GRS RPC Explorer testnet 3.2.0 released

[jackielove4u]

GRS RPC Explorer Testnet: Simple, database-free Groestlcoin testnet blockchain explorer via RPC to Groestlcoin Core.

GRS RPC Explorer testnet is a simple, self-hosted explorer for the Groestlcoin testnet blockchain, driven by RPC calls to your own Groestlcoin testnet node. It is easy to run and can be connected to other tools (like ElectrumX) to achieve a full-featured explorer.
Whatever reasons one may have for running a full node (trustlessness, technical curiosity, supporting the network, etc) it's helpful to appreciate the "fullness" of your node. With this explorer, you can explore not just the blockchain database, but also explore the functional capabilities of your own node.
