Bitcoin Script, SegWit and Taproot
Bitcoin Script specifies spending conditions, such as signatures, multiple signers or time constraints.
Layer 2 rollups explained
A rollup executes activity outside the base layer and publishes information connecting its state to Ethereum.
Oracle and interoperability risks
Evaluate an oracle at the level of its particular feed and deployment.
E-mode, isolation and flash loans
Efficiency mode permits parameter arrangements for defined groups of correlated assets.
Operational controls for digital assets
An operational control should have a defined risk, owner, frequency, evidence and exception process.
Digital asset custody: beyond key storage
Custody combines the authority to move assets with obligations to safeguard and account for them.
MPC wallets and threshold signing
Multi-party computation allows participants to calculate a result jointly without revealing their private inputs to one another.
HSMs and FIPS 140: what validation means
A hardware security module provides a controlled environment for cryptographic operations and key protection.
Crypto settlement and reconciliation
Settlement is the completion of the obligations created by a transaction.
GDPR and blockchain data minimisation
A public address can be personal data when it relates to an identifiable individual.
Ethereum blobs and data availability
Blobs provide a dedicated mechanism for publishing data associated with Ethereum transactions, particularly useful to rollups.
Investigating reconciliation breaks
Reconciliation compares independent views of the same economic position at a defined time.
Incident response and controlled recovery
An alert becomes an incident through investigation, not through its severity label alone.
Provider due diligence and exit planning
A provider assessment should follow the service dependency rather than its product name.
Tokenized securities across their lifecycle
Issuance is only the first event in a security’s life.
MEV and transaction ordering
Maximal extractable value concerns value available through transaction inclusion, exclusion and ordering beyond ordinary block rewards and fees.
Smart wallets and account abstraction
A smart wallet can implement programmable validation and execution rules.
