For those new users of bitcoin and the vast cryptocurrency world its every pointer to the right direction in understanding and using it. The reason it moves back is because Bitcoin mining difficulty tends to rise over time, especially as Bitcoin prices do. For starters, I recommend Moon bitcoin moonbit.
How this digital currency works and why it’s so controversial
A bit of history — The Bitcoin was invented by a man or a group using the pseudonym of Satoshi Nakamoto and having stayed anonymous. Satoshi Nakamoto launched the first version of Bitcoin in and retired gradually in favor of other developers contributing to the project. His first successor as lead developer was Gavin Andresen. The main bitcoin implementation is now maintained by many developers. No one has had any contact with Satoshi Nakamoto since mid Prerequisites — The Bitcoin protocol is mainly based on technologies available and used prior to its appearance, including:. Asymmetric Cryptography: a very popular cryptographic technology that allows in particular to identify the author of a message: Each user has a public and a private key.

The cryptocurrency one of many is at the center of a complex intersection of privacy, banking regulations, and technological innovation. Today, some retailers accept bitcoin, while in other jurisdictions, bitcoin is illegal. Cryptocurrencies are lines of computer code that hold monetary value. These lines of code are created by electricity and high-performance computers. Cryptocurrency is also known as digital currency. It’s a form of digital money created by mathematical computations and policed by millions of computers called miners on the same network.

Asymmetric Cryptography: a very popular cryptographic technology that allows in particular to identify the author of a message: Each user has a public and a private key. The private key only known to the user is used to encrypt a message that can be decrypted using the public key so the user can be identified as the author of the message.
Cryptographic Hash: a function that creates a short fingerprint of a message or file, unique and non-reversible. Bitcoin mining consists in finding a particular result produced by this function to ensure that the minor has a certain computing power. Bitcoin is a virtual currency: its has no representation in the real world. Some currencies were represented by gold stocks the dollar before Its value is determined only by the exchange market which gives Bitcoin a value to make it a medium of exchange and as a speculative invesment.
Bitcoin is thus similar to gold: except for a few cases electronic, esthetic Thoses properties are also present in Bitcoin. Bitcoin units can not be created by an entity or state and are limited to 21 million units called bitcoins No capital B — the writing with a capital B refers to the technology.
Each bitcoin is divisible into million units called Satoshis. This makes a total of 21 x 10 14 of indivisible units. The following explanation present how Bitcoin works step by step by highlighting the problem behind the idea of a decentralized currency and the solutions brought by the Bitcoin. This explanation is a simple approach of the mechanisms behind Bitcoin and does not constitute a complete or rigorous explanation.
Issue — With a decentralized currency, how to safely identify the person sending money? The protocol uses the asymmetric cryptography. Bob wants to send 1 bitcoin to Alice so he uses his private key to sign the message «I, Bob sends 1 bitcoin to Alice». Then, using his public key, anyone can verify that it is How does free bitcoin work that sent this message and he can’t claim. Issue — How to prevent Bob from duplicating this message and sending an unlimited number of times that bitcoin?
We give this bitcoin a serial number, eg The message will be now «I, Bob is sending 1 bitcoin No. Actually, a bitcoin does not have a serial number but is traceable from its generation until this last use, which makes it to uniquely identifiable. Issue — How to verify that Bob does indeed have this bitcoin No. Each user has a «ledger» called the blockchain which lists all the transactions and therefore who owns which bitcoin.
Bob is sending the message «Me Bob is sending 1 bitcoin No. She then sends to everyone Bob’s message and a second message indicating to everyone that she accepts this bitcoin.
Everyone then update their blockchain. Issue — How ensure that Bob does not send the same message simultaneously to two people who do not have time to update their the blockchain and therefore do not know the bitcoin No. This is where the bitcoin miners come into play. Alice verifies that Bob has the bitcoin No. They check that the transaction is valid and spread the message «Ok, Bob has the bitcoin No. Issue — If Thomas is a bitcoin miner, how to prevent it from spreading thousands of times the messages «Ok, Bob has the bitcoin No.
To handle this network manipulation problem Bitcoin uses the system of «Proof-of-work». The operation of spreading the message «Ok, Bob has the bitcoin No. The gain of such an attack is negligible in comparison to its cost. Issue — What motivates miners to verify transactions? Minors are rewarded with new bitcoins created at a steady, predictable rate. The rate will reach a final total of 21 million in After that date, the miners will only be rewarded with low commissions earned on every transaction validated.
