Glossary

mShift

mShift is a abbreviation for the Shift mainnet.

tShift

tShift is a abbreviation for the Shift testnet.

dApp (Bapp, Blockchain App, App)

A decentralized application, which is running in a sidechain of Shift. If you add a dApp to Shift, an entry will be made on the blockchain. This will “register” it and makes it visible to everyone.

dApp Store

A universal and decentralized store which lists ALL dApps on the network. (Doesn’t matter if working, not working, offline, online, not complete or completely finished).

BIP39

Is the implementation of a mnemonic code or mnemonic sentence (a group of easy to remember words) for generating deterministic keys. Shift integrates mnemonic checksumming of passphrases to make sure it conforms to the BIP39 standard and that passphrase is used to generate your account.

Block

A block is a group of transactions that were submitted to the network since the last block. Each block (except for genesis block) references one previous block to form the tree called the blockchain.

Block Height

Is the sequential number on the blockchain of a block. Height 0 refers to the genesis block. Current block height refers to the number of the most recent valid block.

Blockchain

A public ledger of all confirmed transactions in a form of a tree of all valid blocks. Unconfirmed transactions are not part of the blockchain. If a node disagrees on which blocks are valid, a fork happens.

Brain wallet

Instead of storing keys in a wallet file, security works via a secret passphrase. Wallets are decentralized and kept on the network. When you create an account, your secret passphrase is used to generate your account on the blockchain. Once your account is generated, you can unlock it and access it by using your passphrase. Shift uses a brain wallet.

Delegate

A Shift account which simply registered to be a delegate on the network (making it a special type of account).

dPoS

This is short for Delegates Proof of Stake. It is the algorithm Shift uses to secure the network. It differentiates from regular PoS (Proof of Stake) as only the top 101 delegates (determined by voting weight of voters) are actively forging and securing the network.

Fork

When a node does not agree on a block, a fork happens and that node create a separate blockchain from the one it disagrees with.

Full client

A client which stays in sync with the mainchain and maintains a full copy of the blockchain. This is also a node or peer on the network.

Genesis Block

The very first block in the blockchain with hard-coded contents.

Hard Fork

Typically referred to as a block when all clients must be updated to a certain version. Clients that are not updated, fork onto a different chain then the ones that are updated because of a change in the core code.

Lite client

A client which connects to a full client on the network and does NOT maintain a copy of the blockchain. It can instantly launch without syncing.

SHIFT

The currency code for Shift.

Node (Peer)

A server/computer/etc. that has installed the Shift full client and is connected to the internet.

Sidechain

A custom blockchain, which is a fully autonomous blockchain secured by its own nodes. Every dApp is one new sidechain.

Standby delegates

All delegate accounts from rank 102 until infinity. These accounts do not actively forge and are only waiting for an opportunity to be in the top 101.

Top (active) delegates

The Shift accounts who are configured on a node to actively secure the mainchain. Only 101 with the most vote weight.

Transaction Fee

The amount that an account pays to have a transaction be included in a block.
