Splinterlands recently announced the following in regards to the Validator Nodes:
While the presale will require 500 vouchers for each license purchase in addition to the $1,000 of SPS cost, the subsequent phases will not require vouchers but instead allow vouchers to be used to receive up to a 50% discount on the price. For example, in Tranche 1 the voucher discount rate is $3.00, which means that each voucher token spent will reduce the price by $3.00. Since the maximum discount is 50%, that means that you can spend up to 500 vouchers to reduce the price from $3,000 to $1,500. This allows voucher tokens to always have value when it comes to buying licenses, while also not making them required.
So, in relation to Tranche 1 the value of the Voucher "can not" exceed the cap $3 (of course vouchers have other uses and I have no idea what it's price will be).
On the other hand though, the value of the voucher should get closer to $3 someone else might think which is quite an increase based on today's price.
Thanks for reading!
