There is not much publicly available information about the practical
security of the Hyperledger Fabric blockchain. However, the framework has been
actively used for quite some time in various fields including digital financial
assets.
Using the concept of a vulnerable smart contract that imitates a digital
financial asset, the speaker will examine the nature of the transaction
time manipulation attack and its financial consequences. Igor will present his
open‑source solution to defend against such an attack. The solution is based
on NTP/NTS client and is resistant to man-in-the-middle attack. Hyperledger
Fabric smart contract developers can use the solution instead of implementing time
manipulation protection on their own
