Bitcoin mining problem resolution
Sep 8, 2014 Bitcoin transactions aren't actually instant. Because each transfer requires a number of confirmations via the mining process, some Bitcoin moves can take minutes or even half an hour. CoinSafe, however, may have created a solution that can process BTC transactions in seconds. CoinSafe, a company Visualize and Download High-Resolution Infographic The Computationally-Difficult Problem Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: This digital currency is mined or generated in a unique way that involves the use of special software to solve problems. Bitcoin mining can be To conclude, Bitcoin mining is an interesting concept that allows users to generate Bitcoins by using their hardware and software to resolve block puzzles. Interested users have the Nov 6, 2017 Each fork seeks to resolve a key point of contention in the bitcoin world: Bitcoin Classic was designed to solve the scalability problem with block size; Bitcoin Gold aims to address the centralization of mining. The creators of Bitcoin Gold changed the bitcoin proof-of-work algorithm from SHA256 to Equihash make bitcoin wallet address Sep 30, 2015 Other issues surfaced with Bitcoin's mining procedure. As the currency has gained value, for example, mining competition has become fiercer, with increasingly specialized computers solving the puzzles ever faster. Courtois, who has found ways to streamline the puzzle-solving process, says that at one
Genesis Mining. 87K likes. The world's leading and most transparent hosted hashpower provider for Bitcoin and Altcoins. Reliable & Customer Oriented. In the meantime we're in the process of ramping up new mining hardware, solving infrastructure issues and are progressing on long overdue user interface updates.Results 1 - 48 of 780 Generation of Bitcoin involves complex problem-solving and/or calculation,Sep 16, 2017 [image] The following guide is a comprehensive tutorial on GPU mining from planning through execution. This is a fairly simple procedure and examples will be given in order to achieve the fastest possible hash litecoin mining windows xp In this post we will try to break down, in simpler terms, the mechanism of blockchain and bitcoin. Readers are assumed to be familiar with a few basic cryptography and blockchain related terms. Today, I'll specifically focus on transaction validation and mining rewards. Transactions are validated by miners by solving Jan 8, 2016 My point was simple, I had to convince everyone in the room that SPV Mining was not only inevitable (if not prevented by a softfork or hardfork) but was the solution to many of the Bitcoin protocol problems, including a future hard fork to scale Bitcoin. One of the problems with Bitcoin at that time was the bitcoin mining block login Jan 15, 2018 The basic problem, as BuzzFeed's Ryan Mac explained in a post headlined “This Is Why Experts Are Calling Kodak's New Bitcoin Scheme A Scam,” is that it gets progressively more difficult to mine more bitcoin. So unless Bitcoin's value increases far above its current level—the classic expectation behind a May 3, 2016 The subject of this article is technology of distributed trustless consensus, for this is the one area in which blockchain systems, like Bitcoin, are indeed a major Proof of work is a requirement that expensive computations, also called mining for reasons which later will become clear, be performed in order to earn bitcoin with amazon Aug 28, 2015 Rather than continuing to work with the developers who maintain Bitcoin's code, Andresen released his solution in the form of an alternative version of the Bitcoin software called BitcoinXT and urged the community to switch over. If 75 percent of miners have adopted his fix after January 11, 2016, it will
Jul 17, 2017 In this lengthy article, I'll attempt to present a comprehensive case as to why miners should oppose Segwit2x by switching to pools that will not signal for Segwit2x. Technically, Segwit is a complex solution to a much simpler problem that will make it difficult for developers to develop for Bitcoin in the future.The solution to this problem is collective action—hooking up with a large group of other miners to form a pool. “Mining bitcoins is analogous to buying lottery tickets. Solving a block is like winning the lottery because a lot of it is essentially random,” Garzik explained. ‟Having more computer power is like buying more lottery hashflare mining pools Jan 4, 2018 It's a problem which affects approximately 500 million people worldwide but not for those who choose Opera 50. We, as the only major browser with an integrated ad blocker, have a built-in solution to keep miners from trespassing onto your machine. After we recently updated the rules of our built-in ad A mathematical problem is linked with each block. Miners are constantly processing and recording transactions as part of the process of competing in a type of race. They race to 'complete the current block' in order to win Bitcoins. When a winning miner is able to solve it, the answer is shared with other mining nodes and it ethereum mining computer Nov 29, 2017 Contentious forks occur when the blockchain bifurcates due to disagreement among miners and users about a change to the Bitcoin rules;; A security failure During 2017, Bitcoin had been dealing with this problem by implementing forks so that the network could resolve the scaling issue in a manner that 3 days ago Availability, and the ever-present fluctuations of supply and demand, are the cause, but this time demand has skyrocketed because of graphics card-powered cryptocurrency mining. It's been years since graphics cards were used en masse for Bitcoin mining, because the hardware arms race meant that bitcoin mining free SUMMARY: While Chelan County PUD ponders whether to charge bitcoin miners and other high- density load dealing with some problems of its own—an indication that disruptive industries aren't immune to . “pursue more expeditious resolution of the issues” with potential customers, and then file a revised tariff.
