03/05/2022 Solana Goes Dark for 7 Hours as Bots Swarm ‘Candy Machine’ NFT Minting Tool

It wasn’t immediately clear how the bot traffic overcame network safeguards.

Solana stakeholders rushed to right the network Saturday night after what one insider called “insane amount of data” flooded theproof-of-stakechain, knocking validators out of consensus and grinding block production to a halt.

Bots had swarmed the popular non-fungible token (NFT) minting tool known as Candy Machine earlier Saturday with an unprecedented tsunami of inbound traffic: four million transaction requests and 100 gigabits of data every second – a record for the network, one person at the Solana Foundation said.

For reasons not yet clear, this swarm pushed validators out of consensus. Block production became impossible and the network went dark at 4:32 p.m. ET. By 11 p.m. ET, validators (coordinating through Solana’s Discord channels and aGoogle doccreated by one of the validators) restarted the cluster at slot 131973970.

Co-founder Anatoly Yakovenko, who said he was traveling during much of the fracas, credited the validator community for spearheading mainnet recovery. He'd caughtflakon Twitter Saturday for allegedly being "MIA" during a network crisis.

Unlike lastSeptember’s17-hour outage, Saturday’s hard fork restart did not resolve with new-and-improved code populating across the validators. It simply picked up where the network flopped seven hours prior.

In preparing for the restart validators mulled whether to implement code that would temporarily block Candy Machine transactions. Some debated in the Discord whether such a move constituted censorship. Regardless, it would only be effective if two-thirds of validators opted in. Few appeared to do so on Saturday night.

Other parts of the ecosystem quickly moved to bolster their defenses. At 11:36 p.m. ET, Metaplex, the key steward of Solana NFT infrastructure and one closely intertwined with Candy Machine,tweetedit would soon deploy a 0.01 SOL “botting penalty” to help NFT projects stanch excessive traffic.

Solana ecosystem services like Phantom wallet and decentralized exchange Mango Markets struggled to stand up in the aftermath as RPC node providers plodded back online.

The outage contributed to a bloody, albeit brief, drawdown in SOL markets. Solana’s native token crashed to a 24-hour low of $83.13 about three hours into the outage before climbing back toward $89, according to CoinGecko.

Solana core developers have yet to diagnose what went wrong Saturday or how the apparent botting attack overcame existing safeguards to stymie consensus, a member of the foundation told CoinDesk.

José Delbo sent me his striking pencil sketch and powerful inked work, which I then interpreted in oil on canvas. I wanted to create a very painterly piece with obvious brush marks etc, but I was also aiming for a nostalgic feel, a kind of 1980’s superhero comic book look, the kind I grew up with. My goal with this animation was to try to recreate, in part, the creative process that both artists went through with the visual information I had. I was able to showcase my painting process more accurately as I could take photographs of my progress throughout. Consecutive images could then be layered like brush strokes over José’s drawing to create the impression that this was one continuous artwork from pencil, to ink, to completed painting. The representation of the line sketch at the beginning, then pencil/ink and lastly the paint layers being applied demonstrate both artists’ struggle for the right lines, tone, form, and colour until the work is finally completed. As the oil was still wet with each photograph the glare of my studio lights can be seen in the brush strokes. Eventually, the figure emerges and as it does, our hero comes to life, looking directly at the viewer -- but is he grimacing in approval or disgust? We will never know for sure as just before he can say anything, white paint is brushed across the canvas entirely and the process begins again. Only the bat is quick enough to escape.

There are an almost infinite number of ways to wrap a string around a set of pegs. On the surface it may seem like a simple concept but prepare to be surprised and delighted at the variety of combinations the algorithm can produce. Each output from 'Ringers' is derived from a unique transaction hash and generated in Javascript in the browser. Feature variations include peg count, sizing, layout, wrap orientation, and a few colorful flourishes for good measure.
