Here's Why It's Not Ready for the Big Time The price of a bitcoin has soared above $17,000, but it'll cost you $19 to process a single transaction within 10 minutes. To the moon! The phrase is the battle cry of true believers in cryptocurrency bitcoinand charts of its price in recent weeks point directly heavenward. Yet beyond a batch of newly minted crypto-millionaires, the digital assets recent bull run has also exposed long-standing weakness in the underlying technology that could crimp bitcoins long-term viability. Bitcoin was a gift to the world from Satoshi Nakamoto, a pseudonymous person or persons who laid out the design in a 2008 white paper . The paper complained that conventional financial institutions create unnecessary friction: banks and other mediators pass on costs as transaction fees that make small casual transactions impractical. Nakamoto said bitcoin would change that, by employing a peer-to-peer network backed by unbreakable math to verify transactions, removing the need for centralized institutions. The paper doesnt use the term, but its a clear reference to the concept of micropaymentsthe idea that very small digital payments could change the economics of the internet, or help people in the developing world . Nine years later, Nakamotos invention has been immensely successful. A single bitcoin will set you back more than $17,500; the price has risen 17-fold since January. But the currency has not introduced a new era of economic enlightenment greased with tiny transactions. Why not? Continue reading >>
7 Transactions Per Second? Really?
The general wisdom seems to be that the Bitcoin network can currently sustain 7 transactions per second. Bitcoin advocates often worry that this will be a limiting factor when credit card processing networks can handle several orders of magnitude more transactions in the same time, but what are the actual statistics related to Bitcoin transaction processing? Our Bitcoin mine train may not be seeing its hashing engines running away quite as much as they were earlier this year, but are we heading for other problems instead? Before we can really think about Bitcoin transaction processing we need to look at how its transaction processing has evolved over time. Let's start by looking at the numbers of transactions per day for approximately the last 4 years: As with all of our Bitcoin rollercoaster rides there are highs and lows, but the trend is generally up over time. It may not be the sort of exponential growth seen with the global hash rate but it's hard to argue that the number of transactions hasn't been going up. It's looking much more erratic as we move to the right but we've seen that sort of thing before and it's usually because the percentage swings are the same but the larger numbers makes things look worse. One solution is to look at this on a log scale: With this view the growth may not look quite as impressive but we can see that the daily variations really aren't anything new. What else can we see? Well we're not really getting to more than about 80k transactions per day right now, or just under 1 per second. On the surface it would seem that we ought to be quite some way from hitting any limits. A Quick Aside: The Bitcoin Network Gets Tired On Sundays? Did you notice that the noise over the last year looks surprsingly periodic? Zooming in on this we can see Continue reading >>

A Blockchain That Handles Millions Of Transactions Per Second?
