  they just embed info in tx_extra

  no scripting, but there in an arbitrary binary data store

  <s​pirobel:monero.social> it would be possible to also do scripting. The colored coins concept can also incorporate smart contracts. People like to think that this can be prevented, but it can't.
• 01:47
  m-relay
  <c​omradeblin:matrix.org> There is a reason why monero does not have implemented smartcontracts

  @m-relay Seems the biggest issue is the smart contracts can't be private. Doesn't really matter if you use buffer wallets in between, no?
• 03:43

  and what about that tari thing? seems to be some sort of scripting language for monero

  Hi.
• 20:04
  Kapun
  I have following error during compile monero on Mac m1 computer: paste.debian.net/1296831
• 20:04
  Kapun
  Can anyone help?
• 20:09

  Are you trying to compile github.com/moneroexamples/mymonero-simplewallet ?
• 20:09
  sech1
  Because there's no "libblockchain_db" in Monero build
• 20:10
  Kapun
  I am trying to compile monero: github.com/monero-project/monero
• 20:14
  sech1
  Definitely not
• 20:14
  sech1
  You're compiling something else
• 20:14
  sech1
  cryptonote::get_reserve_reward is not used anywhere in current Monero code
• 20:15
  sech1
  Either that, or you're compiling Monero code from 2016
• 20:19
  sech1
  Ahhh, found it. You're compiling Zephyr. This is Monero dev channel, you should ask in Zephyr discord.
• 20:21
  Kapun
  I apologize; I got very little sleep today. Here is the Zephyr repository: github.com/ZephyrProtocol/zephyr.
• 20:23
  Kapun
  I'm surprised; they are using such an outdated version of Monero's source code.

  <e​mlily:matrix.org> i made a thing! *probably* not very interesting to people since it's pretty basic and also my first time using rust lol but. github.com/easrng/xmr_ts
• 20:38
  m-relay
  <e​mlily:matrix.org> it puts arbitrary hashes on chain
• 20:38

  <e​mlily:matrix.org> matrix.monero.social/_matrix/media/…matrix.org/KJCpvfUdewZwJpOzRQYtxuMZ
• 20:40
  m-relay
  <e​mlily:matrix.org> doesn't use tx_extra so they should be indistingushable from normal transactions
• 20:45
  sech1
  plowsof wrong Zephyr :D
• 20:47
  sech1
  e​mlily it puts hashes where? Instead of stealth addresses, so you effectively burn XMR every time?
• 20:48
  m-relay
  <p​lowsof:matrix.org> sech1 oops lol
• 20:50
  m-relay
  <e​mlily:matrix.org> it derives a view key from the hash, and yeah it burns an atomic unit but that's negligible compared to the fee anyway
• 20:53
  m-relay
  <e​mlily:matrix.org> the flow for hashing is hash data -> derive keypair -> generate address with the view key as the public key from the keypair and an empty spend key
• 20:53
  m-relay
  <e​mlily:matrix.org> then you send a transaction to the address
• 20:53
  sech1
  Hmm, and the spend key is all 0. You could derive it too, so it would be possible to have full access to this wallet address
• 20:54
  m-relay
  <e​mlily:matrix.org> no reason to, really. you aren't supposed to send usable amounts of xmr to it
• 20:54
  sech1
  The easy way to put arbitrary 32 bytes on the blockchain is to put them where stealth address would be. It also burns coins, but it's easier to implement
• 20:55
  m-relay
  <e​mlily:matrix.org> but is that usable with unmodified wallets?
• 20:55
  sech1
  It will require a modified wallet though
• 20:55
  m-relay
  <e​mlily:matrix.org> lol
• 20:55
  sech1
  Sorry, my category of "easy" is different from non-dev people :D
• 20:56
  m-relay
  <e​dge7:matrix.org> What's the point in burning coins? Am struggling to understand
• 20:57
  m-relay
  <e​mlily:matrix.org> because an atomic unit is basically free and it's the easiest way to make a transaction
• 20:59
  m-relay
  <e​dge7:matrix.org> But what is the purpose of such a transaction
• 20:59
  m-relay
  <e​dge7:matrix.org> ?
• 21:01
  rbrunner
  If you can put a hash into the blockchain you can e.g. prove that a certain document existed already at a given point in time
• 21:01
  moneromoooo
  I believe the burning is merely a necessary side effect, not a goal.
• 21:01
  m-relay
  <e​mlily:matrix.org> yeah exactly!
• 21:02
  m-relay
  <e​dge7:matrix.org> Ah like ordinals sort of
• 21:02
  rbrunner
  I wonder whether that would really be without any side effects if people started to burn coins now left and right ...
• 21:02
  rbrunner
  Even if only in atomic units
• 21:03
  sech1
  If they use unmodified wallets for this, it shouldn't be a privacy problem
• 21:03
  sech1
  Transactions will look the same
• 21:04
  m-relay
  <e​dge7:matrix.org> Basically just to save something. But it's not possible to pass the ownership with the above approach. Correct?
• 21:05
  rbrunner
  Yeah, but more and more enotes would become "dead ends". Maybe you really can't see any effect of that, nobody could see they don't become true spends anymore, ever
• 21:05
  m-relay
  <e​mlily:matrix.org> right, it just timestamps data
• 21:06
  m-relay
  <e​mlily:matrix.org> you could use something like this to provide consensus for a sidechain tho
• 21:06
  rbrunner
  "If your only tool is a hammer, everything looks like a nail" comes to mind. Plenty of blockchains around that *want* you to do such stuff
• 21:06
  m-relay
  <b​oog900:monero.social> No one without the hash would be able to prove that these enotes are dead ends so it depends what this is being used for.
• 21:06
  rbrunner
  Why bother Monero?
• 21:07
  sech1
  Statistically, they would be used N-1 times (no true spend), compared to outputs which are eventually spent
• 21:07
  sech1
  *used as decoys in rings
• 21:07
  rbrunner
  Maybe we could start kind of a contest: "Most creative (ab)use of Monero and its blockchain" ...
• 21:07
  sech1
  I mean seen in rings
• 21:08
  sech1
  But statistics operates with huge number of transactions, so you still can't tell anything about an individual transaction
• 21:08
  rbrunner
  Does anybody remember the crazy person that wanted to encode messages by using the last digits of amounts?
• 21:08
  m-relay
  <e​mlily:matrix.org> oh no lol
• 21:15
  moneromoooo
  Yeah, he left after going bankrupt after a PoC where they mistakenly used the first digits of amounts.
