Now, if there is no central system, how would everyone in the system get to know that a certain transaction has happened? The network follows the gossip protocol. Think of how gossip spreads. Suppose Alice sent 3 ETH to Bob. The nodes nearest to her will get to know of this, and then they will tell the nodes closest to them, and then they will tell their neighbors, and this will keep on spreading out until everyone knows. Nodes are basically your nosy, annoying relatives.


Whether it’s Bitcoin transactions or data about how a shipment of flowers is making its way from Senegal to the Netherlands, the block is the mechanism that records information to the blockchain. Some people like to compare it to an Excel spread sheet or a Google Doc. Those blocks come together to make up the blockchain, which is the overall digital record of transactions. Every time one is completed, the next can be created. So far, this has been a lot slower than some parts of the internet, partly because certain blockchains need to have every party agree before it’s added in order to help make it transparent and secure. That makes the chain the overall list, a record of all transactions.

Several central banks, including the Federal Reserve, the Bank of Canada and the Bank of England, have launched investigations into digital currencies. According to a February 2015 Bank of England research report, “Further research would also be required to devise a system which could utilize distributed ledger technology without compromising a central bank’s ability to control its currency and secure the system against systemic attack.”
Bitcoin faucets have been around since at least 2011. It is believed that Gavin Andresen owned the first one. They come and go and often enough are just advertising scams – the owners want users on their site so they tempt them with free Bitcoin that never actually materializes because before the users have made enough to “cash out” the site has disappeared.
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]
