TRANSFER, BURN, ATTESTATION_REWARD

Core value-movement transactions. Active from genesis (no fork required).

TRANSFER

Moves OMBRA from one account to another.

Field	Type	Notes
type	"TRANSFER"	—
from	string	Sender address (40 hex)
to	string	Recipient address (40 hex)
amount	string (bigint)	Micro-OMBRA
fee	string (bigint)	Micro-OMBRA paid to proposer
nonce	number	—
timestamp	number	—

Validation:

• to is valid 40-char lowercase hex
• state.balance(from) >= amount + fee
• Signature valid

Effect:

• state.balance(from) -= amount + fee
• state.balance(to) += amount
• state.balance(proposer) += fee
• state.nonce(from) += 1

  "signature": "..."
}

BURN

Permanently destroys OMBRA from the sender's account. Used by:

• Block proposer for PoTU (see Protocol Spec › PoTU)
• Slashing penalties

Field	Type	Notes
type	"BURN"	—
from	string	Burner (typically block proposer)
amount	string (bigint)	Micro-OMBRA to burn
reason	string	"block_energy" for PoTU, "slashing" for penalties
blockIndex	number	Block this burn belongs to
tokensConsumed	number	Sum of outputTokens + thinkingTokens in block (for PoTU validation)
nonce	number	—
timestamp	number	—

Validation:

• For reason = "block_energy": amount == max(MIN_BURN_PER_BLOCK, tokensConsumed / BURN_TOKEN_DIVISOR)
• state.balance(from) >= amount
• Signature valid

Effect:

• state.balance(from) -= amount
• state.totalBurned += amount
• state.nonce(from) += 1

ATTESTATION_REWARD

Pays a validator for attesting to a previous block. Built by the next block's proposer.

Field	Type	Notes
type	"ATTESTATION_REWARD"	—
from	string	Proposer of the new block
validatorAddress	string	Validator that attested
amount	string (bigint)	Typically VALIDATOR_BASE_REWARD = 100
blockIndex	number	Block being attested
attestationHash	string	sha256 of attestation message
nonce	number	—
timestamp	number	—

Validation:

• validatorAddress was in the active validator set for blockIndex
• attestationHash matches a known attestation signed by validatorAddress
• Same attestation hasn't been rewarded before

Effect:

• state.balance(validatorAddress) += amount
• state.attestations[attestationHash].rewarded = true
• state.nonce(from) += 1
