Blockchain technologies are spreading outside PCs. Each year devices start to support the blockchain and cryptocurrencies. Let’s take a look at some more (or less) successful examples.
As we know China is one of the first countries that started to work on the Central Bank Digital Currency (CBDC). Now Huawei is ready to launch a new smartphone with a built-in hardware wallet. This smartphone will have several features:
- support of the dual offline payments
- controllable and anonymous authentication
- security of a hardware-level
Recently the Chinese government has been testing the digital yuan. More and more people join the program. According to statistics, about 40% of Chinese citizens are using Huawei smartphones. That makes Huawei the most massive producer of smartphones in China. The built-in wallet will make it easier for people to use new digital currency and thus the adoption will be easier.
Huawei is not the first one to create a smartphone that supports digital currency. The first smartphones with this feature appeared back in 2018. HTC played a pioneering role in this. This company developed a smartphone that supported blockchain technology. It allowed users to store crypto and could be a part of the blockchain network as a computer node.
The next was the Swiss company Sirin Labs. This company’s smartphone had built-in cold storage for cryptocurrencies and tokens.
Samsung also has interesting decisions. Galaxy S10 has an application to store private keys and a built-in crypto wallet, which supports more than 30 cryptocurrencies. “KlaytnPhone”, a variation of Galaxy Note 10 got a built-in crypto wallet, and users received 2000 KLAY tokens, Klaytn blockchain tokens. All these features came together in the Galaxy S20.
So far smartwatches cannot be used to access your crypto wallet, but they have some interesting features. For example, a lot of models can display a current price of crypto, some even have notifications to alert you if the price is crossing some line. Wear OS (Android Wear) also allows users to display a QR code of their crypto wallet.
Even though computers and smartphones are the most logical devices to use blockchain technology, there are lots of other projects. In 2019 Bosch and Wien Energie had a plan to produce a blockchain-based fridge. This feature should help users to control power usage. This fridge was supposed to be controlled by the other smart device. Blockchain technology should also allow users to participate in the energy market using smart contracts. Unfortunately, a release date has not been announced yet.
The fridge is just a part of a smart home. The smart home is a network of connected devices that are making people’s daily lives easier. The existing technologies are vulnerable to outside threats. One of the ideas to make smart homes more secure is to implement blockchain technologies.
The Indian Institute of Information Technology manages water supplies with the help of blockchain and the Internet of Things. So-called smart tanks help to avoid overflowing of tanks in homes by turning it off automatically. This example shows that the implementation of blockchain technology can be used to add more safety for the remote control of different systems.
A Danish company BiChip produced a microchip that can be implanted straight into people’s hands. This microchip can hold the following information: passport, driving license, and medical data. It can also be used as a payment system and store information about the crypto wallet.
The blockchain area and the Crypto World are full of surprises. Probably, in the near future, we will see more technical decisions associated with them. We hope that this article was interesting and useful. Thank you for your attention!