The Miner's Dilemma - Hacking, Distributed
Jan 6, 2018 “The second someone creates a viable quantum computer, the NP-complete math problems at the heart of Bitcoin mining tech become instantly solvable,” Beath notes. “In other is 'mine all of the remaining Bitcoin instantly. Blockchain May Provide a Sustainable Solution for Fishing by Jeff John Roberts.Nov 16, 2017 A green-energy startup says it can solve bitcoin's surging electricity consumption without boosting pollution, an issue threatening to halt the meteoric rise of the virtual currency. Dec 15, 2017 From the energy sector to the media industry, there seems to be an unquenchable desire to find a problem for which blockchain architecture is a solution. But the fact of the matter is: There is a big problem with bitcoin, and blockchain technology is at the center of that problem. The bitcoin story should be Jan 12, 2018 4,251 students from 383 schools all over Ireland impressed with their curiosity and problem-solving skills. In the bustling RDS, the standard of submissions was inspiring (and more than a little intimidating). yesterday reported on projects that explore filthy pedestrian crossings and an
using their computer's processing power to attempt to find solutions to this problem. Every 10 minutes on average, a new solution is found by someone who then is able to validate the transactions of the past 10 minutes and is rewarded with brand new bitcoins. Essentially, bitcoin mining de-centralizes the currency-issuance Sep 1, 2017 All of these miners seemingly use the same mining pool to generate Bitcoin and they may very well belong to the same organization. It is unclear who owns the devices exactly, but they seemingly all use a Chinese IP address. Thankfully, the miners were taken offline shortly afterward to resolve this issue. Jan 5, 2018 (such as, e.g., Bitcoin or Ethereum) are set by the protocol known as “proof- of-work”, which can be sketched as follows (and is described in more details in the next section): At each point in time, miners try to validate a new block of transactions. This implies solving a purely numerical problem unrelated. Apr 28, 2016 P2P networks, like other distributed systems, have to solve a very difficult computer science problem: the resolution of conflicts, or reconciliation. At the time of writing, mining Bitcoins still costs slightly less in energy and hardware than you can earn by selling the coins you discovered in the process.
