Is there any incentives to run a full node without being one of the 21 block producer?

for a normal user to run a full node on his PC? If we define a "normal user" as Average Joe, who would like to just transfer some tokens or even deploy a smart contract, then there are not many ...

How often/consistent are blocks on EOS?

Blocks on EOS are produced every 500ms (milliseconds) by Block Producers, or BPs for short (sometimes known as Witnesses or Delegates). Unlike Bitcoin and other PoW coins, EOS uses DPoS (Delegated ...

How often/consistent are blocks on EOS?

Blocks are produced turnwise by so called "block producers" within the Delegated Proof of Stake protocol. This prevents all "miners" from rushing for the right hash like it is done ...

Is there any incentives to run a full node without being one of the 21 block producer?

Aside from monetary incentives, the primary incentives for running your own node would be speed of access to the information in the block, and the ability to run custom plugins that are needed to ...

How Does Round Robin BP Selection Work In EOSIO?

Every chain can choose to implement this however they like. On the EOS Mainnet The round robin is deterministic, and cycles alphabetically through each of the block producers. This actually causes ...

Why is the difference of current block height and irreversible block higher than 180?

Last irreversible block (LIB) is the way of providing BFT finality assuming at least 2/3+1 honest producers. However, a single confirmation from a BP is not sufficient proof to contribute to making an ...

Can EOS be run with one node?

Yes, one BP is enough. $ nodeos --producer-name eosio --enable-stale-production should be enough to start producing blocks on a chain with one node.

In a DPoS system if the majority of producers become corrupt how does the community vote them out?

The network would indeed be in trouble if over 2/3's of the Block Producers are corrupt and collude together. However, this is quite a big if statement, especially when compared to Proof of Work ...

What would happen when a block producer fails to produce its blocks when it's his turn?

There would just be blocks missing at those time points, and the next BP will build on top of what they know to be the block of highest height. Relevant section from the whitepaper: The EOS.IO ...

How transactions are broadcasted to Block Producers?

Each Node in the Network adds a list of peers it communicates with to exchange data. When a transaction is sent to a node, it is passed on to the peers and this way broadcasted to the entire network ...

Is there any need of holding EOS tokens by Dapp users?

Any event (action) that occurs on an eosio chain is at least a part of a transaction. The transactions are sent to a node that either belongs directly to a block producer, or will be forwarded to one. ...

What will happen with database and inline transaction when a transaction doesn't get 2/3+1 in the end?

Overview If a transaction is introduced in a block that never achieves 2/3+1 confirmations, it means there's likely a fork where at least 1/3 of the BPs are building blocks on. In this case, the ...

Is it possible to produce more than a block for a block producer at the same scheduled time?

Even if it's possible, it wouldn't matter. There's mostly more than one valid block. Fork-db tracks all different valid reversible blocks producers agreed to. Longest Chain wins. That's why it takes ...

What would happen when a block producer fails to produce its blocks when it's his turn?

AFAIK, if a block producer fails to produce a block, the next BP takes over after a timeout. If a BP fails to produce blocks over a certain amount of time, he can be removed from the BP list by other ...
