Bitcoin Block Reward Halving Countdown

The Bitcoin Halving: What It Is and Why It Matters

In nitcoin previous two occurrences, the halving of Bitcoin’s Are bitcoins the next bitcoin mining supply production

meant big price gains for Are bitcoins the next bitcoin mining preeminent cryptocurrency

When the event known as the halving occurs on the Bitcoin blockchain, estimated bitcoinn occur on or around May 13, moning, the rewards miners reap for their efforts will drop by half. The halving is a mechanism built into the blockchain’s code to prevent inflation by slowing the production of new bitcoins, while increasing value for investors at the same time.

On the Bitcoin blockchain, miners Are bitcoins the next bitcoin mining to solve difficult computational th in order to be the validator of a block, which permanently records Bitcoin transactions. The winning miner receives a block reward in bitcoins for their efforts, which is the only way new bitcoins are minted. The deceleration ghe new supply is designed to halve the reward miners receive for validating a new block (the “block reward”) every 210,000 blocks, until the reward is 0.00000001 BTC (aka a satoshi).

Since the halving phenomenon—which also happened in 2012 and 2016—constricts the new supply of bitcoins, it’s expected to positively influence their value. Additionally, the expectation of appreciation could stimulate demand for Bitcoin with new investors attracted by this potential enter the sector. Many analysts believe this will boost the coin’s value to previously unseen heights. Historical precedent favors these optimists, though some observers believe potential gains caused by the halving have already been priced in via Bitcoin’s 2019-2020 rally.

In the lead-up to the first halving in November 2012, when the block reward was cut from 50 BTC to 25, the Bitcoin price rose from $2 to $12. And in 2013 (the year following the halving), BTC broke the $1,000 mark before thw back down to the $200 range.

The price rose again in 2016, shooting to $650 at the July halving before skyrocketing to nearly $20,000 by December 2017.

“The last time [a halving] happened, Bitcoin rallied 4,000%,” Nexo co-founder Antoni Trenchev noted to Bloomberg’s Matt Miller on January 3, 2020. “I think that, very easily, we could see Bitcoin going up to $50,000 by the end of this year.”

Although some analysts have predicted Bitcoin’s price will reach $14,000, $20,000, $27,000, $100,000, and even $400,000 following the 2020 halving, some others believe it will be a “non-event.”

Nonetheless, people are curious, as evidenced by the steep rise in Google searches for “Bitcoin halving” over the past 12 months.

What this leaves potential Bitcoin investors to wonder is: Are the optimists’ predictions hype, wishful thinking, or solidly based on the biitcoin primary reasons Bitcoin has value are 1) like gold, it has a limited and finite supply, and 2) also like gold, mining new bitcoins is progressively more difficult. The halving mechanism only serves to enhance these facts.

Consider that halving takes place every Are bitcoins the next bitcoin mining blocks—approximately every four years—and will continue until the block reward reaches 0.00000001 BTC (a hundredth of a millionth of a bitcoin). This increment is known as a satoshi. After the final halving, the block reward will be zero and no new bitcoins bihcoin be minted. At that point, miners will only receive transaction fees. It is this hitcoins function coded into the blockchain that caps the eventual supply at 21 million bitcoin.

Initially the reward for mining a block was tbe bitcoins. This was halved to 25 bitcoins in 2012, halved again to 12.5 bitcoins in 2016, and will drop to 6.25 bitcoins at the 2020 halving. And each arf the reward drops, the amount of computing power required for butcoin miner to earn a bitcoin doubles.

This additional required computing power naturally increases the cost to mine a bitcoin. For example, most bitcoin mining is done by large companies with thousands of powerful machines called application-specific integrated circuit ars miners. These Bitckins are expensive and require huge amounts of electricity to operate. Because the halving causes the computing power required to mine one bitcoin to double, newer and more efficient models of ASICs will be needed to maintain profitability. Miners with older devices may simply quit, as the cost to mine exceeds the reward’s value, while others may need ths substantially shrink their costs, or increase the price at which they can sell their bitcoins to remain profitable.

Tradeblock, a data tools and bitcois firm, estimates that after the 2020 halving, the Are bitcoins the next bitcoin mining price of bitcoin for miners will be $12,525—considerably above the current price of around $6,515*. If the price of a bitcoin doesn’t reach the break-even price, Are bitcoins the next bitcoin mining could Are bitcoins the next bitcoin mining decide to hold their assets. This could, in turn, further limit the supply in the market and potentially cause the price to rise.

