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

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

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).

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'.

Great job on the article!

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.

After downloading it I extracted it to a new folder. After trying to sync and then closing the 0.9 daemon, the new folder disappeared and a lmdb folder appeared in my bitmonero folder.

bummer. for the record, the link in my sig is not *my* win64 beta binaries, they were the ones released for testing.
when you say "stuck".. what happened? Did you try restarting it? sorry for the OT.

Moved from spec thread..........

Again I decided to download the entire BC instead of trying to figure out the converter and it was zipping along and the a mere 270 blocks from the end it kept repeatedly saying it was 270 blocks behind. Again I was not at my comp for a while and I estimate that was going on for ~1 hr. When I typed exit it said a stop signal was sent and I'm unsure if anything else was noted on the daemon. after 20 min I just Xed it. I did not try restarting because the official 0.9 will be released not soon but imminently Grin

I think that it will resume from where it was stuck once you start it again. You see, since it is using the database the info is saved to disk as it is being downloaded. So even the dreaded "Saving blockchain to disk" is gone in this version...

This is what I got.......2015-Oct-03 07:57:54.896332 [node] Stop signal sent
2015-Oct-03 08:06:50.960716 Got control signal 2. Exiting without saving...

I had set up the Beta in a new folder and I just checked now and that folder is gone.

In my bitmonero folder the first thing listed is lmdb and the info above is from the text document in bitmonero.

In my bitmonero folder is monero.win.x64.latest which is 0.8.8.4 which has it's own text document. My wallets etc are there.

The only thing I see from 0.9 is the lmdb folder and I see no way of starting 0.9

I will now go back to patiently waiting for the official 0.9

Yours truly, The Drooling Masses©

I don't understand. The link in my signature is a zip file. Unzip the file into a new folder... on your desktop, anywhere. Then doubleclick on the new bitmonerod.exe