Dec 13, 2017 Although he initially believed the code had been designed to force his laptop to try to create bitcoins, other users noted that it had in fact been designed to mine another digital currency, Monero. Mining involves solving complicated mathematical equations to verify crypto-currency transactions.The reality is though, that bitcoin mining is expensive, requires adequate technical knowledge of bitcoin and the mining process, as well as some level of computer skills and possible troubleshooting or problem solving skills. you can tell if someone is new to bitcoin, if they ask you how they can start mining bitcoin. Bitcoin My P.C specs are as follows if needed: i think there's a bitcoin miner virus on my pc - Forum. How to tell if I'm running a bitcoin mining program? Nov 24, 2017 Bitcoin Difficulty – Since the Bitcoin network is designed to produce a constant amount of Bitcoins every 10 minutes, the difficulty of solving the mathematical problems has to increase in order to adjust to the network's Hash Rate increase. Basically this means that the more miners that join, the harder it gets
Dec 7, 2017 Is there any solution? Mati Greenspan, senior market analyst at eToro says yes. “The current bitcoin mining system is no doubt inefficient. This is one of the flaws in the original blockchain and represents a potential scaling issue. We're not at the point that anybody should really be worried and we have Jul 14, 2017 Anyone holding the digital currency bitcoin could soon face some unsettling problems—up to and including financial losses, whipsawing prices and delays in The coins are created by computer farms that "mine" them and verify other users' transactions by solving complex mathematical puzzles. Miners Nov 16, 2017 This is just one possible solution, and it has its faults, due to the still unpredictable nature of discovering the right fees, or predicting the usage of Bitcoin itself: Bitcoin transaction fee estimation is a goldilocks problem wrapped in a future prediction enigma shrouded by a miner mystery. — Jameson Lopp Escrow is touted as a solution for this, but there are almost no working examples. When Butterfly Labs stiffed people on Bitcoin mining equipment, Bitcoiners who paid with filthy fiat via PayPal were able to raise chargebacks and get their money refunded, which many did gleefully;
Mar 7, 2017 In the bitcoin system, because no user is implicitly trusted to verify transactions, all users follow an algorithm that verifies transactions by committing software and hardware resources to solving a problem by brute force (i.e., by solving the cryptographic puzzle). The user who reaches the solution first is Dec 22, 2017 Finally, a browser is doing something to protect users from drive-by crypto-miners. Bitcoin is a solution to a specific problem. That problem was how to That turns out to be a fairly difficult problem, and Bitcoin is one solution to that problem. So Bitcoin is a protocol that Bitcoin transactions are available in a public log generated in a distributed process by people called miners. People think of mining as Dec 8, 2017 I recommend to you read something about IOTA coin which is a solution to all problems which BTC fees, No waiting for a long time for a confirmation from miners, no forks = no fakes cryptos, no confusing in the future similar like everyone sees by the BTC forks and many others advantages IOTA has.
In the simplest terms, as each batch of bitcoins joins the blockchain the ensuing problems become progressively more difficult and more computing power needs to be brought to bear on them. Because of this “mining farms” have sprung up where banks of computers are dedicated to solving these problems. “Miners” are Apr 4, 2017 Bitcoin is a whole process that involves giving command to the home computer so that it can work around the clock and solve proof of work problems. Each bitcoin .. Miners compete with other miners in solving mathematical problems and they work on a block with the help of cryptographic hash functions. Mar 11, 2017 There is a consensus that SegWit is the best solution to this problem if it is accepted; as it will virtually double bitcoin's capacity. Pieter proposed that SegWit would increase blockchain network transactions. SegWit is yet to gain approval because a vocal minority of bitcoin miners is not in support. Dec 17, 2013 It is chipping away at a cryptographic problem, using the input at the top of the screen and combining it with a nonce, then taking the hash to try to find a solution. Solving that problem is a lot easier than solving the block itself, but doing so gets the pool closer to finding a winning nonce for the block.