A Blockchain that Handles Millions of Transactions per Second? December 22, 2017, 10:12:31 AM EDT By David Floyd Anyone who tried to send some bitcoin over the past few days and found themselves paying a fee of $20 or moreonly to wait hours for the transaction to confirmknows about blockchains' scalability issues. Bitcoin cash was forked from the main chain to try to speed things up a bit, but the 30-something transactions per second the new cryptocurrency could reasonably process pale in comparison to Visa's 50-something thousand. Which is why, if Kochava founder and CEO Charles Manning is right, the product his company is building could attract a lot of attention in blockchainland. He expects XCHNG, a smart contract platform Kochava hopes will disrupt the digital advertising industry, to process millions of transactions per second. "Yeah, millions, exactly," Manning told me on a phone call last week, in response to an incredulous request that he repeat the number. "That's what's amazing to me, is that financial services folks often point to their transaction volumes and say, well it really needs to beef up. If you want an example of a very difficult, high-volume ecosystem, it's adtech. Think of every impression as a trade." Processing a transaction in 45 or 50 milliseconds is nothing new for the industry or for Kochava, a six-year old company that, until around two-and-a-half years ago, had nothing to do with blockchain. Maintaining that kind of speed when moving from a centralized model to a decentralized one, though, has so far defied solution. To be sure, XCHNGwhich Manning expects to go live at the beginning of 2019does not rely on proof of work, which would probably preclude even speeds a few orders of magnitude slower than Kochava aims for. XCHNG is its own ani Continue reading >>
Before And After The Great Bitcoin Fork Bridge21
Before and After the Great BitcoinFork Tomorrow on August 1st 2017, at 12:20pm UT, or 8:20am ET, Bitcoin will split into two. One Bitcoin will be known as Bitcoin and enable Segwit2x, supported by most businesses in the community. Another Bitcoin will be Bitcoin Cash, which has lesser support, but is currently trading on futures markets at around 20% of Bitcoins value. If you control the private keys to an address with 1 Bitcoin on July 31st, after this fork event, you will control 1 Bitcoin (BTC) and also 1 Bitcoin Cash (BCC) on two, previously identical but from that point onward divergent cryptocurrency networks. You will own two separate versions of Bitcoin with their own futures and supporters after the fork event. PSA: bridge21 does not anticipate any interruption ofservice Quickly, we do not anticipate any interruption of bridge21s services from Bitcoins hard fork on August 1, 2017. All of our Bitcoin will be stored on addresses where we control the private keys during the fork event, thereby ensuring no loss of funds on either chain. Were also keeping enough Mexican Pesos in reserve so that even if there are significant disruptions to the Bitcoin network, we will still be able to satisfy customer transactions for some time after the fork. Finally, our service doesnt need a specific type of digital currency to win or lose in order to be successful, so we have no horse in the race. Todays blog post is the first half of a before and after piece on the specifics of the Bitcoin hard fork, including an objective look at both sides of the scaling debate. A warning, this post will require some knowledge of Bitcoin to understand, and is unlikely to be enjoyable or even comprehensible to the casual reader. As no one really knows what will happen with the split tomorrow w Continue reading >>
Daily Transactions | Bitcoin.com Charts
The number of transactions included in the blockchain each day Daily Transaction count is one of the most important and controversial metrics for the bitcoin network. Because all confirmed transactions pay a fee, each confirmed transaction represents someone's desire to send a bitcoin transaction instead of any alternative use of that cost. Bitcoin transactions can be executed and automated by software, but this is limited by the bandwidth of the network and required fees. Occasionally large numbers of transactions will be made in a short time interval, leading to long confirmation times and some transactions that may not confirm at all. While some attribute unusually high transaction volume to "spam" transactions, others hold that any transactions following the rules of the network are valid. Because transactions have a real world cost, daily transaction count is one of the best ways to model growth in users of the bitcoin network. Daily transaction count could be manipulated in the short term, but it's difficult to identify plausible motives given the high costs . Continue reading >>
