Introduction

The Kaspa blockchain is a high-performance, proof-of-work (PoW) cryptocurrency designed for scalability and fast transaction processing. It utilizes a unique data structure called a blockDAG (Directed Acyclic Graph), which allows multiple blocks to be created and processed in parallel rather than a traditional linear chain. This architecture makes Kaspa capable of handling high transaction throughput while maintaining robust security.

Key features of Kaspa include:

• Fast Block Times: Blocks are generated every second, enabling rapid transaction confirmation.

• Scalability: The blockDAG structure improves scalability compared to traditional blockchains.

• Decentralization: Maintains a high level of decentralization through PoW consensus.

• Fair Launch: No premine or ICO; it was launched fairly through mining.

Kaspa is designed to provide an efficient, decentralized solution for payments and value transfer while addressing the scalability issues faced by many first-generation blockchains.

How to Interact

1. Get your API Key from DevTools.

1. Get the proto files needed to define the gRPC service:

   1. messages.proto

   2. rpc.proto

2. Place them into a folder together, e.g. /proto

3. Download and install a grpc client, like grpcurl

4. Test the query as follows:

grpcurl \
  -import-path ./proto \
  -proto messages.proto \
  -d '{"id":1, "getSystemInfoRequest":{}}' \
  -H "apiKey: {apiKey}" \
  grpc-mainnet-kaspa-fullnode.forbole.com:443 \
  protowire.RPC/MessageStream
