Does Crypto Need L1s?

Crypto, and everything within it, is evolving. Despite that, we must focus on preserving the true values of decentralized finance.

Key takeaways

  • Alephium is a proof-of-work layer 1 that aims to combine Bitcoin-style security, Ethereum-style smart contracts and more than 20,000 transactions per second.
  • Pep revealed the name of Alephium's native DEX, Powfi (proof-of-work finance), a hybrid CLMM and CPMM exchange built in six months.
  • Powfi is written in Ralph, Alephium's own smart contract language, which is designed to prevent common exploits like double spending.
  • Alephium's proof-of-less-work design could cut miner energy use by up to 87% under Bitcoin-like conditions, according to Pep.
  • A grant-backed tool called HenryCoder translates Solidity into Ralph to help developers onboard.
  • Pep measures success by community sentiment, builder growth and proving DeFi can thrive on proof of work without selling out to institutions.

Building one thing at a time, in any market

In this remote Hodl Up episode, Pep the Ghost, head of marketing at Alephium, joins after months of scheduling. He opened with a realist's view of the market: "We're at the dippiest point of the dip." He expects consolidation, with chains that keep shipping outlasting those that burned their runway on events and booths.

The conversation covers the Powfi DEX launch, why Alephium builds in bear markets, the Danube upgrade and proof of less work, the Ralph programming language, the fight against AI-written content, decentralization, and why prediction markets are more than gambling.

Powfi, proof-of-work finance

Pep shared Powfi's name ahead of its reveal. It is a hybrid CLMM and CPMM decentralized exchange that Alephium's developers built in about six months, starting the day Pep joined in late August. "I would say this is just about the most secure DEX possible. It's built on proof of work in our own exploit-resistant language."

Powfi launched on a public testnet on February 17 with bug bounties, and ALPH staking is being built for mainnet. Pep stressed that Powfi is designed to support, not compete with, other Alephium DEXs. Because it is composable, every dApp can integrate it and benefit from new liquidity.

Why launch in a bear market

From his time as a senior copywriter at an agency, Pep saw many teams build quietly in stealth during the 2022 bear market. Alephium, on mainnet for more than four years, follows a simple policy: announce one important thing, build it, test it, ship it, then move on. "We are absolutely focused on our mission."

The mission is DeFi on proof of work. Pep described Alephium as combining "the security of Bitcoin, the smart contract programmability of Ethereum, and the scalability of Solana," though he acknowledged it does not reach Solana's throughput.

The table below summarizes Alephium's design as Pep described it.

Danube, proof of less work and Ralph

Pep said the Danube upgrade halved transaction and confirmation times. Listing sites may show an unlimited supply after it, but he said emissions and burns continue at the same rate. Proof of less work balances mining with a burn mechanism, so under Bitcoin-like demand, miner energy use could drop by up to 87%.

Ralph is a real barrier for developers used to Solidity or Rust, and Pep admitted it. Alephium funds HenryCoder and hackathons to help. Developers who learn Ralph report that tasks taking eight hours in Solidity can take 15 minutes, "and without the possibility of exploits."

Authentic content in an AI world

A career copywriter, Pep splits audiences into value extractors and long-term believers, and writes long-form thought leadership for the latter. He is frustrated with AI-written posts. "As soon as I start reading a post that has all those classic AI tropes, I don't want to read it." He would rather see AI used to verify content than write it.

Decentralization and community

Pep described Alephium as "very highly decentralized, but we're not perfectly decentralized." During the October AWS outage, the chain kept running while some dApps did not. Founder Cheng Wang, a PhD cryptographer, designed Alephium as "a next-century technology" meant to thrive without human management one day.

Pep highlighted ecosystem projects Aura Markets, a decentralized prediction market with community resolution, and Linx, a lending protocol that passed 330,000 in TVL within weeks. As a former journalist, he values prediction markets for surfacing information. "I think we can get closer to real news with community conviction."

His measure of success: a large, happy community, more Ralph developers, and people calling Alephium the chain that revitalized proof of work "without having to sell out to institutions."

FAQ

Frequently asked questions

What is Alephium?

Alephium is a proof-of-work layer 1 blockchain with smart contracts written in its own language, Ralph. It aims to combine Bitcoin-style security with Ethereum-style programmability, supports more than 20,000 transactions per second and focuses on growing DeFi on proof of work.

What is Powfi?

Powfi, short for proof-of-work finance, is Alephium's native decentralized exchange. It is a hybrid CLMM and CPMM DEX written in Ralph, launched on a public testnet with bug bounties, and designed to add liquidity that other Alephium dApps can integrate.

What is proof of less work?

Proof of less work is Alephium's energy mechanism. It balances mining with a burn system, so as activity grows toward Bitcoin-like levels, miner energy consumption can fall by up to 87%, according to head of marketing Pep the Ghost.

What is the Ralph programming language?

Ralph is Alephium's smart contract language, designed to prevent common exploits such as double spending. Developers can use HenryCoder, an AI tool funded by an Alephium grant, to translate Solidity code into Ralph.
