Blockchain Security: How to Improve Blockchain Technology Security and Transaction Data

by Jaynifer Son Web Developer

The blockchain development which is control bank transaction data along with investment firms.

  • Eliminate the need for centralized control and the additional costs
  • Trust is distributed between blockchain members
  • Transactions are digitally signed using an asset owner public/private key pair
  • Once recorded, data in a block cannot be altered retroactively
  • Open, distributed ledgers record transactions between two parties efficiently and in a verifiable and permanent way
  • Transactions don’t have to be just data – they can also be code or smart contracts

Blockchain Security Block Doesn’t Develop Equally

A smart contract is a computer program that describes an agreement with the ability to self-execute and enforce the terms of a contract. If the blockchain is breached, a smart contract can be altered, breaking the trust of the blockchain and removing the ability for two parties to conduct business without the need for a middleman.


Securely self-execute the terms of a contract with anonymous parties through strong authentication and storing your encryption keys in a hardware root of trust, ensuring the parties are properly identified and that no one can access your data.


The restrictions imposed by a traditional central-authority trust model have helped make the IoT vulnerable. Most notably Mirai-style botnets, which recently allowed hackers to easily take over thousands of IoT devices. Only protecting the IoT devices with default passwords allowed hackers to launch Distributed Denial of Service (DDoS) attacks.

Distributed Decentralized Blockchain Security Storage

Within a permissioned blockchain transactions are validated and processed by participants that are already recognized by the ledger. Even though this is the case, there is still a challenge and issue of trust. How can one ensure the blockchain is secure and trustworthy in order to avoid the substantial impact of a cyberattack? The answer is by building security into your blockchain technology from the start, through strong authentication and cryptography key vaulting.

The Infrastructure of Blockchain Security

The designed to store the private keys used by blockchain members to sign all transactions in a FIPS 140-2 Level 3 dedicated cryptographic processor. Keys are stored throughout their lifecycle, ensuring cryptographic keys cannot be used by unauthorized devices or people. Cryptographic keys kept in software are at risk of theft which compromises the entire blockchain ledger.
