DoubleZero Launches Green Candle Cup, a $50,000 No-Fee Solana Trading Competition

DoubleZero 2Z$0.033-3.9% opened registration today for the Green Candle Cup, a seven-day live trading competition on Solana offering $50,000 in prizes with no entry fee. According to DoubleZero, registration closes September 1 and trading runs September 1 through 8. Participants get free access to the same infrastructure stack DoubleZero and its affiliates sell commercially: DoubleZero's low-latency dedicated fiber, Triton One's ShredStream, and the Phoenix central limit order book.

All three organizations are affiliates of Solana's Frontier Trading community, the platform through which participants register for the event.

Triton One ShredStream: Block Data Before the Block Is Assembled

The technical centerpiece for competition participants is Triton One's ShredStream. Shreds are the earliest form of Solana block data available: validators produce them during block assembly, before a block is finalized and propagated across the network. Standard RPC nodes wait for Turbine, Solana's block-propagation protocol, to distribute completed blocks. ShredStream bypasses that wait.

Triton routes shred packets directly to a UDP port on the participant's own server, in real time, as validators produce them. Participants then reconstruct transactions using the open-source deshred pipeline. The result is access to transaction data before block confirmation rather than after propagation.

Setting up ShredStream requires a Triton account, a server in one of five supported data centers (Frankfurt, Amsterdam, New York, London, or Tokyo), and the IP address and UDP port to receive the stream. Triton One is providing a dedicated support channel and open engineering office hours for competition participants throughout the event.

Phoenix Trade as the Competition CLOB

Trading executes on Phoenix, Ellipsis Labs' on-chain central limit order book. Phoenix matches orders directly on-chain without an off-chain crank, making it the exchange of choice for a competition structured around on-chain execution speed. Phoenix has been expanding its market list; the exchange added seven equity perpetuals, including Netflix and CrowdStrike markets, earlier today, bringing its total to approximately 29 markets.

DoubleZero Edge: From Institutional Clients to Open Competition

DoubleZero's private fiber currently carries data for 62.6% of Solana's stake weight, according to the foundation's second-anniversary update published last week. The data-distribution layer on top of that fiber, DoubleZero Edge, has been growing its institutional roster throughout the year. Kalshi began streaming live order books on Edge in August, becoming the first prediction market on the platform.

The Green Candle Cup gives traders with servers in supported data centers free access to the full infrastructure stack for seven days. DoubleZero described the event as an opportunity to "try DoubleZero Edge for free."
