CZ then tweeted that what is available now is only the first iteration of what will be available via Merkle Tree PoR in the near future.Related: Binance tops up SAFU fund at $1 billion amid price fluctuationsFollowing Binance’s example, many other platforms in the space began releasing their financial reserve and liquidity information in an effort of transparency. Chainlink Labs, Bitfinex and ByBit were among some of the first to come forward with their own data.However, the cryptocurrency investment product servicer Grayscale has withheld its on-chain PoR due to what it says are security concerns. It did release a letter from Coinbase Custody which verified that Grayscale’s crypto holdings are fully backed, yet withheld wallet addresses.
