Adam Back Warns Against Rise of ‘JPEG Spam’

Adam Back, an early Bitcoin developer and the co-founder and CEO of Blockstream, has weighed in on the talk about what he calls “JPEG spam” on the Bitcoin blockchain.

Back argues that it undermines the cryptocurrency’s core function as cash in a thread on X (previously Twitter) on Friday.

Bitcoin needs to be thought of “owned by humanity” with builders performing as “stewards” who require consumer consensus to alter the community materially, Back mentioned. That precept, he added, was bolstered throughout the block-size wars of 2015–2017, when user-led financial stress stopped miners from pushing by protocol modifications.

Back took intention on the surge of JPEG inscriptions—photos saved immediately on Bitcoin by the Taproot improve and the Ordinals protocol that it helped spawn.

The quantity of JPEGs embedded in Bitcoin’s ledger has risen from 88 million in May to 105 million in September, a 20% enhance. Fees tied to those inscriptions complete roughly 7,000 BTC ($777 million).

Bitcoin’s core mission

The proponents of developments enabled by the Taproot improve, equivalent to Ordinals, in the meantime, argue that so long as customers are prepared to pay for block area, they’re a legitimate use of the community.

Being a permissionless system, there needs to be no dictating of what Bitcoin can and can’t be used for, as this goes towards the ethos of decentralization upon which it was constructed.

Furthermore, the “JPEG spam” additionally strengthens the financial incentive for miners to keep up the Bitcoin community, which might turn into more and more very important because the block rewards they obtain are minimize by 50% each 4 years.

While miners profit from increased charges, Back argues the impact is minimal as soon as the hashrate has elevated and prices are factored in. He estimated that JPEG inscriptions might contribute simply 0.1% to mining income, far outweighed by potential reputational hurt, increased transaction prices for abnormal customers, and diminished accessibility to Bitcoin’s core perform as a peer-to-peer cash system.

Divided group

The challenge is subsequently a divisive one within the Bitcoin group.

Supporters view inscriptions as legit financial exercise and the use of the blockchain. Critics, together with Back, say they waste block area and displace exercise that strengthens Bitcoin’s worth proposition.

Back floated attainable cures, together with outreach to miners and swimming pools to discourage processing such transactions, and wallet-level modifications that would steer charges towards these rejecting them. While warning of centralization dangers, he recommended even small financial nudges might make mining JPEG inscriptions unprofitable.
