Distributed computing software and network engineers are taking a variety of approaches in designing and building secure, peer-to-peer transactions and distributed ledger systems that solve the lack of scalability and processing efficiency, as well as the tremendous energy consumption, that plague existing blockchain distributed ledger systems. Dcntral.ai founders David Allen Cohen and James Barry figure prominently among them. www.dcntral.com.

Having taken a deep dive into new variants on the blockchain theme, including Ethereum’s blockchain and IOTA’s “blockless,” Tangle-based means of authenticating, verifying and creating new blocks of transactions, Cohen and Barry are working with Hedera hashgraph specifially using the Hashgraph Consensys algorithms to develop what Cohen dubs “AI 3.0” and build out dcntral.ai’s Cybersecure Transactive Networks platform.

A new, fast and secure means of peer-to-peer network transaction processing

Akin to all blockchain distributed ledger systems, Hedera hashgraph offers a new means of achieving consensus among blockchain transaction system peers. That is to say it provides “a way for people who don’t know or trust each other to securely collaborate and transact online without the need for a trusted intermediary,” Hedera hashgraph’s creators explain.

Unlike blockchains based on Bitcoin’s “proof of work” method of achieving consensus, Hedera hashgraph, according to its creators, “is lightning fast, secure, and fair, and, unlike some blockchain-based platforms, doesn’t require compute-heavy proof-of-work.”

Hedera hashgraph released the results of a transaction processing speed test of its public distributed ledger platform alongside launching the public hashgraph platform. Fifty thousand transactions were processed in three seconds using a peer-to-peer network to which 30 computers spanning eight regions of the world were connected.

Analyzing the results further, that equates to 1.5 seconds across 2,000 miles (3,200 kms) or 0.75 seconds among peers located within a single region.

Byzantine fault tolerance and meta-gossip

Digging a bit deeper into its technical aspects,Hedera hashgraph employs what’s known as Byzantine fault tolerance to ensure that transactions and communications are highly secure and tamper-proof. Consensus time-stamping of prospective and authenticated transactions and blocks is used to ensure fairness.

Equally important, Hedera hashgraph is able to process hundreds of thousands of transactions per seconds. That’s a huge improvement over Bitcoin blockchain transaction processing, in terms of cost per transaction and energy consumption as well as transaction processing speed.

The founders of Swirlds, a permission- and hashgraph-based distributed ledger, launched Hedera hashgraph, a public use version of the platform, on March 13. Swirld’s hashgraph mechanism for achieving blockchain consensus, in turn, was created by Leemon Baird.

Essentially, hashgraph blockchains use a virtual voting algorithm combined with what’s known as the “gossip protocol” to achieve consensus quickly, fairly and efficently, TechCrunch’s Samantha Stein explains in a March 13 news report.

In order to achieve consensus among peers much faster and more efficiently, the gossip protocol makes use of “meta-gossip” — gossip about gossip. Essentially, “gossip about gossip” amounts to information regarding transactions exchanged by hashgraph peers that isn’t known across all network nodes.

The gossip protocol gathers critical information contained in the meta-gossip to do with new transactions, including via which distributed network peer it originated and how far and wide it traveled among peers. The entire history of messages associated with a new, prospective transaction to be added in the creation of a new block are consolidated, in temporal, ordinal sequence, into one hash.

Predicting how network peers will vote

The result is that Hedera hashgraph can predict how network peers will vote when it comes time to authenticate and add a new transaction or block without them actually having to vote. That winds up saving a tremendous amount of time and boosts transaction processing efficiency by orders of magnitude. It also save a tremendous amount of energy.

“I can guess how you would vote, but you don’t need to vote, so you reach consensus for free. It’s the fastest way known to humanity to send information,” Baird was quoted in Stein’s article for TechCrunch…

“We can process hundreds of thousands of transactions per second on Hashgraph Hedera, compared to proof of work blockchains like Bitcoin or Ethereum’s blockchain that can do 5–7 transactions per second,” Stein quoted Swirlds’ co-founder Mance Harmon.

