| Summary | 0003795: NSE should change proof-of-work hash algorithm. | ||||
| Description | Given the widespread adoption of lite- and dogecoin scrypt ASIC miners, it would be trivial to forge nse PoW. At 22 bits even a discarded junk-miner could generate several PoW per second. | ||||
| Additional Information | Possible replacements could be: - X11 cpu-only hash https://www.dashpay.io/x11/ - Our own set of hashes/crypto, to avoid those used by coins at all, since sooner or later ASICs will appear for them. Naive example: H = sha256(aes_twofish(kdf(scrypt(nonce)), nonce)) | ||||
| Tags | No tags attached. | ||||

Implemented as of ea544ab2c..f536489f8, but to be toggled via #define to activate new code. |

Is this also relevant for GNS revocation POW? |
|
|
Yes, and I fixed it in a subsequent patch there as well. |
