Dave Collins 1973aa5fd5 A few nitpicks with recent getrawmempool updates. 
This commit addresses a few nitpicks in the recent getrawmppol update
which populates the starting and current priority fields.

In particular:

- Move the new calcInputValueAge function before the function which
  invokes it so it is consistent with the rest of the mempool code
- Double space after periods for consistency
- Correct the comments for calcInputValueAge to indiciate that inputs
  which are in the the memory pool count as zero toward the value age
  rather than the incorrect claim that that the overal input value age is
  zero when one of them does
- Rename endingPriority to currentPriority to match the RPC field and its
  actual function
- Make the comment about using zero when input transactions can't be found
  for some reason more accurate since there can be (and frequently is)
  more than one input transaction

btcd

[Build Status] (https://travis-ci.org/conformal/btcd)

btcd is an alternative full node bitcoin implementation written in Go (golang).

This project is currently under active development and is in a Beta state. It is extremely stable and has been in production use for over 6 months as of May 2014, however there are still a couple of major features we want to add before we come out of beta.

It properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as Bitcoin Core. We have taken great care to avoid btcd causing a fork to the block chain. It passes all of the 'official' block acceptance tests (https://github.com/TheBlueMatt/test-scripts) as well as all of the JSON test data in the Bitcoin Core code.

It also relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block. It ensures all transactions admitted to the pool follow the rules required by the block chain and also includes the same checks which filter transactions based on miner requirements ("standard" transactions) as Bitcoin Core.

One key difference between btcd and Bitcoin Core is that btcd does NOT include wallet functionality and this was a very intentional design decision. See the blog entry here for more details. This means you can't actually make or receive payments directly with btcd. That functionality is provided by the btcwallet and btcgui projects which are both under active development.

Requirements

Go 1.2 or newer.