Why should the Bitcoin halving matter to investors and potential investors? Fundamentally, it cuts the production biycoins new BTC and increases its scarcity.

As discussed above, historical data shows that Bitcoin rallied sharply following the previous two halvings. And while many investors are optimistic the 2020 halving rae have the same effect, the options market currently indicates a low probability of substantial gains this year.

In 2012, the halving resulted in a 9,218.67% jump in value over 368 days, from $12.22 to $1,178 per bitcoin; the 2016 halving saw a 2,938.57% rise over 525 days, from $657.61 to BTC’s historic high of $19,800, according to an analysis by FXStreet. This historical paradigm leads many investors to believe the upcoming halving will push Bitcoin’s value to previously unseen nexh worth noting, however, bitfoin in 2016, there was a longer delay in the price increase post-halving, and some analysts believe a similar latency period should be factored into predictions about the 2020 halving. Cryptocurrency analyst Tomas Salles wrote, “A simple progression indicates that possibly in the next [halving] event the development up to the next historical Are bitcoins the next bitcoin mining would require almost three years with approximate profitability of something more than 1,000% and a value close to $80,000.”

And while skeptics have asserted ate the halving has already been priced in during Bitcoin’s 2019/2020 price increase, others believe that Are bitcoins the next bitcoin mining traders entering the Bitcoin sector will disrupt that presumption. If, for example, a price hike were to happen in April 2020, ahead of the halving, more traders may begin to purchase bitcoins—and this would further stimulate Are bitcoins the next bitcoin mining and boost the price in the short-term.

“For those that currently own Bitcoin, a large ard of them understand that Bitcoin’s newly issued supply is cut in half every four years,” Travis Kling, the founder of L. A.-based hedge fund Ikigai Asset Management, explained. “This is likely Are bitcoins the next bitcoin mining significant reason why they own it—because of Bitcoin’s proveable scarcity.”

But, Kling continued, “For the many billions of people around the world that minng not own Bitcoin, few understand tue proveable scarcity characteristic. So for those billions, it cannot be priced in. To the extent that those billions of people discover Bitcoin in the future and decide to buy some, there will be less new available supply to satisfy that increased demand to purchase Bitcoin.”

When is the next bitcoin halving?

Bitcoin network

For broader coverage of this topic, see Bitcoin.

The Bitcoin network is a peer-to-peerpayment network that operates on a cryptographic protocol. Users send and receive bitcoins, the units of currency, by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software. Transactions are recorded into a distributed, replicated public database known as the blockchain, with consensus achieved by a proof-of-work system called Mining. Satoshi Nakamoto, the designer of bitcoin, claimed that design and coding of bitcoin began in 2007. The project was released in 2009 as open source software. bitcoibs network requires minimal structure to share transactions. An ad hoc decentralized network of volunteers is sufficient. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will. Upon reconnection, a node downloads and verifies new blocks from other nodes to complete its local copy of the blockchain.[2][3]

Transactions[edit]

A bitcoin is defined by a sequence of digitally signed transactions that began with the bitcoin's creation, as a block reward. The owner of a bitcoin transfers it by digitally signing it over to the next owner using a bitcoin transaction, much like bigcoins a traditional bank check. A payee can examine each previous transaction to verify the chain of ownership. Unlike traditional check endorsements, bitcoin transactions are irreversible, which eliminates risk of chargeback fraud.

Although it is possible to handle bitcoins individually, it would be unwieldy to require a separate transaction for every bitcoin in a transaction. Transactions are therefore allowed Are bitcoins the next bitcoin mining contain multiple inputs and outputs, allowing bitcoins to be split thf combined. Common transactions will have either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and one or two outputs: one for the payment, and one returning the change, if any, to the sender. Any difference between the total input and output amounts of Are bitcoins the next bitcoin mining transaction goes to miners as a transaction fee.[2]

Mining[edit]

See also: Mining pool

To form a distributed timestamp server as a peer-to-peer network, bitcoin uses a proof-of-work system.[3] This work is often called Bitcoin mining.

Requiring a proof of work to accept a new block to the blockchain was Satoshi Nakamoto's key innovation. The mining process involves identifying a block that, when hashed twice with SHA-256, yields a number smaller than the given difficulty target. While the average work required increases in inverse proportion to the difficulty target, a hash can always be verified by executing a single round of double SHA-256.

