How do I store an image in ethereum blockchain?
If you want to upload a PDF, Word, or image file to IPFS.

- You inform IPFS to add this file, which generates a hash of the file. Note an IPFS hash always starts with “Qm….”
- Your file is available on the IPFS network.
Can you store files on a blockchain?
The intelligent way of storing data is to store the hash of the data in the blockchain. Hash is a generated string, by providing our data as input. The hash of the data is comparatively minimal; thus, the cost is low. The raw data can be stored using a file system as well.
What can be stored on blockchain?
As we now know, blocks on Bitcoin’s blockchain store data about monetary transactions. Today, there are more than 10,000 other cryptocurrency systems running on blockchain. But it turns out that blockchain is actually a reliable way of storing data about other types of transactions as well.

Is blockchain stored in flat file?
A Blockchain is not a general-purpose database. Conceptually it is a flat file that holds a linear list of simple transaction records. As the list is “append only”, entries are never deleted from the flat file, rather the file keeps on growing indefinitely and gets replicated in every node in the peer-to-peer network.
How much data can I store on blockchain?
This means that they have to download the whole 250 GB of blockchain data containing the block headers and transactions. More so, the current bitcoin blockchain size limit is 1 MB. However, some of the space within this limit is not usable. So, you will have to work with the bitcoin blockchain size limit just as it is.
What is nonce in blockchain?
A nonce is an abbreviation for “number only used once,” which is a number added to a hashed—or encrypted—block in a blockchain that, when rehashed, meets the difficulty level restrictions. The nonce is the number that blockchain miners are solving for, in order to receive cryptocurrency.
What is Ethereum whisper?
Whisper is a part of the Ethereum P2P protocol suite that allows for messaging between users via the same network that the blockchain runs on. There are many uses, some of which are listed on the wiki. The protocol is seperate from the blockchain, so smart contracts do not have access.
