Seeds should not saved on the blockchain. Somewhat seeds are used to generate personal keys, that are then used to create digital signatures, which function proof that the proprietor of it agrees to the transaction.
Bitcoin transactions create transaction outputs that include the worth in Bitcoin assigned to them, in addition to the situations required to spend that output as an enter to a different transaction. The proprietor of that output, and due to this fact the Bitcoin worth related to it, is the individuals who can fulfill the situations specified within the output. The most typical situation is that of a digital signature – the output specifies a public key (or its hash) and so the situation is that the spending enter should include a digital signature created by the personal key comparable to the required public key.
As their identify suggests, public keys are supposed to be public and could be shared publicly with out publicity of the personal key. The personal key, because the identify suggests, should be stored personal. It’s then used to generate the signature. The maths works out such that it isn’t potential to compute the personal key for a public key, neither is it potential to create a signature for that public key with out additionally having the personal key.
A seed is solely one other personal key, as it’s used to generate different personal keys. Though seeds should not sometimes used straight as personal keys for producing signatures.
Lastly, Bitcoin doesn’t require any kind of registration of public keys when their personal keys are generated. The area of potential personal keys is so giant that it’s mainly unimaginable for 2 folks to generate the identical personal key if they’re producing their keys appropriately. Nonetheless, provided that possession is mainly outlined as the power to spend an output, if personal keys are improperly generated, or an output has insecure spending situations, a number of folks might “personal” the output and be capable of spend it independently of one another.
