00:00:08 Ethereum Project Update: Organizational, Technical, and Future Plans
Ether Sale Results: 31,500 BTC, 60 million Ether, 18.4 million USD raised. Over 9,000 purchases, with most people participating at the start and end. A large number of people waited until day 14 to purchase, leading to a spike in purchases. Top 100 purchasers received 40.7% of Ether, compared to 25% for Bitcoin and 55-60% for altcoins. Gini index of 0.830, indicating a relatively high level of inequality in Ether distribution.
Project Organizational Updates: Berlin will be the main development hub for C++ development, Whisper, Swarm, economic modeling, and testing. Amsterdam will be the center for Go development, with potential for other locations.
Protocol Updates: Proof of Concept (PoC) 5 released with two clients in sync, later joined by Python. PoC 6 will introduce a new version of the ghost protocol, reducing block times from 60 seconds to 12 seconds. New opcodes, including doPend, swapPend, AdMod, MulMod, ExtroCodeSize, and ExtroCodeCopy, for deeper stack exploration, modular addition and multiplication, and copying other contracts’ code. PoC 7 will focus on adding a consensus algorithm, such as async-resistant proof of work.
Proof of Stake: Ethereum’s long-term goal is to transition from proof-of-work to proof-of-stake to address energy inefficiencies. Proof-of-stake involves using coins as a stake to validate transactions, rather than wasting CPU power on mining. ASIC-resistant proof-of-work is an earlier effort to make proof-of-work resistant to hardware specialization.
ASIC Resistant Proof of Work: Vitalik Buterin discusses the issue of ASIC centralization in Bitcoin mining and the efforts to create an ASIC-resistant Proof of Work for Ethereum. The aim is to design a function that can be efficiently executed on general-purpose hardware, preventing the dominance of specialized ASIC miners.
Proof of Stake Component: Ethereum is incorporating a Proof of Stake component to reduce the overall inefficiency of the mining process.
Native Extensions: Native extensions allow for more efficient execution of certain operations within Ethereum contracts. These extensions are written in C++ and simulate the desired functionality, significantly reducing the gas cost of complex operations. Native extensions enable the integration of cryptographic functions, complex data structures, and other computationally intensive tasks.
Contract ABI Standardization: Efforts are underway to standardize the way contracts are written and called in Ethereum. The goal is to streamline the process of writing contracts, making them more efficient and easier to use.
Alarm Opcode: The Alarm opcode is being developed to enable the execution of code at a specified time in the future. This feature opens up possibilities for decentralized scheduling and time-based applications.
Microgenes: Microgenes are highly technical details that may not have a significant impact on Ethereum’s functionality. The decision to include or exclude them is still being considered.
Challenges and Considerations: The complexity of certain operations within Ethereum, such as heaps and elliptic curve signatures, can introduce inefficiencies. Native extensions address these inefficiencies by providing more efficient implementations of complex operations. The pricing of native extensions and opcodes is a consideration to ensure fair and balanced usage.
Benefits of Native Extensions: Native extensions expand Ethereum’s capabilities beyond business logic to include arbitrary cryptographic verifications. This versatility makes Ethereum useful for a wider range of applications, including decentralized markets, prediction markets, and complex cryptographic computations.
Proof-of-Stake vs. Proof-of-Work: Ethereum is looking to use a combination of proof-of-stake and proof-of-work for its consensus algorithm, rather than pure proof-of-work. Proof-of-stake is more efficient and potentially stronger than proof-of-work, as it’s harder to get 50% of the currency units than 50% of the work.
Nothing-at-Stake Problem with Proof-of-Stake: In proof-of-stake, voters can vote on every fork of the blockchain simultaneously, leading to a lack of consensus. This issue is called the “nothing-at-stake” problem and undermines the effectiveness of proof-of-stake as a consensus algorithm.
Slasher Mechanism to Address Nothing-at-Stake: Vitalik Buterin proposed the “slasher” mechanism to address the nothing-at-stake problem. In this mechanism, voters are chosen ahead of time and must wait 3,000 blocks before receiving their reward. Double voting is punishable by a slashing penalty, deterring voters from voting on multiple forks.
Long-Range Nothing-at-Stake Problem (LRNAS): The slasher mechanism addresses the nothing-at-stake problem within a 3,000-block window, but a longer-range attack could still occur. Two proposed solutions to LRNAS are “transactions as proof-of-stake” and “custody mining.”
Transactions as Proof-of-Stake: This approach uses transactions as votes, with each transaction including a hash or part of a hash of a recent block. Transactions voting on a fork that becomes invalid lose their value, disincentivizing voters from casting votes on multiple forks.
