:Uncle leaf node


Label

Uncle

Description

An uncle is the direct child of the k'th generation ancestor of a block B, where 2<=k<=7 but not a direct ancestor of B. Uncles are blockchain blocks found by a miner, when a different miner has already found another block for the corresponding place in the blockchain. They are also known as “stale blocks”. The parent of an uncle is an ancestor of the inserting block, located at the tip of the blockchain.

Usage

Instances of :Uncle can have the following properties:

PROPERTYTYPEDESCRIPTIONRANGE
From class :Uncle
:uncleBeneficiaryReward owl:DatatypeProperty The reward the beneficiary of an uncle receives if a block includes it. The reward amount depends how far up the Uncle is in the blockchain (the number of the block in which it is included minus the uncle's number). An uncle reward is only paid if the distance is smaller than 8. For a distance of 1 the reward is 7/8 of the block reward, for a distance of 7 the reward is 1/8 of the block reward. xsd:integer
:uncleIndex owl:DatatypeProperty Represents the order of uncles included in a block. xsd:integer
From class :Block
:hasParentBlock owl:AsymmetricProperty Relates a block to its parent in the chain. It always points to the block with a number that is decreased by one, compared to the block it originates from. The relation is asymmetric because if block A is parent to block B then block B can not be parent to block A. It is also irreflexive because a block cannot be parent to itself. :Block
:blockBeneficiaryReward owl:DatatypeProperty The reward the beneficiary receives for mining a block. It is comprised of the base reward (5ETH), rewards for including uncles (1/32 of block reward per uncle) and the fees of the Tx in the block. xsd:integer
:blockCreationTime owl:DatatypeProperty This block's inception date and time. xsd:dateTime
:blockDifficulty owl:DatatypeProperty The difficulty level of this block. xsd:integer
:blockExtraData owl:DatatypeProperty An arbitrary byte array containing data relevant to this block. This must be 32 bytes or fewer. xsd:hexBinary
:blockGasLimit owl:DatatypeProperty A scalar value equal to the current limit of gas expenditure per block. Its purpose is to keep block propagation and processing time low, thereby allowing for a sufficiently decentralized network. Miners have the option to increase or decrease it every block by a certain factor. xsd:integer
:blockGasUsed owl:DatatypeProperty A scalar value equal to the total gas used by all transactions in this block. xsd:integer
:blockHash owl:DatatypeProperty The Keccak 256-bit hash of the block's header, in its entierty. xsd:hexBinary
:blockHeader owl:DatatypeProperty Relates a block to its block header data. The block header data contains 15 pieces of information: 1. the parent hash, 2. the Uncle hash, 3. a beneficiary address, 4. a state root hash, 5. a transactions root hash, 6. a receipts root hash, 7. a log bloom filter, 8. the difficulty value, 9. the block number, 10. the gas limit of the block, 11. the gas used by all transactions in the block, 12. a scalar timestamp in unix time() format, 13. a byte array containing extra data, 14. a mix hash and 15. the block nonce. The property is functional because a block can have only exactly one block header. xsd:hexBinary
:blockLogsBloom owl:DatatypeProperty The bloom filter of log entries resulting from the transactions in the block. The bloom filter helps to identify blocks with logs quickly. To find the indexed log entries from a contract, only the bloom filters of all blocks, which are included in the block header have to be checked. Note that bloom filters can produce false positives but not false negatives. In other words, if the bloom filter indicates that the topic and contract have not produced any logs in a block, this information is final. If the bloom filter indicates a match, it is only a probabilistic result and has to be verified further. The transactions in the block can then be re-executed and the probabilistic match of the bloom filter can be verified. xsd:hexBinary
:blockMixHash owl:DatatypeProperty A 256-bit hash which proves combined with the nonce that a sufficient amount of computation has been carried out on this block. xsd:hexBinary
:blockNonce owl:DatatypeProperty A 64 bit hash which proves combined with the mix-hash that a sufficient amount of computation has been carried out on this block. xsd:hexBinary
:blockSize owl:DatatypeProperty The size of the block header in RLP format in bytes. xsd:integer
:number owl:DatatypeProperty A scalar value equal to the number of ancestor blocks. The genesis block has a number of zero. xsd:integer
:totalBlockDifficulty owl:DatatypeProperty The difficulty of the total chain until this block. xsd:integer
