General One of the biggest benefits of having IP cameras is being able to access them from the internet. Many of us have smartphones, iPads or netbooks that we take with us and it would be great to check in on the place, a pet or the elderly while at work, in a coffee shop or while traveling. Some cameras have 2 way audio, so you can even talk to the person or pet.

All following currencies would use this proof of work concept in their code. Simply put, his digital form of currency was a work of art. It used cryptography and proof of work functions just as described by Nick Szabo.

The whole code was released as open source for anyone to see and work on in Bitcoin was the first currency of its kind. Each transaction between Bitcoin users was designed in a peer-to-peer method, meaning that all transactions were direct and without an intermediary.

Each transaction is then authenticated and verified multiple times by other computers on the network. The more time passes since the occurrence of the transaction, the more validated it becomes.

It is estimated that once a transaction has been verified 6 times, its validity is equivalent to a 6 month old credit card transaction. Because Bitcoin has no repository or single administrator, and since all of the code used for its own functionally is open source, it is considered to be a truly decentralized system.

The Bitcoin community itself makes decisions on what needs to be implemented in the code and what needs to be rectified. In order for Bitcoin to work correctly, each version of the Bitcoin Core software has to be compatible with each other, so everyone has to make the decision regarding all updates to the software, otherwise those who do not agree with the update will not be able to be a part of the Bitcoin network.

Furthermore, since all of the code is open source, it is practically impossible to shift any power over Bitcoin to a single user or a group of users because this part of the code would be identified quickly and brought to light, making most of the users very unhappy with an attempt to centralize the currency.

Satoshi Nakamoto has claimed to be a man living in Japan who was born on the 5th April, However, Nakamoto has always been somewhat secretive about his identity. In fact, it is unclear to this day whether they are a real person or a pseudonym.

Many people speculate that Nakamoto is actually a group of developers who worked together to jump start the Bitcoin project and then disbanded when it took off. Nakamoto worked on the Bitcoin system up until December ofat which point he handed over the network alert key and the source code repository to Gavin Andresen while distributing some of the key domains linked to Bitcoin amongst notable members of the Bitcoin community.

Afterwards, his involvement with the project ceased.

The father of Bitcoin was able to not only code an exceptionally well built system, but also found clever ways to ensure his work was validated and not misunderstood for some sort of a scheme by others. For example, Nakamoto left a message inside this first manually altered code.

The clever use of this simple message is overlooked by many, and it dictates that the first block was mined no earlier than January 3rd, This is extremely important because the whole Bitcoin system is designed to run and validate itself from the previously mined blocks, so giving a valid timestamp which can be authenticated by a simple headline title to the first block was genius.

Afterwards, all blocks used the previous block for reference. It should also be noted that the timestamps on the subsequent blocks indicate that Nakamoto did not mine the first blocks in an attempt to keep them for himself and make profit this way.

Yes, Nakamoto was awarded Bitcoins as he was the first and a sole miner for some time, but this continued only for about 10 days after the launch of the Bitcoin network.

The only thing that Nakamoto used his Bitcoins for was a few test transactions. Starting from around mid-January ofthose Bitcoins were left unspent. Blockchain This is all fun and peachy, but how exactly are all the transactions made by Bitcoin users kept in check?

Well, luckily Satoshi Nakamoto thought of a rather ingenious way to handle transactions and making them all transparent at the same time. Simply put, whenever a user sends a certain amount of Bitcoins to another user, a third user verifies this transaction and publicly notates it in a ledger which is accessible by anyone.

The more times each transaction is verified, the more secured it becomes. The idea behind the blockchain comes with two main principals. The first is easy to understand, make all the transactions public thus allowing complete transparency over all transactions and the ability to cross reference or double check each transaction if necessary.

Recording each transaction in a public ledger also prevents this information from being duplicated. This way every transaction is unique in its own way, which successfully eliminates transaction fraud and other financial crimes.

Yep, it truly is that secure. In fact, many other online currencies and representations of digital value have started using blockchain as a method to prevent unfair transactions. However, having a general understanding of the blockchain gives you the ability to fully comprehend the security and stability that blockchains bring to the table.
