The Dash 4 Cash is a series of races in the NASCAR Xfinity Series. Since its inception in 2009, the program has undergone many changes, most notably the addition of heat races in 2016. 2009–10: Inception. In order to drum up interest in its second-tier series, NASCAR made the Dash 4 Cash before the 2009 season. Dash 6.0.2 macOS. Dash is an API Documentation Browser and Code Snippet Manager. Dash helps you store snippets of code, as well as instantly search and browse documentation for almost any API you might use (for a full list, see below).

Dash is an open sourcecryptocurrency. It is an altcoin that was forked from the Bitcoin protocol. It is also a decentralized autonomous organization (DAO) run by a subset of its users, which are called 'masternodes'.

History[edit]

The currency was launched in January 2014 as 'Xcoin' by Evan Duffield, as a fork of the Bitcoin protocol.^[2][3] It is an altcoin and in its early days it was subject to pump and dump speculation.^[4] It was rebranded as Darkcoin,^[5] which received press for being used in dark net markets.^[6] In March 2015, it rebranded again with the name Dash as a portmanteau of 'digital cash'.^[4] As of August 2016, Dash is no longer used in any major dark net markets worth noting.^[5]

In early 2017 Duffield, who lived in the Phoenix area, and some other people working on Dash took space in a business incubator at Arizona State University.^[7] The Dash DAO later funded a blockchain research lab at ASU.^[8]

As of April 2018, Dash's market capitalization was around $4.3 billion and it was one of the top 12 cryptocurrencies.^[9]

As of February 2019, Dash was the most popular cryptocurrency in Venezuela according to Der Spiegel.^[10]

Design and governance[edit]

Dash was designed to allow transactions quickly and to have a swift governance structure in order to overcome shortfalls in Bitcoin.^[4]

Governance[edit]

Governance is handled through a form of decentralized autonomous organization in which decisions are made on a blockchain via masternodes. Masternodes perform standard node functions like hosting a copy of the blockchain, relaying messages, and validating transactions on the network, and in addition act as shareholders, voting on proposals for improving Dash's ecosystem. Along with masternodes, the system includes standard nodes and miners.^[2][11][12]

Running a masternode requires ownership of 1000 Dash. Masternodes are also required to have a static IP address and meet minimum requirements for CPU, RAM, disk space and network bandwidth.^[11]

A proof of service protocol ensures that masternodes have the most current blockchain protocol and are online.^[11]

The system's decentralization has been criticized due to a mishap, which allowed too many coins to be distributed at release. This concentrated the wealth to a small group, giving them disproportionate power in decisions over the currency's future.^[9]

Consensus[edit]

As of 2018 coins were mined using a proof of work algorithm with a hash function called 'X11', with eleven rounds of hashing, and the average time to mine a coin was around two and a half minutes.^[2]

Transactions[edit]

Masternodes provide two additional kinds of transactions. 'InstantSend' bypasses mining and instead requires a consensus of masternodes to validate a transaction, speeding transactions.^[4][2] 'PrivateSend' is intended to give users optional consumer-grade privacy; it mixes participating users' unspent Dash before executing a transaction.^[2][11]

Dash-funded organizations[edit]

The Dash DAO uses the 10% it receives from mining to invest as the DAO chooses, using a decentralised voting system.^[11] This has allowed the creation of many funded organizations, including Dash Core Group, Inc. (DCG), which supports continued development, integrations, and other activities of Dash.^[1]

Are you sure that dash cam is really 4K?

If you do a search on Amazon for '4K dash cam' you will get hundreds of results, showing you a long list of dash cams that claim to be 4K, but in actuality they are not. In order for a dash camera to record real 4K video (3840x2160p), they need to have at least an 8MP image sensor. Most of them only have 2MP or 4MP image sensors. They claim to be 4K because the video is resized into what appears to be a 4K video file, although it was not actually recorded at 3840 x 2160p.

There are currently only a handful of real 4K dash cams being sold today.

Our Reviews of the Top 6 Best REAL 4K Dash Cams

#6 Lifechaser Dual Dash Cam 4K

The LifeChaser 4K front car camera records real 4K videos in 3840 x 2160P @ 30fps, using the Hisilicon HI3559V200 Processor and the 8MP OmniVision OS08A10 image sensor. It uses a 170 degree lens angle, which is one of the widest used on a 4K dash cam. A wider angle lens can provide more coverage of the road, but can cause some distortion at times, although you should still be able to pick up license plate numbers among other things.

