1 00:00:14,230 --> 00:00:20,677 [HOST] Welcome to X1 Report, your source for the latest in blockchain news. Today, we're diving 2 00:00:20,677 --> 00:00:26,977 into a significant development in the Solana ecosystem: the reduction of Solana's slot 3 00:00:26,977 --> 00:00:33,350 time to 350 milliseconds, aligning with X1's consistent block production rate since its 4 00:00:33,350 --> 00:00:34,083 inception. 5 00:00:34,083 --> 00:00:41,248 [ANALYST] This engineering milestone marks a convergence between Solana and X1, two sister chains 6 00:00:41,248 --> 00:00:48,494 sharing the same virtual machine and client lineage. The reduction from 400 milliseconds 7 00:00:48,494 --> 00:00:54,424 to 350 milliseconds represents a 12.5% decrease in target slot duration. 8 00:00:54,424 --> 00:01:01,481 [HOST] The transition was carefully managed, with the first of four reductions under SIMD-0525 9 00:01:01,481 --> 00:01:08,701 taking effect at the start of epoch 1020. This change brings Solana's slot time closer to 10 00:01:08,701 --> 00:01:13,162 X1's consistent rate of approximately 366 milliseconds. 11 00:01:13,162 --> 00:01:19,678 [ANALYST] To measure the effectiveness, we compared both networks using getBlockTime from their 12 00:01:19,678 --> 00:01:26,270 public RPCs. Over several epochs, the measured slot times for Solana and X1 have shown 13 00:01:26,270 --> 00:01:33,015 remarkable consistency, with both currently producing blocks at around 366 milliseconds. 14 00:01:33,015 --> 00:01:39,376 [HOST] This convergence is not just a coincidence. Both chains run Tachyon, a client from the 15 00:01:39,376 --> 00:01:45,515 same lineage as Solana's Agave, on the same Solana Virtual Machine. Their inflation 16 00:01:45,515 --> 00:01:52,172 schedules are also strikingly similar, with both starting at 8% and tapering down to 1.5%. 17 00:01:52,172 --> 00:01:58,870 [ANALYST] However, there are key differences. X1's most notable departure is that votes are free, 18 00:01:58,870 --> 00:02:05,799 removing the $250/SOL cost for validators on Solana. This change aims to lower the barrier 19 00:02:05,799 --> 00:02:09,726 for honest participation and combat centralization. 20 00:02:09,726 --> 00:02:16,643 [HOST] X1 also introduced Project Capybara, which reshaped Foundation delegation around a P85 21 00:02:16,643 --> 00:02:23,802 percentile self-stake threshold, directing delegation towards operators with real capital 22 00:02:23,802 --> 00:02:25,330 and uptime at risk. 23 00:02:25,330 --> 00:02:31,313 [ANALYST] Despite these differences, X1's slot time has shown remarkable stability. Sampling 24 00:02:31,313 --> 00:02:37,369 consecutive blocks across several epochs revealed that the network sustained multi- 25 00:02:37,369 --> 00:02:42,257 thousand TPS traffic for days without degrading the block interval. 26 00:02:42,257 --> 00:02:50,151 [HOST] The throughput record on X1 is not a spike but a plateau. The highest recorded throughput 27 00:02:50,151 --> 00:02:58,044 of 29,134.2 TPS was maintained over a full week, with slot times staying in the 330–370ms 28 00:02:58,044 --> 00:02:58,488 band. 29 00:02:58,488 --> 00:03:05,812 [ANALYST] The next steps in Solana's upgrade are outlined in SIMD-0525, which will further reduce 30 00:03:05,812 --> 00:03:13,305 slot times to 300, 250, and finally 200 milliseconds. Each step carries a one-epoch delay 31 00:03:13,305 --> 00:03:16,251 and is behind its own feature gate. 32 00:03:16,251 --> 00:03:23,581 [HOST] For now, X1 and Solana produce blocks roughly every 366 milliseconds. One of them has just 33 00:03:23,581 --> 00:03:30,829 finished a substantial coordinated upgrade to get there, while the other has been running 34 00:03:30,829 --> 00:03:33,109 that way since October 2025. 35 00:03:33,109 --> 00:03:39,476 [ANALYST] The parameter scaling, shred-limit handling, and phased activation pattern are all 36 00:03:39,476 --> 00:03:46,387 published and applicable to any SVM network. X1's path forward is well-mapped, and it has 37 00:03:46,387 --> 00:03:50,036 demonstrated a tolerance for a sub-400ms clock. 38 00:03:50,036 --> 00:03:56,491 [HOST] That's the latest from the world of blockchain.
