Ternoa Dictionary records all the native substrate on-chain data of the Ternoa blockchain: blocks, extrinsics, and events. It is a glossary of data that pre-indexes chain events, drastically improving the overall indexing performance.
Don't forget to have fun with it, Cheers 🍻
Table of Contents:
Ternoa is a Decentralised, Open source, NFT-centric Layer 1 blockchain that is multi-chain by design and aims to provide a technical stack to build scalable and secure NFTs with native support for advanced features.
NFTs native to our chain can be minted using High-level programming languages and doesn't require smart contract functionality.
With native support for Secret NFTs, Delegating and Lending, Transaction Batching and much more, you might want to give it a try.
The Dictionary acts as the middleman between the Blockchain and the Indexer. This allows the Indexer to query a block’s metadata from the dictionary, allowing one to query blocks for specific events and only return the required blocks. For example: If one wants to fetch NFT creation events only, the Indexer will ask the dictionary for the corresponding blocks, returning only the blocks where NFT creation took place (for example: 5, 9, 32, etc.) instead of all of the blocks (lets say 1 - 100).

# The indexer and dictionary should be on same version.Install the required dependencies for the project using:
yarn installGenerate types from your GraphQL schema and Operations:
yarn codegenCreate an Executable version of your project:
yarn buildPull the latest versions of the Docker image using:
docker-compose pullRun your compiled app with Docker using:
docker-compose upWait a couple of seconds for the indexing to start, after that you can access the Blockchain data in your local GraphQL playground
You can significantly improve the indexation performance by using a dictionary endpoint instead of targeting the blockchain directly to gather data.
Just make sure to select the correct endpoints for the desired networks:
As you can see that the endpoints for Networks are structured as wss://xxxxxxxx.ternoa.com and https://dictionary-xxxxxxxx.ternoa.com which is replaced by the Network designation.
Supported dictionary environment networks are Mainnet and Alphanet.
For use on Mainnet:
genesisHash: '0x6859c81ca95ef624c9dfe4dc6e3381c33e5d6509e35e147092bfbc780f777c4e'
endpoint: 'wss://mainnet.ternoa.network'For use on Alphanet:
genesisHash: '0x18bcdb75a0bba577b084878db2dc2546eb21504eaad4b564bb7d47f9d02b6ace'
endpoint: 'wss://alphanet.ternoa.com'Ternoa Explorer is an example of a project relying on Ternoa Dictionary. It enables you to visualize the on-chain activity, explore public addresses and their transaction histories, gather information about individual blocks and much more.
