As a blockchain enthusiast, I've been waiting for a solution like this for a while. I wouldn't consider it as a replacement for a GDrive as its purpose is different. These are the features I bought Tier 2 for: 1. client portal for uploading client files in a secure way, 2. ability to send files securely to third parties without them having an account with TransferChain and limiting the number of downloads. 3. history of all files access records which is great for professionals in consulting and legal fields. 4. encrypted chat (probably similar to XMTP-like messaging) between team members and clients with TransferChain accounts (they offer a 5GB free account on their website). 5. All records visible on their blockchain explorer. The number and field size limitations may not work for everybody, but to me Tier 2 is well-worth the money just for the features above. The closest comparison to the product (and with less features) is probably Sync, but downloads there are very slow. Kudos to the team and looking forward to your product success.
