There's around $15.7B in stablecoins on Solana right now. Boring money needs boring execution: predictable, private and close to the block. The exciting part is where it lands.

Blackline doesn't see the future. It sees the present sooner than anyone else on the network. That's the whole edge. It's enough.

Solana's transaction count dropped by about two-thirds after Alpenglow. Nothing's broken. Our CEO Robin Nordnes called it ahead of the switch, quoted in @CoinDesk and @CoinMarketCap: "Most of what got counted before was validators voting, and that's off-chain now. The trading's all still there. For desks, faster finality is nice, but it was never the bottleneck. Being close to where the block is built still is."

In equities, the venue is a building in New Jersey. On Solana, the venue moves every few hundred milliseconds, to whichever validator is building the block. You can't rent a rack next to that. You have to be on it.

Circuit revisited: tokenized domains with @domaprotocol @SDMikeCM joined us to talk about a market he calls a $360B industry that still trades through checks, escrow and NDAs, and why Doma thinks the fix is putting domains onchain. πŸ‘‰ Watch the full episode: x.com/raikucom/status](xitter.cf/raikucom/status/211035…)

Institutions aren't waiting for Solana to get faster. It already did. What's holding them back is the boring stuff: where their orders sit, and who's close to the block when it's built. Robin on the real blockers πŸ‘‡

A solana slot is, as of right now, ~200ms. Here's what happens inside one, and why where you sit matters.

Traditional markets solved this decades ago: put your server beside the exchange.

On solana, the exchange is the validator building the block. Blackline puts your strategy on the same hardware. Visit Raiku for more.

Nine public companies just objected to OKX and ICE tokenizing their stock. @Cointelegraph covers the issuer pushback under the SEC’s innovation exemption, including Broadcom, Verizon and UnitedHealth. Our CEO @degenroot: β€œIssuers aren’t objecting to the blockchain. They’re objecting to not knowing what happens to their price once it trades there. On a public chain, the validator building the block sets the order. Until desks can measure their distance to that point, best execution is a promise, not a number.

Everyone on Solana is measuring how close they can get to the block. We went with zero. Blackline runs your strategy on the same hardware as the validator that builds it. Trade where the block is built.
