Details Editorial Reviews About the Author Henning Diedrich has been called IBM's most knowledgeable guy in blockchain, and a thought leader in this field.He was named architect at the IBM blockchain group, writing the first white paper for IBM's Open Blockchain project and is the official IBM liaison to the Ethereum Foundation's core development teams, helping to harden Ethereum for industrial use.Henning frequently gives deeply technical presentations as well as highly inspirational keynotes on blockchain topics around the world.Check out his talks on YouTube.“I got into blockchain because I became fascinated by the technology, the same as with language design, database architecture or coding in the first place.In blockchain tech, many domains coalesce that I have worked in.I started programming age 12 hacking computer games, and always remained passionate about performance and whatever resembles 'AI'.I worked in fintech, distributed databases and functional programming, domains that are all of special significance for the future of blockchain at this point.

I created a compiler and virtual machine for the insurance industry, which an eternity before it, looked eerily like Bitcoin's VM.I started programming crypto stuff a decade ago.I am evangelizer for the best distributed, high-velocity database out there, VoltDB, and suffered with them through different stabs at solving distribution.Which is what the blockchain community re-lives right now.In a way, it's all coming together for me in blockchains.I had to fall for it.“ Browse the New York Times best sellers in popular categories like Fiction, Nonfiction, Picture Books and more.See more Product details Paperback: 360 pages Publisher: CreateSpace Independent Publishing Platform; 1 edition (September 8, 2016) Language: English ISBN-10: 1523930470 ISBN-13: 978-1523930470 Product Dimensions: 5 x 0.8 x 8 inches Shipping Weight: 14.9 ounces (View shipping rates and policies) Average Customer Review: (17 customer reviews) Amazon Best Sellers Rank: #1,641 in Books (See Top 100 in Books) in Books > Business & Money > Economics > Money & Monetary Policy in Books > Business & Money > Economics > Digital Currencies in Books > Computers & Technology > Internet & Social Media > E-Commerce If you are a seller for this product, would you like to suggest updates through seller support?

The Bancor Foundation says its tokens will do away with the exchanges on which cryptocurrencies are usually traded.Instead of having a middleman that matches buyers and sellers, Bancor tokens will do the matching themselves, using automatically executed rules called smart contracts that are coded into the tokens.This could pave the way for new investment vehicles, such as a Bancor token that functions like an exchange-traded fund holding a basket of cryptocurrencies, or tokens that are pegged to a particular exchange rate.dogecoin spaceInvestors believe the Bancor token could act like a supra-national currency for cryptocurrencies—indeed, the term “bancor” was coined by John Maynard Keynes and EF Schumacher for just such a currency in the 1940s.But the Bancor token sale didn’t go smoothly.Hot ICOs have been selling out in seconds, so crypto investors have been feverishly pushing their way in.Some have paid thousands of dollars in transaction fees to get their ether accepted first.

Interest in Bancor was so great—boosted by the revelation, just before the sale started, that Tim Draper, a prominent venture capitalist, was involved—that the ethereum network became congested.A popular wallet provider, MyEtherWallet, reported hours-long delays for transactions to be completed.This was because the Bancor Foundation had recommended buyers use it to participate in the offering.While the ethereum network clogged as users bid ever higher fees to ensure their money was accepted, services like MyEtherWallet struggled to cope with the flood of new users.“With these ICOs you are essentially asking a service to scale from maybe 10% capacity to 1,000% capacity in the course of less than a minute,” says Taylor Monahan, a co-founder of the wallet service.“Every single person presses the send button at the same time.” This led to another problem.In the past, ICOs have been criticized for selling out quickly to large holders of cryptocurrencies.Mindful of this, and worried that the network congestion would make it even harder than usual for small investors to get a shot, the Bancor Foundation kept the offering open for longer than planned.

But as a result it also collected 150,000 ether ($51 million) more in funds than intended.That angered investors who did get in early, and who say they were promised the funds would be capped.“The initial supply was inflated by 58% by changing the rules,” one investor on the Bancor project’s public Slack team, who goes by Kasper23, told Quartz.“And that hurts all investors that got in before the [initial target] was reached.” More worryingly, the freeze-up of the ethereum network showed that it can’t handle sudden surges in transaction volume.That’s very similar to the problem plaguing its forebear, bitcoin; ethereum was supposed to be more resilient.Ethereum processes about 50% more transactions than bitcoin does every 10 minutes, thanks to its rules that make miners confirm transactions at more frequent intervals.It also side-steps the dispute at the heart of bitcoin—how to increase its “block size” and thus transaction capacity—by allowing the number of transactions processed by each miner to be increased or decreased by a small degree by the miner itself.

This means ethereum blocks can grow or shrink dynamically, whereas bitcoin’s blocks are stuck with an arbitrary limit.Even those clever features haven’t been enough to prevent the ethereum network from seizing up during high-traffic events, like a hot ICO.“This wasn’t the only one, there was at least one other ICO that caused congestion, for at least two to three hours,” says Nick Johnson, a developer at the Ethereum Foundation who works on the protocol.Johnson notes that ethereum has other mechanisms to reduce the effects of traffic jams, such as the ability for ICO issuers to set a maximum price on transactions.This is what Bancor did, and it allows ethereum users not participating in the ICO to get their own transactions confirmed—so long as they pay a price above the limit.Johnson also points out that unlike bitcoin, which is suffering from prolonged congestion due to its block-size limit, ethereum is being overwhelmed only sporadically, during unusually high periods of activity.
