When the Internet was first established, it did not consider privacy, especially the complex security features required by today’s standards. It’s too late to redesign the entire Internet, however, two blockchain projects offer potential security solutions. The function of blockchain as a decentralized payment system may be the secret of network security in the future.

Is blockchain suitable for Internet security

At first, the Internet originated from the idea that multiple arbitrarily designed networks could be combined to create a global digital data exchange system. When the technologies that need to influence this idea are designed, no one really thinks that they may end up being used in everything from sensitive communications to business and between. So it’s clear that the basic technologies that make up today’s Internet have few built-in security features.

The initial negligence caused a lot of trouble. E-mail system suffers from spam, because no one thought of establishing sender authenticity check in the transmission protocol. Because the public Internet has no built-in encryption system, private communication is often blocked. Websites and services are facing an increasingly serious threat from DDoS attacks, which seems to be more and more serious year by year.

In response, most users have turned to a variety of solutions to solve a large number of security problems caused by the use of the Internet. They use spam filters to protect their inboxes. They will pay extra to use VPN for torrent and other privacy sensitive online activities. Web operators now rely on companies like cloudflare and Imperva to protect them from all kinds of attacks.

Obviously, from the perspective of security, we need to conduct a comprehensive reflection on the operation of the Internet. Now, many people who study this issue believe that a recent technology, blockchain, may be the solution to today’s Internet problems. Here are two projects designed to use them for specific purposes.

Data hosting, distributed

The first project aims to build a more secure and decentralized Internet using blockchain, which is called interplanetary file system (IPFs). The basic idea is to use blockchain to manage the storage of Internet data and spread it to the connected nodes (Internet users), so that the data not only has the ability of anti censorship, but also has the ability of anti attack.

In practical application, the system tries to replace the centralized online data storage and the classic server client architecture of traditional Internet. In theory, it works very simply. Its function is like a P2P network (such as BitTorrent), where each new requester of a file becomes another host. This data will be represented as an encrypted hash on the blockchain and connected to the naming structure with a built-in DNS replacement called IPNs.

In order to maintain the normal operation of the whole network, nodes use an encryption currency named filecoin to pay for their storage and bandwidth costs. This provides the necessary incentive to ensure that all uploaded files are always available. With the development of the network, it may lead to faster file retrieval than today’s Internet, and will make the website using it immune to DDoS attacks or code injection attacks.

Blockchain privacy network

Anyone proficient in Internet privacy knows that when you need a secure and unregulated network connection, you have two main choices: VPN or tor. However, for many people, the idea of paying for VPN services on the basis of existing Internet services is not desirable. Although tor network is free for anyone, it is not suitable for ordinary Internet users due to performance problems.

That’s when orchid comes in handy. This is a block chain project designed to be a missing link, combining the essence of VPN technology with the network advantages such as Tor. In short, the Archid privacy network allows traditional VPN providers to sell their excess bandwidth to users by becoming part of a decentralized P2P privacy network.

The public network and end-user application, launched on December 19, includes five initial bandwidth partners. Users can access the privacy network using a pay as you go account, which is funded by orchard’s native token OXT. Bandwidth providers also have to keep deposits in OXT currency to participate, which helps ensure that users’ privacy is maintained through a self-regulated penalty system. When running on a large scale, the resulting system should be cheaper for end users, more beneficial for providers, and not subject to external monitoring – in short, it could become an anonymous global data obfuscation layer for the entire Internet.

Secure Internet

Although it’s much more effective to redesign the Internet and its systems from scratch to make them more anonymous and secure, we’ve long passed this stage. At the same time, additional security solutions also face a steep adoption curve. Even Google, which has a lot of resources, has failed to achieve 100% SSL encryption on its products despite years of efforts.

However, the two blockchain products mentioned above have something that previous network security solutions did not have: financial incentive system. Finally, the ability of blockchain as a decentralized payment system may be the secret of creating the next generation of Internet that people are willing to use, and the early adopters of blockchain may be rewarded for their role, making the Internet a safer place once and for all.