Almost 11 Transactions Per Second! - Bitcoin
Bitcoin becomes massively popular, 100x price increase, blocks fill up, 3-4 tps limit hit, competition for space in the block drives up transaction fees. Rogue splinter group becomes convinced that the block size limit is arbitrary/hindering growth, if only it was removed the price would skyrocket and they could cash out. FUD campaign to gather support and cast doubt on the existing developers, and a spam campaign to max out capacity, forcing the issue. Alts rise rapidly as people 'hedge their bets'. Bitcoin XT, Classic, Unlimited, Emergent Concensus fail to gain support, so they force a miner-supported hard fork. BCash eeks out 15% of the market price and falling. SegWit increases capacity to 11 tps, fees fall, tech is now poised for secondary layers. Am I missing anything? This space moves quickly. I'd quibble with some of the numbers: Per average transactions per block have been around 2100. This translates to a rate of 3.5/sec (and network is at or close to capacity, since there's a backlog) Segwit increases the limit, except that people either can't or don't know how to generate segwit transactions (due to lack of wallet features). So a very low percentage (under 1%) of transactions is currently segwit. Source: Segwit adoption is required for fees to stay low as historical transaction load appears to be repeatedly exceeding the 3.5 transaction/sec limit of the non-segwit blocks. Source: Yeah you missed the bit where a bunch of CEOs are gonna fire the devs Yes, you forgot /r/btc will still blindly tell you that fees are still 100000000000 sat/B. Give it a couple days when the miners switch back to Bitcoin cash. The fees will be crazy. It's so easy to send 100x spam transactions.. 100x bigger block won't just make blockchain 100x bigger, but also it will just make i Continue reading >>
Game Of Coins: Btc Vs Bch Comparison In Charts
Game Of Coins: BTC VS BCH Comparison In Charts Now that Bitcoin Cash shows signs of wanting to be the contender for the cryptocurrency throne, it's nice to see the reality in a few charts. JustCryptoNews.com reports for you. First, we've got the average number of blocks found every hour, in the last 30 days. Bitcoin shows a pretty-much constant rate of around six blocks per hour, while Bitcoin Cash blocks fluctuated heavily. There were times that more than 50 new BCH blocks were validated in a single hour. And that's not always something good. Now, have a look at the average block sizes. This is a highly political issue inside the bitcoin community, as "big blockers" argue that bitcoin should be used not only as a store value but also as a means of payment, which in turn means many transactions per second and thus the need for larger blocks. As you see Bitcoin, blocks remain at 1MB or a little more while Bitcoin Cash actual blocks are way smaller than that, even though the protocol supports blocks up to 8MB. Nevertheless, during last weekend's BCH rally, the blocks of the throne contender became larger than 1MB and briefly reached and surpassed the 2MB mark. We know what you might be thinking when looking at the last chart. What happened to Segwit-enabled blocks? Well, Segwit adoption rose at >10% but at the moment segwit transactions seem to be stuck at around 12%. And we don't expect much to change, as long as Coinbase and other large exchange do not yet support it. Having mentioned the poor adoption rate of Segwit, it should be noted that Bitcoin Cash does not support Segwit. Bitcoin proponent Charlie Lee believes this is because "miners need a coin to keep mining using AsicBoost" a controversial technology in mining rigs by Bitmain. Note that Bitmain has denied usi Continue reading >>
Scalability - Bitcoin Wiki
[Note: This page is seriously outdated and largely unmaintained; due to past incidents of edit-warring it has not been subject to much peer review.] A Bitcoin full node could be modified to scale to much higher transaction rates than are seen today, assuming that said node is running on a high end servers rather than a desktop. Bitcoin was designed to support lightweight clients that only process small parts of the block chain (see simplified payment verification below for more details on this). Please note that this page exists to give calculations about the scalability of a Bitcoin full node and transactions on the block chain without regards to network security and decentralization. It is not intended to discuss the scalability of alternative protocols or try and summarise philosophical debates. Create alternative pages if you want to do that. When techies hear