Happy to be part of Algorand community. When I started looking into Algorand one thing that caught my eyes is “note” field. There are many protocols exists on the bitcoin blockchain such as omni protocol. Which uses “op_return” code (40 to 80 byte) field to run custom tokens and other functionality. But bitcoin has a lot of inherent issue related to using this field. High transaction fees, longer confirmation time and smaller field size. All these issues are already solved with Algorand with whooping 1 kb notes field size.
Armed with SDKs, we set out to build a simple solution that is useful for anyone to capture and store data forever. We also looked at what are some of the use cases. To our surprise we found many. Even in today’s digital world, almost half of all signatures are paper based. We paper sign everywhere. Credit card transactions, work orders, contracts, IOUs, cheques and legal documents. The businesses required to store these documents at least for few years. These data often end up in cloud storage services and pay monthly service fee.
On top of this, data in the internet can be deleted by the owner or service providers. Tweets can be deleted, reviews can be altered or hidden, Powerful elites scrub and erase all their past.
What if we capture all those data, interactions, signatures and store it on-chain transaction? of-course, there are some challenges with it. Users will have to get some Alogs, maintain a wallet, and then use it. To make it simple and easier, we created a user interface to hide all complexities. Anyone can sign-up and save text to Algorand blockchain in couple of clicks. Since the transaction fee is very very low for now, we hide the wallets from end users.
Users use their email address to signup and login. The initial credit is good for first 100 transactions. beyond that they can top up the credit with PayPal transaction.
It is always better to see it in action to believe it. Go ahead, sign up at https://proofplum.com . Once signed in, click on “My Text” on the menu. Click new and type your text. Click the plain text checkbox and click save. In few seconds, refresh to see the committed transaction details and the “note” field.
Any feedback both positive and negative is much appreciated.
