graph-node VS cardano-node

A subgraph according to The Graph (which is a decentralized protocol for indexing and querying blockchain data) is a custom API built on blockchain data. They are queried using the GraphQL query language and are deployed to a Graph Node using the Graph CLI.

Event is a log entity which EVM smart contracts can emit during transaction execution. Events are very good at signalling that an some action has taken place on-chain. Applications can subscribe and listen to events to trigger some off-chain logic or they can index, transform and store events in some off-chain storage (look at The Graph protocol or Ethereum ETL).

The Graph

There are also decentralized network services like The Graph or Pocket Network that provide decentralized access to Ethereum and other blockchain networks. Note that these services primarily provide APIs for querying blockchain data, and may not provide full functionality for sending transactions or executing smart contracts like a full Ethereum node or services like Infura and Alchemy.

For read-only the way to use The Graph

See it for yourself.

thegraph.com is the only site operated by The Graph Foundation, and is the centrepiece for all activity on the protocol. Can a website/web dApp be hacked? Yes. Has it been hacked in the past two years since it launched? No.

Cardano (ADA) – The Sustainability-Focused Blockchain

Hoskinson decided to support Ethereum classic after that and also launched Cardano.

This sluggish activity is hitting smaller cryptocurrencies like Cardano and Solana, which are seeing much slower growth than bitcoin. Trading platforms popular with retail investors, such as Robinhood, are moving to end support for trading these tokens, and the risk of an SEC crackdown has made institutional investors even more leery of them.

Cardano Node 8.1.1 is out. https://github.com/input-output-hk/cardano-node/releases/tag/8.1.1

Documentation on that can be found in https://github.com/input-output-hk/cardano-node/blob/master/doc/reference/configuring-a-node-using-yaml.md and https://github.com/input-output-hk/cardano-node/blob/master/doc/reference/cardano-governance.md.
