Usage

The library starts as soon as the @boardname@ starts. It uses the radio.

Add a block #radioblockchainaddblock

The addBlock adds a block in the blockchain and broadcast its to peers.

blockchain.addBlock(0)

Read the values #radioblockchainvalues

Use the values block to get an array of number of the values stored in the chain, minus the genesis block.

blockchain.values()

Filtering values by @boardname@ #radioblockvaluesfrom

You can also get the values contributed by a particular @boardname@ using valuesFrom. The id block gives your @boardname@ id.

blockchain.valuesFrom(blockchain.id())

Events #radioblockchainonevent

Events are raised when the chain is updated (when you received a new chain) or broadcasted.

blockchain.onEvent(BlockChainEvent.Update, () => {})
