The Game of Life: Visualizing China’s Social Credit System

In an attempt to imbue trust, China has announced a plan to implement a national ranking system for its citizens and companies. Currently in pilot mode, the new system will be rolled out in 2020, and go through numerous iterations before becoming official.

While the system may be a useful tool for China to manage its growing 1.4 billion population, it has triggered global concerns around the ethics of big data, and whether the system is a breach of fundamental human rights.

Today’s infographic looks at how China’s proposed social credit system could work, and what the implications might be.

The Government is Always Watching

Currently, the pilot system varies from place to place, whereas the new system is envisioned as a unified system. Although the pilot program may be more of an experiment than a precursor, it gives a good indication of what to expect.

In the pilot system, each citizen is assigned 1,000 points and is consistently monitored and rated on how they behave. Points are earned through good deeds, and lost for bad behavior. Users increase points by donating blood or money, praising the government on social media, and helping the poor. Rewards for such behavior can range from getting a promotion at work fast-tracked, to receiving priority status for children’s school admissions.

In contrast, not visiting one’s aging parents regularly, spreading rumors on the internet, and cheating in online games are considered antisocial behaviors. Punishments include public shaming, exclusion from booking flights or train tickets, and restricted access to public services.

Big Data Goes Right to the Source

The perpetual surveillance that comes with the new system is expected to draw on huge amounts of data from a variety of traditional and digital sources.

Police officers have used AI-powered smart glasses and drones to effectively monitor citizens. Footage from these devices showing antisocial behavior can be broadcast to the public to shame the offenders, and deter others from behaving similarly.

For more serious offenders, some cities in China force people to repay debts by switching the person’s ringtone without their permission. The ringtone begins with the sound of a police siren, followed by a message such as:

“The person you are calling has been listed as a discredited person by the local court. Please urge this person to fulfill his or her legal obligations.”

Two of the largest companies in China, Tencent and Alibaba, were enlisted by the People’s Bank of China to play an important role in the credit system, raising the issue of third-party data security. WeChat—China’s largest social media platform, owned by Tencent—tracked behavior and ranked users accordingly, while displaying their location in real-time.

Following data concerns, these tech companies—and six others—were not awarded any licenses by the government. However, social media giants are still involved in orchestrating the public shaming of citizens who misbehave.

The Digital Dang’an

The social credit system may not be an entirely new initiative in China. The dang’an (English: record) is a paper file containing an individual’s school reports, information on physical characteristics, employment records, and photographs.

These dossiers, which were first used in the Maoist years, helped the government in maintaining control of its citizens. This gathering of citizen’s data for China’s social credit system may in fact be seen as a revival of the principle of dang’an in the digital era, with the system providing a powerful tool to monitor citizens whose data is more difficult to capture.

Is the System Working?

In 2018, people with a low score were prohibited from buying plane tickets almost 18 million times, while high-speed train ticket transactions were blocked 5.5 million times. A further 128 people were prohibited from leaving China, due to unpaid taxes.

The system could have major implications for foreign business practices—as preference could be given to companies already ranked in the system. Companies with higher scores will be rewarded with incentives which include lower tax rates and better credit conditions, with their behavior being judged in areas such as:

Paid taxes
Customs regulation
Environmental protection

Despite the complexities of gathering vast amounts of data, the system is certainly making an impact. While there are benefits to having a standardized scoring system, and encouraging positive behavior—will it be worth the social cost of gamifying human life?

Radiation Emissions of Popular Smartphones

Smartphones have become an integral part of our everyday lives. From work and school to daily tasks, these handheld devices have brought everything into the palm of our hands.

Most people spend 5-6 hours on their phones each day. And, given that our phones emit a tiny amount of radiation, we’re exposing ourselves to radiation for hours each day.

But different phones emit different amounts of radiation.

With the help of data collected by the German Federal Office of Radiation Protection, we visualize the radiation emissions of some popular smartphones in the market today.

Radiation and SAR Values of Smartphones

Smartphones and other mobile devices emit tiny amounts of radiofrequency (RF) radiation. Humans can absorb this radiation when the smartphone is being used or is lying dormant anywhere near their bodies.

The parameter used to measure phone radiation emissions is the Specific Absorption Rate (SAR). It is the unit of measurement that represents the quantity of electromagnetic energy absorbed by the body when using a mobile device.

The Council of the European Union has set radiation standards for cell phones at 2 watts per kilogram, measured over the 10 grams of tissue that is absorbing the most signal.

SAR values are calculated at the ear (speaking on the phone) and at the body (kept in your pocket). For the purposes of this article, we’ve used the former calculations.

Smartphones With the Highest Levels of Radiation Emissions

The Motorola Edge has the highest radiation emission with a SAR value of 1.79 watts of radiation per kilogram. That’s significantly higher than most other smartphone models in the market today and close to the limits set by the EU for cellphones.

Coming in second is the Axon 11 5G by ZTE with 1.59, followed by the OnePlus 6T at a close third with 1.55 W/kg. The Sony Experia AX2 Plus with 1.41 and the Google Pixel 3 XL and 3A XL at 1.39 round out the top five.

Here is a look at the 10 smartphones that emit the highest level of radiation:

Smartphones with the lowest level of radiation

Now that we have detailed the worst offenders let’s look at the smartphones with the lowest levels of radiation emissions.

