I'm not sure if I understand the way how ARK tries to combat centralization risks.
Here's a quote from their
article on Medium:
User Kevin has 20 million tokens. Kevin can nominate his delegate fairly easily. He may even be able to vote in 2 of his own delegates, but rightfully so, he purchased 20 Million tokens. What he cant do is be guaranteed to nominate more than 8 delegates before his weight is too diluted to maintain his position.
What makes Kevin's weight diluted before he can nominate the next 8 delegates? Can't he just create several accounts and spread his 20 million tokens between them?
I didn't find any clues on that in ARK's
whitepaper, just this:
The 51 forging nodes with the highest number of votes are eligible to Forge ARK
blocks. This design eliminates the possibility that any single large ARK holder or
an organization holding large percentages of ARK are able to gain control over
the entire network by voting for all of their nodes into forging positions, thus
effectively taking complete control over that DPoS Blockchain. Votes from ARK
Tokens held by ARK Crew may be used at ARK Crew's discretion.
