Does anyone know a site that features more advanced charts for Monero?
It's easy enough to find block explorers and exchanges with the set of charts generally available for all currencies (hashrate and exchange rate etc)
What I am looking for is for example # of transactions per block, avg fee per tx/block, avg size per tx, etc
Related to this: does anyone know the current size of the "global output list"? Isn't that a major scalability concern? (as it's monotonically increasing)
Well, its encoded pretty poorly currently but aside from that it fundamentally shouldn't be very large compared to the outputs themselves, so not by itself a scalability concern (other than the implementation needing work someday).
Isn't it a 64-bit # that's just monotonically increasing? I think that was his point(?), not sure.
I meant the lookup tables for it.
Ah, ok.
*whistling nonchalantly* "Nothing to see here, folks."

If it is, here's some fun math:
2^64 = ~18.45 quintillion
/ 1,000,000 tx / sec (pie in the sky)
/ 1,000 outputs / tx (pie in the sky)
/ 86,400 sec / day
/ 365 days / year
= ~585 years before we run out of space

Some question for the devs: What hash functions does Monero use for computing tx ids and key images?
The txids use keccak. The key images computed by hashing the tx public key using keccak to get a curve point*, then multiplying by the private key.
* Using some crypto that is beyond my comprehension. See ge_fromfe_frombytes_vartime in crypto-ops.c
Thanks! You are referring to plain Keccak and not CryptoNight, right?
Yes cn_fast_hash which calls keccak1600. CryptoNight is cn_slow_hash
Thanks. BTW, hash length seems to be 256 bits for both.
The wizards at Wikipedia have removed it now, but: https://en.wikipedia.org/w/index.php?title=SHA-3&oldid=676252215#Examples_of_SHA-3_and_Keccak_variants
cn_fast_hash produces the same output as Keccak-256. CN uses this everywhere it needs a hash function AFAIK (besides POW).

That's the kind of stuff I have in mind for evolving the stats page on moneroblocks.eu. In the meanwhile it has some info you might find useful.

MoneroMooo has been working on it in his own branch, but since it is not merged yet it probably isn't finished. See -> https://github.com/moneromooo-monero/bitmonero/commits/cold and in particular this commit: https://github.com/moneromooo-monero/bitmonero/commit/3c44e9fb6c1b57852d37780414ed6e42afc19afb
It worked, though I'm not sure it still applies, though any conflicts should not be hard to solve, if there are any.
What needs doing there is reducing the size of the exchange files, as they're a complete set of transactions plus relevant data, which means the whole deserilization code on the cold wallet is an attack surface. Cutting the size down will apparently make it easier to transfer via QR code scanning, avoiding attacks via filesystems and removable media firmware.
But it works

Has anyone thought more about this recently? With CryptoNote coins so focused on privacy and security it could be a nice addition

This change adds the ability to create a new unsigned transaction from a watch only wallet, and save it to a file. This file can then be moved to another computer/VM where a cold wallet may load it, sign it, and save it. That cold wallet does not need to have a blockchain nor daemon. The signed transaction file can then be moved back to the watch only wallet, which can load it and send it to the daemon.
Two new simplewallet commands to use it:
sign_transfer (on the cold wallet)
submit_transfer (on the watch only wallet)
The transfer command used on a watch only wallet now writes an unsigned transaction set in a file called 'unsigned_monero_tx' instead of submitting the tx to the daemon as a normal wallet does. The signed tx file is called 'signed_monero_tx'.
