Market News

News: Alpenglow lands today

CoinDesk: Solana sets Oct. 21 for Alpenglow

  • Replaces TowerBFT in epoch 1064, est. ~7:20 AM CDMX
  • Finality: ~12.8 s today, ~150 ms target
  • Switches at slot 459,653,000 after ~18 min

Why it matters

  • Near-instant settlement, e.g. instant point-of-sale confirmation (Solana)
  • Merchants and bridges can act on payments sooner (CoinDesk)
  • Votes leave blocks: ~1 SOL/epoch vote fees become a flat 0.8 SOL (Solana)

For analysts: votes leave blocks, so TPS drops; expect a ~2-slot gap. Check getAgGenesisCert. More: CoinDesk · Triton guide

News: USDC: the EU's first "significant" stablecoin

Cointelegraph: EBA labels USDC a significant e-money token

  • First of 45 e-money tokens to get the MiCA label
  • EBA supervises reserves, liquidity, redemption plans from Nov 12
  • France's ACPR keeps governance; EBA signed an MoU with NY DFS

For analysts: reviewed yearly, so EU holders, market cap and tx counts now count. Coverage: Cointelegraph

Chart: Solana vote vs non-vote transactions, Aug 24–30, 2026

Solana vote vs non-vote transactions, Aug 24–30, 2026 Caption: Mainnet, Aug 24–30, 2026 (from the exercise)

  • Votes were 49% of Solana transactions, Aug 24–30
  • Unsplit "transactions per day" charts don't measure app activity
  • Puzzle: daily vote vs non-vote totals from blocks only

Catch: votes beat non-votes on 3 of 7 days.

blocks(slot, height, block_time, block_date,
  total_transactions, total_vote_transactions,
  total_non_vote_transactions,
  failed_non_vote_transactions)
-- expected: block_date | vote_transactions | non_vote_transactions

Chart of the Week, powered by Allium

Chart: Faster blocks, same user activity

Allium chart: Solana blocks per day jump after slot times were cut to 200 ms on Oct 9, while non-vote transactions per day do not rise Caption: Solana blocks/day vs non-vote txs/day · Sep 15 – Oct 20 · Allium Explorer

  • +23.2% blocks/day
  • −5.2% non-vote txs/day
  • 85.5% → 87.9% success rate

Since 200 ms slots (Oct 9), blocks and votes rose ~23% but user activity didn't; Alpenglow pulls votes out of blocks next. (7-day averages, Oct 2–8 vs Oct 10–16, Oct 9 excluded.)

Pairs with the WizardCamp exercise above.
