  The Synchronic Web is a highly scalable notary infrastructure that provides
tamper-evident data provenance for historical web data. In this document, we
describe the applicability of this infrastructure for web archiving across
three envisioned stages of adoption. We codify the core mechanism enabling the
value proposition: a procedure for splitting and merging cryptographic
information fluidly across blockchain-backed ledgers. Finally, we present
preliminary performance results that indicate the feasibility of our approach
for modern web archiving scales.
