 ## Abstract
 
-Ethereum uses a [Merkle Tree](https://github.com/ethereum/wiki/wiki/Patricia-Tree) to store the state of accounts and their storage. This allows verification of each value by simply creating a Merkle Proof. But currently, the standard RPC-Interface does not give you access to these proofs. This EIP suggests an additional RPC-Method, which creates Merkle Proofs for Accounts and Storage Values. 
+Ethereum uses a [Merkle Tree](https://ethereum.org/en/developers/docs/data-structures-and-encoding/patricia-merkle-trie/) to store the state of accounts and their storage. This allows verification of each value by simply creating a Merkle Proof. But currently, the standard RPC-Interface does not give you access to these proofs. This EIP suggests an additional RPC-Method, which creates Merkle Proofs for Accounts and Storage Values. 
 
 Combined with a stateRoot (from the blockheader) it enables offline verification of any account or storage-value. This allows especially IOT-Devices or even mobile apps which are not able to run a light client to verify responses from an untrusted source only given a trusted blockhash.