Stein notes that would make Hedera hashgraph’s transaction processing speed faster than that of Visa’s credit and debit card transaction processing.

Of vital importance when it comes to avoiding coming under the hammer of national and international regulators, Hedera Hashgraph platform comes equipped with anti-money laundering and so-called “Know Your Customer” peer identification.

Hedera hashgraph and Dcntral.ai’s AI 3.0

These attributes figured prominently in Cohen and Barry’s decision to make use of Hedera Hashgraph to design and build out dcentral.ai’s “AI 3.0” functionality and the Cybersecure Transactions Network platform. Right now we are planning to use the Hashgraph Consensys algortithms for private permission-based network implementations but we will also consider using the Hedera Hashgraph public ledger in the future said Cohen.

“AI 3.0 combines the benefits of over 30 years of research on AI, machine learning, and multi-agent systems with blockchain and DLT technology to finally enable the emerging industry 4.0 where billions of devices will be connected to the internet and will need to coordinate in real-time at the edge of the network,” Cohen wrote in a Nov. 30, 2017 post for Hedera Hashgraph’s Medium channel.

Cohen dug deep into and assessed alternative, so-called “blockless,” blockchains before deciding to work with Hashgraph among others. Leading examples of these, such as DAGCoin and IOTA, make use of their own versions of what is known as a Directed Acrylic Graph (DAG) to resolve the scalability and processing speed/efficiency issues that constrain blockchains that make use of “proof of work” to achieve peer consensus and create new transactions and blocks.

Cohen found them lacking in features. “While these may have found suitable use cases, in evaluating these technologies, I determined that none would meet all of my requirements (scalability, speed, footprint, fault tolerance, cybersecurity, AI integration, communications, etc for initial use in permissioned networks.”

As Cohen recounts, he was fortunate to meet Baird and Harmon while working to create “the perfect underlying blockchain foundation” for mission-critical cyber-physical systems. With funding from private investor and the U.S. Department of Energy (DOE), Cohen, since joined by Barry, continues along that path of innovation.

Interested in hashgraph and next-gen blockchain distributed computing systems, distributed ledger and cryptocurrency systems and platform development. There’s much more to come on dcntral.ai, as well as here on its Medium channel.

-Miningzoo.com a perfect cloud mining solution just for you!

With the trading war causing all the anxiety leading to stock price plummeting and bitcoin price skyrocketing, large institutions start to pour their funds into bitcoin investment gradually to diversify their investment portfolio.

Even if you do not long Bitcoin or consider it digitized gold, like Tim Draper and other investment gurus do, you might want to buy some bitcoin for diversification, an investment strategy taught in Yale’s Financial Markets class by Nobel laureate, Robert Schiller.

You can always buy bitcoin with cash, but if you hate to withstand its rollercoaster price but want to produce bitcoin yourself, what are the options?

First, you need to buy miners, which are costly. Second, you need to be able to operate the miners. This requires a lot of time, energy and of course know-how in technical set-up and assembling. How and where to set those miners up? And on top of these, various risks like technical failures and electricity blackout.

MiningZoo’s cloud mining is an optimal alternative choice if you find the previous two ways too much trouble.

The advantages of cloud mining compared to buy and run mining machine yourself are obvious: it is noise-free, and…

With the Bitcoin Spot market in a stand-still relative to the price upswings of the past months (surging as high as $9,000), BTC futures market is taking the baton, helping traders profit from the strong upward trend as well as the huge downside movement in past 3 days. The XBT products amassed the least average volume in USD at $644.5 million, and open Interest for the derivative product posted a figure of $212 million.

Ever since the recent bull run began, Wall Street has been trading Bitcoin Future contracts in larger volume and despite BTC now sluggish, the trend continues. According to financial markets analyst Alex Krüger, trade volume of XBT futures contracts soared to unimaginable highs owing to the larger price effect and institutional adoption that buoyed the BTC market. It should be noted that, with the price up and down, Bitcoin futures trading seems to be a favorite at Wall Street. In other words, BTC futures contracts might be the most profitable trading method during the recent market trend.
