Assalamualaikum

| - | Greetings to you all!! Blockchain integrity is one of the most crucial thing and that's why for maintaining the integrity of blockchain there are some hardwares which are used and I am going to share them in detail. ![pexels-photo-5980743 (2).jpeg](https://cdn.steemitimages.com/DQmRLGohcm17o76GgJ5jT8thMgx7oSyWH9dkTUd2CZmrxdC/pexels-photo-5980743%20(2).jpeg)[Pexels](https://www.pexels.com/photo/selective-focus-of-a-bitcoin-on-laptop-computer-5980743/) **Hardware Security Modules** This is first hardware which is hardware security modules and these are the devices which provides storage and management for cryptography keys. These are some of the hardwares designed for the protection of private information and data and they perform cryptography operations in secure way. Hardware security modules are used for securing private fees that are linked with blockchain transactions so it gives more integrity and confidentially to the keys. **Trusted Platform Modules** Trusted platform modules are another type of hardwares that are basically integrated circuits for providing secure environment for storing cryptographic keys and for performing cryptography operations or tasks.These are embedded in computer systems for the enhancement of blockchain application security. Trusted platform modules responsible for maintaining integrity of system and for protection against any unauthorised alternations that make it suitable for blockchain related sensitive data security. **Secure Elements** If I talk about secure elements then these are basically small chips which are resistant to any kind of temper and these are commonly present in the form of Smart cards SIM cards etc. All these are helpful in providing security for storing sensitive information and for performing cryptographic operations. Secure elements are very helpful if you want to store your private keys which are associated with transactions of blockchain because secure elements gives you surety that your keys remain safe secure and confidential with integrity. **Hardware Wallets** When I talk about hardware wallets then these are basically physical devices that again used for the purpose of storing private keys and these wallets are most commonly offline and are providing extra layer or double layer of protection from online related to manipulation. Hardware wallets add important for generation and creation and storing of private keys within device and it gives surety that they are never reveal internet. In this way blockchain related affects remains secure by the management by hardware wallets. **Secure USB Drives** Secure usb drives is another form of hardware that is used for securing and storing sensitive and private information and these are encrypted devices used for storage and there is hardware based encryption used in them as well as authentication mechanism also applied and implemented for data protection and their storage. Private keys encrypted are some of the blockchain related sensitive information and Private data that remain stored by the use of secure USB drive as well as if drive is lost suppose or someone tries to stole it then still get our remain safe and secure. ![pexels-photo-8369648.jpeg](https://cdn.steemitimages.com/DQmdkSPzYA25X4u2PPSih9z6pgXJdPcm68xy2VDjYoyiqKM/pexels-photo-8369648.jpeg)[Pexels](https://www.pexels.com/photo/selective-focus-photo-of-silver-and-gold-bitcoins-8369648/) These were some of the hardware solutions for maintaining the integrity and security of data and for the enhancement of integrity and there are different strengths and challenges associated with these hardwares so before choosing any hardware it is important that you should understand about hardware which is completely fulfilling your requirements whatever you want. There are multiple factors at which blockchain security depends like there should be secure hardware, there should be robust software,there should be proper implementation practices and if your data is too much and you want much security of it then it is much important that you should take suggestions of security experts so that you may stay updated about latest practices for integrity of blockchain data. |

Have a blessed day
