getting the ethereum-vm to spawn a new blockchain

wanderer> first create a blockchain instance https://github.com/ethereumjs/ethereumjs-vm/blob/master/tests/blockchainRunner.js#L17
<wanderer> then a new VM https://github.com/ethereumjs/ethereumjs-vm/blob/master/tests/blockchainRunner.js#L19-L22
<wanderer> add some blocks to your vm https://github.com/ethereumjs/ethereumjs-vm/blob/master/tests/blockchainRunner.js#L68-L70
<wanderer> [edit] add some blocks to your blockchain https://github.com/ethereumjs/ethereumjs-vm/blob/master/tests/blockchainRunner.js#L68-L70
<wanderer> then run the vm on the blockchain https://github.com/ethereumjs/ethereumjs-vm/blob/master/tests/blockchainRunner.js#L79-L81

todo.md

• Have one ethereum-vm state dump (so that we can verify that the js impl can load it correctly
• Add two endpoints to the JSON-RPC
  • getRawBlock
    • currently only:
      • https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_getblockbynumber
      • https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_getblockbyhash
      • but it doesn't return the whole block
  • getRawTransaction
    • currently only https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_gettransactionbyhash (doesn't include the signatures)
• Add a libp2pNode to go-ethereum, that exposes two protocols
  • /eth/block - works like bitswap
  • /eth/tx - rebroadcast to the network

Notes:

• The JavaScript implementation of ethereum can't connect to the rest of the ethereum network due to the changes in the network protocol (61 to 62)
  • node-blockchain-server is broken because of this
• ethereum JSON-RPC doesn't return full blocks or transactions (therefore, no way to check signtures)
• JSON-RPC docs https://github.com/ethereum/wiki/wiki/JSON-RPC

@diasdavid do we need to reply with which blocks we're sending you? or can you just guess by hashing them?

@whyrusleeping: yep :)