Custody Mining: This approach adds a bit of proof-of-work to the proof-of-stake mechanism. The mathematical argument suggests that double voting becomes less profitable than the expected return, deterring attackers.
Conclusion: Ethereum’s consensus mechanism is still under development, with Vitalik Buterin proposing various solutions to address the challenges of proof-of-stake. The combination of proof-of-stake and proof-of-work aims to improve efficiency, security, and resistance to attacks.
00:25:10 Ethereum: Proof-of-Stake, Whisper, Swarm, and Decentralized Applications

The sale’s structure and the resulting wealth distribution, with a Gini index of 0.830, highlight both opportunities and concerns regarding inequality within the ecosystem. This distribution reveals that the top 100 purchasers received 40.7% of Ether, compared to 25% for Bitcoin and 55-60% for altcoins. Additionally, over 9,000 purchases were made, with most people participating at the start and end of the sale. However, a large number of people waited until day 14 to purchase, leading to a spike in purchases.
*Project Organizational Updates:*
– Development hubs in Berlin and Amsterdam signify Ethereum’s commitment to advancing its technical capabilities, focusing on various aspects like C++ development, economic modeling, and potential expansions. Berlin will be the main hub for C++ development, Whisper, Swarm, economic modeling, and testing, while Amsterdam will be the center for Go development, with potential for other locations.
*Protocol Updates:*
– Ethereum has made significant strides in its protocol development through various Proof of Concept (PoC) updates. These include syncing of C++ and Python clients, a new ghost protocol in PoC 6, and the ongoing development of PoC 7, which plans to introduce an async-resistant proof of work. PoC 5 was released with two clients in sync, later joined by Python. PoC 6 introduced a new version of the ghost protocol, reducing block times from 60 seconds to 12 seconds. PoC 7 will focus on adding a consensus algorithm, such as async-resistant proof of work. Additionally, new opcodes, including doPend, swapPend, AdMod, MulMod, ExtroCodeSize, and ExtroCodeCopy, have been introduced for deeper stack exploration, modular addition and multiplication, and copying other contracts’ code.
*Proof of Stake:*
– PoS emerges as a promising alternative to proof-of-work (PoW), offering energy efficiency, security against attacks, and enabling more complex governance mechanisms. However, challenges like the “Nothing-at-Stake” problem and long-range attacks necessitate innovative solutions to ensure system integrity. Ethereum’s long-term goal is to transition from proof-of-work to proof-of-stake to address energy inefficiencies. Proof-of-stake involves using coins as a stake to validate transactions, rather than wasting CPU power on mining. ASIC-resistant proof-of-work is an earlier effort to make proof-of-work resistant to hardware specialization.
*Challenges and Solutions:*
– Ethereum faces various implementation challenges, particularly in PoS, due to the complexity of assets and Ether ownership. Proposed solutions include mechanisms like Slasher, transactions as proof-of-stake, and custody mining to mitigate risks associated with PoS. The slasher mechanism addresses the nothing-at-stake problem within a 3,000-block window, but a longer-range attack could still occur. Two proposed solutions to LRNAS are “transactions as proof-of-stake” and “custody mining.”
*Current Status and Native Extensions:*
– Ethereum’s move towards PoS is under active development, with various research teams contributing to this transition. Additionally, native extensions introduced in Ethereum expand its functionality and efficiency, though they present challenges in determining appropriate gas costs and ensuring security. Native extensions allow for more efficient execution of certain operations within Ethereum contracts. These extensions are written in C++ and simulate the desired functionality, significantly reducing the gas cost of complex operations. Native extensions enable the integration of cryptographic functions, complex data structures, and other computationally intensive tasks.
*Consensus Algorithm:*
– A hybrid consensus algorithm combining PoS and PoW is under consideration, balancing the advantages of PoS with the traditional strengths of PoW. Ethereum is looking to use a combination of proof-of-stake and proof-of-work for its consensus algorithm, rather than pure proof-of-work. Proof-of-stake is more efficient and potentially stronger than proof-of-work, as it’s harder to get 50% of the currency units than 50% of the work.
*Ethereum 1.0 Core Priorities and Decentralized Applications:*
– Core priorities like virtual machine optimization, security, and consensus, alongside user interface improvements and mobile client implementations, are vital for Ethereum’s growth. Decentralized applications such as Whisper, Swarm, and Shelling Point demonstrate Ethereum’s potential beyond financial transactions. Whisper is a generalized peer-to-peer messaging system, while Swarm is a generalized peer-to-peer data storage system. These protocols are being developed to enable decentralized applications and internet services. Shelling Point is a decentralized oracle system that allows Ethereum contracts to access real-world information.
