 Nowadays, a digital signature is more or less the authenticator and validator of a transaction. Taking the legal contract example a step further, a digital signature is _stronger_ than the old way of a legally binding agreement. It guarantees that nothing can change once a contract (in this case, your transaction) is signed. The signature in your transaction proves that you hold the [**private key**](/identity.rs/specs/iota_did_method_spec/#private-key-management) that controls the funds. And the transfer being made is held under a derived account, like a sub-account in your bank account.
 
-IOTA decided to use the [**Ed25519**](https://en.wikipedia.org/wiki/Curve25519) signature scheme, based on the popular [**EdDSA**](https://en.wikipedia.org/wiki/EdDSA) scheme. Using both of these schemes in collaboration makes the signature reusable! The Ed25519 can verify single signatures and batches of transactions very quickly which means those two IOTA users in different parts of the world can stagger big and small transactions between or with others _at the same time_ if they want. They can even do this with little delay in sending and receiving. And their transactions are even _more_ secure as this signature generates keys faster. In this case, that means a whole brand new, complex string of numbers and letters is created specifically for each of their transactions as security.

 ## Addresses
 
 Speaking of reusability, complex strings, and keys, there are [**addresses**](/chrysalis-docs/guides/developer/#iota-15-address-anatomy) which we talked about briefly before. Again, addresses in this case are like a personal account, something viewable and sendable to people you want to do business with. They are also linked closely to the digital signature as a [**keypair**](https://en.wikipedia.org/wiki/Public-key_cryptography) but that’s a concept for another time!
 
 This personal account belongs to a seed. In the world of cryptography, a seed refers to a “private key”. Simply put, you have the seed (your private key) keeping your address (your account) safe. In fact, [**the seed** **generates** **the address**](/chrysalis-docs/guides/developer#addresskey-space)! For now, we’ll keep out of the more technical concepts and explain what addresses can do inside IOTA.
 
-Within IOTA, our [**new reusable addresses are “human readable**”](/chrysalis-docs/guides/dev_guide/#seed-and-addresses), meaning that addresses are entirely lower case, rather than mixed case. In this way, you will have an easier time sharing the address and typing one in. There is a lot to break down here but it’s not too difficult to grasp! Those old codemakers may have come up with coded messages that used upper and lowercase letters to make the messages even more complex. This would have been good for security but a pain to write, share, and receive amongst themselves.

 IOTA’s addresses are none of those things which makes it easy on you and the people you share transactions with to send and receive tokens! And to make things even simpler, addresses are always 64 characters long, start with the prefix iota1(to distinguish IOTA addresses from other similar looking addresses of other cryptocurrencies),and contain a checksum (an automated function that verifies a word has the expected number of letters) to prevent accidental typos.

 But as software wallets are part of your operating system, the security of a software wallet can always be only as good as the security of the entire operating system. So you need to make sure that your operating system is free of malicious software, otherwise it will be easy for an attacker to get access your secret keys and your tokens. If you use a software wallet to handle your IOTA tokens, always have an up-to-date system, run quality antivirus and anti-malware programs, and follow best practices for cybersecurity.
