Best practices in the development of Smart Contracts

Smart contracts are one of the key tools when developing decentralized applications. The problem is that once implemented and deployed on the blockchain, they are immutable and cannot be changed or corrected. That is why there is a base of vulnerabilities to be taken into account during their development and testing, as well as good practices.

Digital twins and Blockchain to enhance the IoT experience

The IoT is a well-known concept globally and is increasingly on the rise as we have discussed in other articles. However, not everyone is familiar with the concept of digital twins. A digital twin is the digital space where all data streams acquired from IoT devices are gathered. Emerging technologies such as Blockchain and AI are critical to usher in the next industrial revolution. Digital twin industry revenues are expected to reach $13.3 billion by 2023.

Understanding ADOS (AirTrace Decentralized Oracle System) and the need for oracles

The main problem with a blockchain is that it cannot communicate directly with the real world. By means of decentralised oracles (DON) and hybrid Smart Contracts where Blockchain-Oracle communicates, real world data is obtained. Airtrace offers the use of a decentralised oracle system combined with artificial intelligence called ADOS (Airtrace Decentralized Oracle System) thus providing a Data Quality Factor (DQF).

IoT device security through NFTs

Non-fungible tokens (NFTs) have been widely used lately for digital art representation. However, the use of NFTs to represent an IoT device is also being studied. There are several solutions for the implementation of this technology in the IoT sector, but in this article you will see the use of PUFs together with NFT's.

The combination of 5G, IoT and Blockchain will be ubiquitous.

The IoT sector has been partially held back mainly by different bottlenecks: data storage capacity, latency reduction and security. However, the combination of solutions such as AI, Blockchain and 5G solve the bottlenecks, enabling massive data processing, in a fast way, and in a secure way.

The new Web 3.0 paradigm will be useful, but not yet.

Web3, 'Spatial Web' or 'New Internet', as they are making it known, will be a major paradigm shift, but it is currently in the adaptation and adoption phase. There is no doubt that Blockchain, AI, IoT, Big Data and Web3 are going to be the technologies that dominate our digital future and it is important to prepare.

AI and Blockchain will accelerate the adoption of the secure Internet of Things (IoST)

The combination of the Internet of Things, Blockchain technology and Artificial Intelligence will drive the adoption of IoST (Internet of Secure Things). Disruptive technologies such as Blockchain or Artificial Intelligence will take the fourth industrial revolution to the next level.

Knowledge Graph, Web3 and Blockchain

One of the best known ways to organize structured knowledge data over the Internet on the web2, is what is known as 'Knowledge Graph'. The move to the web3 requires that a network of graphs is not centralized by entities. This is why technologies such as blockchain and projects such as OriginTrail are so important in bringing solutions to the web3.

The Identity of the Future (SSI) and what it can bring to IoT

During the COVID-19 confinement, there has been a three-fold increase in digital identity theft, according to figures released by the Federal Trade Commission (FTC). Sovereign identity under Blockchain technology brings benefits of decentralisation and data custody to the final user and the IoT sector by fulfilling the CIA triad. (Confidentiality, Integrity and Availability).

Blockchain-based Cloud Computing BIaaS / BPaaS / BSaaS

Blockchain and Cloud Computing are two revolutionary technologies that have the potential to change the way we live, work and interact. With the growth of big data, the need for large networks (cloud) has increased significantly. The combination of Blockchain with the cloud could further revolutionize all industries.

Trusted Smart Contracts and use with the Internet of Things.

The use of Blockchain technology will be widely used in the coming years and one of the most benefited sectors will be the IoT. Thanks to the use of tools such as smart contracts, it will be possible to automate processes in a secure, immutable and decentralized way. However, there are still some nuances to be solved for a better adoption.

Understanding Hyperledger Besu, the technology on the rise.

The project formerly known as Pantheon which is now Hyperledger Besu, enables the construction of public Blockchain through an Ethereum client and permissioned blockchain. The core development of Besu has been led by Pegasys, an engineering team linked to Consensys. Airtrace is aware that the essence of Blockchain technology is transparency but also privacy in certain aspects, which is why Besu has been chosen for building the infrastructure.

Strength in numbers. Interoperability in the Blockchain of Things (BoT) era.

Nowadays, the Internet of Things plays a very important role in our lives. The IoT makes it possible to collect and analyze data, as well as to enable machine-machine and human-machine connection. However, in the IoT sector there is a major problem to be solved if we want to expand the number of connected devices, and that is interoperability. Interoperability is an essential quality to make the IoT industry work optimally, where everything is connected to everything.

IPFS, a key point in IoT devices and the new internet.

The use of the internet and the number of connected IoT devices is growing rapidly. However, the current internet infrastructure, the apps used and the machine-machine connection, store and process data centrally using HTTP protocols and under a client-server model with certain drawbacks. The advent of Web 3.0 and decentralized systems has attracted technologies such as IPFS (Interplanetary File System) for more secure data storage and distribution. IPFS is currently used in AirTrace in ADOS and future implementations are planned.

Cloud of Things and Blockchain (BCoT) integration.

The IoT has advanced rapidly, necessitating tools such as cloud, edge computing and fog computing to improve processes. However, the centralized systems in the cloud that have been having so much control all these years are no longer starting to be liked as much as before due to the large amount of data being processed. This is why the use of blockchain together with Cloud of things (BCoT) is something that many companies see as promising.

The importance of data quality, data security and how AirTrace helps you.

Data has become part of our daily lives and an asset for companies. However, it is exposed to misinterpretation, poor quality, theft and falsification causing great damage to companies. AirTrace helps you to know the quality of the data you are getting and secures it in a decentralized way without central control.

Zero Knowledge Proof, blind trust

The digitization of many processes and the constant technological evolution bring with them many benefits, but also new possibilities for cyber-attacks. Many companies today collect a large mass of data that helps them to improve their marketing mechanisms, products and services, making them more prone to constant attacks. That is why in this article we will explain how Zero Knowledge Proof (ZKP) makes it possible to protect confidential data and increase privacy by using mathematics.

Decentralized cloud and IA model protection with iEXEC

Decentralization for cloud computing is coming on strong with a multitude of advantages. In addition, companies like iEXEC not only bring a decentralized solution for cloud resources, but also use Intel SGX to secure to further protect data. AirTrace currently uses iEXEC for the ADOS AI and distributed computing algorithm.
