Best Aleph Zero Testnet RPC Nodes, APIs and Blockchain Node Hosting

Aleph Zero is an enterprise-ready, high-performance public Proof-of-Stake blockchain platform based on a novel, Directed Acyclic Graph (DAG)-based consensus protocol that has been peer-reviewed and presented at an ACM conference. The protocol has been integrated with a customized Substrate stack to ensure rapid time-to-market. What's worth noting is that while DAG is being utilized as an intermediary data structure resulting in more secure and faster data ordering, Aleph Zero produces a blockchain in the end. The next step is to enable privacy-enhancing features based on secure multi-party computation research and zero-knowledge proofs.
