v2.1.5

Overview

This is a minor release which contains an important bug fix. The computed challenge for verify_cell_kzg_proof_batch did not take into account all deduplicated commitments, resulting in a potential Weak Fiat-Shamir vulnerability. See #607 for more details.

What's Changed

• Fix rust CI checks by @jtraglia in #608
• Create cell verification challenge with deduplicated commitments by @jtraglia in #607
• Bump versions to v2.1.5 by @jtraglia in #609

Full Changelog: v2.1.4...v2.1.5

v2.1.4

Overview

Some Ethereum clients have (rightfully) expressed concerns with using an unreleased version of blst. To address these concerns, we reverted blst to its latest stable version and added back point-at-infinity filtering in c-kzg-4844.

What's Changed

• Add back point-at-infinity filtering in g1_lincomb_fast by @jtraglia in #603
• Revert blst to v0.3.15 by @jtraglia in #604
• Document g1_lincomb_fast when called as msm([]) by @asn-d6 in #606
• Bump version to v2.1.4 by @jtraglia in #605

Full Changelog: v2.1.3...v2.1.4

v2.1.3

Overview

This is a minor release that fixes a bug which could cause verify_cell_kzg_proof_batch results to be incorrect. In the previous release we simplified g1_lincomb_fast by removing point-at-infinity filtering because blst added this filtering. Unfortunately, there was a path in which the filtering did not happen. We have updated blst to the latest commit which includes a fix for this.

What's Changed

• Bump the actions group with 5 updates by @dependabot[bot] in #597
• Add new zkSecurity audit report by @jtraglia in #599
• Update blst to fix point-at-infinity issue in g1_lincomb_fast by @jtraglia in #600
• Remove tunable threshold in g1_lincomb_fast by @jtraglia in #601
• Bump version to v2.1.3 by @jtraglia in #602

Full Changelog: v2.1.2...v2.1.3

v2.0.0

This is a major release which adds support for EIP-7594 (PeerDAS).

Notable changes:

• The codebase implements and exposes all public methods of the EIP-7594 cryptography specification.
• The trusted setup format has been updated to include G1 points in monomial form.
  • This version of c-kzg-4844 requires the new trusted setup file.
  • The new trusted setup file can be used with previous versions of c-kzg-4844.
  • Download the new file from trusted_setup.txt in this repository.
  • This should match trusted_setup_4096.json in the specifications.
• A new precompute parameter has been added to functions which load the trusted setup.
  • This configuration option is used to optimize FK20 proof computations.
  • Higher values will compute FK20 proofs faster but use more memory.
  • Compared to precompute=0, precompute=8 is ~75% faster but uses 96 MiB of memory.
• In the Nim bindings, the "zero overhead aliases" have been removed.
  • There is only a single set of API functions exposed now.
• In the Rust bindings, the API functions have been moved to the KzgSettings structure.
  • For example, here is the before and after for blob_to_kzg_commitment:
    • KZGCommitment::blob_to_kzg_commitment(&blob, &kzg_settings)
    • kzg_settings.blob_to_kzg_commitment(&blob)
