[Bitcoin比特币] Bitcoin官网已于2013.02.19 发布0.8.0版本的钱包软体

Bitcoin官网已于2013.02.19 发布0.8.0版本钱包软体

主要改变就是
支援多核心CPU的多工运算.


另外, 就是0.8.0版本以后所架设的平台,
在未来可以提供给其他人的轻量级的客户端(例如Android APP 应用软体),有更简化与更好的支援度...

这也意味着, ​​将来采用可携式介面如Android APP 应用软体, 想要更加的简化整个作业,
就得靠更多人架设出新版本钱包软体的伺服器才行.

目前只是先做出与简易可携式应用软体的协议而已.
至于未来在简化过后的可携式应用软体的安全度如何,就不得而知了...


目前(2013.02.22),
0.7.x 版本的 占有率达71% ;
而0.8.0 版本刚开放下载, 占有率达4% .

想要尝鲜的或许可以试试,
不急的就等后续的修正版本吧(因为我试着安装新版的, 途中却曾经跳出runtime error的错误讯息)...



==============

PS. 以下是相关说明 与 网路翻译:

http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.0/

Bitcoin-Qt version 0.8.0 are now available from:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.0/

This is a major release designed to improve performance and handle the
increasing volume of transactions on the network.

Please report bugs using the issue tracker at github:
  https://github.com/bitcoin/bitcoin/issues

How to Upgrade
--------------

If you are running an older version, shut it down. Wait
until it has completely shut down (which might take a few minutes for older
versions), then run the installer (on Windows) or just copy over
/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

The first time you run after the upgrade a re-indexing process will be
started that will take anywhere from 30 minutes to several hours,
depending on the speed of your machine.

Incompatible Changes
--------------------

This release no longer maintains a full index of historical transaction ids
by default, so looking up an arbitrary transaction using the getrawtransaction
RPC call will not work. If you need that functionality, you must run once
with -txindex=1 -reindex=1 to rebuild block-chain indices (see below for more
details).

Improvements
------------

Mac and Windows binaries are signed with certificates owned by the Bitcoin
Foundation, to be compatible with the new security features in OSX 10.8 and
Windows 8.

LevelDB, a fast, open-source, non-relational database from Google, is
now used to store transaction and block indices. LevelDB works much better
on machines with slow I/O and is faster in general. Berkeley DB is now only
used for the wallet.dat file (public and private wallet keys and transactions
relevant to you).

Pieter Wuille implemented many optimizations to the way transactions are
verified, so a running, synchronized node uses less working memory and does
much less I/O. He also implemented parallel signature checking, so if you
have a multi-CPU machine all CPUs will be used to verify transactions.

New Features
------------

"Bloom filter" support in the network protocol for sending only relevant transactions to
lightweight clients.

contrib/verifysfbinaries is a shell-script to verify that the binary downloads
at sourceforge have not been tampered with. If you are able, you can help make
everybody's downloads more secure by running this occasionally to check PGP
signatures against download file checksums.

contrib/spendfrom is a python-language command-line utility that demonstrates
how to use the "raw transactions" JSON-RPC api to send coins received from particular
addresses (also known as "coin control").

New/changed settings (command-line or bitcoin.conf file)
-------------------------------------------------- ------

dbcache : controls LevelDB memory usage.

par : controls how many threads to use to validate transactions. Defaults to the number
of CPUs on your machine, use -par=1 to limit to a single CPU.

txindex : maintains an extra index of old, spent transaction ids so they will be found
by the getrawtransaction JSON-RPC method.

reindex : rebuild block and transaction indices from the downloaded block data.

New JSON-RPC API Features
-------------------------

lockunspent / listlockunspent allow locking transaction outputs for a period of time so
they will not be spent by other processes that might be accessing the same wallet.

addnode / getaddednodeinfo methods, to connect to specific peers without restarting.

importprivkey now takes an optional boolean parameter (default true) to control whether
or not to rescan the blockchain for transactions after importing a new private key.

Important Bug Fixes
-------------------

Privacy leak: the position of the "change" output in most transactions was not being
properly randomized, making network analysis of the transaction graph to identify
users' wallets easier.

