Investment firm BlackRock is among the largest creditors of bitcoin miner Core Scientific, which filed for Chapter 11 bankruptcy last week.

Its subsidiaries committed $17 million of the new $75 million loan the miner got from convertible notes shareholders as part of its prearranged bankruptcy deal, according to a document filed with the U.S. Securities and Exchange Commission on Thursday.

BlackRock already owned $37.9 million in secured convertible notes as of Dec. 28. The miner went public last year via a deal with a special purpose acquisition company (SPAC), with BlackRock serving as anchor investor.
