Today is my first day as Head of DeFi at @Berachain!. For those who don't know me - .I've been in the trenches of the Berachain community for almost three years, and as @SmokeyTheBera used to say: "it's when, not if" I came on full time. Grateful to have found the ulitmate.

@redactedcartel, $BTRFLY, current market cap ~$100mn. Their Votium rewards alone are annualizing ~$15mn+.LP Fees account for another $5.5mn+.That's 20+% ROIC, not including $SPELL, $OHM, or bond related revenue- as there are more question marks around their yield right now.

Who wants to do some $OHM Math with me? . Current Price: $62.Current Backing: $54.47. As long as you remain staked, you can think of buying $OHM right now as paying a ~15% premium to the nominal value of the assets in the treasury. Your claim to this will remain ~fixed over time.

DeFi is undergoing a massive shift that will underpin much of the next few years of onchain growth. In prior cycles, DeFi was its own vertical, serving end-users directly. Increasingly, working in DeFi requires a combination horizontal + vertical mindset, as it becomes integral.

Why Does Berachain's Proof of Liquidity Matter? . Let's look at a quick example of a new L1 launch: .- $10b FDV.- 10% inflation for economic security to PoS Stakers.- $1bn in inflation / year .- $250m of TVL . Examples like this are quite common, and the majority of new launches.

222
If Boyco works as planned, I expect it to immediately become the de-facto way for new chains to onboard capital. Already heard of 2-3 ecosystems planning to use it going forward. Fully intending to continue contributing post launch, there's still a ton to add for a v2.

Man, I hope folks appreciate the sheer amount of work that has gone into making Boyco a reality. Would've been far easier to just make some vaults to deposit into a bridge contract and call it a day, but we believe in open, permissionless, and app-focused markets. Fat Bera Thesis.

Berachain has ~100 dApps that are planning on launching natively. Despite the chain potentially not being real, not a single one has decided to migrate to another chain. Study elite builder support. Study elite builder conviction.
some people say that @berachain not launching sooner is sub-optimal. I disagree. beras have just used the extra time to cook up way more crazy shit. never before will there be an eco that launches and has so many live apps from day 1. hell, thanks to boyco the chain will even.

Three months ago, post Blast, everyone was insanely bearish on using pre-deposit markets/vaults for a chain. Now, every upcoming chain launch I've seen will be using some variation of Boyco/pre-deposit vaults. The issue was never the vaults. The issue was the implementation.

Biggest takeaway from ETHDenver is that we have too many undifferentiated, general pupose L2s. Sequencer fees for these compress to zero on a 3-5+ year time horizon. As a result, you should focus on specialization, either as an appchain or as a vertical-specific chain.

Modular, Low cost, high throughput, and unified liquidity. 1) AggLayer v1 coming out EOM - <1min finality EOY.2) Connect any L2 to L2 seamlessly & natively.3) Connect any EVM L1 via Type1 prover to interop, no L2 migration needed.4) 30-50x proving efficiency & DA /Alt DA.
Releasing the Type-1 upgrade to the zkEVM prover, the next generation of Polygon’s proving tech. It can generate proofs for any EVM chain—sidechain, optimistic rollup, even Ethereum itself. When proving Ethereum mainnet blocks, avg per-transaction costs are $0.002 - $0.003.

Sometimes the hardest decision to make is doing things slow, the right way. Over the past year, we've worked tirelessly to bring zkEVMs to the market, shipping product, infrastructure, and core protocol upgrades. Now the next leg of the journey begins. Over the next two.
We launched Polygon zkEVM as the first full-featured, open source zkEVM ever made available. With that launch comes responsibility, including high levels of security and uptime. Thus, the last 10 months have been stage 1 of the Polygon zkEVM Mainnet Beta, focused on testing,

Some chains don’t care about DeFi. Some chains realize DeFi underpins almost every dApp, but don’t understand network effects of DeFi. The best chains will bring together smart DeFi builders, create & combine new primitives, and use to optimize consumer dApp UX.

Today we reveal Berachain's Request for Broposal (RFB). The RFB Program consists of three components:.- Boyco.- Request for Application.- Request for Community. RFB is designed to resource early teams & give a sneak peek into a novel way for apps to seed mainnet liquidity.

Berachain’s pre-launch ecosystem is the best of any chain in history. That is further exemplified by the RFA program, featuring 127 unique protocols deployed on Berachain’s testnets, and arming them with the resources to grow and succeed come Q5.
Berachain was built with an application-first vision. At every stage, the network's goal is to align incentives between the chain, builders, and users and encourage sustainable growth. Today we announce the 127 Projects that qualified for RFA, a program designed to help scale.

Went from broken to exploitative, we're moving up! Next leg is "Berachain is perhaps interesting", then we go full Berachain-pilled. I think much of the 'exploitative' angle here is again driven by a fundamental misunderstanding of PoL. Anyone that wants to get deep into Proof.
okay fuck I went from PoL seems broken to PoL seems exploitive. today:.User interacts with app, app pays user in app token. Bera: .User interacts with app, app bribes validators in app token, validator pays users in BGT. We introduced a validator intermediary into a pretty.

Berachain really using "Pre-Pre" to push the fake chain narrative as far as they can take it.
$350M later, we found another vault stuck in the mail. Now accepting stablecoin pre-deposits for Boyco with @Ethena_Labs & @ConcreteXYZ, with every last dollar going into Bera-native apps upon Boyco's launch. It's not a pre-deposit. It's a pre-pre deposit - the Q5 special.

At this point, @Polymarket is becoming one of the most mainstream crypto applications. Study it. No Token, all driven by UX, great product, and based intern.
Polymarket is predicting that blobs (~125 kB) will cost ~0.001 ETH. Today, 125 kB calldata costs ~30 gwei per gas * 16 gas per byte * 125000 gas ~= 0.06 ETH. And if you think polymarket's guess that blobs will be 60x cheaper is over-optimistic, you can use the market to hedge!
