A paper reviewing the incentive model of Ethereum’s Proof-of-Stake design. The authors set up a framework to evaluate economic security in Eth2 and model the impact on yields in various scenarios. The main results are a bunch of interesting conclusions and recommendations (at the beginning of the paper):
- At 13.8% of ETH staked, security levels of Eth2 will match those of Eth1 PoW given historical prices.
- 77.7% of the total ETH supply is held in non-exchange wallets with over 32 ETH.
- Network inflation will likely be significantly lower with PoS compared to PoW.
- Lack of liquidity in phase 0 and 1 might cause unpredictability and centralization caused by exchanges and other secondary market derivative activity.
An interesting data-driven study by Blockwatch Data on the state of staking on Tezos. Lots of interesting tidbits on how XTZ holders have participated in the protocol since it launched 2 years ago:
- When published, there were 440 active validators and 56k delegators on the network.
- Of the total supply, Tezos validators stake 16.2% themselves, 63.8% of XTZ are delegated, 5.9% of all XTZ were never claimed, 1% delegate to inactive bakers, and 20% are not staking at all.
- Delegators are loyal! There is a relatively low churn rate of 2–10%, suggesting delegators stay with their validators 10–50 months on average.
- Avalanche Sale: The AVAX token sale concluded successfully raising $42m within 4.5 hours for 10% of the token supply (50% are reserved for inflationary staking rewards).
- Cosmos IBC is Coming: The first Stargate proposal that will ultimately bring Inter-Blockchain Communication functionality is being voted on by Cosmos governance. In the meantime, lead IBC architect Chris Goes wrote a post highlighting the work that is done by various organizations, and a stable new version of the Cosmos SDK (Launchpad) has been released.
- Eth2 Attacknets: The Medalla community multi-client testnet for Ethereum 2.0 phase 0 will launch Aug 4 with support by at least 4 clients. In addition, the Ethereum Foundation has issued bug bounties for white hat hackers that manage to bring down testnet versions of different clients. Check out the details here.
- SKALE Token Sale and Economics: SKALE, Ethereum layer-2 scaling solution with a unique adaptive sidechain design, will hold a public sale through ConsenSys’ new Activate platform starting Aug 17 after launching its restricted mainnet earlier this month. 125m SKL tokens will be sold through a dutch auction and remain locked until they have been staked for a minimum of 90 days (proof of use). Furthermore, SKALE’s Conner Murphy published a comprehensive blog post about the tokenomics of the network covering details on SKL staking and how SKALE sidechain pricing will adapt to utilization levels.
- Polkadot Goes Permissionless: Polkadot is now fully controlled by stakeholders after the “Sudo” module, which granted special privileges to the Web3 Foundation, was removed via governance.
