Blockchain Security – Aligning to Upcoming Digital Business Initiatives

Accenture and Leading Financial Institutions Call for Applicants for the Asia-Pacific FinTech Innova

The development and implementation of digital business initiatives are becoming increasingly necessary in today’s world. As companies strive to remain competitive, they must stay on top of the latest technology and ensure their data is secure. Blockchain technology is a key component of this process, as it is a powerful tool that provides a safe, distributed ledger system that can help secure the integrity of data and transactions.

However, as organizations move towards more complex digital initiatives, such as the e-Residency project of the government of Estonia, they must ensure their blockchain security measures are up to date. Below, you will find an overview of the benefits and challenges associated with blockchain security, along with outlined strategies for mitigating these risks and ensuring successful implementation.

Join us as we discuss the importance of staying up to date with changes in this technology and the implications for businesses in terms of data security and privacy and learn more about the future of blockchain.

What Is Blockchain?

A blockchain is a digital, decentralized ledger that records transactions on many computers across the globe in a secure, tamper-proof way. When a transaction occurs, it is combined with other transactions to form a block, which is then added to the end of the blockchain. Each block contains a cryptographic hash of the previous block, which links the blocks together and prevents any interference.

Since all transactions are recorded on a public ledger, blockchain technology can be used to track ownership, verify identity, and ensure the authenticity of data. Jaryd Krause, a digital assets expert from, notes that this makes it an attractive option for various startups and business initiatives.


The main benefits of blockchain technology are decentralization, immutability, and enhanced security and efficiency.

Decentralization refers to the fact that the ledger is not stored in a single location but is distributed across a computer network instead. This makes it more resistant to tampering or deleting, as there is no central point of failure.

According to Google, “instead of relying on a central entity to validate and store data, the governing infrastructure of a blockchain is a node – a device, such as a computer, laptop, or server, that contains a full copy of the transaction history of the blockchain.” This is a blockchain’s major advantage over traditional centralized systems, which are vulnerable to hacks and data breaches.

Immutability means that once a transaction has been recorded on the blockchain, it cannot be altered or removed. This is due to the fact that each subsequent block contains a cryptographic hash of the previous one, meaning that any change would be immediately apparent.

Security is achieved through the use of cryptography. Each transaction is encrypted and requires a digital signature in order to be verified. This makes it very difficult for anyone to falsify the data.

Not to forget increased efficiency. Traditional systems often require third-party intermediaries like banks to verify and approve transactions. This can slow down the process and add unnecessary costs. With blockchain technology, transactions can be quickly verified and approved by the network of computers, significantly reducing costs and speeding up the process. What’s more, building apps that run on the blockchain can speed up all kinds of business processes – here, you can find a Blockchain development guide.


Despite the many benefits of blockchain technology, there are also some challenges that need to be considered:

Scalability. The decentralized nature of the technology means that each computer in the network must process and store the entire blockchain. As the number of users on the network increases, so does the amount of data that needs to be held on the blockchain. This can lead to the network becoming overloaded and slowing down.

Governance. Because there is no central authority, it can be difficult to make changes to the protocol, potentially leading to stagnation, which could eventually make the network less attractive to users. Plus, since the technology is still relatively new, there is a lack of clarity about regulating it. As such, it could get tricky for businesses to comply with regulations later on, possibly resulting in fines or other penalties.51% attacks. These occur when a group of miners controls more than 50% of the computing power in the network and can therefore manipulate the blockchain. This can result in double-spending – i.e. when a user spends the same cryptocurrency twice. While this type of attack is rare, it is a serious concern for those using blockchain technology.

How to Mitigate Risks and Ensure Alignment

Despite the challenges, blockchain technology remains a powerful tool for businesses when used correctly. In order to mitigate the risks and ensure alignment with upcoming digital business initiatives, it is essential to implement proper security measures.

Below, we outline some key strategies for doing so:

  • Choose a scalable platform
  • Work with regulators
  • Implement strong KYC (know your customer)
  • Ensure that the private keys used to access the blockchain are stored securely.
  • Educate employees.

Wrapping Up

Blockchain technology can provide a number of benefits for businesses, including enhanced security, efficiency, and transparency. However, as with any new technology, there are also some challenges that need to be considered. This is especially important for organizations that move towards more complex digital initiatives, be it passports confirming the authenticity of digital products or an e-identity initiative.

In order to ensure successful implementation, it is essential to put in place proper security measures from the outset – only then will your startup be able to fully reap the benefits of this game-changing technology.
