If you check, as example, this transaction / raw:

Code:

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

This transaction shows 2 inputs but I can't find any pubkeys:

Code:

01000000 - version number
02 - number of inputs

f60b5e96f09422354ab150b0e506c4bffedaf20216d30059cc5a3061b4c83dff - tx hash (spending)

How can you determine what are the addresses of the inputs without a pubkey?

If you check your Watchlist, all the sorting options on the table header have "unreadreplies" instead of "watchlist" on the url, "redirecting" you out of the "watchlist" into the "Unread Replies / Updated Topics" section.

Manually inserting "watchlist" as the action parameter makes it work correctly, so I think this could easily be fixed.

Is there a way to choose which unspent outputs are included in a transaction?
Not sure, but it looks like it always includes all unspent outputs, even when not necessary. I guess it's trying to avoid address reuse?
Thanks

BitcoinCity.info

The idea was to graphically represent bitcoin transactions, and it ended up like this...
BitcoinCity uses Blockchain.info websocket API as source of data and Isomer as javascript graphics library.
It receives information on the latest bitcoin transactions, mostly still unconfirmed, and draws a little city based on the transaction info.
It tries to display as much information as possible about the transaction, with a touch of randomness to make each city as unique as possible.



City Elements
   
Ground
   - ground depth/elevation reflects transaction size in bytes

Building
   - each building shows either an input (north side of the street) or an output (south side of the street)
   - building colors have 2/3 parts based on the 7th and 8th byte of the input or output script, the 3rd part is forced to max, red channel for the inputs and green channel for the outputs
   
   - inputs and outputs with less than 1 btc form a round tent
   - 1 or more btc generates a building
   - the larger the value, the taller the building

   - inputs and outputs with multisig addresses are meant to look like castles, as they are more secure
   - if value >= 100 000 btc, you get a special building
   
Window
   - inputs and outputs need at least 1 btc to have windows
   - if value <= 10 btc, large windows will light up to represent the number of btc (ex: 2 lights up means the number of btc is >= 2, but < 3)
   - if value > 10 btc and < 100 000 btc, windows will light up to represent the input or output amount. Each column of windows represents the digit's place and each
     floor represents the digit. Bottom floor is 0, top floor is 9 (ex: transaction amount of 99 999 btc, all windows on top floor will be lit)
   
Roof
   - each roof is coloured green when unspent, red when spent, with variations according to the script type of the associated input or output
   - if a building should be taller than the limitations, it gets a roof twice the normal size
      
Flag
   - as blockchain.info displays tags on some of the addresses, these addresses will have a small white flag on their roof
   - transactions from some known services (Proofofexistence.com, Counterparty.io, Coinprism.info, OpenAssets, Blocksign.com, Coinspark.org) are also identified by
     a coloured flag, according to the service
            
Crosswalk
   - escrow transactions get a crosswalk on the street, something that "helps" the side crossing/transaction completion
      
Tree
   - when no fee is paid to the miners, it doesn't help the network, and so a brown tree appears as a reminder of the "environment"
      
Limitations
   - Only the first 24 inputs/outputs will be represented
   - Max building height is 4 btc


Special thanks to @bitcoinmom, @JVianaZ, @zonkism and @RussHarben for their endless patience, precious advice and good will helping me in this fun project.

There are so many different services available that it's hard to choose/trust one.
I'm asking for opinions/feedback from experienced users who can help me in this area.

I'm looking for webhosting + domain, a simple package with basic features and not too expensive.
Thanks

Do you know any service that compares live altcoin prices from various exchanges?
Thanks

When a miner creates a valid block to add to the blockchain, does the miner include the reward transaction in the block himself?
Can a block without a reward transaction be considered valid and added to the blockchain?
Thanks

[Resumo das opiniões:]

Boas pessoal!

Tenho andado a trabalhar numas traduções Bitcoin_Inglês / Bitcoin_Português e gostava de ouvir a opinião dos membros da comunidade que já cá andam há mais tempo que eu,
relativamente a alguns termos. Eu pessoalmente prefiro por vezes usar o termo correcto em inglês do que usar uma tradução em português,
pois muitas vezes acabar por sair fora do contexto e/ou parecer que foi só mesmo para traduzir...

Digam da vossa alma: traduzir, não traduzir, adaptar, ...?

Miner - Mineiro? (este por mim ainda passa...)
Mining - Mineração? (este já arranha um bocado...)
Pool - (este não faço a mínima, não gosto da piscina, os brazucas chamam-lhe poço)
Faucet - torneira?
Pairing - emparelhamento?
Exchange - (a wiki diz bolsa de valores?!, casa de câmbio parece-me fugir um pouco...)
Escrow - escrivão ou notário ou fica assim?

Se tiverem alguma outra palavra que se lembrem que possa causar alguma dúvida, "postem" sff.

Obrigado a todos
