Blockchain, by design and definition, defines a item type of database. It is synthetic to read simply in one case database. What that means is, they are designed to be just ever created, and non edited or deleted. That indirectly ways that data stored in blockchain decentralized ledger tin can't be changed (edited or deleted) and will stay there forever making it immutable. You tin can fetch this information dorsum in time to come and can never information technology. And near of the data stored in blockchain decentralized ledger is transactional type data that hardly requires infinite of 1KB or less. Simply what about storing the other form of information such as media files on blockchain ? The number of experts has thought of storing regular information on blockchain decentralized ledger merely they were taken aback when the prices of storing these data on the decentralized ledger tin burn the holes in pockets. Let'south see how much does it toll to store any capricious data on blockchain ?
Concept of gas
Let's consider the Ethereum blockchain every bit it is 1 of the easiest examples to sympathise the bug associated with data storage.
Simply like nodes and miners keeps the bitcoin blockchain live, Gas is the fuel that keeps the Ethereum blockchain functioning. All the transactions such as sending Ether from 1 account to another, creating the smart contract and other activities that require computational ability are charged with fees. The fee schedule is specified in units of gas. Thus any given fragment of programmable computation (this includes creating contracts, making message calls, utilizing and accessing business relationship storage and executing operations on the virtual auto) has a universally agreed toll in terms of gas.1 every transaction has a specific amount of gas associated with information technology and the gas really varies as the complexity of the transaction alters. The higher the complexity of the problem the larger number of gas information technology will cost.
For instance, sending or receiving the Ethereum from ane account to another can costs 21,000 Gas. Every bit nosotros know, smart contracts are the most important characteristic of Ethereum platform and FYI it also toll you the certain number of gas in order to create new contracts. According to Yellow paper, creating smart contract can cost you up to whopping 1,197,977 Gas.
How much does Gas cost ?
Y'all might be wondering nigh the real corporeality of gas fuel which keeps the Ethereum blockchain database alive. The reply may be astounding and very shocking at the same fourth dimension. It will further respond the issues related to the use of blockchain as the database for general files.
Equally per stated in the Yellow paper: ETHEREAL: A SECURE DECENTRALISED GENERALISED TRANSACTION LEDGER,
A gas is worth of 0.00000005 ETH and if yous planning to store data or let's say a 256-chip discussion it will cost you 20,000 gas. A kilobyte is thus 640k gas or 0.032 ETH or sixteen.70 USD as per the current rate of Ethereum which is $528.3 Dollar.
Now calculate the price of storing ane GB of data on blockchain decentralized ledger and blow your mind abroad with an enormous amount that will come upwardly. Equally per the electric current price of Ethereum, 1MB of information will cost you upward approx. 17,100 USD. Calculate the price yous volition need to pay to shop 1GB data of data on the blockchain. Though the facts mentioned above is just truthful for public Ethereum blockchain while the case tin can be totally unlike if we focus on few private or permissioned blockchain. One will, afterward reading the solution, definitely excogitate the idea of using blockchain equally the secured database is far way better than using the traditional database.
The solution
Individual blockchain actually does not crave what chosen the Gas to keep it running in fact, storing the information on permissioned blockchain can be the almost effective manner to keep your data safe and sound without paying hefty of money. The logic here is you lot can shop the data whatever permissioned on private blockchain database such every bit Storj, Sia, Ethereum Swarm etc. which are specially designed convert the blockchain in the most secure database. The information will afterward be published on the public blockchain. Though no 1 will exist able to access it as long as you are holding the private keys. Moreover, you lot tin utilize InterPlanetary File Arrangement or IPFS to admission the data as well as transfer the information from one reckoner to another fashion faster, securely and economically compared to centralized databases vs using the blockchain decentralized ledger.
