In an email exchange, Sergio proposes a solution to prove ownership of blockchain through asymmetric-time functions and discusses his work on a transaction system called DAGCoin. He mentions that the draft will be sent to Hector for analysis or may be published altogether. Meanwhile, Tamas Blummer responds to Jameson Lopp's idea about the incentives for running a node in Bitcoin. He acknowledges the indirect incentives such as having a local copy of the validated blockchain data and supporting the network. In a heterogeneous environment, validating oneself becomes more valuable, especially during hard forks. Pooled mining became possible due to the homogenous nature of the network.The discussion on validating Bitcoin transactions involves Jameson Lopp asking if there is a way to check the validity of a transaction without access to blockchain data. Some basic checks such as ensuring it's not a double-spend and that signatures match pubkeys are necessary. As an SPV node, one can request unconfirmed transactions from connected peers, but this does not guarantee inclusion in the blockchain. Nodes should accept the first proof-of-work for a transaction and discard any subsequent ones received.In an email exchange between Hector Chu and Jameson Lopp, they discuss the use of SPV and validation of unconfirmed transactions. Lopp mentions that using SPV is only for checking the validity of transactions in the blockchain. Chu proposes nodes to validate transactions that are unconfirmed and commit to the validation by doing a proof of work on them. Lopp raises concerns about the increase in data size for each transaction, which could create more contention for block space. Chu suggests stipulating that coinbase fields only hold space for a single pubkey, reducing the extra data size.In August 2015, Jameson Lopp proposes a technical solution to allow a node operator to prove they are running an honest full node that hosts the entire blockchain. He mentions the PseudoNode project on GitHub and emphasizes the importance of validating transactions to prove the honesty of a full node.The failure of consensus on how to fix the design flaw in Bitcoin's block size is discussed. Satoshi Nakamoto suggests better incentives for users to run nodes instead of relying solely on altruism. The incentives for running a node may not be obvious to the average user, but they are indirectly present. There are thoughts on improving Bitcoin to incentivize more people to run nodes and prevent centralization. Mining and transaction validation should be inseparable, and rewards should go to those running the network. Decentralization of nodes is encouraged to be closer to the location of real transaction origination.In summary, the discussions revolve around proposals for proving ownership of blockchain, the incentives for running a node in Bitcoin, validating transactions, the increase in data size for each transaction, and the need for incentivizing full node operators. The failure of consensus on fixing the block size design flaw and the importance of decentralization are also highlighted.
