Indeed, TAU dev is young in blockchain, and we are making many mistakes. Thanks for the community still staying with us. So two actions are adopted. One, learning every day to increase our capability. 2nd, open up TAU development to community members via “developer bounty”, that is to using TAUcoins as compensation to incentivate talented programmers to help. We will annouce the bounty very soon.
Regarding how hard to perform 51% attack. For seeking financial benefits, 51% attack to the chain is not much profitable. But for destroying the chain, 51% attack is well justified for high investment, when super power want to do that. Therefore “double spend” is not primary conern, since it is seeking profit and checkpoint technology can deal with double spending. At the same logic, this is why “allow rebellion feature” is important. Assume one day, tau community found many transactions are censorshiped due to unknow power 51% attack. The epochs design will provide a chance for us to declear rebellion when major mining power is contained by previous epoch.
For keep club leader honest, i think there shall be a “yelp” service to rank their behavior. I would rather let club leader have full freedom to take all block reward, then club members just leave it alone.
Our mining energy cost is much lower than POW, and at same scale as POS. For the speed, reducing hand over frequency is way to increase TPS when lots of transactions in pool.
I think a developer so composed to detect a bug from the blockchain can easily sustain an attack to the network.
Based on the Proof Of Transaction which prioritize the transactions processed in the network increases rewards for the miners and club mining group will likely tells us that blockchains with a lot of active harvest power become relatively hard to compromise since the system isn't favor miners through expensive way of generating or mining a block but through system of transactions acquired.
However, smaller blockchains with a common protocol such as POW system, may be much more vulnerable to such attacks considering there is way less computational power to compete with for the attacker. But POT build on a different purpose compared to POW but there still at chance that Taucoin can still be penetrated at such time. What are the preventive measures the team can offer or at what protection levels the team can handle such incident?
