DESCRIPTION:Since the inception of Certificate Transparency\, the use of Tr
 ansparency logs is booming: go sumdb\, Key Transparency\, Sigstore\, etc. 
 These various ecosystems build on top of the promise of transparency logs:
  accurate\, immutable\, publicly verifiable data. Building with tamper-evi
 dent logs means that you can cryptographically prove that the data hasn’
 t been unexpectedly changed.\n\nThis growing number of ecosystems together
  with the increase of the logs’ size called for efficient APIs to ensure
  logs could deliver their promise. This led to the standardization of tran
 sparency logs APIs and format: the concept of tiles and checkpoint emerged
 . Tiles split the underlying Merkle tree into chunks that can be stored\, 
 served and cached efficiently\, while checkpoints represent the state of t
 he tree.\n\nCertificate Transparency (CT) has been the most successful rol
 e model for transparency ecosystems. Static Certificate Transparency API\,
  an evolution of RFC 6962\, is Certificate Transparency’s attempt at imp
 lementing these new standards\, thus bringing all ecosystems closer to one
  another.\n\nThis talk introduces Trillian Tessera\, an open-source Go lib
 rary for building tile-based transparency logs using these standard format
 s on both major cloud and on-premises infrastructure\, together with Tesse
 raCT\, a readily deployable solution for Certificate Transparency using Tr
 illian Tessera.\n\nAttendees will gain insights into a lightweight yet pow
 erful library for building their own reliable and easily maintainable tran
 sparency solutions. We will showcase a concrete example of its application
  with Certificate Transparency. The demo covers the TesseraCT deployment a
 nd the performance of submitting entries and verifying the entry inclusion
  and log consistency.
