What Was zkSummit9 2023?
zkSummit9 2023 was the ninth edition of zkSummit, a specialist conference on zero-knowledge (ZK) cryptography, held in Lisbon, Portugal, on 4 April 2023. It gathered cryptographers, researchers, and builders to dig into ZK proofs, the advanced math powering privacy and scaling in Web3, through deep technical talks and discussion. The official page sat on the zkSummit site. As a highly technical, single-topic summit, it drew a specialist crowd.
Zero-knowledge tech is one of crypto's most important frontiers, which gives zkSummit real depth. To follow similar events, check the crypto events calendar and our Web3 tech events list.
Key Themes at zkSummit
The agenda matched a cryptography crowd:
- ZK proofs and applications.
- Privacy and confidential systems.
- ZK rollups and scaling.
- Research and new constructions.
The deep technical focus set it apart. Many guests also tracked broader blockchain events through CoinGabbar.
How Crypto Is Growing in Portugal
Portugal has long had a reputation as one of Europe's most crypto-friendly countries, and Lisbon has become a magnet for Web3 builders and researchers. As an EU member, Portugal operates under the bloc's MiCA framework, with the Bank of Portugal registering crypto firms for anti-money-laundering purposes. Crypto is legal to own and trade, though not legal tender.
On tax, Portugal once famously did not tax personal crypto gains at all. That shifted with the 2023 budget, gains on assets held under a year are now taxed, while assets held over a year can still be tax-free for individuals, a regime still attractive by European standards. Beyond tax, Lisbon's draw is its community: a dense cluster of crypto founders, researchers, and events that makes it a natural home for specialist gatherings. For a deep cryptography summit like zkSummit, that concentration of technical talent is a real advantage. For more shows, see CoinGabbar's crypto conferences page.
Impact of the Event on ZK Technology
A ZK summit in Lisbon helps the field in real ways. It advances zero-knowledge research. It connects cryptographers with builders. And it pushes privacy and scaling forward. Each edition deepens the ZK ecosystem.
Why Sponsors, Exhibitors and Projects Should Join
A specialist ZK summit reaches the field's best minds. Strong fits include:
- ZK rollup teams: recruit cryptographers.
- Privacy projects: find researchers.
- Proving and infra firms: reach builders.
- Research labs: share new work.
- Funds and grants: spot deep-tech teams.
