Patricia tree (or trie)
| Глоссарий по криптовалютам и блокчейну |
A data structure which stores the state of every account. the trie is built by starting from each individual node, then splitting the nodes into groups of up to 16 and hashing each group, then making hashes of hashes and so forth until there is one final "root hash" for the entire trie. the trie has the important properties that (1) there is exactly one possible trie and therefore one possible root hash for each set of data, (2) it is very easy to update, add or remove nodes in the trie and generate the new root hash, (3) there is no way to modify any part of the tree without changing the root hash, so if the root hash is included in a signed document or a valid block the signature or proof of work secures the entire tree, and (4) one can provide just the "branch" of a tree going down to a particular node as cryptographic proof that that node is indeed in the tree with that exact content. patricia trees are also used to store the internal storage of accounts as well as transactions and ommers. see here for a more detailed description.

Uniquely attributable fault, английский
A fault such that there exists clear evidence which can be used to determine exactly which validator committed the fault. for example, liveness faults are not uniquely attributable because if a message from a fails to reach b, it could be because a failed to send that message, or because b failed to listen to it, whereas equivocation faults are uniquely attributable.
Slashing condition, английский
A condition which, if triggered by a validator, causes the validator`s deposit to be destroyed.
