Pooled transactions

[blacksmithtm]

Hello,

Do you think pooled transactions are a possibilty? For example a wallet with superior reputation for being secure, reliable, honest, and having a significant user base... Wallet making a partnership with say coinbase and bitpay, and when users, using the webwallet, bitpay/coinbase will get an IOU instead of bitcoin, avoiding a miner fee for each tx individually. At the end of the day or week the entire ordeal could be settled in one large blockchain transactions possibly saving several BTC's in miner fees overall. If this becomes a thing, how would this affect mining in the future, when block rewards start disappearing?

with my limited knowledge, I think that's kind of where we're headed.  With mainstream adoption and transactions per second increasing 1000x and more, everyone will be competing for space on each block.  If the protocol remains as-is then miner's fees will go way up with demand, and then that's when online web wallets (paypal) would come in allowing user-to-user internal transactions for "lower" fees (that they keep) off the blockchain
