什么是比特币的优点


Rising fees on the Bitcoin network contributed to a push by some in the community to create a hard fork to increase the blocksize.[11] This push came to a head in July 2017 when some members of the bitcoin community including Roger Ver felt that adopting BIP 91 without increasing the block-size limit favored people who wanted to treat bitcoin as a digital investment rather than as a transactional currency.[12][13] This push by some to increase the block size met a resistance. Since its inception up to July 2017, Bitcoin users had maintained a common set of rules for the cryptocurrency.[12] Eventually, a group of bitcoin activists,[14] investors, entrepreneurs, developers[12] and largely China-based miners were unhappy with Bitcoin's proposed SegWit improvement plans meant to increase capacity and pushed forward alternative plans for a split which created Bitcoin Cash.[15] The proposed split included a plan to increase the number of transactions its ledger can process by increasing the block size limit to eight megabytes.[12][13]

  MD5还广泛用于操作系统的登陆认证上,如Unix、各类BSD系统登录密码、数字签名等诸多方。如在UNIX系统中用户的密码是以MD5(或其它类似的算法)经Hash运算后存储在文件系统中。当用户登录的时候,系统把用户输入的密码进行MD5 Hash运算,然后再去和保存在文件系统中的MD5值进行比较,进而确定输入的密码是否正确。通过这样的步骤,系统在并不知道用户密码的明码的情况下就可以确定用户登录系统的合法性。这可以避免用户的密码被具有系统管理员权限的用户知道。MD5将任意长度的“字节串”映射为一个128bit的大整数,并且是通过该128bit反推原始字符串是困难的,换句话说就是,即使你看到源程序和算法描述,也无法将一个MD5的值变换回原始的字符串,从数学原理上说,是因为原始的字符串有无穷多个,这有点象不存在反函数的数学函数。所以,要遇到了md5密码的问题,比较好的办法是:你可以用这个系统中的md5()函数重新设一个密码,如admin,把生成的一串密码的Hash值覆盖原来的Hash值就行了。

Bitcoin Cash was launched in August 2017, as a direct response to small block sizes on the Bitcoin code. 1MB block sizes were not meeting the demand of the growing community, so a group of dissatisfied crypto enthusiasts decided to create a ‘hard fork’ of the Bitcoin blockchain, with an increased 8MB block size. No one person currently takes credit for the token’s creation; rather it is attributed to a de-centralized group of developers.

从广义上来看,网络交换机分为两种:广域网交换机和局域网交换机。广域网交换机主要应用于电信领域,提供通信用的基础平台。而局域网交换机则应用于局域网络,用于连接终端设备,如PC机及网络打印机等。从传输介质和传输速度上可分为以太网交换机、快速以太网交换机、千兆以太网交换机、FDDI交换机、ATM交换机和令牌环交换机等。从规模应用上又可分为企业级交换机、部门级交换机和工作组交换机等。各厂商划分的尺度并不是完全一致的,一般来讲,企业级交换机都是机架式,部门级交换机可以是机架式(插槽数较少),也可以是固定配置式,而工作组级交换机为固定配置式(功能较为简单)。另一方面,从应用的规模来看,作为骨干交换机时,支持500个信息点以上大型企业应用的交换机为企业级交换机,支持300个信息点以下中型企业的交换机为部门级交换机,而支持100个信息点以内的交换机为工作组级交换机。 [3] 

是一个USDT Cryptocurrency


Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.

There are two factions of bitcoin supporters, that support large blocks or small blocks.[20] The Bitcoin Cash faction favors the use of its currency as a medium of exchange for commerce while the Bitcoin-supporting faction view bitcoin's primary use as that of a store of value.[20] Some Bitcoin supporters like to call Bitcoin Cash “Bcash,” “Btrash,” or simply a scam, while Bitcoin Cash advocates insist that their implementation is the pure form of Bitcoin.[20]
