2 years ago This can be handled by the HAMT device provided by IPLD. There is still a thruput limit, as to how many actions can be sent to the children during any given block, however overcoming a write bottleneck means probably more child chains should be explicitly made.
Mechanism to allow a chain to have unlimited children by using other chains as a proxy when the chaincount gets high. This proxy means that executions can move to other block producers in a sharding like fashion, as well storage can be sharded by proxy chainId.