about how bitcoin works they frequently stop at the word "flooding" and say "Oh-my-god! that can't scale!". The purpose of this article is to take an extreme example, the peak transaction rate of Visa, and show that bitcoin could technically reach that kind of rate without any kind of questionable reasoning, changes in the core design, or non-existent overlays. As such, it's merely an extreme example not a plan for how bitcoin will grow to address wider needs (as a decentralized system it is the bitcoin using public who will decide how bitcoin grows) it's just an argument that shows that bitcoin's core design can scale much better than an intelligent person might guess at first. Dan rightly criticizes the analysis presented here pointing out that operating at this scale would significantly reduce the decentralized nature of bitcoin: If you have to have many terabytes of disk space to run a "full validating" n Continue reading >>
Bitcoin Scalability Problem
For a broader coverage related to this topic, see Bitcoin . The bitcoin scalability problem exists because of the limits of the maximum amount of transactions the bitcoin network can process. It is a consequence of the fact that blocks in the blockchain are limited to one megabyte in size.  Bitcoin blocks carry the transactions on the bitcoin network since the last block has been created.  :ch. 2 In contrast to Visa's peak of 47,000 transactions per second,  the bitcoin network's theoretical maximum capacity sits between 3.3 to 7 transactions per second.   The one-megabyte limit has created a bottleneck in bitcoin, resulting in increasing transaction fees and delayed processing of transactions that cannot be fit into a block.  Various proposals have come forth on how to scale bitcoin, and a contentious debate has resulted. Business Insider in 2017 characterized this debate as an "ideological battle over bitcoin's future."  On 21 July 2017 bitcoin miners locked-in a software upgrade referred to as Bitcoin Improvement Proposal (BIP) 91, meaning that the controversial Segregated Witness upgrade activated at block 477,120.  A fork (referring to a blockchain) is what occurs when a blockchain splits into two paths moving forward. Forks on the bitcoin network regularly occur as part of the mining process. They happen when two miners find a block at a similar point in time. As a result, the network briefly forks. This fork is subsequently resolved by the software which automatically chooses the longest chain, thereby orphaning the extra blocks added to the shorter chain (that were dropped by the longer chain). A blockchain can also fork when developers change rules in the software used to determine which transactions are valid.  As per CoinDesk , a h Continue reading >>
Transactions Speeds: How Do Cryptocurrencies Stack Up To Visa Or Paypal?
Transactions Speeds: How Do Cryptocurrencies Stack Up To Visa or PayPal? Transactions Speeds: How Do Cryptocurrencies Stack Up To Visa or PayPal? Cryptocurrency bag holders often boast that their network transaction speeds are faster than mainstream payment methods, such as Visa or Paypal. As cryptocurrencies continue to rise in popularity, it will be important to determine which blockchain payment networks could eventually become the new Visa. While both sides continue to debate their arguments, we jumped through the hard data and created a unique visual to highlight transaction speeds across several different payment networks. We chose to compare the transaction speeds of some of the largest cryptocurrencies by market-cap relative to Visa and PayPal. Each payment network is ranked largest-to-smallest based on the size of their balloon, which equates to the number of transactions per second. The larger the balloon, the more transactions their payment network can process per second. This allows for a clear and concise visual to show once and for all how some of the most popular crytpocurrencies stack up to more traditional payment methods. Ripple Shows Potential, But Visa is Still the King of Speed As you can see, Visa still has the fastest transaction speeds over any other payment networks measured, with 24,000 transactions per second. It was surprising to see Ripple come in second and beat out PayPal by a whopping 1,307 transactions per second. This shows that Ripple may have the capability to be a viable payment solution on a much larger scale. PayPal had 218 million active users during the third quarter of 2017. PayPal is still among the most popular and well-known digital peer-to-peer platforms out there, but Ripples transaction speed dominance could be the key to Continue reading >>

Crypto Vs Visa Can Denarius Compete When It Comes To Transactions Per Second?
