Input: entry → new block to write
             network → current state of network
Output: mempool → updated list of pending transactions

Procedure

       mempool ← network.getMempool()
       tx ← NewTransaction(entry)
       tx.status ← 0xFFFF…
       tx.expire ← CURRENT_TIMESTAMP + entry.lifetime
       Broadcast(network.getAllNodes(), tx)

       confirmed ← new List
       confirmations ← 0
       while confirmations <= THRESHOLD do
              if callback then
                    confirmed.add(callback.ID)
                    confirmations ← confirmations + 1

       CS ← Hash(tx.hash + confirmed)
       tx.sign(CS)
       Broadcast(network.getFullNodes(), entry)
       mempool.add(tx)

       return mempool
