LedgerX - An Institutional Trading and Clearing Platform with full regulatory approval from the U.S. Commodity Futures Trading Commission (CFTC) to trade and clear options on bitcoin.
Bitcoin[a] submitted by
) is a cryptocurrency
. 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 network without the need for intermediaries.
Transactions are verified by network nodes
) through cryptography
and recorded in a public distributed ledger
called a blockchain
. Bitcoin was invented by an unknown person or group of people using the name Satoshi Nakamoto
and was released as open-source software
Bitcoins are created as a reward for a process known as mining
. They can be exchanged for other currencies, products, and services.
Research produced by University of Cambridge
estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet
, most of them using bitcoin.
Bitcoin has been criticized for its use in illegal transactions, its high electricity consumption, price volatility, thefts from exchanges, and by reputable economists stating that "it should have a zero price".
Bitcoin has also been used as an investment, although several regulatory agencies have issued investor alerts about bitcoin. Mining
is a record-keeping service done through the use of computer processing power
Miners keep the blockchain consistent, complete, and unalterable by repeatedly grouping newly broadcast transactions into a block
, which is then broadcast to the network and verified by recipient nodes.
Each block contains a SHA-256 cryptographic hash
of the previous block,
thus linking it to the previous block and giving the blockchain its name.
To be accepted by the rest of the network, a new block must contain a proof-of-work
The system used is based on Adam Back
's 1997 anti-spam
The PoW requires miners to find a number called a nonce
, such that when the block content is hashed
along with the nonce, the result is numerically smaller than the network's difficulty target.
:ch. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is the ascending natural numbers: 0, 1, 2, 3, ...
:ch. 8) before meeting the difficulty target.
Every 2,016 blocks (approximately 14 days at roughly 10 min per block), the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.
:ch. 8Between 1 March 2014 and 1 March 2015, the average number of nonces miners had to try before creating a new block increased from 16.4 quintillion to 200.5 quintillion.
The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted.
As new blocks are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks (also called confirmations
of the given block) increases.