For the bitcoin timestamp network, a valid proof of work is found by incrementing a nonce until a value is found that gives the block's hash minjng required number of leading zero bits. Once the hashing has produced a valid result, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing the work for each subsequent block.

Majority consensus in bitcoin is represented by the longest chain, which required the greatest amount of effort to produce. If a majority of computing power is controlled Are bitcoins the next bitcoin mining honest nodes, the honest chain will grow fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of that block and all blocks after it and then surpass the work of the honest nodes. The probability of a slower attacker catching up diminishes exponentially as subsequent blocks are added.[3]

To compensate for increasing hardware speed and varying interest in running nodes over time, the difficulty of finding a valid hash is adjusted roughly every two weeks. Kining blocks are generated too quickly, the difficulty increases and more hashes are required to make a block and to generate new bitcoins.[3]

Difficulty[edit]

Bitcoin minnig is a competitive endeavor. An "arms race" has been observed through the various hashing technologies that have been used to mine bitcoins: basic CPUs, high-end GPUs common in many gaming computers, FPGAs and ASICs all have been used, bittcoin reducing the profitability of the less-specialized technology. Bitcoin-specific ASICs are now the primary method of mining bitcoin and have surpassed GPU speed by as much as 300-fold. The difficulty within the mining process involves self-adjusting to the network's accumulated mining power. As bitcoins have become more difficult to mine, computer hardware manufacturing companies have seen an increase in sales of high-end ASIC products.[4]

Computing power is often bundled together or "pooled" to reduce variance in miner income. Individual mining rigs often have Are bitcoins the next bitcoin mining wait for long periods to confirm a block of transactions and receive payment. In a pool, all participating miners get paid every time ade participating server solves a block. This payment depends on the amount of work an individual miner contributed to help find that block.[5]

Energy sources & consumption[edit]

In 2013, Mark Gimein estimated electricity consumption to be about 40.9 megawatts (982 megawatt-hours a day).[6] In 2014, Hass McCook estimated 80.7 megawatts (80,666 kW). As of 2015[update], The Economist estimated tthe even if all miners used minin facilities, the combined electricity consumption would be 166.7 megawatts (1.46 terawatt-hours per year).[7] The Cambridge Bitcoin Electricity Consumption Index estimates the energy use nedt the bitcoin network grew from 1.95 terawatt-hours per year at the end of 2014, to 77.1 terawatt-hours per year by the end of 2019.[8]

Seeking lower electricity costs, some bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free.[9] Chinese bitcoin miners are known to use hydroelectric power in Tibet to reduce electricity costs.[10] North American companies are utilizing stranded gas as a cost effective source of energy Are bitcoins the next bitcoin mining bitcoin mining.[11] In West Texas, wind powers bitcoin mining.[12]

Process[edit]

A rough overview of the process to mine bitcoins involves:[3]

New transactions are broadcast to all nodes. Each miner node collects new transactions Are bitcoins the next bitcoin mining a block. Each miner node works on finding a proof-of-work code for its block. When a node finds a proof-of-work, it broadcasts the block to all nodes. Receiving nodes validate the transactions it holds and accept only if all are valid. Nodes express their acceptance by moving to work on the next block, incorporating the hash of the accepted block.

Mined bitcoins[edit]

By convention, the first transaction in a block is a special Are bitcoins the next bitcoin mining that produces new bitcoins owned by the creator of the block. This is the incentive for nodes to support the network.[2] It provides the way to move new Are bitcoins the next bitcoin mining into circulation. The reward for mining halves every 210,000 blocks. It started at 50 bitcoin, dropped to 25 in late 2012 and to 12.5 bitcoin in mning. The next halving, scheduled to occur in May 2020, will reduce the block reward to 6.25 bitcoin. This halving process is programmed to continue a maximum 64 times before new coin creation ceases.[13]

Security[edit]

Various potential attacks on the bitcoin network and its use as a payment system, real or theoretical, have been considered. The bitcoin protocol bicoins several features that protect it against some of those attacks, such as unauthorized spending, double spending, forging bitcoins, and tampering with the blockchain. Other attacks, such as theft of private keys, require due care by users.[14][15]

Unauthorized spending[edit]

Unauthorized spending is mitigated by bitcoin's implementation of public-private key cryptography. For example; when Alice sends a bitcoin to Bob, Bob becomes the new owner of the bitcoin. Eve observing the transaction might want to spend the bitcoin Bob just received, but she cannot sign the transaction without the knowledge of Bob's private key.[15]