Dec 14, 2016 Hence the miners are called as book-keepers as the blockchain has list of every transaction processed by the network. Network guardians: Miners also safeguard the network against hacks and validate each transaction. Bitcoin mining gives a probabilistic solution to Byzantine's General problem with the Jan 21, 2015 This asymmetry ensures that the solution to the problem can be used as proof for a certain effort level (proof for some level of resource spending), while the verification is essentially costless. Proof-of-work forms the foundation for the process referred to as Bitcoin min- ing. The term comes from gold mining, So, regarding the "math problems": A miner takes a bunch of recent Bitcoin transactions and bundles them all up into one "block". Because to change it, an attacker would need to supply a new solution for that particular puzzle with your transaction missing and then also re-solve all the other puzzles after Jun 6, 2017 Now, he has taken up the banner of Bitcoin Unlimited, a solution to the scaling issue that would directly increase the code's limit on how much data a block can hold. While this If more than 50 percent of miners were to support Bitcoin Unlimited, they could force a shift in the entire network. Ver, though
“SPV mining” is the solution, not the problem | Bitslog
Dec 11, 2017 Apparently, it is the computational requirements that process the complex cryptographic problems that miners must solve to be rewarded with the cryptocurrency. Just like other notable cryptos such as Ethereum and Litecoin, Bitcoin depends on miners to validate transactions performed in their respective May 3, 2016 Bitcoin is a paperless, bank-less, state-less currency that allows people to pay directly for goods and services. The coins themselves are made by computers solving a set of complex math problems, and people who use their computers to make coins and record transactions are called miners. The value of a Mar 13, 2017 You should also take into account that bitcoin miners generate a fair bit of heat and noise. They aren't usually pleasant to have next to your bed. Additionally, running a bitcoin miner full time can sometimes require a significant amount of babysitting, troubleshooting and problem solving. These things aren't Results 1 - 48 of 1286 New ListingNew Antminer S9 13.5TH/s Bitcoin Miner + AP3W++! *USA SELLER* SHIPS NEXT DAY. Furthermore, I performed a 36 hour stress-test(24-36 hours of running is when hashboard problems become apparent) on the machine to ensure that the hashing boards operate correctly. Pictures 3

Not only do you give up Nov 2, 2017 BTG was created around October 25, as a group of Bitcoin developers and miners executed a hard fork of the Bitcoin blockchain protocol. "Bitcoin Gold is yet another example of crypto forks emerging as a free market solution to a decentralized problem," said Trevor Koverko, CEO of Toronto-based mining Visualize and Download High-Resolution Infographic. The Computationally-Difficult Problem. Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation Aug 4, 2016 This results in longer transaction time for users. Bitcoin's blocks are quickly getting filled up. Without a solution to blockchain congestion problem, transactions on the blockchain will continue to be delayed. To quicken transfer, users can pay miners higher transaction fees to be included in a block sooner.
Jul 4, 2015 Note: this situation has not been fully resolved, and it does not appear that it will be fully resolved anytime soon. Users of the affected Your bitcoins are safe if you received them in transactions confirmed before 2015-07-15 12:00 UTC. However, there The problem is miners creating invalid blocks. Some 21 hours ago The product comes from Bitmain, a hardware company that specializes in cryptocurrency mining rigs. Bitcoin mining works by 'miners' using special software to solve complex math problems that contribute blockchain to the ledger, miners are issued a certain number of bitcoins in exchange for this labor. Jan 15, 2018 How do I calculate my Bitcoin mining profitability? What does hashing mean? What is a Bitcoin mining pool? What does GPU stand for? What is a Bitcoin mining GPU=Graphics Processing Unit It refers to mining with your video card. Generation of Bitcoin involves complex problem-solving and/or calculation Dec 15, 2017 In a report last week, the cryptocurrency website Digiconomics said that worldwide bitcoin mining was using more electricity than Serbia. The country. “If you can come in and suddenly start solving these cryptographic puzzles at the heart of it, you can contribute to the upkeep of the ledger.” You can't trick
Jul 21, 2017 This war may finally have come to an end Thursday night, however, with the adoption of a solution to bitcoin's scaling woes known as "Bitcoin Improvement Plan 91," or BIP 91. For BIPs to be adopted, enough miners—the people who process blocks of bitcoin transaction data—have to "signal" their intent to Mar 2, 2017 Is there a solution to the scaling problem? 5. Moreover, the speed at which Bitcoin miners are likely to process any particular transaction depends directly on the size of the miners' fee, set by the Bitcoin Unlimited is a direct evolution of the previous unsuccessful attempts to resolve the block size debate. Dec 1, 2013 The currency automatically regulates the difficulty of the mathematical problem (adding complexity to the hash value computers need to find) as well as the number of bitcoins received as a reward. If a lot of people are connected to the network to mine for bitcoins the difficulty of solving a block increases Aug 15, 2017 What is Bitcoin Mining? Bitcoin Mining is a computation. This computation is done using computers. It involves trying to find a solution to a complex mathematical problem. Those who solve the problem receive as reward a certain number of bitcoins.
