nearprotocol - NEAR 区 block 链中抵押的 NEAR 代币总数

Question

我需要以编程方式获取 NEAR 区 block 链中抵押的 NEAR 代币总数，就像 NEAR 浏览器中显示的那样 (https://explorer.near.org/nodes/validators)。 Total Staked in NEAR Blockchain

NEAR 提供 JSON RPC API ( https://docs.near.org/api/rpc/setup ) 以通过点击相应的 RPC 端点来获取一些详细信息。例如，我能够使用以下 RPC 结构获取质押池中质押的 NEAR 代币总数。

endpoint URL: https://rpc.mainnet.near.org
Header = {"Content-Type":"application/json"}
Body:
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "query",
  "params": {
    "request_type": "call_function",
    "finality": "final",
    "account_id": "staking pool id",
    "method_name": "get_total_staked_balance",
    "args_base64": '{"account_id": “staking account id”}’ in base64 encoding
  }
}

但没有类似的详细信息可用于获取 NEAR 区 block 链中的 Total NEAR Staked。如果有人可以帮助我，我将不胜感激。谢谢。

浏览了 NEAR 官方 API 文档(https://docs.near.org/api/rpc/setup)、NEAR 浏览器代码库(https://github.com/near/near-explorer)、NEAR 核心合约代码库(https://github.com/near/core-contracts)

Answer 1

您可以使用方法EXPERIMENTAL_validators_ordered:

curl --location --request POST 'https://archival-rpc.mainnet.near.org/' \
--header 'Content-Type: application/json' \
--data-raw '{
  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "EXPERIMENTAL_validators_ordered",
  "params": ["JD8o38fkxG34QsBS4ZwT8hieehNUeJMAPCgKGk6xnbuf"]
}'

这将返回一个包含所有验证者及其权益的列表:

{
    "jsonrpc": "2.0",
    "result": [
        {
            "account_id": "figment.poolv1.near",
            "public_key": "ed25519:7RjyY1bRKDqkshbKZtgpQdwsdxou8j9my8g1hPKZ9ngM",
            "stake": "32093438089641651528322513598448",
            "validator_stake_struct_version": "V1"
        },
        {
            "account_id": "astro-stakers.poolv1.near",
            "public_key": "ed25519:2nPSBCzjqikgwrqUMcuEVReJhmkC91eqJGPGqH9sZc28",
            "stake": "25153541134999320232972613031893",
            "validator_stake_struct_version": "V1"
        },
        {
            "account_id": "bzam6yjpnfnxsdmjf6pw.poolv1.near",
            "public_key": "ed25519:2ZJqaaCAisK4u8E2i611zFfvNmrvevovnU3M7SpGHkLY",
            "stake": "23349905747168797648450246349622",
            "validator_stake_struct_version": "V1"
        },
        ...
   ]
}
