We saw earlier that there was a distinct difference between the best and worst performing validators. Validators will need to build reputation one way or another to attract delegators. You can increase your self-bond by delegating more Luna to your validator account. Validators are expected to hold budget executors to account to provide transparency and efficient use of funds. In practice, running a full node only implies running a non-compromised and up-to-date version of the software with low network latency and without downtime. A notable risk for anyone who stakes LUNA (regardless of being a validator or delegator) is slashing. We expect that a modest level of hardware specifications will be needed initially and that they might rise as network use increases. This means that even though each validator gains TerraSDR (SDT) with each provision, all validators will still maintain equal weight. Both are derived from account keys generated by terracli keys add. If a validators stake falls below the threshold, meaning he is outside of the 130th largest stake, he loses its status as a validator, meaning that he cannot participate actively in securing the network and wont earn rewards. This is the address used to identify your validator publicly. Jiyun Kim, CEO of blockchain solutions company DSRV, wrote an opinion post on his own behalf, detailing how the Terra team tip-toed around the idea of halting block production while Terra (LUNA) prices crashed and its TerraUSD (UST) stablecoin was depegged. DAOs: A blockchain-based replacement for traditional crowdfunding. Should a validator misbehave, each of its delegators will be partially slashed in proportion to their stake. DSRV has suffered as much as any investor because its node had collected 14 million LUNA, worth about $1 billion by May 8, which is now worth about $3 million. The bigger the fund, which is sometimes referred to as staking pool, the more chance the validator and his group of delegators will propose a block and pocket the reward from the transaction fee. 3 min read, terra Any LUNA holder can delegate his coins to a validator without needing to comply with the tough validator requirements, and still be able to earn rewards. For example. Application keys are associated with a public key terrapub- and an address terra-. In other words, validators should have skin-in-the-game. Sentry nodes can be quickly spun up or change their IP addresses. When a validator is selected to propose the next block, it must include at least precommits for the previous block in the form of validator signatures. A candidate can submit an application by creating a validator profile following the steps detailed on the official Terra website. As already mentioned, delegators can earn an annual yield of more than 6% by staking their LUNA. This shifts the burden of denial-of-service from the validator's node directly to its sentry nodes, and may require new sentry nodes be spun up or activated to mitigate attacks on existing ones. The more staking power a validator has, the more weight it has in the consensus and processes. Your PR will be reviewed as soon as possible. Columbus-3 Mainnet has the capacity for very high throughput compared to chains like Ethereum or Bitcoin. To see how the MTBF metric has changed over the last 6 months, we plot the MTBF (per validator) over time below. Initially, only the top 100 validators with the most weight will be active validators. In the future, other mechanisms will be deployed to smoothen this process as much as possible: Penalty-free re-delegation: This is to allow delegators to easily switch from one validator to another, in order to reduce validator stickiness. The top 100 validators with the highest total stake (where total stake = self-bonded stake + delegators stake) are the active validators. There are 3 main faults that can result in slashing of funds for a validator and its delegators: Double-signing: If someone reports on chain A that a validator signed two blocks at the same height on chain A and chain B, and if chain A and chain B share a common ancestor, then this validator will get slashed on chain A. This is the final step in completing a profile. Instead, they are evenly spread among validators. If you want to delegate your LUNA to another person or group of people, an easy option is to use the Terra Station Wallet the official wallet software for holding Terra assets. Validators, and by association delegators, receive block provisions, block rewards, and fee rewards. We can plot the MTBF for each validator and see what the distribution looks like below. If it is your first time creating a profile, you will be added to the Validator Directory. A full node is a program that fully validates transactions and blocks of a blockchain. They should always be up-to-date with the current state of the ecosystem so that they can easily adapt to any change. This total revenue is divided among validators' staking pools according to each validator's weight. The bonus is linear: it ranges from 1% if