Click here to view original web page at themerkle.com Bitcoin and blockchain technology may give us some insight into the future of payment processing but it sure has a long way to go. VISA handles on average around 2,000 transactions per second (tps) and peaks around 4,000 tps during high shopping periods. This is just a fraction of their capacity, which is said to be around 56,000 transactions per second. Paypal, in contrast, handled around 10 millions transactions per day or 115 transactions per second according to data from late 2014. If we set the benchmark for cryptocurrencies at 4,000 transactions per second, where do we stand as of right now? And what kind of speed will Bitcoin or any other cryptocurrency need to handle even 10 percent of the economic transactions done worldwide? Today, the Bitcoin network is restricted to a sustain rate of around 7 transactions per second or a little over 600,000 transactions per day. To put this in perspective, Bitcoin could only handle roughly 5 percent of the transactions that Paypal handles everyday! And what about Altcoins? Is Bitcoin Cash much better at this? When the fork happened on August 1, 2017, Bitcoin Cash was unleashed and touted as a huge improvement over the current Bitcoin algorithm. As for the transactions per second, Bitcoin Cash is capable of handling around 60 transactions per second. This is a huge improvement but we found one coin that can handle more than 20 times the transactions per second of Bitcoin! Transactions per second chart, Bitcoin vs. Denarius. A coin called Denarius [DNR] has been under the radar lately. According to their website and whitepaper, Denarius uses a new proof of work algorithm called Tribus a combination of 3 popular NIST5 algorithms that were created to resist the ability to be Continue reading >>
The Bitcoin Bubble Explained In 4 Charts
Cryptocurrencies have surely been the best-performing asset class of 2017. The crown jewel of the crypto world Bitcoin has run up over 604% year to date. But that pales in comparison to Ethereums 3,562% gain this year. Naturally, these sorts of monstrous returns in such a short period of time spark heated debate. In fact, many financial pundits and crypto advocates have scrambled to argue whether Bitcoin is a bubble or not. So as the financial community takes sides, I decided to dig into Bitcoins tremendous run using nothing but hard data to see whether its in bubble territory or not . (Meanwhile, I highly recommend you download our exclusive special report, Investing in the Age of the Everything Bubble , from Wall Street veteran Jared Dillian.) Bitcoins Performance Dwarfs Tech Stocks Run in the 90s, but This Bubble Is Nowhere Near the Dot-Com Mania The Bitcoin run has drawn comparisons to the dot-com bubble of the late 1990s. While the sentiment and underlying forces of both bubbles may be similar, their performance is a different story. At the beginning of 2015, Bitcoin was trading just above $300. In early November this year, the Bitcoin price topped $7,600. That translates to returns north of 2,200% in a matter of 1,041 trading days. By comparison, the NASDAQ index was up 391% after 1,041 trading days from the start of 1995. Returns on the NASDAQ index peaked just shy of 1,100% after 1,326 trading days. Bitcoins run has far outpaced the tech bubble, and its returns have already dwarfed dot-com mania. Now, crypto advocates argue that Bitcoin has tranformative fundamentals so the returns are justified. I dont deny that blockchain is a transformative technology that will eventually revolutionaize the finance industry. But the mainstream adoption of the Internet in the Continue reading >>
How The Lightning Network Can Resolve Bitcoins Scaling Issues
How the Lightning Network Can Resolve Bitcoins Scaling Issues written by Daniel Frumkin November 28, 2017 If youve followed the biggest news stories of recent months in the cryptocurrency space, then youve likely heard about Bitcoins scalability problems. The Bitcoin Cash hard fork and the canceled SegWit2x hard fork were both conceived as solutions to this issue of scaling the Bitcoin network. This article will be discussing one of the most promising solutions that may eventually be implemented on the Bitcoin blockchain the Lightning Network. For anybody who is invested in Bitcoin, the Lightning Network is one of the most important topics that you should know about. After all, it is the future of Bitcoin. If Bitcoin is to reach mass adoption and go to the moon as many of us hope, it will be in no small part because of the success of the Lightning Network. To understand why this is so important, lets start with the problem that Lightning Network addresses. Blockchains are slow. In its current state, Bitcoins transaction processing speed maxes out at just over 10 transactions per second. However, the historical average is even lower, at about 3 transactions per second. Source: Meanwhile, transaction fees have increased by over 1000% since 2015 . With fees at their current levels, small transactions can often cost more than the actual value being sent, making them infeasible. Source: If Bitcoin is going to be useful in the future as an actual currency and not just a store of value, something has to change. Bitcoin Cash addressed the problem by increasing the blockchains block size from 1 MB to 8 MB. This increased transaction throughput from 3 per second to about 24 per second. As a result, Bitcoin Cash has the same low fees that Bitcoin had from 2009 until 2016, making Continue reading >>
