Save any files to namecoin blockchain

[gmaxwell]

Most of the insertion slowness is probably the recursive IsFromMe / IsConfirmed checks in coin selection for unspent change in coin selection, as IsConfrimed recursively does that along the whole input tree with no-memoization. Commenting out lines 607 to 616 in wallet.cpp and I expect spending unconfirmed coins will become much faster.

What an awesome use case! What is the theoretical maximum growth of the NMC blockchain?

I still haven't sorted out what to do when some of the file parts expires.

It is possible to look at even expired domains, but I am not sure how.

One more argument towards storing the actual data in a faster place. Have you ever heard of bittorrent magnet links? The file itself could be encrypted so it would be some kind of do it yourself mega.

You need seeders for magnets, though.

Use name_history instead of name_show, then fetch the last (i.e. latest) record of the result. If the domain has expired, the number of blocks found since the expiration time simply shows up as a negative number, e.g.

Code:

namecoin name_history d/capitalism

gives you

...
"expires_in : -144"
...

In other words: d/capitalism has expired yesterday.

you can see here how you are spamming the chain: http://nx.bit  (http://blockchained.com/namecoin)

When I look at it, some people dumped 2 nonsensical junk files, me and some other guy wrote something in plaintext and that's about it. So nothing important happened there.

Namecoin has nothing on bitcoin testnet:

Code:

(bitcoind -testnet getrawtransaction 73e64e38faea386c88a578fd1919bcdba3d0b3af7b6302bf6ee1b423dc4e4333 ; bitcoind -testnet getrawtransaction d85af546147ff78dfb06e9469ddfc84adc3ce00cda54db8d65b7617ff2b7661a) | xxd -r -p | play -tul -
