tx pubkey can be retrieved from tx_extra:

  bool add_tx_pub_key_to_extra(std::vector<uint8_t>& tx_extra, const crypto::public_key& tx_pub_key)
  {
    tx_extra.resize(tx_extra.size() + 1 + sizeof(crypto::public_key));
    tx_extra[tx_extra.size() - 1 - sizeof(crypto::public_key)] = TX_EXTRA_TAG_PUBKEY;
    *reinterpret_cast<crypto::public_key*>(&tx_extra[tx_extra.size() - sizeof(crypto::public_key)]) = tx_pub_key;
    return true;
  }

(see https://github.com/monero-project/monero/blob/7499837a6fe8d3533e1360dce8f3ba230ff76042/src/cryptonote_basic/cryptonote_format_utils.cpp#L651-L656)

or, simply looking at the tx info from the onion explorer

from go-monero.

now, once we implement get_block_header_by_height, we'll be able to lookup the age of all those blocks in a single call and figure out the timescale

hmm sounds like the ring members are not really matching what shows up on xmrchain .. looking at that block distribution above, we can tell that's not really what the gamma distribution would end up looking like

welp, turns out the key offsets uses differential encoding, so we gotta translate that array before submitting to /get_outs:

that looks much more like what we'd expect

from go-monero.

cirocosta commented on July 17, 2024

tbh, calling this done and leaving timescale for another time - the AGE column is definitely good enough to give you an idea of the distribution when you have just a few inputs

IIRC the number of inputs can be large

outputs: min=2, max=16
inputs: min=1, max=capped-by-size (CRYPTONOTE_MAX_TX_SIZE, 149.4kB)
