We are now pushing ahead with the introduction to Abstract Layer Design. The production child chain has been refactored to support newer transaction types, meaning that any new transaction features we would like to accommodate in the future can be included without too much complexity. The changes to the root chain contracts are well underway with standard exits having already been implemented.

In order to ensure that the plasma security model will continue to work as expected under high load, we have started a new set of test suites to mock root chain exits and byzantine behaviors.

Currently the whole UTXO model has been found to be very confusing for end-users and integrators, especially with regards to the life cycle of the exit processes. To alleviate this pain, we begin to implement new APIs and change the data model to allow for easy visualization of UTXOs as they begin their exit.
