BITCOIN TRANSACTIONS

Bitcoin Transactional properties:

Transactions are Irreversible: 

Once a transaction has been confirmed, it cannot be reversed by anybody (no matter how highly ranked in the world such as United States president) or institution (such as banks, mining factories). If you send money to someone bitcoin wallet, you have sent it. No one can help you, if you should in case you were scammed or perhaps stolen from your PC by a hacker.

Pseudonymous: 

Neither transactions or accounts are connected to real-world identities. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters. While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the actual identity of users who owns the addresses.

Secure: 

Bitcoin funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptography and the magic of big numbers makes it impossible to break this scheme. But, do not forget your login details.

Fast and global:  

Transaction is propagated nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent of your physical location. It doesn‘t matter if I send Bitcoin to my neighbor or to someone on the other side of the world.

Permissionless: 

You don‘t have to ask anybody to use cryptocurrency. It‘s just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper.

BITCOIN SIMPLY EXPLAINED

What is Bitcoin & how does it work?

Bitcoin is a crytocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin blockchain network without the need for intermediaries. Bitcoin emerged in 2008 just after Occupy Wall Street accused big banks of misusing borrowers’ money, duping clients, rigging the system, and charging boggling fees. Bitcoin pioneers wanted to put the seller in charge, eliminate the middleman, cancel interest fees, and make transactions transparent, to hack corruption and cut fees. They created a decentralized system, where you could control your funds and know what was going on. 

Bitcoin has come far in a relatively short time. All over the world, many legit companies and billion dollars businesses accept this currency. Various websites promote and have integrated this as an alternative payment method. It has its application programming interface (API), price index, and exchange rate.

The creator of bitcoin figured out a way to let two entities confidently trade directly with one another, without the need to rely on all these intermediaries. The key is mathematics. As long as we both trust in math, we can be confident the exchange to occur as expected.
Bitcoin uses public key cryptography and an innovative approach to bookkeeping to achieve the authorization, balance verification, prohibition on double spending, delivery of assets and record inalterability described above. And it happens in near real time at no cost.
Cryptography ensures authorization. You need a private key to transact. And your key is complex enough that it would take the best computer longer than the earth has existed to crack it. In other words, it’s essentially unhackable.