the proposer includes rd precommits (minimum for the block to be valid) to 5% if the proposer includes 100% precommits. Under your repo page, click the New pull request button. As such, validators have to find a balance between wait-time to get the most signatures and risk of losing out on proposing the next block. Is there a minimum amount of Luna that must be staked to be an active (bonded) validator? Across all datasets there has been a trend of decreasing reliability compared with 6 months ago. They also participate in on-procotol treasury governance by voting on governance proposals. Commit and push the information to your repo. A validators total stake is the sum of the self-bonded tokens the tokens owned and staked by the validator and the tokens delegated to the stake pool. Terra Station Checkmark/ Inclusion in Asset Repo. Besides revenue, there are scarcity incentives: Validators earn proportionally more revenue than their delegators because of commissions, and also play a major role in determining on-chain exchange rates through the Oracle, where they get rewarded with seigniorage for faithfully reporting the exchange rate. Get the full list of validators here. Amount of delegated Luna: Total number of Luna delegated to a validator. In practice, any participant in the Terra network can apply to be a validator. Validators commit new blocks in the blockchain and receive revenue in exchange for their work. Let us take an example where we have 10 validators with equal staking power and a commission rate of 1%. Running effective operation is the key to avoiding unexpectedly unbonding or being slashed. However, it also serves the purpose to collateralize the Terra stablecoins. The barrier to becoming a Terra network validator is pretty high compared with the vast majority of other staking-based cryptocurrencies. Each delegator will value validators based on their own criteria. The operator of a major validator node on Terra is displeased with how events unfolded leading to the cessation of the chain and hopes a whole new blockchain will be created to replace it. Create a New Wallet by typing a username and password (keep them secure). A high stake shows that the community trusts this validator, but it also means that this validator is a bigger target for hackers. By no means can a validator run away with its delegator's funds. Once you have the tokens in the wallet, go to the staking tab. Let's assume that the proposer included 100% of the signatures in its block. Some delegators may prefer a website that clearly displays the team running the validator and their resume, while others might prefer anonymous validators with positive track records. The initial amount of coins the validator self-bonds. We have seen that, on average over the entire validator set, validators miss blocks around once every 1.6 hours. Data sources: https://api.flipsidecrypto.com/api/v2/queries/5eebcedf-5edd-4afd-931a-5932d5fbf964/data/latest What are the different states a validator can be in? Indeed, hackers are incentivized to hack larger validators as they receive a reward proportionate to the stake of the validator they can prove to have compromised. Validators can raise funds to stake from other luna holders by delegation. Badges may be applied by the maintainers of this repo only for claims that can be validated. How can validators protect themselves from Denial-of-Service attacks. Clone the repo from your own account. If a validator misbehaves, a certain portion of its total stake is slashed (the severity of the penalty depends on the type of misbehavior). We see there is a large variation between validators, pointing towards the conclusion that there are a number of very professional outfits, and potentially some less skilled or resourced node operators on the network. There are 4 validators who operate with an MTBF of greater than 60 hours (one downtime event every 2-3 days) and there are nearly 50 who operate at less than 2 hours between each downtime event. Taking these liveness events and looking at how many, on average, each validator has had over this time (adjusting for how long the validator has been running), we can calculate an average time between downtime events for each validator. misses a vote, suffers a network outage or is offline for long periods of time he will be penalized. Note that block rewards (paid in SDT) are distributed according to the same mechanism. He now urges validators in the Terra ecosystem to reject a hard fork in favor of a brand new community-driven blockchain. The validator can use those links to connect to sentry nodes in the cloud. This is paid in any Terra currency, and is disbursed pro-rata to stake at the end of every block in TerraSDR. There is a vast difference between validators however - the best 10 validators currently miss blocks every 30 hours and the worst 10 miss one every 8 minutes. Even though there is no obligation for validators to self-bond Luna, delegators should want their validator to have self-bonded Luna in their staking pool.