Smartphones With the Lowest Levels of Radiation Emissions

The smartphone with the lowest SAR value is the ZTE Blade V10, with 0.13 watts of radiation per kilogram.

Mobile devices by Samsung carry some of the least radiation risks. The company has four phones considered to be the best in the category. The Galaxy Note 10+ is the best model in their line-up, emitting a meager 0.19 watts per kilogram.

Here is a look at the 10 smartphones that emit the lowest levels of radiation:

Smartphones with the highest level of radiation

There is currently no significant research proving the harmful effects of phone radiation.

Despite this, people who are in contact with their devices for extended periods can at least quantify their radiation exposure and make choices about which brands serve their needs.

How the Top Cryptocurrencies Performed in 2021

Cryptocurrencies had a breakout year in 2021, providing plenty of volatility and strong returns across crypto’s various sectors.

The Returns of Top Cryptocurrencies in 2021

2021 saw the crypto markets boom and mature, with different sectors flourishing and largely outperforming the market leader, bitcoin.

While bitcoin only managed to return 59.8% last year, the crypto sector’s total market cap grew by 187.5%, with many of the top coins offering four and even five-digit percentage returns.

2021 Crypto Market Roundup

Last year wasn’t just a breakout year for crypto in terms of returns, but also the growing infrastructure’s maturity and resulting decorrelation of individual crypto industries and coins.

Crypto’s infrastructure has developed significantly, and there are now many more onramps for people to buy altcoins that don’t require purchasing and using bitcoin in the process. As a result, many cryptocurrency prices were more dictated by the value and functionality of their protocol and applications rather than their correlation to bitcoin.

Cryptocurrency	Category	2021 Returns
Bitcoin	Cryptocurrency	59.8%
Ethereum	Smart Contract Platform	399.2%
Binance Coin	Exchange Token	1,268.9%
Solana	Smart Contract Platform	11,177.8%
Cardano	Smart Contract Platform	621.3%
XRP	Cryptocurrency	277.8%
Terra	Smart Contract Platform	12,967.3%
Avalanche	Smart Contract Platform	3,334.8%
Polkadot	Smart Contract Platform	187.9%
Dogecoin	Meme Coin	3,546.0%

Bitcoin wasn’t the only cryptocurrency that didn’t manage to reach triple-digit returns in 2021. Litecoin and Bitcoin Cash also provided meagre double-digit percentage returns, as payment-focused cryptocurrencies were largely ignored for projects with smart contract capabilities.

Other older projects like Stellar Lumens (109%) and XRP (278%) provided triple-digit returns, with Cardano (621%) being the best performer of the old guard despite not managing to ship its smart contract functionality last year.

The Rise of the Ethereum Competitors

Ethereum greatly outpaced bitcoin in 2021, returning 399.2% as the popularity boom of NFTs and creation of DeFi 2.0 protocols like Olympus (OHM) expanded possible use-cases.

But with the rise of network activity, a 50% increase in transfers in 2021, Ethereum gas fees surged. From minimums of $20 for a single transaction, to NFT mint prices starting around $40 and going into the hundreds on congested network days, crypto’s retail crowd migrated to other smart contract platforms with lower fees.

Alternative budding smart contract platforms like Solana (11,178%), Avalanche (3,335%), and Fantom (13,207%) all had 4-5 digit percentage returns, as these protocols built out their own decentralized finance ecosystems and NFT markets.

With Ethereum set to merge onto the beacon chain this year, which uses proof of stake instead of proof of work, we’ll see if 2022 brings lower gas fees and retail’s return to Ethereum if the merge is successful.

Dog Coins Meme their Way to the Top

While many new cryptocurrencies with strong functionality and unique use-cases were rewarded with strong returns, it was memes that powered the greatest returns in cryptocurrencies this past year.

Dogecoin’s surge after Elon Musk’s “adoption” saw many other dog coins follow, with SHIB benefitting the most and returning an astounding 19.85 million percent.

But ever since Dogecoin’s run from $0.07 to a high of $0.74 in Q2 of last year, the original meme coin’s price has slowly bled -77% down to $0.17 at the time of writing. After the roller coaster ride of last year, 2022 started with a positive catalyst for Dogecoin holders as Elon Musk announced DOGE can be used to purchase Tesla merchandise.

Gamifying the Crypto Industry

The intersection between crypto, games, and the metaverse became more than just a pipe dream in 2021. Axie Infinity was the first crypto native game to successfully establish a play to earn structure that combines its native token (AXS) and in-game NFTs, becoming a sensation and source of income for many in the Philippines.

Other crypto gaming projects like Defi Kingdoms are putting recognizable game interfaces on decentralized finance applications, with the decentralized exchange becoming the town’s “marketplace” and yield farms being the “gardens” where yield is harvested. This fantasy aesthetic is more than just a new coat of paint, as the project with $1.04B of total value locked is developing an underlying play-to-earn game.

Along with gamification, 2021 saw crypto native and non-crypto developers put a big emphasis on the digital worlds or metaverses users will inhabit. Facebook’s name change to Meta resulted in the two prominent metaverse projects The Sandbox (SAND) and Decentraland (MANA) surge another few hundred percent to finish off the year at 16,261% and 4,104% returns respectively.

With so many eyes on the crypto sector after the 2021’s breakout year, we’ll see how developing U.S. regulation and changing macro conditions affect cryptocurrencies in 2022.
