Display all versions related to the changes

Whenever a change is made, Labii Electronic Lab Notebook (ELN) and Laboratory Information Management System (LIMS) saves a new version of the record automatically. This page shows all versions related to a record.

The content display is similar to the Version widget. You can use the Version widget to insert the version information in your detail view.


A blockchain, originally block chain, is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data.

Labii is the FIRST and the ONLY company in the market that uses the blockchain technology to secure your research data. A key (Hash) is created as the signature to each version, and used to verify the connections to its previous version.

Labii utilizes the hash key (blockchain technology) of each version to ensure no alter can be made to any of the previous versions.
