# Cryptocurrency x SGX ## [What the Foreshadow Flaw Means for the Future of Cryptocurrency](https://www.coindesk.com/markets/2018/08/16/what-the-foreshadow-flaw-means-for-the-future-of-cryptocurrency/) [[CoinDesk]] on [[2018-04-15]] ### Notable projects using SGX - [[MobileCoin]] - "Enigma is using it in a unique bid [to boost privacy in smart contracts](https://www.coindesk.com/markets/2018/06/20/enigma-protocol-to-integrate-smart-contracts-tech-with-intel-systems/)" ([[Secret Network]]) - "Ledger [partnered with the tech giant Intel](https://www.coindesk.com/markets/2017/10/24/intel-partners-with-ledger-to-integrate-bitcoin-wallet-software-and-sgx-tech/) to explore using SGX as a new avenue for storing private keys." ### Comments from [[Phil Daian]] - "It is likely that, because many of these systems are slow to upgrade and because many of these fixes require either involved or hardware upgrades, infrastructure will remain vulnerable to this class of attack for a long time" - "It would be surprising if at some point this flavor of attack is not used to steal cryptocurrency." - "In my opinion, good SGX research and systems should assume hardware can always be broken at some cost, and should, as always, design defensively and include layered security" - "SGX will need to be repeatedly tested and broken by adversarial researchers until it can claim a strong degree of security, which will take years," Daian said, going on to add that he believes trusted hardware along the lines of SGX may one day play a big (and positive) role in cryptocurrency. - "Realizing such a technology certainly holds great promise for trust minimization and scalable privacy protection in cryptocurrency and beyond." ### Criticism from [[grubles]] - "Good thing we didn't adopt a certain professor's SGX-based bitcoin scaling solution!"
