About one and a half years ago, PLS Token start to migrate to the new network of Ethereum and the roadmap and goal has changed then, the new PLS token now exist as pure ERC-20 Token, and could have other usage/swap/stake using in future features. The auto migration support will stop after April 15th 2019. After that, there might be two months of more mannual migration support on request to mail firstname.lastname@example.org, all token migration will stop after June 15th 2019.
Please start migration ASAP if your PLS has not been migrated yet, Go to the migration guide and follow the step to finish the migration!
The migration process have been running for 1.5 years, last year Canonical announced that Ubuntu 14.04 would reach End of Life on April 30, 2019. Because most of the DACPLAY 2.0 nodes are running on ubuntu 14.04, support of latest ubuntu requires code changes and testing, support is no longer secure and cost effective afterwards. So the maintance of the auto migration service will be stoped at the same time, before April 15th. After that, there might be two more months of manual support.
After the migration stop, the usage of the ERC-20 PLS token might be used in areas of other token swap, exchange, airdrop, in the form of smart-contracts. Protocols and application chain is possible but not promise, depend on the available resources and ecosystem development of game assets and blockchain tech.
