sender txid, we can grab the address that the sender signed with (as it is supposed to be signed with the Cash Account address of the sender) using Cash Account lookup servers and block explorers to grab the necessary data to parse the address:

    bitcoincash:q(...)

    we can then take each variable like the sender did, and combine them into one string

    recipienttxidsendertxidamountcurrencytimestamp

    then hash that string to get the same hash that the sender used in his message (we do this locally that way the sender doesn't have to store it on the chain, and so we can verify ourselves):

    3adb37317e844d995aa6225905bfb0a062b98b10f8579b6f80945088b410bab3

    then we take the signature, hash, and address and verify that the signature is in fact valid. If it verifies, then we can be certain that the sender is in fact who they say they are and that they did send us this money.

    This can then be displayed in-app when viewing the transaction as:

    pokkst#12435 sent you $10 USD on September 4th, 2019

    This is still a prototype, and will need to be finished before rolling it out in Crescent Cash as the first wallet to support CashIntents, but it is working and will hopefully be ready soon. :)

    **Today’s my birthday, I have a present to share!***

    Posted: 04 Sep 2019 11:29 PM PDT

    BCH community,

    I've learned and grown a lot with this sub. Our interactions helped develop my understanding of blockchain technology, my study of crypto markets and a sincere appreciation for a project that benefits everyone. 9/5 marks another year of life and I'd like to celebrate my special day with the fine individuals on this subreddit. While the act of opening gifts is enjoyable, I believe that the best presents are those we can share with others. As such, here is my gift to all of you;

    These are customized, Local.bitcoin.com stickers to share our medium with the masses. I'll be posting them in high places for everyone to see!

    Regards,

    -Swole

    PS; I wouldn't complain if anyone felt like donating a few sats for a slice of cake :)

    ...we have sound fiscal management giving us the ability to fund our own development.

    ...we found the most critical bug in Core and ABC since the early days.

    ...we have consistently had fewer bugs than ABC since the fork.

    ...we began the innovation in block compression techniques, and currently have the best one (Graphene) deployed in mainnet.

    ...we created the strongest tokenization system on Bitcoin-family crypto.

    ...we proposed OP_DSV, which became OP_CDS.

    ...we initiated the full node scaling performance effort, and currently have the highest performing full node on BCH.

    ...we don't destroy value and waste time by disparaging our allies on social media.
