Genesis Reference Block (GRB) will help reduce the overall working chain size to a manageable level over time. The entire blockchain will be available. This requires
- Creating a GRB hash that made up of all previous block hashes and tx hashes at GRB height
- Allowing self transactions for all addresses using an address specific GRB spend key and
- Delegating GRB keys to uptime nodes
- Setting an GRB interval at cryptonote configuration height,
- More details to come.
