Both Bitcoin as well as Bitcoin Cash use a proof-of-work algorithm to timestamp every new block. The proof of work algorithm used is the same in both cases. It can be described as a partial inversion of a hash function. Additionally, both Bitcoin and Bitcoin Cash target a new block to be generated every ten minutes on average. The time needed to calculate a new block is influenced by a parameter called the mining difficulty. If the total amount of mining power increases, an increase of the mining difficulty can keep the block time roughly constant. Vice versa, if the mining power decreases, a decrease of the mining difficulty can keep the block time roughly constant.[36]

The current version, Exchange Server 2019,[2] was released in October 2018.

One of the key features of the new release is that Exchange Server can be deployed onto Windows Server Core for the first time, additionally Microsoft has retired the Unified Messaging feature of Exchange, meaning that Skype for Business on-premises customers will have to use alternative solutions for voicemail, such as Azure cloud voicemail. Unified Messaging continues to exist in Exchange Online requiring an Exchange Plan 2 license.

Exchange Server Enterprise Edition supports clustering of up to 4 nodes when using Windows 2000 Server, and up to 8 nodes with Windows Server 2003. Exchange Server 2003 also introduced active-active clustering, but for two-node clusters only. In this setup, both servers in the cluster are allowed to be active simultaneously. This is opposed to Exchange's more common active-passive mode in which the failover servers in any cluster node cannot be used at all while their corresponding home servers are active. They must wait, inactive, for the home servers in the node to fail. Subsequent performance issues with active-active mode have led Microsoft to recommend that it should no longer be used.[3] In fact, support for active-active mode clustering has been discontinued with Exchange Server 2007.

Crypto (2019) is fairly standard DTV fare. The script tosses around a lot of buzz words about crypto currencies and money laundering. The plot involves money laundering, Russian mobsters, multi-million-dollar paintings that look as if they could have been mass-produced in a factory in Mexico alongside the paintings on velvet, murder, extortion, embezzlement, the dark web, kidnapping, and other nefarious activities, none of which makes much sense. The script offers a few clever lines of dialogue and a lot of well-worn tropes. Performances are often a bit wooden, but the camera is generally rock steady.

To keep the block generation time equal to ten minutes on average, both Bitcoin and Bitcoin Cash use an algorithm adjusting the mining difficulty parameter. This algorithm is called the difficulty adjustment algorithm (DAA). Originally, both Bitcoin and Bitcoin Cash used the same difficulty adjustment algorithm, adjusting the mining difficulty parameter every 2016 blocks. Since 1 August 2017, Bitcoin Cash also used an addition to the DAA, called an Emergency Difficulty Adjustment (EDA) algorithm. EDA was used alongside the original DAA and it was designed to decrease the mining difficulty of Bitcoin Cash by 20%, if the time difference between 6 successive blocks was greater than 12 hours.[36]

Several scenes involving harvesting potatoes don't seem at all realistic, even to a city boy like myself. In one scene, Martin Senior (Kurt Russell) harrows a field which supposedly hasn't been harvested. He has a nice John Deere tractor, but can't afford even a simple potato harvester for a farm worth over a million dollars, which means it is probably over 400 acres. The potato stalks are missing. How they removed the stalks without harvesting the potatoes is the biggest mystery in the film. But three guys manage to harvest 400 acres of potatoes in an afternoon. The potatoes have no dirt clinging to them when they are harvested. It really looks as if somebody took a couple of sacks of potatoes and covered them with a little dirt in a freshly ploughed field. If harvesting potatoes is a significant plot element, producers really need to schedule production in the fall, rather than the spring.

While exchanges commonly refer to BTC as simply “Bitcoin”, Bitcoin Cash, usually represented by the BCH ticker symbol, is considered by its supporters to be a legitimate continuation of the Bitcoin project, and the version with the best chance of creating a globally adopted peer-to-peer electronic cash system.

With Exchange Server 2010, Microsoft introduced the concept of the Database Availability Group (DAG). A DAG contains Mailbox servers that become members of the DAG. Once a Mailbox server is a member of a DAG, the Mailbox Databases on that server can be copied to other members of the DAG. When a Mailbox server is added to a DAG, the Failover Clustering Windows role is installed on the server and all required clustering resources are created.