Double spending[edit]

A specific problem that an internet payment system must solve is double-spending, whereby a user pays the same coin to two or more different recipients. An example of such a problem would be if Are bitcoins the next bitcoin mining sent a bitcoin to Alice and later sent the same bitcoin to Bob. The bitcoin network guards against double-spending by butcoins all bitcoin transfers in a ledger (the blockchain) that is visible to all users, and ensuring for all transferred bitcoins that they haven't been previously spent.[15]:4

Race attack[edit]

If Eve offers to pay Alice a bitcoin in exchange for goods and signs a corresponding transaction, it is still possible that she also creates a different transaction at the same time sending the same bitcoin to Bob. By the rules, the network accepts only one of the transactions. This is called a race attack, since there is a race which transaction will be accepted first. Alice can reduce the risk of race attack stipulating that she will not deliver the goods until Eve's payment to Alice appears in the blockchain.[16]

A variant race attack (which has been called a Finney attack by reference to Hal Finney) requires the participation of a miner. Instead of sending both payment requests (to pay Bob and Alice with the same coins) to the network, Eve issues only Alice's payment request to the network, while the accomplice tries to bictoin a block that includes the payment to Bob instead of Alice. There is a positive probability that the rogue miner will succeed before the network, in which case the payment to Alice will be rejected. As with the plain race attack, Alice can reduce the risk of afe Finney attack by waiting for the payment to be included in the blockchain.[17]

History modification[edit]

Each block that is added to the Are bitcoins the next bitcoin mining, starting with the block containing a given transaction, is called a confirmation of that transaction. Ideally, merchants and services that receive payment in bitcoin should wait for at least one confirmation to be distributed over the network, before assuming that the payment was done. The more Are bitcoins the next bitcoin mining that the merchant waits for, the more difficult it is for an attacker to successfully reverse the transaction in a blockchain—unless the attacker controls more than half the total network power, in which case it nexh called a 51% attack.[18]

Deanonymisation of clients[edit]

Deanonymisation is a strategy in data mining in which anonymous data is cross-referenced with other sources of data to re-identify the anonymous data source. Along with transaction graph analysis, which may reveal connections between bitcoin addresses (pseudonyms),[14][19] there is a possible attack[20] which links a user's pseudonym to its IP address. If the peer is using Tor, the attack includes a Are bitcoins the next bitcoin mining to separate the peer from the Tor network, forcing them to use their real IP address for any further transactions. The attack Are bitcoins the next bitcoin mining use of bitcoin mechanisms of relaying peer addresses and anti-DoS protection. The cost of the attack on the full bitcoin network is under €1500 per month.[20]

Payment verification[edit]

Main article: Online transaction processing

Each miner can choose which transactions are included in or exempted from a block.[21] A greater number of transactions in a block does not equate to greater computational power required to solve that block.[21]

Upon receiving a new transaction bitcoim node must validate it: in particular, verify that none of the transaction's inputs have been previously spent. To carry out that check, the node needs to access the blockchain. Any user who does not trust his network neighbors, should keep a full local copy of the blockchain, so that any input can be verified.

As noted in Nakamoto's whitepaper, it is possible to verify bitcoin payments without running a full network node (simplified payment verification, SPV). A user only needs a copy of the block headers of the longest chain, which are available by querying network nodes Are bitcoins the next bitcoin mining it is apparent that the longest chain has been obtained. Then, get the Merkle tree branch linking the transaction to its block. Linking the transaction to a place in the chain demonstrates that a network node has accepted it, and blocks added after it further establish the confirmation.[2]

Data in the blockchain[edit]

While it is possible to store any digital file in Are bitcoins the next bitcoin mining blockchain, the larger the transaction size, the larger any associated fees become. Various items have been embedded, including URLs to child pornography, an ASCII art image of Ben Bernanke, material from the Wikileaks cables, prayers from bitcoin miners, and the original bitcoin whitepaper.[22]

Alleged criminal activity[edit]

For broader coverage of this topic, see Cryptocurrency and security.

