Bitcoin is the world’s first virtual digital currency underpinned by a completely decentralized blockchain technology also known as the Distributed Ledger Technology (DLT). Bitcoin was first created in 2009 by an anonymous identity of Satoshi Nakamoto. Bitcoin allows for peer-to-peer transactions and is completely free of any third-party involvement like financial institutions or central banks. The Bitcoin’s blockchain network maintains a history of all the transactions made and facilitates instant funds transfer with minimal transaction fees required to cover the cost of network operation. The total supply of Bitcoin is fixed at 21 million coins and its smallest fractional unit is called as Satoshi. Each Satoshi is a hundred millionth of a Bitcoin which means 100,000,000 Santoshi = 1 BTC. Bitcoins are generated by a process known as ‘mining’ which involves solving of complex mathematical algorithms. The miners involved in the mining process look after the Bitcoin network security and validate each transactions taking place on the network. Bitcoin can be exchanged with other digital currencies or fiat currencies. Bitcoin is used as a means of payment by over 100,000 vendors and merchants.

When people talk about the price of Bitcoin, they are referring to the current price at which Bitcoin is changing hands. Since Bitcoin is a purely speculative asset, this price is determined by how little sellers are willing to charge and how much buyers are willing to pay. Even then, the price of Bitcoin can vary across exchanges like Coinbase and Binance or currencies because of market inefficiencies

Here goes a screenshot from my e-mechanical workstation; although and as you can see we are half way routing the traces but progressing. I also have the BOM or other layers if you need to see anything in particular. You think you can help us market this product? we'd like to compete with Intel (and Bitmad lol) for a Pro Turn-Key Crypto Solution. You in?

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。


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.

(展开全部)   London-based Millionairess Epifania (Sophia Loren) is attracted to Dr. Kabir (MD from Delhi and PhD from Calcutta), who is more intent on treating patients. When she persists, he confides in her that he had made a commitment to his late widowed seamstress mother that he will wed any woman who will manage to survive on just Rs.500/-, for 90 days. She finds out that this sum is equivalent to just 35 shillings but readily accepts this challenge. She also informs him that her late father had also imposed a condition that she must wed a male who will turn £500 into £15000 within the same period. Epifania then finds employment with an Italian firm, ends up re-organizing, and turning up the firm's profits. At the end of 90 days, she goes to meet Kabir and discovers that he has not only given all the money away but also has no interest whatsoever in marrying her.


Bitcoin (BTC) is the world’s first decentralized digital currency and payment system and is by far the most known and valuable cryptocurrency. It was created in 2009 by an anonymous person or group called Satoshi Nakamoto. Bitcoin enables transactions to be sent peer-to-peer without passing through a central authority. The transactions are recorded on a decentralized public ledger called the blockchain and each payment acquires a small transaction fee to cover the cost of the network. The total supply of Bitcoin is 21 million and it’s smallest unit of bitcoin is called a Satoshi, it’s a hundred millionth of a bitcoin – 0.00000001 BTC. The creation of Bitcoin’s is happening through mining. Miners have the task to validate transactions and keep the network secure. Their efforts are rewarded by new minted Bitcoins and transactions fees. Bitcoin can be exchanged for fiat or other cryptocurrencies, products and services. Over 100,000 merchants and vendors accepts bitcoin as a payment.
Bitcoin Cash (BCH) is hard fork (a community-activated update to the protocol or code) of Bitcoin that took effect on August 1st, 2017 that increased the block size to 8MB, to help the scale the underlying technology of Bitcoin.Nov 16th 2018: BCH was hard forked again and split into Bitcoin SV and Bitcoin ABC. Bitcoin ABC became the dominant chain and took over the BCH ticker as it had more hashpower and majority of the nodes in the network.
