Blockstack PBC announced on Jan. 29 the completion of its “Milestone II” that unlocked $6.eight million from its 2017 preliminary coin providing. The undertaking claims to have on-boarded a million verified customers, an achievement that some locally didn’t consider. Cointelegraph carried out an evaluation of blockchain information to see if this declare could possibly be confirmed.
The significance of the milestone
The Blockstack preliminary coin providing (ICO) was conducted in November 2017 by means of the CoinList platform. It was notable for being “SEC-qualified,” which means that it had stronger reporting obligations to the regulators and implied that it was not in danger from getting prosecuted by the Securities and Exchange Commission. It was provided to each accredited and retail traders.
The providing was additionally structured in result-based milestones that might unlock parts of the collected funds. There have been two of those milestones, with the primary one requiring the profitable launch of the community’s mainnet by January 2019. To unlock the second milestone, the undertaking needed to attain a million verified customers, a outcome that might be checked by an ostensibly impartial advisory board.
Notably, Blockstack pledged to return to the traders 80% of the funds locked by every milestone if it did not ship.
Blockstack’s core worth proposition is to offer a verifiable identification secured by blockchain, which will be utilized by permitted entities. This is getting used to create an ecosystem of apps which can be authenticated with Blockstack ID.
It stands to purpose that given this technique, the presence of 1 million verified customers could possibly be conceivably verified by analyzing Blockstack’s blockchain information. The definition utilized by the advisory board consists of all doable manners of verification, together with by way of social media accounts or government-issued ID. These needs to be seen on the platform’s API.

While Blockstack makes use of Bitcoin’s OP_RETURN operation to retailer information on the blockchain, it’s not instantly readable. Blockstack offers its personal Bitcoin explorer that features detailed info on all of the usernames saved on the blockchain.
We used penetration testing instruments to crawl by means of your entire historical past of Bitcoin blocks till May 25, 2018 — the date of the primary operation recorded on Blockstack’s pockets used for assigning names. We filtered by means of solely the blocks that the API reported as having “name operations,” which netted a listing of 17,000 blocks.
This checklist was fed into one other crawler that extracted 1.5 Gigabytes value of block information, which crucially included particulars on all identify operations.
We filtered this checklist to solely embrace usernames, with none extra information comparable to time of creation.
The blockchain recorded a complete of 1,997,949 names, although this determine additionally consists of duplicates from prime stage domains (about 15,000).
Seeking to totally verify whether or not the customers are verified, we got down to subject API requests for every person discovered by means of this methodology. However, the sheer time required to make 1.9 million requests, along with eventual server restrictions, meant that we needed to restrict ourselves to a pattern of simply 50,000 customers.
While the analysis seems to a minimum of verify the person rely reported on Blockstack’s explorer homepage, a deeper look reveals some peculiar traits to the usernames.
Specifically, many usernames have both an “fc-” or “bc-” prefix on them.
A peek into a few of the usernames on Blockstack. The checklist is ordered chronologically, not alphabetically.
In reality, there are 1,316,894 “fc-” names and 325,356 names with “bc-” in them. Searching for these names within the block explorer yields a “no results” web page — which is distinctly completely different than querying for a person that really doesn’t exist.
Given these findings, it seems that solely about 400,000 of Blockstack customers are literally verifiable ultimately by means of the platform. The API does return legitimate information for each “fc-” and “bc-” names, however after greater than 2,000 probe requests the software program didn’t present verification particulars for a single considered one of these customers — which led us to interrupt the search.
Out of the 50,885 customers we sampled from the remaining 400,000, solely 1,565 had any point out of a verification. This is a fee of roughly 3% verified customers.
In a July 2019 filing with the SEC, Blockstack revealed its personal figures:
“Of those 115,780 accounts, approximately 16,100 accounts had provided a “social proof” as proof of getting a human person, comparable to a GitHub hyperlink or Twitter message hyperlink.”
The determine of verified accounts quantities to 14% of Blockstack customers. This would nonetheless be properly in need of the required 50% dictated by its whole person rely.
Are the bizarre names the reply?
Blockstack used a number of initiatives to onboard customers towards the tip of 2019. One of those is the Blockchain.com airdrop, enacted in October 2019. The firm reported to have distributed Stacks tokens to over 300,000 customers — which corresponds to the quantity of “bc-” customers. Each of these folks was imagined to be verified by Blockchain, Inc. by means of a full know your shopper (KYC) process.
In a name with Cointelegraph, Blockstack PBC CEO Muneeb Ali defined that the blockchain doesn’t include any verification information that might expose personal person info, comparable to cellphone numbers or authorities IDs.
He confirmed that the “bc-” names are certainly ensuing from the Blockchain, Inc. airdrop. As for “fc-” names, Ali didn’t want to disclose their origin, however he talked about that they’re a part of a person acquisition technique that “the company will announce in the coming weeks,” whereas emphasizing that each one of them are verified.
Is Blockstack responsible of wrongdoing?
Commenting on the debacle, Ali believed it was a misunderstanding, saying that “people are under the impression we claimed to have one million active users.”
He defined that the milestone was outlined in 2017 in accordance with a really particular authorized definition, which required customers to be registered on the blockchain. However, it didn’t specify how they have been imagined to be verified — this was on the discretion of the corporate.
An SEC filing reveals that Blockstack paid Blockchain, Inc. as much as $3.85 million for the airdrop. Even although they have been paid for, the KYC requirement ensures that all the airdrop members are actual folks — one thing that the social verification system doesn’t assure.
Ali famous that the corporate largely moved away from social verification, exactly as a result of it could possibly be simply falsified. He additionally revealed that the staff is engaged on creating blockchain signature data for different sorts of verification.
Ali emphasised that the milestone was a self-imposed requirement, which he described as a testomony to Blockstack’s transparency.
While there may be some ongoing uncertainty over the origin of the “fc-” names — which is able to hopefully be cleared quickly — Blockstack may have simply created a military of pretend social media accounts that might have handed a superficial blockchain take a look at.
It additionally most likely would have been cheaper than paying Blockchain, Inc. for an airdrop that solely took it one third of the best way.
