For first four months dero network was running on Monero Helium-Hydra code fork, it is opensource and still on github https://github.com/deroproject/dero
DERO network was running good with opensource Monero code till there was attack on several CryptoNote networks. By that time we had partially written Golang code and few of the nodes were migrated to new dero GOLANG code and those nodes were secure and protected from time-warp attacks and thousands of block were mined in few hours but DERO new Golang code refused to accept those blocks. In hurry we migrated all nodes on Golang code. DERO exchanges were down for long as we didn't have any rpc-interface written in Golang-code due to emergency migration .
Till then we already realized its impossible to stop 51% and double attacks with existing blockchain technology. So we decided and wrote Atlantis with DERO DAG.

For details of attack pls see ,its already on forum https://forum.dero.io/t/bizarre-behavior-of-the-official-pool-statistics/357
Also anyone can go through this ANN thread to refresh memories and details.




Every real CryptoNote devs know each coin generated on CryptoNote protocol is audit-able even after years.



DERO Facts : First blockchain to have: DeroDAG + Cryptonote + Bulletproofs + Complete SSL + POW. Blocktime 12 secs + Confirmation times 2 mins.



Pls feel free to discuss with me something good and technical on discord: https://discord.gg/aQcphjF
