OXT researcher verifies Grayscale’s bitcoin holdings
Five days ago, Bitcoin.com News reported on Grayscale disclosing information related to the safety and security of the company’s digital assets. Grayscale’s statements were meant to assure the public that the company’s cryptocurrencies are “safe and secure” following the collapse of FTX.
The digital asset fund manager clarified that all of the company’s digital assets are stored with Coinbase Custody Trust Company. On Grayscale’s website, the company states that Coinbase Custody is a qualified custodian under New York banking laws and funds are held in “cold storage.”
The only thing Grayscale didn’t disclose were the addresses of the company’s digital assets and it mentioned why it chose not to share the wallets. Grayscale explained that it has never publicly disclosed on-chain addresses to the general public “for security reasons.” The allegation was criticized and mockedbut Grayscale said it understands non-disclosure would be “a disappointment to some.”
Despite Grayscale’s non-disclosure, the OXT researcher (oxt.me) ergonomics explained that he started a community-led effort to create transparency around GBTC’s holdings. “We have taken steps to identify probable GBTC addresses and balances based on public information and blockchain forensics,” Ergo said November 20.
Leveraging a Coindesk article, heuristics, and publicly known bitcoin addresses associated with custodian Xapo, that day Ergo “assigned 432 addresses holding 317,705 BTC probable custodial activity of GBTC.
The researcher uncovered at least 50% of GBTC’s holdings and added: “further work is required to identify the remaining addresses.” As of 2:49 p.m. (ET) on Nov. 23, Ergo said the additional work was complete in a Twitter thread titled, “The Grayscale G(BTC) Coins Part 2” Ergo tweeted:
Ergo’s summary notes that after discovering the first 50% of bitcoins associated with Grayscale BTCthe team had to “scan the blockchain” to find additional addresses matching the profile of those found in Part 1.
Ergo also leaves independent analysts with information about heuristic used and the bitcoin addresses compiled for research. “Obviously, no heuristic or set of heuristics is perfect, and this analysis certainly includes false positives and false negatives,” Ergo noticed. “But our result is almost identical to the G(BTC) self-reported assets.
In the Twitter thread, Ergo says he doesn’t know why Grayscale decided not to share company information. BTC addresses. Ergo said the team originally thought Coinbase Custody might have a non-disclosure policy. But after reading some information published by Coinbase, Ergo said “It seems clear that Coinbase Custody is willing to release the addresses.”
A Number people complimented Ergo’s Twitter feed and GBTC parts analysis. Additionally, the news follows Coinbase CEO Brian Armstrong explaining that as of September 30, Coinbase holds 2 million bitcoins.
