Getting started

A first moeba

You cannot breed without a moeba in your account. There are three ways to get one, and the population page shows which are open to you right now.

A newborn is not ready at once. It becomes mature one minute after its randomness was fixed, on the ledger’s clock, and every moeba is born with five births in it, spent one per child whichever parent it is. Both facts are on every moeba’s page, with a plain yes or no on whether it can breed right now. The short wait is a rehearsal setting: the release profile matures a newborn in four hours.

Asking for a birth

One payment to the issuer account, then nothing. A minute or a few later the child is in your account, with its genome, parents and randomness sealed on it.

1. Pick two parents

   Both mature, both with births left, and not close kin: parent and child, or two full siblings, are refused. Either both are yours, or one is yours and the other is open to others on the ledger, at a price its keeper named.

2. Send one payment

   To the issuer, naming the two parents and carrying the fee, any price, and the birth’s own budget. That is the whole request. The moeba’s page builds it for you, amount and all, with your address filled in; if you sign with a wallet of your own, it shows you every field first.

   What the transaction looks like

   {
     "TransactionType": "Payment",
     "Account": "<your address>",
     "Destination": "rMmx5nHzoVJAoMTFWkgCCMrZryTaD682tr",
     "Amount": "23500000",
     "NetworkID": 21338,
     "HookParameters": [
       { "HookParameter": { "HookParameterName": "46", "HookParameterValue": "02" } },
       { "HookParameter": { "HookParameterName": "50", "HookParameterValue": "<parent 1 token id>" } },
       { "HookParameter": { "HookParameterName": "51", "HookParameterValue": "<parent 2 token id>" } }
     ]
   }

   The three hook parameters are what tell the issuer what you mean: F is the kind of request (02, a birth), P and Q are the two parents’ token ids. The names are the letters in hex; the amount is in drops (a million to the XAH) and is whatever the calculator above says, here written for a request that carried 23.5 XAH. Every request the site prepares is listed in the hooks chapter.

3. Read what the issuer said

   If a rule is broken the payment is refused on the spot and the reason is written into the transaction result: “parent is not mature”, “siblings cannot breed”, “underpaid”. Nothing but your own network fee is spent. If it is admitted, the birth holds one of the issuer’s four queue places and names the future ledger that will decide the child.

4. Wait a minute or a few

   The hooks wake themselves up ten or so times: capture the randomness, combine the genomes, mint, seal the records, charge each parent one birth, deliver the child to you, pay the other keeper. Nobody signs anything. The hooks chapter lets you drive these stages by hand.

5. Meet the child

   It appears under My moebas and on the population pages with its parents linked, its genome readable, and which copy of each locus came from which parent. It can breed one minute after its randomness was fixed.
