English term or phrase: commit to a set of data
A stateless blockchain model replaces on-chain storage with cryptographic commitments. For instance, a user can commit to her smart contract data and then append to her transaction the values that she wants to update with the associated cryptographic proofs. The traditional way ***to commit to a set of data***, taken by Ethereum and other blockchains, is using Merkle Trees. Unfortunately, Merkle Trees are known to have very long proofs. For instance, a user that commits to 1000 values in a smart contract would need to propagate 320 bytes of additional data (cryptographic proof) to change just one of these values. In distributed networks, where every transaction propagates across all nodes, this can eat up a lot of network bandwidth and add substantial costs for nodes participating in the consensus.

To solve these problems, we designed a new commitment scheme — Pointproofs. Pointproofs is a new vector commitment scheme that supports non-interactive aggregation of proofs across multiple commitments. They enable a user to commit to a sequence of values V1, …, V_n, and provably reveal one or many values at specific positions at a later time. Both the commitment and the proof size is only 48-bytes. Moreover, Pointproofs enable any third party to aggregate a collection of proofs with respect to different, independently computed commitments (generated, for instance, by distinct users) into a single proof represented by an elliptic curve point of 48-bytes! Cross-commitments aggregation is a brand new property that none of the previous constructions achieved. Pointproofs also satisfy hiding properties: a commitment and proofs for some values reveal no information about the remaining values.


Ich recherchiere nun schon seit über einer Stunde, finde aber die richtige Formulierung nicht. Kann jemand helfen?

German translation:Festlegung von Datensätzen als Teil des (/ im Rahmen des) Commitment-Verfahrens
Explanation:
Dies bezieht sich auf die erste Phase des Commitment-Verfahrens (die Commit-Phase), in der die Festlegung des Senders auf einen Wert erfolgt, d. h. ein Commitment erzeugt wird.

Die Festlegung von Datensätzen als Teil des Commitment-Verfahrens erfolgt üblicherweise (bei Ethereum und anderen Blockchains) unter Verwendung von Merkle-Bäumen.