This dash cam comes with all the standard features you will find on most mid range cameras, like parking mode (requires separate hardwire kit), motion detection and a g-sensor to detect impacts so it can save and lock video files in the event of a crash.

Inside the dash cam is a GPS feature that can display your speed and coordinates on the video, along with built-in WiFi to connect to the dash cam with your smartphone or tablet.

On the back of the dash cam it has a 2.4″ IPS screen and buttons below to change settings and view saved videos.

LifeChaser does not have much of an online presence. If you do a basic Google search for 'LifeChaser' you will not find a company website with customer service options or product user manuals or firmware updates.

PROS

• Built-in WiFi and GPS
• Dual Dash Cam Package, low priced 4K dash cam that also includes a rear camera
• No company watermark on video files

CONS

• Uses a 250mAh lithium ion battery instead of a capacitor, which can lead to overheating and reliability issues
• Only supports up to a 128gb microSD card, while others support up to 256gb
• Not an established brand. Limited online presence which can lead to poor customer support and little to no future firmware updates

Lifechaser 4K Dash Cam Specs

• 4K Video on Front Cam
• 1080p HD Rear Cam
• OmniVision OS08A10 Image Sensor
• 170° lens angle

• Parking mode features

#5 Vantrue X4 UHD 4K

The X4 from Vantrue claims to be the Worlds first 4K 160° dash cam. Although it may not be the worlds first 4K dash cam, it might be the worlds first 4K car camera with a wide 160 degree lens angle. This is the widest lens angle currently being sold on the market today for 4K dash cams, giving you more coverage of the road in front of you.

Using the 8MP IMX317 image sensor from Sony, ensures a crisp video quality over the other generic and off brand image sensors used in other dash cams. Because it uses a 8MP image sensor, you know it records real 4K video and the X4 supports up to a 256gb microSD memory card (Vantrue recommends the Samsung Pro Endurance card), giving you more than 12 hours of video storage. When the memory card fills up it will loop back and record over the oldest video files automatically.

It has a rear 3.0 inch TFT LCD display screen, allowing you to make camera setting changes or view video footage directly on the unit itself, rather than having to use a USB cable or remotely connect to it through your smartphone.

The X4 has a built-in parking mode feature which can protect your car when parked, offering motion and impact detection, which records when either is recorded. This feature requires a hardwire kit that plugs into your cars fuse box, which is sold separately.

PROS

• Has a capacitor rather than battery, better for high heat and reliability
• Wide 160° lens angle
• Uses Wide Dynamic Range (WDR) to get better low light video

CONS

• Uses a suction cup mount, which can often fall off and hangs down low, making it less stealthy and prone to theft because it's more visible.
• Does not come with built-in GPS, you need to purchase a separate GPS module that plugs into the mount.

Vantrue X4 Dash Cam Specs

With it's camera feature, it takes 20MP still photos. Within the firmware, the Stealth 4K uses an algorithm to correct image distortion, to help with the curvature of the photo from the wide angle lens and output a clearer image.

As with most mid to top end dash cams these days, the Stealth 4K comes with a 24/7 parking mode feature that can detect motion and impact with its g-sensor while your car is parked and you're away. This does require a separate hardwire kit that plugs into your cars fuse box, so it can power itself when your car is turned off.

New version called the ROVE Stealth 4K PRO will be for sale soon.

Unlike some other dash cams that offer GPS, where you are required to purchase a separate addon GPS module that can take up more space on your cars windshield, the Stealth 4K comes with GPS built inside the unit. The GPS feature can be used to display your speed and coordinates directly on to the saved video file.

ROVE has a customer care center based in Chicago and is known for their good customer support, providing customers with the chance to get a full refund within 30 days if they're not happy with the camera.

The A129 Pro Duo offers two different options for its rear camera. You can either go with the common rear camera that is meant to be mounted on your back window and recording outside, or an interior infrared camera that mounts facing inwards and records the interior of your car, often used by Uber, Lyft or taxi drivers.

#1 Blackvue DR900S-2CH 4K

The DR900S, our number 1 pick for the best 4k dash cam in 2020.

