Prize Title

Rosetta Node API for Vite

Prize Bounty

$3000 in VITE + VITE merch

Challenge Description

Looking for someone to build the Rosetta Node API for Vite (https://vite.org). Vite is an asynchronous, message-driven blockchain using a high-performance DAG-based ledger structured called block-lattice.

Rosetta is an OpenAPI standard (https://www.rosetta-api.org/docs/welcome.html) that makes integrating with blockchains simpler, faster, and more reliable. The Rosetta API is made up of 2 core components, the Data API and the Construction API. See Rosetta Data API Overview and Rosetta Construction API Overview for details.

You can use any convenient programming language to implement the API. Rosetta provides the rosetta-sdk-go (https://github.com/coinbase/rosetta-sdk-go) to facilitate the work, which means if you are familiar with Golang, you could save a lot of time by using the SDK.

Future maintenance is not required after the final approval of your work.

Submission Requirements

• The complete project should include a full implementation of all endpoints defined in the Data API and the Construction API, Docker deployment, and all source code
• The API must pass the rosetta-cli (https://www.rosetta-api.org/docs/rosetta_cli.html) validation
• All submissions, including all code, must be open source for future use and reference by the community, and links to external documents must be provided in the Github repo submission
• We will require a demo of the submission

Judging Criteria

• The Vite team will run tests to make sure basic functions perform as required
• The code submitted will be subjected to a review for extensibility, organization, proper documentation

Winner Announcement Date

• The Vite Labs team will schedule a demo after receiving the submission. And a winner will be announced within 48 hours after the demo

Vite Rosetta API Implementation Guideline

 Vite Rosetta API Implementation Guideline

 Network

 /network/list

Returns a list of NetworkIdentifiers that the Rosetta server supports.

 Vite Rosetta API Implementation Guideline

 Network

 /network/list

Returns a list of NetworkIdentifiers that the Rosetta server supports.

Input example:

{
    "metadata": {}
}

Output example:

{
    "network_identifiers": {
        "blockchain": "vite",
        "network": "mainnet"
    }
}

- The Rosetta server should identify what environment it is deployed in. The "network" field should be "testnet" or "mainnet". 

 /network/options

This endpoint returns the version information and allowed network-specific types for a NetworkIdentifier. Any NetworkIdentifier returned by /network/list should be accessible here.

Input example:

{
    "network_identifier": {
        "blockchain": "vite",
        "network": "mainnet"
    },
    "metadata": {}

        "call_methods": [
        ],
        "balance_exemptions": [
        ],

}

- "REQUEST" includes sending a transfer or calling a smart contract. - "RESPONSE" stands for receiving a transfer or executing a contract function.  - "MINT" is the Coinbase transaction, including issuing SBP rewards and minting new token.  - "errors" should include all error types that could be used by the API. 

 /network/status

 Block 

 /block

Get a block by its Block Identifier. If transactions are returned in the same call to the node as fetching the block, the response should include these transactions in the Block object. If not, an array of Transaction Identifiers should be returned so /block/transaction fetches can be done to get all transaction information.

Input example:

{
    "network_identifier": {
        "blockchain": "vite",
        "network": "mainnet"
    },
    "block_identifier": {
        "index": 59006949,

            "version": 9
        }
    }
}

- On Vite, a block indicates snapshot block, not account block. An account block is a transaction, and will be used in /block/transaction.  - Use snapshot block related API, such as ledger_getSnapshotBlockByHash or ledger_getSnapshotBlockByHeight. 

 /block/transaction

Get a transaction in a block by its Transaction Identifier.

 /construction/metadata

Get any information required to construct a transaction for a specific network. Metadata returned here could be a recent hash to use, an account sequence number, or even arbitrary chain state. 

Input example:

{
    "network_identifier": {
        "blockchain": "vite",
        "network": "mainnet"
    },
    "options": {
        "account_identifier": {
                "address": " vite_1737bb7abc4883cc2f415a804f80274d3a725a68a5bee5bad3",
            },
        "fetch_previous_block": "true",
        "use_pow": "true"
    }
}

Output example:

{
    "metadata": {
        "height": 23,
        "previousHash": "2870a345482ab4382bfe9e6f56f916874582b23591487eb3e7e78405de5a41f2",
        "difficulty": "67108863",
        "nonce": "FWC0X7Za7HE="
    }
}

- "account_identifier" indicates from which address the transaction will be sent. - "account_block_height" and "previous_block_hash" are required to construct a transaction. You should get them from the blockchain by calling     1.  [RPC] ledger_getLatestAccountBlock or      2.  [Vite.js] getPreviousAccountBlock in AccountBlock class - "difficulty" and "nonce" should be returned if “use_pow” is “true” in the request. "difficulty" can be obtained by calling ledger_getPoWDifficulty, and "nonce" is from util_getPoWNonce. If “use_pow” is not set, the two fields should not be populated. 

 /construction/payloads

Payloads is called with an array of operations and the response from /construction/metadata. It returns an unsigned transaction blob and a collection of payloads that must be signed by particular AccountIdentifiers using a certain SignatureType.

- On Vite, there is request transaction (A sends to B) and response transaction (B receives a tx from A). If "blockType" is 2, it is a request transaction. In this case, "sendBlockHash" is not required. For response transaction (having "blockType" 4) , "sendBlockHash" must be present. - For constructing a response tx, in other words, receiving a transaction sent by others to you, you should call ledger_getUnreceivedBlocksByAddress to get the un-received tx list, then populate "sendBlockHash".  - "unsigned_transaction" is the raw transaction string in Base64, simply converted from the account block object. For example, 

Buffer.from(JSON.stringify(accountBlock), "utf8").toString('base64')

- "hex_bytes" is the raw payload. For example, you can use Buffer.from(payloads.payloads[0]).toString('hex') to populate this field. 

 /construction/parse

Parse is called on both unsigned and signed transactions to understand the intent of the formulated transaction. This is run as a sanity check before signing (after /construction/payloads) and before broadcast (after /construction/combine).

Combine creates a network-specific transaction from an unsigned transaction and an array of provided signatures. The signed transaction returned from this method will be sent to the /construction/submit endpoint by the caller.
