[A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.](https://en.wikipedia.org/wiki/Blockchain) The application of blockchain technology in healthcare has been largely discussed. Andy Lippman, a senior research scientist at MIT, [created a blockchain to allow patients to cryptographically sign their own data. ](https://medium.com/s/welcome-to-blockchain/what-could-blockchain-do-for-healthcare-59c17245448e)The blockchain technology has made the healthcare data more secure, enabling the patient to take control.\

In academic, biotech, or even pharmaceutical settings, scientists are still slow in adopting new technology. Labii, as a pioneer in developing ELN & LIMS technology and providing online documenting services, is applying blockchain technology to [its newest version](https://www.labii.com/blogs/new-version-of-labii-eln-lims-v3-is-on-beta-testing/) for [Electronic Lab Notebook](https://www.labii.com/electronic-lab-notebook-eln).\
\
Security in [ELN and LIMS](https://www.labii.com/) is always the first concern. [Blockchains are secure by design and exemplify a distributed computing system with high Byzantine fault tolerance.](https://en.wikipedia.org/wiki/Blockchain) Blockchain-based [electronic lab notebook](https://www.labii.com/electronic-lab-notebook-eln) will be almost impossible to hack as well as to manipulate any historical data. This will bring an externally strong security to the [Labii ELN and LIMS](https://www.labii.com/).\
\
More details of Blockchain-based Labii ELN & LIMS will be revealed, in the meantime, it is available for testing at <https://www.labii.com/signup>\
