The story
A technical curriculum built around three networks
A43 prepared a programme spanning Ethereum, Polkadot and Cosmos, allowing participants to compare validator duties, penalty conditions, operating models and real-world failure cases.
The first day addressed consensus and staking mechanics, historical slashing events and the kinds of organisations operating validators. It also examined how established frameworks such as ISO 27001 and SOC 2 relate to staking infrastructure.
The goal was to give participants the right technical language and context before assessing specific operators.
Getting inside validator architecture
The second day moved into software, infrastructure and day-to-day operations. Topics included client software, signing keys, remote signing, key security, configuration management, testing, monitoring, recovery and the security implications of hosting and technology suppliers.
Practitioner discussions brought infrastructure and client-implementation perspectives into the workshop, including participants associated with Teku/ConsenSys and Dextrac.
The exercises examined risks that are easy to misclassify when looking only at a protocol's penalty schedule, such as an unsafe failover, a key accidentally active on multiple machines, or changes deployed without sufficient testing.
Turning technical understanding into assessment questions
The third day extended the discussion with additional practitioner participation, operator processes and assessment design.
A43's source package includes a draft 21-question operator assessment grouped under seven areas: operator characteristics, security governance, infrastructure, applications, slashing prevention, operating processes and key management.
The material was supported by technical decks, fact sheets, a historical slashing dataset, security-control references and interactive participant exercises.
The source records show practical engagement: one operations-focused exercise collected 34 questions about dependencies, keys, testing and incident handling; a final-day red-flag exercise recorded 14 responses from six participants. These are exercise results, not a verified total attendance figure.
A concrete research and training deliverable
The engagement produced more than an introductory presentation. It combined network-specific research, practitioner exchanges and a draft instrument for evaluating operational risk.
The available record does not establish that Munich Re adopted the draft questionnaire as a final underwriting standard or issued a policy as a direct result. The completed assignment was the technical programme and its assessment material.
