S3: 3 of 3 multisig wallet, controlled by blockchain network, SON network and user, paired with temporary primary wallet controlled by SON network. On deposit, user sends funds to 3 of 3 wallet, funds are staying in 3 of 3 wallet, wallets are periodically rebalanced to match the balance between 3 of 3 wallet and Peerplays pBTC, and funds are moving between 3 of 3 accounts and temporary primary wallet. On withdrawal, user initiates withdrawal process, selects one of three withdrawal scenarios, and once the withdrawal is executed, funds will be moved from temporary primary wallet to 3 of 3 wallet or to another account belonging to the user. There is no clear suggestion on the approach. This is Jonathans proposal.
