This technology has great implications for the financial services industry as well. On implementing a decentralized database or a public registry like blockchain to verify the identities of all parties, no longer will we need to have our transactions stay “pending” for three days. Settlement would be instantaneous since the transaction and settlement would happen simultaneously once the ledger is updated. There are many such use cases.
User fear of 51% attacks can actually limit monopolies from forming on the blockchain. In “Digital Gold: Bitcoin and the Inside Story of the Misfits and Millionaires Trying to Reinvent Money,” New York Times journalist Nathaniel Popper writes of how a group of users, called “Bitfury,” pooled thousands of high-powered computers together to gain a competitive edge on the blockchain. Their goal was to mine as many blocks as possible and earn bitcoin, which at the time were valued at approximately $700 each.
That one google doc’s guy is sort of off in his definition of blockchain to dita…as that is what that scenario is. I worked with a system named Centralpoint also allows for a IFTTT (If this then that) approach to building your own logic engine (or rules engine), which to use Blockchain venacular would be considered Smart Contracts. Examples of this would be when to send someone an email report (business intelligence) or when to trigger a new record entry into your CRM.

Bitcoin mining is the process by which new Bitcoins are generated. When you perfom mining, your computer adds new Bitcoin transactions to the block chain (a public ledger where all Bitcoin transactions are stored) and searches for new blocks. A block is a file that has the most recent Bitcoin transactions recorded in it. When your computer discovers a new block, you receive a certain number of Bitcoins. Currently a block contains BTC 25. This number changes throughout time and gets smaller by the factor 0.5 every four years.

According to a report, as of October 2017, there have been 42 equity investment deals in 2017 alone, totalling $327 mln.

Nakamoto is estimated to have mined one million bitcoins[27] before disappearing in 2010, when he handed the network alert key and control of the code repository over to Gavin Andresen. Andresen later became lead developer at the Bitcoin Foundation.[28][29] Andresen then sought to decentralize control. This left opportunity for controversy to develop over the future development path of bitcoin.[30][29]