Dec 14, 2017 The solution is yet to be completed, however. It is still difficult to estimate how soon it will be available for fully-fledged Bitcoin mining operations. Maybe there are other several probable solutions to solve the energy consumption issues related to Bitcoin mining, but none are definite at this point in time.Jan 5, 2018 Around five years ago, it no longer made financial sense for individual Bitcoin enthusiasts to invest in mining. The probability of successfully solving a block was past parity with the cost of running the firetrap hobbyist equipment required to play. With China divesting itself of the mining industry, the enormous Mar 22, 2017 The truckers will have a problem with this transition, and this can cause a problem in dealing with the truckers at all. This is similar to what we have here. Wu seems hopeful of a resolution that keeps large mining pools like his in the Bitcoin economic mix. “If we want to solve the problem, we have to talk Okay. Bear with me. This may get technical. Every miner or mining pool puts together a block which is a basket of verified transactions that they want to publish to the public blockchain. Once they have that block they then have a unique "puzzle
7 things you need to know about Bitcoin | PCWorld
Jul 13, 2017 However, any changes require consensus from the miners who create Bitcoins and process transactions, and because it's not in their best incentive to do .. It would be much better to find a genereal solution that fix that problem altogether, instead of finding a solution that works for the next few years and Mar 9, 2017 So far, the bitcoin community has been unable to settle on a solution to a perennial problem plaguing the network—namely, the digital currency's The total value of all transaction fees paid to the virtual miners who power the bitcoin network rose to 270 bitcoins (or about $320,000) on Wednesday, its Dec 20, 2017 Ultimately, the only optimization a bitcoin miner can do is to reduce cost and procure specialized hardware. This has caused bitcoin mining equipment to be manufactured for the exclusive purpose of mining bitcoin or solving the distributed ledger. Arguably, this is wasteful compute, and worse yet the gear It is important to know how blockchain Hashing Is Hashing? Under The Hood Of Blockchain. core principles that go into blockchain creation.
The current block reward of 25 Bitcoins is given to the miner who successfully "mines the block" (finds the appropriate hash). To make any sense of Bitcoin's solution to this problem, you need to understand also what is meant by "distributed timestamp server" and how proof of work hashes can be used to construct this.Jan 23, 2015 We are starting to see Blockchain based disruptive technologies, solving real world problems. Bitcoins are mined. Mining is a computationally intensive process. Mining with CPU and GPU has already gotten to a point where the profitability is almost trivial. The energy consumption is higher than the output Jul 28, 2016 the hardness of the problem so that a solution is moderately hard to find by the totality of miners  in a statistical sense. Let us now recap the two currently main implementations of mining : proof- of-work and proof-of-stake systems. In the context of blockchain-based systems, a proof-of-work  is a non- Jan 14, 2016 Even if a new team was built to replace Bitcoin Core, the problem of mining power being concentrated behind the Great Firewall would remain. Bitcoin has no future whilst it's controlled by fewer than 10 people. And there's no solution in sight for this problem: nobody even has any suggestions. For a
Jul 19, 2017 However, the recent developments on the cryptocurrency market signal that Bitcoin miners are ready to support the change. The upcoming modifications might be able to resolve cryptocurrency's long time scaling issue. Some of the largest Bitcoin miners – AntPool, BitClub, Bixin, , and BitFury, Yes, it's a bit volatile and yes, other cryptocurrencies are a lot easier to mine and a lot cheaper to buy, but the ever-growing number of ways to spend bitcoins – plus the fact In fact, other Bitcoin exchanges such as Bitstamp and BTC-E are still operational, having resolved the issues on their side and resumed processing Jun 16, 2014 Pooled mining could be disincentivized, and though this is incredibly unlikely to happen (it would destroy the financial model the entire cryptocurrency industry is based on) it might be the best long-term solution. This is the type of deep structural problem that could bring Bitcoin down entirely. If Mar 4, 2016 New blocks cannot be submitted to the network without the correct answer - the process of "mining" is essentially the process of competing to be the next to find the answer that "solves" the current block. The mathematical problem in each block is extremely difficult to solve, but once a valid solution is found,
With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past Visualize and Download High-Resolution Infographic.However, this solution requires an important ingredient: the blockchain must be aware of time. In order to solve this problem, Bitcoin requires miners to submit a timestamp in each block, and nodes reject a block if the block's timestamp is either (i) behind the median timestamp of the previous eleven blocks, or (ii) more than 2 Jan 13, 2018 To get new bitcoins, miners use special software to solve math problems. It's a process that gets more and more difficult, requiring ever more powerful computers to crunch the numbers. A lot of electricity is consumed and a lot of heat is generated, making bitcoin an increasingly "dirty" activity that contributes : Block C Avalon6 Bitcoin Miners - 3.5 TH/s: Computers & Accessories.
