Jeffrey Wilcke	f0cbebb19f	core: added basic chain configuration ... Added chain configuration options and write out during genesis database insertion. If no "config" was found, nothing is written to the database. Configurations are written on a per genesis base. This means that any chain (which is identified by it's genesis hash) can have their own chain settings.	9 years ago
Jeffrey Wilcke	14013372ae	core: Added EVM configuration options ... The EVM is now initialised with an additional configured object that allows you to turn on debugging options.	9 years ago
Jeffrey Wilcke	342ae7ce7d	core, core/vm, tests: changed the initialisation behaviour of the EVM ... The EVM was previously initialised and created for every CALL, CALLCODE, DELEGATECALL and CREATE. This PR changes this behaviour so that the same EVM can be used through the session and beyond as long as the Environment sticks around.	9 years ago
Péter Szilágyi	0a5ee08e2b	Godeps, eth, tests: update ethash, used shared for testing	9 years ago
Ricardo Catalinas Jiménez	436fc8d76a	all: Rename crypto.Sha3{,Hash}() to crypto.Keccak256{,Hash}() ... As we aren't really using the standarized SHA-3	9 years ago
Jeffrey Wilcke	5b283663b4	core: Added new TD strategy which mitigate the risk for selfish mining ... Assuming the following scenario where a miner has 15% of all hashing power and the ability to exert a moderate control over the network to the point where if the attacker sees a message A, it can't stop A from propagating, but what it **can** do is send a message B and ensure that most nodes see B before A. The attacker can then selfish mine and augment selfish mining strategy by giving his own blocks an advantage. This change makes the time at which a block is received less relevant and so the level of control an attacker has over the network no longer makes a difference. This change changes the current td algorithm `B_td > C_td` to the new algorithm `B_td > C_td || B_td == C_td && rnd < 0.5`.	9 years ago
Jeffrey Wilcke	b6d88a0e9f	core, core/vm, crypto: fixes for homestead ... * Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests	9 years ago
Jeffrey Wilcke	4f4d2b6474	tests: updated homestead tests	9 years ago
Gustav Simonsson	371871d685	parmas, crypto, core, core/vm: homestead consensus protocol changes ... * change gas cost for contract creating txs * invalidate signature with s value greater than secp256k1 N / 2 * OOG contract creation if not enough gas to store code * new difficulty adjustment algorithm * new DELEGATECALL op code	9 years ago
Péter Szilágyi	1e806c4c77	cmd, common, core, eth, node, rpc, tests, whisper, xeth: use protocol stacks	9 years ago

Gustav Simonsson	145366c07e	tests: update JSON files, add new wrappers	9 years ago
Jeffrey Wilcke	80f26086ee	core, tests: get_hash fix ... Make sure that we're fetching the hash from the current chain and not the canonical chain.	9 years ago
Felix Lange	de8d5aaa92	core, core/state: move gas tracking out of core/state ... The amount of gas available for tx execution was tracked in the StateObject representing the coinbase account. This commit makes the gas counter a separate type in package core, which avoids unintended consequences of intertwining the counter with state logic.	9 years ago
Gustav Simonsson	1b1f293082	core/state, core, miner: handle missing root error from state.New	9 years ago
Gustav Simonsson	e1616f77c7	core, core/vm, cmd/evm: remove redundant balance check	9 years ago
Jeffrey Wilcke	7c7692933c	cmd/geth, cmd/utils, core, rpc: renamed to blockchain ... * Renamed ChainManager to BlockChain * Checkpointing is no longer required and never really properly worked when the state was corrupted.	9 years ago
Jeffrey Wilcke	361082ec4b	cmd/evm, core/vm, test: refactored VM and core ... * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * core/vm: byte code VM moved to jump table instead of switch * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * Byte code VM now shares the same code as the JITVM * Renamed Context to Contract * Changed initialiser of state transition & unexported methods * Removed the Execution object and refactor `Call`, `CallCode` & `Create` in to their own functions instead of being methods. * Removed the hard dep on the state for the VM. The VM now depends on a Database interface returned by the environment. In the process the core now depends less on the statedb by usage of the env * Moved `Log` from package `core/state` to package `core/vm`.	9 years ago

Jeffrey Wilcke	ac697326a6	core/vm: reduced big int allocations ... Reduced big int allocation by making stack items modifiable. Instead of adding items such as `common.Big0` to the stack, `new(big.Int)` is added instead. One must expect that any item that is added to the stack might change.	9 years ago
Jeffrey Wilcke	184e9ae9a8	core, tests: reduced state copy by N calls ... Reduced the amount of state copied that are required by N calls by doing a balance check prior to any state modifications.	9 years ago
Jeffrey Wilcke	846f34f78b	core/vm, tests: implemented semi-jit vm ... * changed stack and removed stack ptr. Let go decide on slice reuse.	9 years ago

Felix Lange	3f047be5aa	all: update license headers to distiguish GPL/LGPL ... All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".	9 years ago
