Hash chained storage
WebAug 24, 2013 · The simplest representation of a hash table is an array (the table). A hash function generates a number between 0 and the size of the array. That number is the index for the item. There is more to it than this, bit that's the general concept and explains why lookups are so fast. WebDec 31, 2024 · We present XCLAIM: the first generic framework for achieving trustless and efficient cross-chain exchanges using cryptocurrency-backed assets (CbAs). XCLAIM offers protocols for issuing, transferring, swapping and redeeming CbAs securely in a non-interactive manner on existing blockchains.
Hash chained storage
Did you know?
A hash chain is the successive application of a cryptographic hash function to a piece of data. In computer security, a hash chain is a method to produce many one-time keys from a single key or password. For non-repudiation a hash function can be applied successively to additional pieces of data in order to … See more A hash chain is a successive application of a cryptographic hash function $${\displaystyle h}$$ to a string $${\displaystyle x}$$. For example, See more Winternitz chains (also known as function chains ) are used in hash-based cryptography.
