If I understand things correctly, Safecoin will be entirely independent of Bitcoin/Mastercoin, and will not depend on the Bitcoin blockchain. MaidSafeCoin, however, depends on Bitcoin’s blockchain, and cannot exist without it (but please correct me if I’m wrong). This is a temporary situation, until MaidSafeCoins can be exchanged for Safecoins.
However, does that make MaidSafeCoins vulnerable for the time being? Could changes to the Bitcoin protocol (although such changes may be unlikely in the near future) be a risk to MaidSafeCoins? Especially if any changes are made to somehow exclude uses of the blockchain by other currencies or functions?
My concerns regarding this issue were furthered when I recently came across an article on Coindesk discussing “bloat” on Bitcoin’s blockchain. [For those who might be interested, the article can be found here: http://www.coindesk.com/new-forms-spam-bloat-bitcoins-block-chain/ ]
Does anyone consider this issue to merit concern?
