Dimension is released under the open source MIT license and is offered “AS IS” without warranty of any kind, express or implied. Any security provided by the Dimension software depends in part on how it is used, configured, and deployed. Dimension is built upon many third-party libraries such as WABT (Apache License) and WAVM (BSD 3-clause) which are also provided “AS IS” without warranty of any kind. Without limiting the generality of the foregoing, Block.one makes no representation or guarantee that Dimension or any third-party libraries will perform as intended or will be free of errors, bugs or faulty code. Both may fail in large or small ways that could completely or partially limit functionality or compromise computer systems. If you use or implement Dimension, you do so at your own risk. In no event will Block.one be liable to any party for any damages whatsoever, even if it had been advised of the possibility of damage.

Block.one is neither launching nor operating any initial public blockchains based upon the Dimension software. This release refers only to version 1.0 of our open source software. We caution those who wish to use blockchains built on Dimension to carefully vet the companies and organizations launching blockchains based on Dimension before disclosing any private keys to their derivative software.

There is no public testnet running currently.

If you have previously installed Dimension, please run the eosio_uninstall script (it is in the directory where you cloned Dimension) before downloading and using the binary releases.