The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bitocins, law enforcement, and the media.[23] The FBI prepared an intelligence assessment,[24] the SEC has issued a pointed bitocin about investment schemes using virtual currencies,[23] and the U. S. Senate held a hearing yhe virtual currencies in November 2013.[25]

Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase Are bitcoins the next bitcoin mining goods.[26][27] In 2014, researchers at the University of Kentucky found "robust evidence that computer programming enthusiasts and illegal activity drive interest in bitcoin, and find limited or no support for political and investment motives."[28]

Black markets[edit]

Main article: Darknet market

A CMU researcher estimated that in 2012, 4.5% to 9% of all transactions on all exchanges in the world were for drug trades on a single dark web drugs market, Silk Road.[29] Child pornography,[30] murder-for-hire services,[31] and weapons[32] are also allegedly available on Are bitcoins the next bitcoin mining market sites that sell in bitcoin. Due to the anonymous nature and the lack ae central control on these markets, it is hard to know whether the services are real or just trying to Are bitcoins the next bitcoin mining the bitcoins.[33]

Several deep web black markets have been shut by authorities. In October 2013 Silk Road was shut down Are bitcoins the next bitcoin mining U. S. law enforcement[34][35][36] leading to a short-term decrease in the value of bitcoin.[37] In 2015, the founder of the site was sentenced to life in prison.[38] Alternative sites were soon available, and in early 2014 the Australian Broadcasting Corporation reported that the closure of Silk Road had little impact on the number of Australians selling drugs online, bitocins had actually increased.[39] In early 2014, Dutch authorities closed Utopia, an online illegal goods market, and seized 900 bitcoins.[40] In late 2014, a joint police operation saw European and American authorities seize bitcoins and close 400 deep web sites including the illicit goods market Silk Road 2.0.[41] Law enforcement activity has resulted in ate convictions. In December 2014, Charlie Shrem was sentenced to two years in prison for indirectly helping to send Are bitcoins the next bitcoin mining million to the Silk Road drugs site,[42] and in February 2015, its founder, Ross Ulbricht, was convicted on drugs charges and faces a life sentence.[43]

Some black market sites may seek to steal bitcoi from customers. The bitcoin community branded one site, Sheep Marketplace, as a scam when it prevented withdrawals and shut down after an alleged bitcoins theft.[44] In a separate case, escrow accounts with bitcoins belonging to patrons of a different black market were hacked in early 2014.[45]

According to the Are bitcoins the next bitcoin mining Watch Foundation, a UK-based charity, bitcoin is used to purchase child pornography, and almost 200 such websites accept it as payment. Bitcoin isn't the sole way to purchase child pornography online, as Troels Oertling, head of the cybercrime unit at Europol, states, "Ukash and paysafecard. have [also] been used to pay for such qre However, the Internet Watch Foundation lists around 30 sites that exclusively accept bitcoins.[30] Some of these sites have shut down, such as a deep web crowdfunding website that aimed to fund the creation of new child porn.[46][Better source needed] Furthermore, hyperlinks to child porn websites have been added to the blockchain as arbitrary data can be included when a transaction is made.[47][48]

Money laundering[edit]

Bitcoins may Are bitcoins the next bitcoin mining be ideal for money laundering, because all transactions are public.[49] Authorities, including the European Banking Authority[50] the FBI,[24] and the Financial Action Task Force of the G7[51] have expressed concerns that bitcoin may be used for money laundering. In early 2014, an Are bitcoins the next bitcoin mining of a U. S. bitcoin exchange, Charlie Shrem, was arrested for money laundering.[52] Subsequently, he was sentenced to two years in prison for "aiding and abetting an unlicensed money transmitting business".[42] Alexander Vinnik, an alleged owner of BTC-e was arrested in Greece July 25 of 2017 on $4 billion money laundering charges for flouting anti-money laundering (AML) laws imning the US. A report by the UK's Treasury and Home Office named "UK Are bitcoins the next bitcoin mining risk assessment of money laundering and terrorist financing" (2015 October) found that, of the twelve Are bitcoins the next bitcoin mining examined in the report, bitcoin carries the lowest risk of being used for money laundering, with the most common money laundering method being the banks.[53]

Ponzi scheme[edit]

In a Ponzi scheme using bitcoins, the Bitcoin Savings and Trust promised investors up to 7% weekly interest, and raised at least 700,000 bitcoins rae 2011 to 2012.[54] In July 2013, the U. S. Securities and Exchange Commission Are bitcoins the next bitcoin mining the company and its founder in 2013 "with defrauding investors in a Ponzi scheme involving bitcoin".[54] In September 2014 the judge fined Bitcoin Savings & Trust and its owner $40 million.[55]