Zero-confirmation transaction vulnerability: accepting zero-confirmation transactions
(transactions that have not yet been included in a block) from somebody you do not
trust is still not recommended, because there will always be ways for attackers to
double-spend zero-confirmation transactions. However, this release includes a bug
fix that makes it a little bit more difficult for attackers to double-spend a
certain type ("lockTime in the future") of zero-confirmation transaction.

===========

Google翻译如下:
Bitcoin的Qt版本0.8.0现在可以从:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.0/

这是一个重大的发布,旨在提高性能和处理
在网络上的交易量增加。

请报告错误使用的问题跟踪在github:
  https://github.com/bitcoin/bitcoin/issues

如何升级
--------------

如果你正在运行一个老版本,将其关闭。等待直到它已完全关闭(这可能需要几分钟,老版本),然后运行安装程序(在Windows上)或只是复制过来/应用程序/:Bitcoin的QT间期(在Mac上)或bitcoind / Bitcoin的QT(在Linux上)。

当您第一次运行在升级后重新建立索引的过程将是开始,将采取的任何地方,从30分钟到几个小时,这取决于你的机器的速度。

不兼容的改变
--------------------

此版本不再保持一个完整的指数的历史交易ID默认情况下,所以想找一个任意交易使用getrawtransaction
RPC调用将无法正常工作。如果你需要的功能,您必须运行一次与-txindex = 1 REINDEX重建块的环比指数(见下文的详细详细信息)。


改进
------------

Mac和Windows二进制文件进行签名与证书所拥有的Bitcoin的基金会,以兼容OSX 10.8, Windows 8 的新的安全功能。

LevelDB,从谷歌,一个快速的,开放源码的,非关系型数据库,现在用于存储交易和块指数。 LevelDB的效果要好得多
速度更快的机器上缓慢的I / O和一般。 Berkeley DB是现在唯一的使用的wallet.dat文件(公共的和私人的钱包钥匙和交易
与您相关的)。

彼得Wuille实施了许多的优化,还可以有其他的方式交易验证,所以运行时,同步节点使用更少的工作记忆和做
要少得多I / O。他还实施了平行的签名检查,所以如果你有一个多CPU机器上所有的CPU将被用来验证交易。


新功能
------------

“布鲁姆过滤器”支持的网络协议只发送有关交易轻量级的客户端。

的contrib的/ verifysfbinaries是一个shell脚本,以验证二进制下载在sourceforge上还没有被篡改。如果你有能力,你可以帮助每个人的下载更安全的运行,偶尔来检查PGP下载文件的校验签名反对。

contrib的,/ spendfrom是一个Python语言的命令行实用程序,演示了如何使用“原始交易”JSON-RPC API来发送收到特别的硬币地址(也被称为“硬币”控制)。

新的/改变的设置(命令行或bitcoin.conf的文件)
-------------------------------------------------- ------

dbcache:控制使用LevelDB内存的。

面值:控制使用多少个线程来验证交易。默认的数量在你的机器上的CPU,使用PAR = 1限制到一个单一的CPU。

花txindex:老保持一个额外的索引,事务ID,所以他们会被发现JSON-RPC的getrawtransaction方法。

REINDEX重建块指数和交易指数从下载的数据块。

新的JSON-RPC API的特点
-------------------------

lockunspent / listlockunspent允许锁定一段时间内的交易输出
它们不会被略去由其他进程可能访问相同的钱包。

ADDNODE方法/ getaddednodeinfo方法,而无需重新启动连接到特定的同行。

importprivkey现在需要一个可选的布尔参数(默认为true)来控制是否或不重新扫描blockchain的交易后导入一个新的私钥。

重要的错误修正
-------------------

隐私泄漏:用“变”输出的位置,在大部分的交易是不随机化,网络分析的交易图,以确定用户的钱包更容易。

零确认的交易漏洞:接受零确认交易(交易还没有被列入块)的人,您不信任仍然是个不推荐,因为总是会有攻击者的方法
花零确认交易。但是,此版本包含一个错误解决这个问题使攻击者花多一点点困难某些类型(在未来lockTime“”)的零确认交易。
