Researchers have pointed out at a "trend towards centralization". Although bitcoin can be sent directly from user to user, in practice intermediaries are widely used.:220–222 Bitcoin miners join large mining pools to minimize the variance of their income.:215, 219–222:3 Because transactions on the network are confirmed by miners, decentralization of the network requires that no single miner or mining pool obtains 51% of the hashing power, which would allow them to double-spend coins, prevent certain transactions from being verified and prevent other miners from earning income. As of 2013 just six mining pools controlled 75% of overall bitcoin hashing power. In 2014 mining pool Ghash.io obtained 51% hashing power which raised significant controversies about the safety of the network. The pool has voluntarily capped their hashing power at 39.99% and requested other pools to act responsibly for the benefit of the whole network.
Bitcoin has both advantages and disadvantages. Advantages include the ability to choose your own fees, easily accept payment from people who do not have credit cards, and send payment without tying your personal information to the transaction. Disadvantages include that it is a very new form of currency, acceptance of it is still limited, and the anonymity of transactions means you do not know with whom you're dealing.
Though each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed – only their wallet IDs. While that keeps bitcoin users’ transactions private, it also lets them buy or sell anything without easily tracing it back to them. That’s why it has become the currency of choice for people online buying drugs or other illicit activities.
The other primary validation method is PoS. Rather than using a ton of electricity in a competition to solve equations, the PoS method awards the owners of virtual coins the opportunity to validate transactions in a deterministic fashion. In even plainer terms, the more coins you own of a virtual currency operating on the PoS model, the more likely you are to be chosen to validate blocks and add to the blockchain.
Nakamoto is believed to have created the first blockchain database and has been the first to solve the double spending problem other digital currency failed to. While Bitcoin’s creator is shrouded in mystery, his Wizard of Oz status hasn’t stopped the digital currency from becoming increasingly popular with individuals, businesses, and even governments.
Lawbreakers have to hide and camouflage the money gained from their exploits. Currently this is done with fake bank accounts, gambling, and offshore companies, among other stratagems. There are a lot of concerns regarding the transparency of cryptocurrency transactions. But, all of the necessary regulatory elements, such as identifying parties and information, records of transactions and even enforcement can exist in the cryptocurrency system.
In the past when a claim is made, all checks would be carried out by humans, which can be time-consuming and leaves room for human error. This will become unnecessary, as checks to ensure that all criteria have been met, and can be done automatically using the Blockchain. Once all obligations are fulfilled, the resulting payout is automatic. This can all be done using minimum human involvement.
A blockchain is a record-keeping system where multiple sources validate an entry before it gets added to the chain of data. Once data has been added, it cannot be changed and the record is distributed to multiple places within the network. Adding a new record (known as a block) to the blockchain sequence requires verification by multiple members connected to the blockchain network. These blocks of data are all linked to one another forming the chain. All transactions are public to those in the blockchain, but all individual identities are hidden.
