Dünya çapında Bitcoin kullanımı

Bitcoin herkesin, dünyanın heryerine anlık ödeme yollayabilmesini sağlayan deneysel ve merkezi otoriteden bağımsız dijital bir para birimidir. Bitcoin kullanıcıdan-kullanıcıya (p2p) teknolojisine dayanarak merkezi otoriteye ihtiyaç duymadan çalışır: alım satım işlemlerinin yönetimi ve piyasaya para sürülmesi iletişim ağı tarafından kitlesel olarak yürütülür.

Özgün Bitcoin yazılımı Satoshi Nakamoto tarafından MIT lisansıyla yayınlanmıştır. Bu ilk yazılımdan türeyen veya sıfırdan geliştirilmiş diğer birçok kullanıcı yazılımı da açık kaynak lisansı kullanır.

Bitcoin kripto-para-birimi adı verilen, ilk defa 1998 yılında Wei Dai tarafından cypherpunks mail grubunda ortaya atılan bir konseptin ilk uygulamalarındandır. Herhangi bir ülkede ya da sosyo-ekonomik bağlamda mal ve hizmetler için ödeme yapmak ya da borcun geri ödenmesi için kabul gören herhangi bir obje ya da kaydın para olabileceğinden yola çıkan Bitcoin; piyasadaki para miktarının belirlenmesi ve paranın transferi için merkezi bir otoriteye yaslanmak yerine, bu işi kriptografiye devretme fikriyle tasarlanmıştır.

Bitcoin is P2P electronic cash that is valuable over legacy systems because of the monetary autonomy it brings to its users. Bitcoin seeks to address the root problem with conventional currency: all the trust that's required to make it work -- Not that justified trust is a bad thing, but trust makes systems brittle, opaque, and costly to operate. Trust failures result in systemic collapses, trust curation creates inequality and monopoly lock-in, and naturally arising trust choke-points can be abused to deny access to due process. Through the use of cryptographic proof, decentralized networks and open source software Bitcoin minimizes and replaces these trust costs.
  • Bitcoin Transactions are:
    • Permissionless and borderless. The software can be installed by anybody worldwide.
    • Anonymous. Bitcoin does not require any ID to use making it suitable for the unbanked, the privacy-conscious, computers or people in areas with underdeveloped financial infrastructure.
    • Private. When used with care bitcoin can support strong financial privacy.
    • Censorship-resistant. Nobody is able to block or freeze a transaction of any amount.
    • Fast. Transactions can be made almost as fast as data can travel over the Internet.
    • Cheap. Fees can be very very low.
    • Irreversible once settled, like cash. (but consumer protection is still possible.)
    • Online and available 24 hours a day, 365 days per year.

Bitcoin can also be a store of value, some have said it is a "swiss bank account in your pocket".

  • Stored Bitcoins:
    • Cannot be printed or debased. Only 21 million bitcoins will ever exist.
    • Have no storage costs. They take up no physical space regardless of amount.
    • Are easy to protect and hide. Can be stored on a phone, computer, encrypted on a paper backup or memorized in your head.
    • No counterparty risk. If you keep the seed phrase of a bitcoin wallet secret and the transaction has enough confirmations, then nobody can take them from you no matter for what reason, no matter how good the excuse, no matter what.
    • Can be under divided possession with Multisignature. For example with a 2-of-3 multisig scheme there would be three private keys, of which any two is enough to spend the money. Those three keys can be spread anywhere, perhaps in multiple locations or known by multiple people. No other asset does this, for example you cannot hold gold coins under multisig.

Topic central


Q. What is Bitcoin?

A. Bitcoin is a peer-to-peer currency. Peer-to-peer means that no central authority issues new money or tracks transactions. These tasks are managed collectively by the network.

Q. How does Bitcoin work?

A. Bitcoin uses public-key cryptography, peer-to-peer networking, and proof-of-work to process and verify payments. Bitcoins are sent (or signed over) from one address to another with each user potentially having many, many addresses. Each payment transaction is broadcast to the network and included in the blockchain so that the included bitcoins cannot be spent twice. After an hour or two, each transaction is locked in time by the massive amount of processing power that continues to extend the blockchain. Using these techniques, Bitcoin provides a fast and extremely reliable payment network that anyone can use.