Blackvue is known in the dash cam community as the top of the line brand of car cameras. When people ask online about what the 'best dash cam' is, people will often point them towards a Blackvue dash cam.

While many brands have come out with flashy colors and fancy looking cameras, Blackvue has stuck with their discrete, all black tube shaped design, giving car owners a stealthy and somewhat hidden dash cam.

Blackvues DR900S-2CH has a 162 degree lens angle on the front camera, recording in real 4K (3840x2160p @ 30fps) using an 8MP image sensor, while the rear camera has a 139 degree lens angle and records full HD (1920x1080p @ 30fps) using a 2MP Sony STARVISTM CMOS image sensor.

The parking mode feature will keep the dash cam in standby, waiting for an impact to be detected or the motion of someone walking up to your car. This will trigger the camera to begin recording and capture an event while you are away from your car. To use this feature, you will need to buy an optional hardwire kit or their external battery, the Power Magic Battery Pack.

Because of its small size, the DR900S does not have an LCD screen on it, so to view videos or change the dash cam settings you need to use the Blackvue APP on your Android or iOS smartphone or tablet.

For an added fee, there is the Blackvue Cloud service, which offers remote viewing of video and push notifications to your phone in the event of a crash. You may also remotely backup important video files to the cloud.

PROS

• Uses capacitor rather than a battery, which is better for high heat
• Stealth design
• Trusted brand with good customer service and support

BlackVue DR900S Dash Cam Specs

• Real 4K Video (3840×2160 @ 30FPS)
• 8MP Image Sensor
• 162° Lens Angle
• 256GB microSD Capacity

• WiFi, built-in
• GPS, built-in

List of Fake 4K Dash Cams

Here are some of the more popular dash cams that are marketing themselves as 4K on sites like Amazon, Best Buy and Walmart.

FYI – You need an 8MP image sensor to record real 4K, 3840 x 2160 pixels or 4096 x 2160 pixels.

AUKEY 4K Dash Cam

The AUKEY DR02 J dash cam claims to be 4K and having a resolution of 2880 x 2160. While this might be true for the final video file that is saved, the camera is not capturing video in true 4K. With its 5.1MP AR0521 image sensor and without resizing after the video, the camera would normal capture video at 1440p, while true 4K is 3840p. While the AUKEY DR02 J does have good video quality and comes at a cheap price, it is not real 4K.

Rove R2-4K Dash Cam

While the Rove R2 has some nice features like built-in WiFi and built-in GPS to track your cars location on Google Maps and your current speed. While this dash cam from Rove claims '4K ULTRA HD RECORDING', it does not record in real native 4K. It uses the OmniVision OV4689 4-megapixel image sensor, which does not record in actual 4K resolution.

Rexing V1 3rd Generation 4K Dash Cam

Like many of the other fake 4K dashcams, Rexing makes it hard to find what image sensor they use in this camera. Only after emailing customer support were we able to find out that it uses 'The OV4689 is a high performance 4-megapixel CameraChip™ sensor in a native 16:9 format'. The V1 3rd Gen is recroding at 1080p and increasing the video to a 4K resolution.

AZDOME M06 4K Ultra HD Dash Cam

The M06 dash cam from AZDOME that claims to be 4K uses a OV4689 4-megapixel CameraChip™ sensor from OmniVision. This sensor is not capable of 4K video. AZDOME is interpolating or upscaling the video into what appears to be a 2880 x 2160p 4K resolution video file.

AZDOME GS63H 4K Dash Cam

The GS63H from AZDOME comes with many features like built-in WiFi, GPS and its own smartphone APP, it does not come with true 4K video recording.

Dash 4 6 3 Beta 2

On the Amazon listing page it claims to have a '6-megapixel OV4689 pro 1/3inch CMOS sensor', while on its official website page for the GS63H is says it has a 'OV4689 Sensor, 4.0 Megapixels, Max 4k Resolution, 2880*2160p/24fps'. Even though the 2 differ from each other, both image sensors are not big enough to record real 4K dash cam video.

TOGUARD 4k Dash Cam

Dash 4 6 3 X 2

The first thing you'll notice about this dash cam that is odd is that it only takes a 32GB microSD card. This is on the low end, something you don't see in any modern dash cam, especially not a 4K, not even a 1080p camera. We're still waiting to hear an officially response from TOGUARD on what image sensor they use, but we're almost certain this is a fake 4k dash cam.