with a reward for solving the cryptopuzzle. This process is called Bitcoin mining, and, by slight abuse of terminology, we refer to the creation of blocks as block mining. The specific cryptopuzzle is a double-hash whose result has to be smaller than a set value. The problem difficulty, set by this value, is dynamically adjusted.Bitcoin's main contribution amounts to a solution to a variant of the consensus problem—one that does not require participants to have strong identities, but instead The nodes in charge of Bitcoin's transaction processing, also known as miners, form a large and connected peer-to-peer network that together authorizes all May 16, 2013 One of the most common questions about Bitcoin mining. What are Modern Bitcoin miners can do this problem approximatly 1 billion times a second so it might not be worth while to use pen and paper. The sender must provide a solution to a cryptographic problem before the message will be accepted. Aug 28, 2017 Profitability from ETH mining will reduce significantly over the next few months. In the simplest terms, cryptocurrency mining is a process of solving complex math problems. “Miners” are Cryptocurrency mining, including bitcoin and Ethereum, has become increasingly harder for miners to make a profit.
Not worth mining bitcoin if you do it as a hobby, Tech News & Top
Dec 14, 2017 London's Southwark playhouse is now accepting BITCOIN donations. Starbucks responded to Dinkin's tweet, confirming the issue. "As soon as we were alerted of the situation in this specific store last week, we took swift action to ensure our internet provider resolved the issue and made the changes Jun 28, 2017 Then, when they successfully find a solution to the next hash problem and mine a block of bitcoins, something magical happens. They get to add the block they just mined to the end of the existing blockchain — and with it, they include every transaction that was initiated on the bitcoin network since the last Dec 3, 2014 In a new analysis of Bitcoin mining, Ittay Eyal shows that the equilibrium between miners is unstable, and identifies a stable equilibrium that might, as a side effect, reduce the size of open, public mining pools. can break the system. As we will see below, it now turns out that this problem may resolve itself. Nov 13, 2017 The original vision for Bitcoin was that anyone would be able to participate in Bitcoin mining with their personal PCs, earning a bit of extra cash as they In one example presented in the Equihash paper, solving a version of the problem with 700 megabytes took about 15 seconds, while solving the same
Dec 21, 2016 Bitcoin is given to miners as a reward for validating the previous transactions. So how do they do it? Bitcoin mining requires a computer and a special program. Miners will use this program and a lot of computer resources to compete with other miners in solving complicated mathematical problems. About Dec 13, 2017 Did you know that when you're logging into the Wi-Fi at Starbucks, you could have code installed on your laptop that is used to mine for bitcoin? As soon as we were alerted of the situation in this specific store last week, we took swift action to ensure our internet provider resolved the issue and made the Dec 3, 2017 Bitcoin mining is the process of solving some special mathematics problems and getting rewarded with one bitcoin once each problem is solved. The above sentence is almost all people like you and me can understand from bitcoin mining. There are so many unanswered questions about this process:. Dec 15, 2017 This means about 1,800 new bitcoin are currently created per day. But as mentioned, creating a new block is not as simple as verifying transactions. Miners must also solve a complicated maths problem, known as a hash. In simplest terms, users get their computers to guess a number. And this is no small
Oct 21, 2016 The paper predicts that miner incentives will start to go haywire as Bitcoin rewards shift from block rewards to transaction fees, based on theoretical results that of transaction fees between different blocks, and this mitigates the problem somewhat, although it is far from a complete and satisfactory solution.Feb 23, 2014 The main problem with a distributed transaction log is how to avoid inconsistencies that could allow someone to spend the same bitcoins twice. The solution in Bitcoin is to mine the outstanding transactions into a block of transactions approximately every 10 minutes, which makes them official. Conflicting or With Bitcoin you don't have this problem because the system is designed to make Bitcoins to be finite. Only about 21 milion Bitcoins will ever be released (mined). The release of Not a real problem that needs a solution, but you can carry a billion dollars worths of Bitcoins on a memory stick in your pocket. You can't do that Dec 6, 2013 The solution to this problem is to reward people who help validate transactions. In particular, suppose we reward whoever Bitcoin also makes it possible to set aside some currency in a transaction as a transaction fee, which goes to the miner who helps validate it. In the early days of Bitcoin transaction
