Is the blockchain mobile phone running Bitcoin full node reliable?

Mobile phone maker HTC wants its smartphone users to access the Bitcoin blockchain.

At a conference last weekend, HTC's Phil Chen announced a new blockchain phone EXODUS 1s, which revealed that the device can be used as a full node of a bitcoin network, which means customers can be on their own devices. Stores data for the entire blockchain.


The company will also provide a software development kit (SDK) for its Zion Vault (HTC's cryptocurrency wallet app) and eventually plan to open source its social key recovery mechanism code.

Phil Chen, HTC's chief decentralized chief officer, said the company's goal is to release products at the end of the third quarter.

He said: "(1s) will be much cheaper and will be easier to buy." The device retails between $250 and $300.

The specifications for this device have not been released.

Running a full-node phone

The most compelling feature of 1s is the ability to run Bitcoin nodes. Chen explained that the company believes this is a very important part of the Bitcoin ecosystem.

We think this is the basis of the entire decentralized network. If you don't hold the key, you don't count Bitcoin or cryptocurrency.

Chen said that EXODUS 1 (HTC's first blockchain phone) was originally designed to allow users to maintain their private keys, which also laid the foundation for the next move.

He believes that from a technical point of view, today's smartphones are physically capable of handling these tasks. He pointed out that the cost of computing chips and storage media is getting lower and lower, and the efficiency is getting higher and higher.

We hope that the functionality of the phone will become powerful enough.

The Bitcoin blockchain (size) is approximately 200 GB and is growing at a rate of 60 GB per year. These numbers are reasonable for smartphones. The iPod has a capacity of 256 GB… Of course, music enthusiasts want to keep the entire music library, and cryptocurrency enthusiasts want to keep the entire bitcoin blockchain.

He said that by letting users run the entire node, HTC helped them achieve autonomous data validation.

(You can) contribute to the security of the entire network and become part of the Bitcoin revolution.

In addition, EXODUS 1s can still perform normal smartphone operations, with music, video, images, apps and Dapps.

Public chain>private chain, bitcoin>other chain

HTC plans to support the Bitcoin blockchain, but does not rule out the possibility of adding support to other networks. He explained that the main considerations include how much memory and bandwidth other networks require.

I think running a light node (such as Ethereum) is completely feasible, but it all depends on the specific parameter specification.

The company also plans to focus on the public blockchain, and Chen believes that it is much easier to support the public chain than the private chain network. Despite this, HTC does not currently intend to explicitly increase support for other networks.

I think Bitcoin is one of the most important blockchains, even if it is not the most important blockchain. Given the openness, neutrality and resistance of its representatives, we definitely want to support this network first.

He also pointed out that Bitcoin is the "most mature" network, and supporting the network is also a little symbolic.

Once HTC launched 1s, Chen hopes his team will be able to bring the experience of supporting Bitcoin nodes to other networks.

Will blockchain mobile phones be the norm in the future? What do you think?
