HASH RATE - ORACLES - BLOCK TIMESTAMP - FORK - CONSENSUS - BITCOIN NETWORK - SIDECHAIN - FIAT CURRENCY - DISTRIBUTED DENIAL OF SERVICE (DDOS) - MARGIN CALL -

in #blockchain6 years ago


HASH RATE each block contains a timestamp in unix. they help to make it more difficult for someone else to manipulate the blockchain.
ORACLES measurement of performance for the mining rig is expressed in hashes per second.
BLOCK TIMESTAMP forks create an alternate version of the blockchain, leaving two blockchains to run simultaneously on different parts of the network. a split in the blockchain where there are temporarily two different blockchains which miners can work on. these can occur if software updates to a bitcoin client are incompatible or if developers decide that changes must be made to the programming of a coin. this deliberate change is called a “hard fork”. it can also be used to describe a separate cryptocurrency which has been split from the main blockchain, such as namecoin being a “fork” of bitcoin.
FORK the decentralized, peer-to- peer network which maintains the blockchain. this is what processes all bitcoin transactions.
CONSENSUS these are theoretical, independent blockchains which are “two way pegged” to the bitcoin blockchain. these can have their own unique features and can have bitcoins sent to and from them
BITCOIN NETWORK consensus is achieved when all participants of the network agree on the validity of the transactions, ensuring that the ledgers are exact copies of each other.
SIDECHAIN the act of calling in a margin requirement. an exchange will issue a margin call when it feels that a trader does not have sufficient funds to cover a leveraged trading position.
FIAT CURRENCY oracles work as a bridge between the real world and the blockchain by providing data to the smart contracts.
DISTRIBUTED DENIAL OF SERVICE (DDOS) a very dangerous threat for cryptocurrency users. often this comes with a severe attack on the network, creating an army of ‘zombie’ computers who simultaneously flood a targeted website or network with requests. this can cause a sustained downtime on said network or even make them crash completely.
MARGIN CALL is any money declared by a government to be to be valid for meeting a financial obligation, like usd, eur or cny
