The ICE center initiative to secure blockchains aims to conduct fundamental research on the key challenges of blockchain platforms and to develop state-of-the-art solutions together with infrastructure providers such as the Ethereum foundation and the Web3 foundation.
To achieve this mission, the ICE center conducts research across all layers of blockchain platforms:
|Enforcing data privacy on public blockchains Learn more|
|Security analysis and correctness certification of smart contracts Learn more|
|Validating the correctness of smart contract compilers Learn more|
|Correctness and security guarantees of next-generation consensus algorithms Learn more|
|Protecting blockchains against network-level attacks Learn more|
Smart contracts on public blockchains leak all of their data, making them unsuitable to handle private data and precluding their adoption in many realistic scenarios. In this project, we develop new languages that can be used to enforce data privacy of smart contracts using cryptographic primitives, such as non-interactive zero knowledge proofs.
Millions worth of USD have been lost due to security issues in smart contracts. In this project, we develop scalable security scanners that can identify security bugs in smart contracts. Further, we build automated verifiers that can certify the correctness of smart contracts with respect to their formal specification.This project is partially funded by the Ethereum foundation.
The correctness of compilers is of crucial importance to the Ethereum ecosystem as smart contracts are typically validated and audited with respect to requirements at the source level. The goal of this project is to develop an automated framework for large-scale, systematic testing and validation of blockchain compilers (such as solc).This project is funded by the Ethereum foundation.
Next-generation consensus algorithms will use new primitives, such as finality gadgets that will allow a separation of block production and the finality of blocks. Ensuring consensus algorithms operate correctly is notoriously difficult, and in this project we tackle this problem.This project is sponsored by the Web3 foundation.
In this project we study the impact that Internet routing attacks (such as BGP hijacks) on the security of blockchain protocols.