:createsPostBlockState owl:FunctionalProperty Relates a block to the global state of the system after all transactions in the block have been executed. :WorldState
:hasAuthorBeneficiary owl:FunctionalProperty Relates a block to an account to which the fees from gas costs, the static mining reward and the reward for including uncles are transferred. :Account
:hasReceiptsTrie owl:FunctionalProperty Relates a block to the trie that contains the block's receipt data. :ReceiptsTrie
:hasTxTrie owl:FunctionalProperty Relates a block to the trie that contains the data of the transactions contained in the block. :TxTrie
:containsTx owl:InverseFunctionalProperty Relates a block to a transaction included in it. All containsTx relations of a block comprise the block's transaction list. The order of the transactions is determined by their index value. The property is inverse functional because a transaction can only be included in one block. :Tx
:conformsTo owl:ObjectProperty Relates a Block to the protocol variant it conforms to. :ProtocolVariant
:hasBeneficiary owl:ObjectProperty Relates a block to an account to which fees or mining rewards from the successful mining of this block are transferred. :Account
:hasUncleBeneficiary owl:ObjectProperty Relates a block to an account to which the reward for mining an uncle is transferred. :Account
:includesUncle owl:ObjectProperty Relates a block to another block by including it as an uncle. Block B can be an uncle of block A if it is the direct child of the k'th generation ancestor of block B, where 2<=k<=7 but not a direct ancestor of block A. Uncles are blocks found by a miner, when a different miner has already found another block for the corresponding place in the blockchain. They are also known as “stale blocks”. :Uncle
From class :StateTransition
:createsState owl:ObjectProperty Relates a transition to the state it creates. :State
From class owl:Thing
:AccountDataProperty owl:DatatypeProperty Groups all data properties that are specific to an account. owl:Thing
:AccountObjectProperty owl:ObjectProperty Groups all EthOn account object properties owl:Thing
:BlockDataProperty owl:DatatypeProperty Groups all data properties that are specific to a block. These properties are usually functional because a block can only be associated with a single instance of them. owl:Thing
:BlockObjectProperty owl:ObjectProperty Groups all EthOn block object properties owl:Thing
:EthOnAnnotationProperty owl:AnnotationProperty Superclass of all EthOn specific annotation properties. owl:Thing
:EthOnDataProperty owl:DatatypeProperty Groups all data properties specific to EthOn. owl:Thing
:EthOnObjectProperty owl:ObjectProperty Groups all EthOn object properties owl:Thing
:MessageDataProperty owl:DatatypeProperty Groups all EthOn message data properties. owl:Thing
:MessageObjectProperty owl:ObjectProperty Groups all EthOn message object properties. owl:Thing
:NetworkDataProperty owl:DatatypeProperty Groups all EthOn network data properties. owl:Thing
:NetworkObjectProperty owl:ObjectProperty Groups all EthOn network object properties. owl:Thing
:StateDataProperty owl:DatatypeProperty -- owl:Thing
:StateObjectProperty owl:ObjectProperty Groups all EthOn state object properties. owl:Thing
:createsPostMsgState owl:FunctionalProperty Relates a message to the global state of the system after all the message has been executed. owl:Thing
:hasAccountStorage owl:FunctionalProperty Relates an account to the Merkle Patricia tree that encodes its storage contents at a certain account state. This property is Functional because an account state can have only one instance of account storage and inverse functional because an account storage can have only one associated account state. :AccountStorage
:hasTransition owl:ObjectProperty Relates a state to a transition (i.e. a message) that creates a new state. owl:Thing
:partOf owl:ObjectProperty This is a general relation to express part of relationships. The classic study of parts and wholes, mereology, has three axioms: 1. the part-of relation is Transitive - "parts of parts are parts of the whole" - If A is part of B and B is part of C, then A is part of C Reflexive - "Everything is part of itself" - A is part of A Antisymmetric - "Nothing is a part of its parts" - if A is part of B and A != B then B is not part of A. owl:Thing
:simpleDefinition owl:AnnotationProperty This property relates an EthOn class to a definition in Simple English, intended especially for non-technical users. owl:Thing
:suggestedStringRepresentation owl:AnnotationProperty This property relates an EthOn class with a suggested string representation. It can be used to give the term a name, e.g. in program code. owl:Thing
