Blockstream CEO Adam Back publicly questioned the inflation mechanics of Telegram's GRAM token this week, firing back at Pavel Durov's praise of Bitcoin as a defense against government money printing. In a pointed response, Back argued that Bitcoin's monetary credibility depends on a fixed, auditable issuance schedule that no governance decision can override — a feature GRAM doesn't share.
Back's critique of GRAM's inflation
GRAM has no hard supply cap. It generates new tokens daily through validator rewards, with an annual inflation rate of roughly 0.3% to 0.6%. Total supply now sits near 5.2 billion tokens. Back pushed back against Durov's framing, arguing that a token with adjustable issuance can't claim the same sound-money properties as Bitcoin. “Bitcoin's credibility is its fixed schedule,” Back said in a public post. “Once you let validators or governance tweak supply, you've lost the very thing that makes it a hedge against central bank printing.”
The critique arrived after Durov touted Bitcoin as his primary personal reserve — a position he's held for over a decade. Durov bought roughly 2,000 BTC in 2013 at an average price around $700 per coin. That stash would be worth hundreds of millions today.
Durov's long-standing Bitcoin position
Durov's Bitcoin holdings aren't new. He's been public about using it as a store of value since the early days. His recent comments praising Bitcoin's role as a check on inflation drew a direct line from his own experience to the broader argument for hard money. But Back zeroed in on the contradiction: Durov runs a project whose native token inflates over time, even if slowly.
The Telegram token recently underwent a rebranding from Toncoin to GRAM, with all existing holdings converted at a 1:1 ratio. Exchanges updated their listings accordingly. The move was meant to unify the brand, but it didn't change the token's underlying economics.
The token's supply model
GRAM's validator rewards keep the supply growing. The inflation range — 0.3% to 0.6% annually — is modest compared to fiat currencies, but it's not zero. And crucially, it's not pre-determined. Validators, not code, decide the pace. That's a fundamental difference from Bitcoin, where miners follow a fixed subsidy halving schedule that no one can alter without a fork.
Back has a track record of defending that principle. Earlier in 2026, he rejected a contested fork proposal, arguing that changing Bitcoin's core rules produces a separate asset, not an upgrade. The same logic applies here, he implied.
What's unresolved
Durov hasn't directly responded to Back's critique. The question hanging over GRAM is whether its inflation model matters to users who see it mainly as a utility token for the Telegram ecosystem. For now, the debate highlights a deeper split in crypto: between projects that prioritize fixed supply and those that leave room for governance adjustments. Back's side is clear. Whether the market agrees is another story.
