Module property

chain core properties

define the different properties a supported chain needs to implement to work in our models.

Block

The Block is the atomic element that compose a chain. Or in other words the chain is composed of a succession of Block.

the Block trait implements the necessary feature we expect of a Block in the chain. Having a function that requires the object to implement the Block traits means that we are expecting to have only access to:

• the block and its parent’s identifier (the block hash);
• the block number, its position in the blockchain relative to the beginning of the chain. We often call this number the block Date.

Ledger

this trait is to make sure we are following the Transactions of the chain appropriately.

LeaderSelection

This trait is following the protocol of the blockchain is followed properly and determined a given instance of the LeaderSelection object is selected to write a block in the chain.

Traits

Block

Block property

BlockDate

A trait representing block dates.

BlockId

Trait identifying the block identifier type.

ChainLength

Deserialize

Define that an object can be read from a Read object.

Fragment

A fragment is some item contained in a block, such as a transaction, a delegation-related certificate, an update proposal, and so on. Fragments can be serialized (so that they can be concatenated to form a binary block( and have a unique ID (typically the hash of their serialization).

FragmentId

Trait identifying the fragment identifier type.

FromStr

Defines the way to parse the object from a UTF-8 string.

HasFragments

Accessor to fragments within a block.

HasHeader

Access to the block header.

Header

Trait identifying the block header type.

LeaderId

Trait identifying the leader identifier type.

LeaderSelection

interface for the leader selection algorithm

Ledger

Define the Ledger side of the blockchain. This is not really on the blockchain but should be able to maintain a valid state of the overall blockchain at a given Block.

Serialize

Define that an object can be written to a Write object.

Settings

the settings of the blockchain this is something that can be used to maintain the blockchain protocol update details:

State

Transaction

define a transaction within the blockchain. This transaction can be used for the UTxO model. However it can also be used for any other elements that the blockchain has (a transaction type to add Stacking Pools and so on…).

TransactionId

Trait identifying the transaction identifier type.
