The calculation of trust in peer-to-peer communication requires a value called interaction trust value. According to one of the survey papers that i referred, it stated that the high value of this interaction trust causes most of the peers to come under the trusted peers. I was thinking that if the value of this trust value is lowered ..may be a better chance would come up. So i wanted to know about it. following is that concerned survey paper. Good Day!
Please CMIIW. Did you mean to say that you'd like new peers to have higher chance of gaining trust from existing peers?
If that is the case, sure it is possible. However, you need to consider the risks. For example, malicious peers can leave the network and rejoin as new peers.
