Systems and methods for writing updates to and/or reading previously stored updates of assets implemented as smart contracts on a decentralized database

A method of reading previously stored assets that are implemented using smart contracts on a decentralized database, wherein the assets include an individual asset that has a state, wherein at least part of some of the assets is stored on a content-addressable file system, the method comprising:

• receiving a read request, from the first client computing device associated with a user, to read information of the individual asset;
• transferring the read request to the decentralized database;
• subsequent to receiving the read request, receiving a first reference from the decentralized database, wherein the first reference refers to a first file on the content-addressable file system;
• obtaining the first file from the content-addressable file system, based on the first reference;
• extracting a previous-file reference from the first file;
• responsive to the previous-file reference referring to a second file on the content-addressable file system, obtaining the second file, and extracting a second previous-file reference from the second file;
• repeatedly obtaining additional files and extracting previous-file references from the additional files until an individual previous-file reference from an individual file no longer refers to another file on the content-addressable file system;
• and
• presenting information from the first file, the second file, and the additional files through a user interface to the user.

A method of modifying assets that are implemented using smart contracts on a decentralized database, wherein the assets include an individual asset that has a state, wherein at least part of some of the assets is stored on a content-addressable file system, the method comprising:

• receiving a write request, from a first client computing device associated with a user, to modify the individual asset;
• transferring information based on the write request to the decentralized database, wherein a first part of the state of the individual asset is stored on the decentralized database and a second part of the state of the individual asset is stored on the content-addressable file system;
• subsequent to receiving the write request, receiving, from the decentralized database, a first reference to a first file, wherein the first reference is included in the state of the individual asset, wherein the first reference refers to the first file, wherein the first file is accessible through the content-addressable file system, wherein information included in the first file is included in the second part of the state of the individual asset, wherein the first reference includes a hash value that is generated by hashing some or all of the first file;
• generating a second file and a second reference, wherein contents of the second file is based on the write request, and wherein the contents of the second file includes the first reference to the first file, wherein the second reference refers to the second file on the content-addressable file system;
• storing the second file on the content-addressable file system, wherein storage is based on the second reference;
• and
• recording the second reference in the first part of the state of the individual asset on the decentralized database.
