The BORA 1.0, at the time of the formation of the project, was Layer2’s private blockchain based on Ethereum. By nature, the private chain has the benefits of being able to handle large-scale traffic and facilitate the ease of use of the service. However, a private ecosystem is closed off and, due to this, has the drawback of limited scalability. The BORA Team had considered linking with Ethereum’s various projects but faced the reality that it would be difficult to expect active participation just for BORA that has a private nature in the large Ethereum ecosystem.
