10 Things Every Blockchain Engineer Should Know in 2020

10 Things Every Blockchain Engineer Should Know in 2020

The usefulness of blockchain is more than being a support to Bitcoin (BTC) or cryptocurrencies only. The application of blockchain in several industries is numerous. Despite the technology’s restrictions and challenges, and the demand for blockchain increased more by 500% between 2018 and 2019. 

Lots of engineers can’t wait to be a part of the blockchain movement. 

Blockchain engineers can be more successful and stay ahead of their game if they know the ten aspects of the industry. Perhaps not all of them, but the more they have a solid knowledge, the better. And they include:

Lightning Network

Lightning Network was released to provide a solution to the blockchain’s problem, which is the scalability problems, although it has its challenges too. Based on the conclusion of a research paper titled “Lightning Network: A Second Path Towards Centralisation of the Bitcoin Economy,” that says, network has its security weaknesses due to improved centralization. 

But, the blockchain engineers are doing everything possible to destroy this problem.


DeFi is otherwise known as either Decentralized finance or open finance, and it provides various financial services like trading, borrowing, insurance, savings, loans, lending, and also on public blockchains. 

DeFi offers lots of benefits when compared to a legacy financial service. Based on the analytics site Defipulse, the entire value put into DeFi exceeds $1.2 billion in February 2020. Decentralized finance is improving and also has the ability to reach everyone who owns a smartphone.

An evolving industry needs flexible engineers

The height of blockchain’s reach is yet unknown. Most people referred to the technology as a “hammer looking for a nail.” Some crypto newbies have been evaluated for using blockchain where an easy solution could have been enough.

What is obvious and plain is the rate at which the technology is being incorporated. Currently, CargoSmart is working alongside with the COSCO SHIPPING LINES and electric car manufacturer Tesla to examine a blockchain supply chain pilot project.


Blockchain-as-a-Service (BaaS), is a controlled blockchain model that enables engineers to develop blockchain applications and other digital services over a dispensed network. In this model, the industry offers infrastructure and blockchain-developing tools. 

The BaaS model offers an auditable transaction record, a middleware for checking application development, a modular and an arranged network and infrastructure, and a platform architecture management.

Blockchain Interoperability

Blockchain Interoperability is the ability of separate blockchains to access, see and share information with one other. Although present blockchains are separated and siloed from the next one.

They are self-standing probably due to several competitions. Most professionals debate that blockchain interoperability will cause a massive success in the sector. E.g., payment platforms like PayPal, which can work reliably with other mobile payment apps. A connection has to be developed, for instance, between Bitcoin and Ether (ETH).


It is also referred to as malicious crypto mining. It is a rising online threat that includes malicious mining of cryptocurrencies on a victim’s device. Although crypto mining’s ability hasn’t yet been examined adequately, there has been a significant increase in crypto-jacking instances. 

It’s good to discover and stop crypto-jacking through network monitoring devices because the threats are not discovered easily by endpoint solutions. That’s why lots of businesses and organizations have network monitoring devices.


DAML (Digital asset modeling language), is known as a smart contract language that allows blockchain engineers to code multi-party agreements for several blockchains in the right way. DAML is an open-source and anticipated to make use of enhanced developer experience and offer front-end support and ledger model advancements in 2020. 

As the need for enhanced blockchain systems increases, blockchain technology keeps transforming.

Federated Blockchain

Blockchain is of a benefit to lots of organizations and a cause a negative impact on organizations that deal with important sensitive information. The breakthrough of federated blockchain has brought relief to these organizations. 

A federated blockchain is a private and authorized blockchain where individual members become members of the network by way of voting or advance approval. The reason why all engineers should be ready for this feat is that this is the year of federated blockchain.


The Internet of Things or IoT sector has importantly become successful these days. Based on the research made by Gartner, it estimates that the total number of IoT devices will attain about 20 billion in 2020. IoT connects “things,” people, sensors, and products, with data as the standard denominator amidst them. 

Well, this is interesting, although it must be noted that various security weaknesses can be used. Blockchains can be used to authenticate and transfer data in an IoT system without the help of a third party.

Blockchain-based supply chain

A supply chain is essential to lots of organizations. Blockchain helps in enhancing traceability, decreasing inauthentic goods, improve transparency, and redefine traceability in supply chains. 

The dispensed ledger technology records major product information like the origin of the raw material, the raw materials used in manufacturing products. Consumers have the ability to use this information to confirm the authenticity of the products. Blockchain is set to improve supply chains later on.

Transferable Skills

Blockchain develops on other technologies. This emerging space needs skilled and professional engineers in software development, cryptography, programming, web applications, and data analytics, etc. A skill won’t be sufficient to give an engineer an edge over others. Although the combination of skills in various areas is highly required as new conceptions are brought into the industry daily.

It is not a myth that lots of blockchain engineers have a lot to learn and also improve their skills and knowledge to be able to give back to the industry. Hopefully, the tips above would add to the knowledge they already possess.
