it is plausible to expect that AI will shave off a number of bits of security
for both public and symmetric schemes, more in some cases and less in others. Betting on one type of algorithm
against another though is just gambling. Instead: build systems with cryptographic agility
Cryptographic agility enables systems and deployers to transition to safety when cryptographic assumptions may fail due to quantum speedups, AI or human ingenuity
see for instance our prior work in agile cryptogtaphy here eprint.iacr.org/2022/1367 - a starting point. And if you are a cryptography engineer or researcher consider contributing to agility as a sober way of navigating what developments may come. Much more work is needed.
I am looking forward to the great program we have put together for this year's Advances in Financial Technologies. See you in London this October. aft.ifca.ai/aft26
Advances in Financial Technologies AFT 2026 - Accepted papers, conference program and attendance information now public! Looking forward to a great conference this October in London! aft.ifca.ai/aft26/index.html with @AndrewLewisPye, Maria Kyropoulou.

🛡️Online privacy is the condition for digital freedom. That’s why we’re working with Midnight Network to ensure that their protections for private payments and private smart contracts extend to the network level.
🔑Today, we’re excited to announce that NymVPN now accepts payments in ADA @Cardano as a first step.

Theory and Practice of Blockchain Security : read more below about Ouroboros self-healing in the context of the recent Cardano mainnet bug.
The recent mainnet incident was a genuine stress test — and a reminder of why Cardano’s design choices matter. And Ouroboros did exactly what it was designed to do: self-heal.
If you want the deeper story, this blog from @sol3gga breaks it down clearly. Learn more 👇

Funding coming up for exciting research work: submit your proposals to the first call for Cardano Vision projects on selected
topics iohk.io/en/blog/posts/2025/1…
Looking forward to the Fireside tomorrow at #MidnightSummit : Midnight Research Foundations and Future Directions. Tune in
midnightsummit.io/agenda/ to find out how cutting edge research finds its way to real world systems and where research can go from here
if you were involved in any way in the Cardano constitution process or you are active in Cardano governance take some time to participate in this important research at the University of Edinburgh by completing this survey forms.cloud.microsoft/pages/…
our new edinburgh decentralization index dashboard is live blockchainlab.inf.ed.ac.uk/e… featuring the decentralization compass, a way to visualize the decentralization of different blockchains. Soon to be presented by @_LadyChristina_ at SBC 25 live stream youtube.com/playlist?list=PL…
Looking forward to SBC in august 4-7 sbc-conference.com/2025/ if you are in the Berkeley / SF area join to hear about the evolving art of consensus and the edinburgh decentralization index as well as all the exciting talks in this year's program.

Members of the Input | Output research team are looking forward to co-hosting a tutorial during WINE ‘24 at @InfAtEd that aims to provide an overview of game theoretic and economic aspects arising in the design and analysis of #blockchain protocols.
This tutorial, co-hosted by @sol3gga (University of Edinburgh and Input | Output), Elias Koutsoupias (University of Oxford), and Evangelos Markakis (Athens University of Economics & Business and Input | Output), takes place on December 2, 2024 in Edinburgh, Scotland.

we have come to a point where we need to codify our basic rights when we engage with IT systems. This will help create the right incentives for systems to uphold them. Here is a first take, the 11 blockchain tenets iohk.io/en/blog/posts/2024/1…
(1/3) Decentralization can only be measured taking into account multiple different layers of a blockchain system. I am very happy to share that we just released the alpha version of the tokenomics layer of EDI, see
groups.inf.ed.ac.uk/blockcha…
(2/3) The tokenomics layer comes with
a number of clustering tools that are applied to make the results more meaningful. Moreover we will soon add more on chain heuristics that cluster UTXOs from the same wallet together - useful for Bitcoin type ledgers.