As of this writing in March 2022, the threshold to become a validator is close to 152,000 luna staked, worth about $13 million. You can modify anything within your own designated validator folder, including adding image files, new folders, etc. Website and description of the validator. This does not mean that the validator has custody of its delegators' Luna. Profiles for Validators of the Terra Blockchain. What is the incentive to run a validator ? Krisztian Sandor is a reporter on the U.S. markets team focusing on stablecoins and institutional investment. Through Terra Station (check the Terra website to download), a user can delegate Luna to a validator and obtain a part of its revenue in exchange (for more detail on how revenue is distributed, see What is the incentive to stake? Columbus-3 Mainnet enforces the parameter that each validator sets. Initial commission rate: The commission rate on block provisions, block rewards and fees charged to delegators. Let's take a concrete example to illustrate the aforementioned concept. Delegators have the same state as their validator. It turns out, that on average, it happens pretty often - once every 1.6 hours for each validator (see table below). Denial-of-service attacks occur when an attacker sends a flood of internet traffic to an IP address to prevent the server at the IP address from connecting to the internet. Another name for this metric is Mean Time Between Failure (MTBF) - a common metric in Asset Management. Be aware that being a delegator is not a passive role. This is a transition state from bonded to unbonded. He said at least 1,000 Singapore citizens have invested in Luna and UST. Then, within each validator's staking pool the revenue is divided among delegators in proportion to each delegator's stake. As such, we recommend that the data center nodes only connect to trusted full nodes in the cloud or other validators that know each other socially. To gain the bonded validator state, he has to have one of the 130 largest stake pools. A user on reddit claimed to have sent a police report have been made against Do Kwon, on behalf of UST and Luna investors. What can validators expect in terms of operations? validators. On May 8, a sell-off of UST tokens sparked a panic, ultimately leading to the price of LUNA to fall from $73 to a minuscule $0.000000999967 on Friday, according to CoinGecko. Ultimately, as the network becomes more used, one can realistically expect daily bandwidth on the order of several gigabytes. Validator's name (also known as the moniker). Address to identify your validator publicly. Delegations are not necessarily bonded. Note though, that the Terra team will not approve or conduct any audit itself. To understand more about the proposer selection process in Tendermint BFT consensus, read more in their official docs. If ever a validator's total stake dips below the top 100, the validator loses its validator privileges and no longer serves as part of the active set, entering unbonding mode and eventually becomes unbonded. Performing the same analysis on the worst 10 validators (by downtime events) we can see why the average is so low. Registered validators (validators who have submitted a profile) can opt in to receiving support from Terra by putting their contact information in a profile.json file. If you decide to stop staking and withdraw your tokens, there is a 21-day waiting period until you will receive them. He holds BTC and ETH. There is no minimum. The most recent week average MTBF for this group is around 8 minutes, and there is a distinct downtrend from 6 months ago when this number was as high as 1 hour. A validator's operator key is directly tied to an application key, but uses reserved prefixes solely for this purpose: terravaloper and terravaloperpub. The top five validators charge a 5-10% commission fee for their work something that needs to be factored in when calculating delegated staking returns. As LUNA has attracted investors' attention, more and more exchanges started to list the token in their offerings. Luna is one of the most popular coins for staking and lets users earn passive income by locking up their LUNA tokens. To do so, the candidate broadcasts a create-validator transaction, in which they must submit the following information: Validator's PubKey: Validator operators can have different accounts for validating and holding liquid funds. Because the links to the sentry nodes are in private IP space, an internet based attacked cannot disturb them directly. Apart from these criteria that will be displayed in Terra Station, there will be a possibility for validators to signal a website address to complete their resume. Application keys: These keys are created from the application and used to sign transactions. Each validator is free to set its initial commission, maximum daily commission change rate and maximum commission. Copy the template README.md and JSON Profile into your folder inside validators/. It is associated with a public key terravalconspub. That can amount to losing a small portion of staked funds, including the delegators stake, or getting completely excluded from consensus voting, which means that no rewards can be earned. Here are potential options: The Terra team does not recommend one solution above the other. CoinDesk is an independent operating subsidiary of Digital Currency Group, which invests in cryptocurrencies and blockchain startups. A validator with higher amount of self-bonded Luna has more skin in the game, making it more liable for its actions. https://api.flipsidecrypto.com/api/v2/queries/7013252f-a0fe-43b2-abea-b4f42e319210/data/latest At the end of every block, the compute fees are disbursed to the participating validators pro-rata to stake. For example, if the total bonded stake across all validators is 100 Luna, and a validator's total stake is 10 Luna, then this validator will be chosen 10% of the time as the proposer. How can I increase my "self-bond"? Each proposer is selected deterministically, and the frequency of being chosen is equal to the relative total stake (where total stake = self-bonded stake + delegators stake) of the validator. Change the contents and add your information as necessary. A complete profile including a Terravaloper and a contact email in the profile.json file must be submitted in order to receive a checkmark in Terra Station. Be aware, however, that yields may change in the future. New profiles are manually reviewed by the repo owner and a second reviewer approves the addition to the Station Assets Repo. In order to constrain Luna inflation, the protocol burns market swap spread fees and distributes a part of seigniorage to the exchange rate oracle ballot winners, which return Luna supply toward target. Any participant in the network can signal their intent to become a validator by creating a validator and registering its validator profile. One recommended way to mitigate these risks is for validators to carefully structure their network topology in a so-called sentry node architecture. The validator that is selected to mine the next block is called the proposer, the "leader" in the consensus for the round. Luna is the native staking token for the Terra Proof-of-Stake chain, and represents mining power.
