范例

打开所有单元 关闭所有单元

基本范例  (1)

显示 $BlockchainBase 的当前设置：

Wolfram Language code: $BlockchainBase

BlockchainData 将使用 $BlockchainBase 的当前设置：

Wolfram Language code: BlockchainData[]//Dataset

更改设置：

Wolfram Language code: $BlockchainBase = "Ethereum"

现在 BlockchainData 将返回以太区块链的元信息：

Wolfram Language code: BlockchainData[]//Dataset

范围  (6)

获取比特币测试网区块链的最后一个区块：

Wolfram Language code: $BlockchainBase = {"Bitcoin", "Testnet"}
Wolfram Language code: BlockchainBlockData[-1]//Dataset

更改设置：

Wolfram Language code: $BlockchainBase = "ARK"

现在 BlockchainData 会返回 ARK 区块链的元信息：

Wolfram Language code: BlockchainData[]//Dataset

改变设置：

Wolfram Language code: $BlockchainBase = "bloxberg"

现在 BlockchainData 将返回 bloxberg 区块链的元信息：

Wolfram Language code: BlockchainData[]//Dataset

改变设置：

Wolfram Language code: $BlockchainBase = "Tezos"

现在 BlockchainData 将返回 Tezos 区块链的元信息：

Wolfram Language code: BlockchainData[]//Dataset

改变设置：

Wolfram Language code: $BlockchainBase = "Cardano"

现在 BlockchainData 将返回 Cardano 区块链的元信息：

Wolfram Language code: BlockchainData[]//Dataset

用 Tezos 链 ID 来指定网络：

Wolfram Language code: chainID = BlockchainData["ChainID", BlockchainBase -> "Tezos"]
Wolfram Language code: $BlockchainBase = {"Tezos", chainID}
Wolfram Language code: BlockchainData[]//Dataset

可能存在的问题  (1)

使用来自于主网网络的交易 ID 从比特币测试网获取交易信息会返回 Missing["NotAvailable"] 输出：

Wolfram Language code: $BlockchainBase = {"Bitcoin", "Mainnet"}
Wolfram Language code: txid = RandomChoice[BlockchainBlockData[-1, "TransactionList"]]
Wolfram Language code: $BlockchainBase = {"Bitcoin", "Testnet"}
Wolfram Language code: BlockchainTransactionData[txid]
