What’s More Secure: Blockchain Or Database?

Data storage options database and blockchain are architecturally different and come with their own sets of advantages, vulnerabilities, and challenges. Data storage is based on client-server-based architecture and can function in small and large scale environments.

Blockchain storage is decentralized storage based on a peer-to-peer network of a distributed ledger. Each block stores the hashed information from the previous block, secured by cryptographic security. Data is stored in uniform-sized blocks that can be traced back to the first block.

Blockchain has no controlling infrastructure and is completely decentralized. It is composed of unbreakable rules and laws which don't require regulation. Data breaches are grave- they can cause damage to intellectual property and make clients lose trust in an organization. In the blockchain, trust in the network is the only factor in transaction and data storage.

Blockchain and databases are susceptible to data theft and have vulnerabilities. Public and private blockchains run the risk of 51 percent attack by a group of miners who control more than 50 percent of the hashing rate of the network. Data backups are threatened by malware, but they become more vulnerable to attacks when data volume becomes large enough to be scalable.

To boost trade, Africa is simplifying international payment systems

It's hard to transfer money between African countries. The Ghanaian king settled a bill with a Nigerian attorney. His experience highlights a systemic problem impeding Africa's economic growth: high transaction costs and inconvenience. 15% of all imports and exports occur between 55 African countries. 60% of Asian trade is within Asia. 70% in EU. The difficulty of international payments hinders African trade. There are also high tariffs, long border procedures, and congested roads. Proponents of AfCFTA say easing trade restrictions will boost trade, FDI, and economic growth. 50 million people will be lifted out of extreme poverty by 2035 due to the accord's positive impact on real income, which is projected to rise 9.1%. Another issue: In Africa, currency values fluctuate. From July 2021 to 2022, Ghana's currency fell from 6 to 8. Volatile currencies make financial transactions more costly and risky. To overcome these problems, PAPSS facilitates financial transactions ...

A more accessible blockchain-based app dev in progress

Outside of cryptocurrency, blockchain has a lot of potential. Decentralized applications and distributed ledgers may soon be used by established industries such as finance, automotive, supply chain, and mobility. However, creating your own blockchain from the ground up is quite tough. Lisk co-founder Max Kordek discusses how to make decentralization more approachable. Blockchain's decentralized, tamper-proof nature has the ability to decentralize power and offer the collective hive more data control. Data from different manufacturers may be linked, and data from different vehicles could be shared. With so much money pouring towards asteroid mining and Mars expeditions, an interplanetary economy appears to be a foregone conclusion. Established businesses are less likely to have a say in the change than new entrepreneurs. When Bitcoin was first launched, the development ecosystem was "terrible," according to Kordek. He claims that developing on the open source and immutable...

Embracing blockchain as a tool for change

Blockchain technology is increasingly being employed in enterprises outside of the financial industry, and this trend is expected to continue in the future. By 2023, it is estimated that investment in blockchain technologies will reach US$16 billion per year on average. (Approximately RM68 billion). To put this in perspective, consider the fact that US$8.7 billion was invested in blockchain and cryptocurrencies in the first half of 2021. The Malaysian government is aiming to create a long-term environment for the country's technology and financial services industries in the next years. Founded in Singapore in July 2021 by Iskandar Investment Bhd as a wholly-owned subsidiary, the Ignite Global Innovation and Technology Exchange will be the world's first global innovation and technology exchange. In Malaysia, IIB Ventures Sdn Bhd is in charge of the development of the blockchain industry's ecosystem. This is why BV@M has set a goal of creating a blockchain ecosystem in Medini...
