As a layer 3 rollup chain gas fees are extremely cheap
Gas fees on the Digitex blockchain are so cheap that Digitex will subsidize them from house profits, making Digitex the only decentralized casino with zero gas fees on all bet transactions. This opens up decentralized betting to a huge audience of smaller gamblers whose small bet sizes were previously unviable due to high gas fees.
Just as a Layer 2 chain (Arbitrum One) is orders of magnitude cheaper than the Layer 1 chain (Ethereum) on which it settles its transactions, so is a Layer 3 chain (Digitex) orders of magnitude cheaper than the Layer 2 chain (Arbitrum One) on which it settles its transactions.
In simple terms, Arbitrum is a lot cheaper to use than Ethereum, and Digitex is a lot cheaper to use than Arbitrum.
This is because the higher layer chain is only occasionally posting compressed rollups of hundreds or thousands of transactions all rolled up together into a single transaction onto the lower layer chain. These transactions are still readable by software but the gas cost of posting them onto the lower layer chain is shared amongst many transactions, making it much cheaper.
Therefore, the Digitex blockchain can operate as a decentralized chain whose transactions ultimately end up secured by the Ethereum blockchain, and yet the average gas cost of a transaction on Digitex is only a fraction of a cent. In current tests the gas costs of posting Digitex's rollups onto the Arbitrum blockchain are roughly $0.31 to post about 1,400 compressed transactions onto the Arbitrum One chain. This works out at roughly one fiftieth of a cent per transaction ($0.0002).
This cost can and will fluctuate according to the amount of data included in the transaction. More data means fewer transactions can be posted in a single rollup transaction, meaning that the $0.31 in gas fees to post a rollup transaction must be shared amongst fewer transactions which makes the cost per tx higher.
For example, a simple token transfer uses much less blockspace than a transaction to a betting game smart contract or to the house bankroll smart contract. But the most expensive smart contract transactions on Digitex are currently testing at one fifth of a cent ($0.002) which is still extremely cheap.
These ultra-low gas costs make it possible for Digitex to break the mould with decentralized casinos and offer all players zero transaction costs when sending bets to our game smart contracts. Gas fees that are payable in a different token than the one you are sending are just about the most unintuitive and confusing user experience you can imagine for new crypto users.
Digitex aims to completely abstract gas fees out of the decentralized betting user experience. Our Layer 3 chain's ultra low gas fees make it possible for us to do this by subsidizing them from house profits.
This means that Digitex is open to all bet size gamblers, not just the high rollers who can afford to spend up to $0.70 in gas fees to place a single bet, like it costs on zkasino or JustBet. With such high gas costs that come about from placing bets directly onto Arbitrum or Polygon as those decentralized casinos do, its impossible for small players to join in.
Even if you're placing $10 bets, $0.70 in gas fees just to place your bet is an extra 7% house edge working against you on top of the actual house edge, making it literally impossible to win. And there's no point even thinking about placing $1 bets.
Digitex will welcome hundreds of thousands of smaller players for whom the decentralized betting experience has been off-limits until now. And with our own dedicated chain to handle their traffic there won't be the usual chain congestion and gas price spikes that mainstream chains suffer from in busy times.
