Grove

Grove provides indexed storage for ordered data such that it can be efficiently queried.

You can use grove as a library either by deploying the GroveLib contract yourself, or using the one deployed at 0xd07ce4329b27eb8896c51458468d98a0e4c0394c.

Alternatively, you can interact with grove as a standalone service via the Grove contract either by deploying it yourself, or using the one deployed at 0x8017f24a47c889b1ee80501ff84beb3c017edf0b.

If you would like to verify either of the contract's source, they were compiled using version 0.1.5-23865e39 of the solc compiler with the --optimize flag turned.
