Orphan blocks (purple) exist outside of the main chain. A blockchain is a decentralized, distributed, and often public, digital ledger consisting of records called blocks that are used to record transactions across many computers so that any involved block cannot be altered retroactively, without the alteration of all subsequent blocks.
A diagram of a bitcoin transfer. The bitcoin protocol is the set of rules that govern the functioning of bitcoin.Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all bitcoin transactions; mining and proof of work, the process to create new bitcoins and verify transactions; and ...
Polkadot is a decentralized, nominated proof-of-stake blockchain with smart contract functionality. The cryptocurrency native to the blockchain is the DOT. It is designed to allow blockchains to exchange messages and perform transactions with each other without a trusted third-party.

If the network is unable to reach consensus over the next step (or block), within a certain time, the protocol enters in a recovery mode, suspending the block production to prevent forks (contrary to what would happen in blockchains based on the "longest-chain principle", such as Bitcoin). The Algorand team claims the recovery mode of the ...
